LRASM-A Concept
(click to view full)

The US Navy is beginning to acknowledge a growing problem that threatens its freedom of the seas: its strike reach is shrinking and aging, while potential opponents’ attack reach is expanding and modernizing. As new designs replace older planes, US carrier aircraft range is shrinking to 1950s levels. Meanwhile, its anti-ship and land attack missiles are generally older, medium-range subsonic designs like the Harpoon Block I, which are vulnerable to air defenses. In contrast, China is deploying supersonic SS-N-22 “Sunburn” missiles bought from Russia, and working on a DF-21 anti-ship ballistic missile. The Sunburn is just one of Russia’s supersonic anti-ship missile options for sale, and a joint venture with India has added the supersonic PJ-10 BrahMos.

The math is stark: enemies with longer reach, and better weapons, may be able to create large “no go” zones for the Navy in key conflict areas. In response, think-tanks like CSBA are proposing ideas like AirSea Battle, which emphasizes a combination of advance hardening, more stealth and long-range strike options, and a progressive “blinding and grinding” campaign of strikes and interdiction. Success will require some changes to America’s array, beginning with the missiles that arm its ships and aircraft. Hence LRASM: the Long Range Anti-Ship Missile, with a secondary land-strike role.

LRASM: The Program Goals & Technology AGM-158 JASSM
(click to view full)

The joint DARPA/ US Navy LRASM program was initiated in 2009 to deliver a new generation of anti-ship weapons, offering longer ranges and better odds against improving air defense systems. Rob McHenry, a program manager in the Tactical Technology Office at DARPA, explained it this way to Aviation Week:

“We want US Navy cruisers and destroyers to be able to stand off from outside of potential adversaries’ direct counter fire range, and be able to safely engage and destroy high value targets they may be engaging against from extended range, well beyond potential adversary ranges that we may have to face… “Once the missile flies that far, it has a requirement to be able to independently detect and validate the target that it was shot at. Finding that target, the missile will have to be able to penetrate the air defenses and finally, once it gets to that target, it has to have a lethal capability to make a difference once it gets there.”

The US military is also expecting an environment where enemies try to jam or destroy the GPS system and encrypted datalink transmissions, compounding its difficulties in targeting opponents if it can’t get many of its platforms through advanced air defenses. Those considerations underline the importance of autonomous targeting. Beyond their anti-jamming digital GPS, therefore, LRASM will also rely on a 2-way data link, a radar sensor that can detect ships (and might also be usable for navigation), and a day/night camera for positive identification and final targeting.

LRASM began as the rapid development and demonstration of 2 very distinct variants. Although it’s tempting to see them as an air-launched and a ship-launched variant, ultimately, both designs were intended for launch from either ships or aircraft:

LRASM-A. Lockheed Martin is basing this design on their stealthy, subsonic, turbofan-powered AGM-158B JASSM-ER (Joint Air-to-Surface Standoff Missile – Extended Range) cruise missile, which doubles the AGM-158 JASSM’s range to over 500 miles. The JASSM program has had more than its share of performance problems, but tests in 2010 saved the AGM-158 JASSM for continued production.

Lockheed Martin Missiles and Fire Control has overall responsibility for LRASM. Lockheed Martin Mission Systems and Training manufactures the Mk-114 booster hardware, and the MK 41 VLS used aboard ships around the world. Lockheed Martin Information Systems and Global Solutions collaborates with several Navy laboratories to develop and integrate the Tactical Tomahawk Weapons Control System used on designed ships.

JASSM is an air-launched weapon, but LRASM-A’s air or surface-launch options will make it a close counterpart to JASSM’s top rival, MBDA’s Storm Shadow/ Scalp Naval.

PJ-10 BrahMos
(click to view full)

LRASM-B (Deferred). Envisioned as a ramjet-powered supersonic ship-launched missile, similar to earlier conceptions of hypersonic programs like the now-defunct RATTLRS. It’s intended to leverage prior ramjet development activities, and one of its challenges will be a suite of supporting sensors and avionics that can operate effectively at the temperatures created by high-Mach ramjet speeds. The most comparable missile out there is probably the Indo-Russian PJ-10 BrahMos, a Mach 2.8 heavy strike missile that can hit ships or land targets. Like LRASM-B, a Brahmos variant is currently being adapted for air launch as well. Unlike LRASM-B, there are also plans to put BrahMos on submarines.

LRASM-B development was much riskier from a technical point of view, and the harsh nature of high-Mach environments would add extra risk to its manufacturing and test phases, too. Those risks are normally attractive to DARPA, but in this case, they led the agency to step back and focus on the less risky LRASM-A.

Current Focus: LRASM Development LRASM-A from Mk-41
(click to view full)

Phase 1. Preliminary designs of the LRASM-A and the LRASM-B variants were successfully completed by Lockheed Martin Missiles and Fire Control. DARPA determined that it provided sufficient confidence in the 2 designs to support an investment in flight testing.

Phase 2. Awarded in 2010 to continue the development of both missiles, and culminate in flight demonstrations of tactically relevant prototypes of LRASM-A, LRASM-B, and the common sensor system from BAE Systems. A series of tests will cover key subsystems, including propulsion, sensors, and mission execution software. Detailed designs, analytical assessments and developmental test results will culminate in critical design reviews (CDR), ensuring that each design is ready to continue on to flight demonstration.

P2 Testing shift. LRASM-A was programmed now execute 3 air-launched demonstrations in 2013, and 2 surface-launch demonstrations in 2014. The common sensor system was flight tested in July 2012, but by that time, the sub-sonic LRASM-A was the program’s only survivor. In January 2012, as Lockheed Martin puts it:

“DARPA decided to focus more resources on the mature LRASM-A program, and defer further development on LRASM-B.”

LRASM-B had been set to complete the 4 shipboard Vertical Launch System (VLS) demonstrations, so Lockheed Martin began investing company funds in an LRASM-A variant that could be launched from its Mk.41 VLS. That was followed by a 2013 DARPA contract which added surface-launch development funds, and scheduled 2 initial VLS test firings.

The Future: Service Handoffs and OASuW LRASM
click for video

LRASM’s problem is that a US Navy filled with very high cost ship designs, and a looming fighter shortage on its carriers, may well decide to give missiles short shrift – even if they’re badly needed. Rick Edwards, VP of Tactical Missiles and Combat Maneuver Systems at Lockheed Martin Missiles and Fire Control, hopes that isn’t the case:

“Both of our LRASM solutions will deliver extraordinary range, willful penetration of ship self defense systems and precise lethality in denied combat environments… The maturity of these weapons and technologies allows near term transition to Navy magazines at an affordable price. These are low risk, practical options…”

His firm needs to prove that, because a big opportunity is waiting in the wings. The US Navy has budgeted about $1.13 billion from FY 2013-2018 for its “Offensive Anti-Surface Warfare (OASuW) Weapon Dev program” to replace the xGM-84 Harpoon anti-ship missile. OASuW’s priority and budgets jumped sharply in the FY 2014 submission, even as the US Navy discarded the concept of an interim weapon based on the xGM-109 Tomahawk long-range cruise missile.

OASuW Increment 1 authorized a limited buy of air-launched LRASMs on Feb 3/14. Production missile purchases will begin in FY 2017, after LRASM has been integrated with Navy F/A-18E/F Super Hornet fighters and USAF B-1 bombers.

OASuW Increment 2 will address ship-launched requirements. Harpoon anti-ship missiles were removed from all American frigates many years ago, and haven’t been installed in DDG 51 destroyers since Flight IIA began with DDG 79. The lack of anti-ship missiles on American surface combatants is becoming a problem, and likely cuts will make it a bigger problem as the USN looks to cut operating costs by cutting expensive ships like cruisers. A vertically-launched anti-ship and land strike missile that removed the need for dedicated launchers topside would solve this problem.

The Competition Tomahawk MIC promo

LRASM won’t be alone in competing for the OASuW Increment 2 opportunity.

Kongsberg’s new NSM/JSM is a stealthy cruise missile whose variants can launch from ships, or internally from the F-35 stealth fighter. They tried to compete for OASuW Increment 1 in 2014, and were an obvious candidate for an American OASuW partnership. Next time, they’ll bid with Raytheon as their Increment 1 (air-launched) partner. There’s still a partnership slot open for Increment 2, or Kongberg could use its own resources to develop a variant that works with shipboard Mk.41 vertical launch systems.

Raytheon has already tried to compete their JSOW-ER for OASuW’s air-launched Increment 1, but next time, they’ll be teamed with Kongsberg to offer the Joint Strike Missile. They remain committed to their xGM-109 xGM-109 Tomahawk cruise missile for OASuW Increment 2, for ships that carry strike-length Mk.41 VLS cells. Recent Tomahawk upgrades have added an ESM seeker that locks onto radar or other signal emissions. That would give the long-range missile some moving target capability on land, and some anti-ship capability at sea. Wider upgrades under discussion could add a radar seeker for full “maritime interdiction capability,” as an upgrade to existing stocks of over 2,000 missiles. Upgrades offer a low-cost option, but Tomahawk’s drawback is its lack of stealth, which affects its expected ability to penetrate ship defenses.

MBDA has their air-launched Storm Shadow stealthy cruise missile, which has already been used in combat. Their Scalp Naval/ MdCN is a related missile for use from ships and submarines.

Boeing holds the current Harpoon contract, and has created a stealthier Harpoon alternative in the AGM-84K SLAM-ER. Indeed, the US Navy launched production of Boeing’s SLAM-ER following its pullout from the original JASSM program, and JASSM serves as LRASM-A’s design base. Boeing could unveil further improvements, develop something new, or find a foreign partner.

ATK’s propulsion and missile expertise could also make them a factor, especially if they find a foreign partner with a cutting-edge missile.

Contracts & Key Events

DARPA picked 3 vendors for this program. BAE Systems Information and Electronic Systems Integration in Nashua, NH would design the onboard sensor systems. Lockheed Martin Missiles and Fire Control Strike Weapons in Orlando, FL would demonstrate the LRASM-A subsonic prototype. Lockheed Martin Missile and Fire Control Tactical Missiles in Grand Prairie, TX was to demonstrate the LRASM-B supersonic prototype, but that part of the program was “deferred.”

FY 2015

Chokepoints
(click to view full)

Oct 11/14: American A2/AD. Rep. Randy Forces [R-VA-4] sends a letter to Army Chief of Staff Gen. Odierno on the eve of the AUSA conference, pushing for the Army to set up a modern version of its Coastal Artillery: long-range, land-based anti-ship missiles that would be forward-based in friendly countries to endanger Chinese vessels and shipping. Missiles like LRASM and the longer-ranged but less stealthy AGM-109 Tomahawk are obvious candidates for this sort of thing, significantly outranging competitors like Kongsberg’s Naval Strike Missile or Boeing’s SLAM-ER. The RAND study that Forbes refers to actually posited using shorter-range missiles like NSM, but its maps also showed the number of deployment sites required for effective coverage.

The idea would be a nice turnabout on China’s Anti-Access, Area Denial (A2/AD) strategy, and a Philippine deployment would produce a very tangible benefit all by itself, at low cost. On the other hand, Rep. Forbes probably underestimates the difficulty of getting many countries beyond the Philippines to accept an inherently provocative deployment whose use is technically beyond their control. Recent American waffling around the world suggests an even less palatable conclusion: the penalty for saying yes would be immediate, without any assurance that the weapons would actually be used to help the accepting country if push came to shove.

Contrast with the Russian approach. They just sell SS-N-26 shore batteries to interested countries, helping customers to create the same barrier under their own control, without the offsetting political challenges. India’s derivative PJ-10 BrahMos missile may also wind up being used this way, if India can get its act together on the export front.

FY 2013 – 2014

Contracts begin for air-launched LRASM; Surface-launched LRASM-A gets the green light; Industrial expansion suggests optimism. LRASM-A Concept
(click to view full)

July 2/14: Lockheed Martin in Orlando, FL receives a maximum $200 million cost-plus-incentive-fee contract for the LRASM Accelerated Acquisition program. $33 million in FY 2014 RDT&E funds are committed immediately. This effort will prepare LRASM missiles for use from Navy F/A-18E/F Super Hornet fighters, and USAF B-1B bombers, in time to coincide with initial LRASM buys that begin in FY 2017.

Work will be performed in Orlando & Melbourne, FL; Troy, AL; Nashua, NH; Boulder, CO; and Cincinnati, OH, with an expected completion date of July 6/16. The USA’s Defense Advanced Research Projects Agency (DARPA) in Arlington, VA manages this contract (HR0011-14-C-0079).

OASuW-1 integration

March 26/14: Yes competition. Just not immediately. Navy acquisition chief Sean Stackley says that the initial buy of 90 LRASM missiles from FY 2017 – 2019 is a special justification and authorization buy following DARPA development, in order to deploy the air-launched version on USAF B-1 bombers (which will already have JASSM integrated) and USN F/A-18E/F Super Hornet fighters. US budgets actually show 110 missiles from FY 2017 – 2019 (q.v. March 4/14).

That sole-source buy has sparked a GAO protest from Raytheon re: its JSOW-ER, which it argues offer comparable capability at lower cost. The cost assertion is correct, but the capability assertion is not, given that LRASM’s offers almost twice the range at twice the speed. The real question for the Navy is how much capability it really needs, something that’s beyond the GAO’s purview.

However that shakes out, Stackley says that the US military plans to compete OASuW Increment 2 after that. The most important aspect of that program involves launch from ships’ Vertical Launch Cells, in order to correct a tactical Navy deficit that is becoming strategic. Raytheon will have to either offer an upgraded Tomahawk, which it should be on track to do by FY19, or substantially improve JSOW-ER’s capabilities. Kongsberg’s Naval Strike Missile may also have new capabilities by that time. Sources: Reuters, “U.S. Navy plans competition for next-generation missile” | USNI, “Navy to Hold Contest for New Anti-Surface Missile”.

March 20/14: No competition. Inside Defense reports that the Pentagon has rejected bids from Kongsberg (NSM/JSM) and Raytheon (presumably improved Tomahawk), and has approved Lockheed Martin’s LRASM for a major follow-on development contract to prepare it for production in FY17 as OASuW. Sources: Inside Defense, “DOD Expands LRASM Development, Rebuffs Alternate Bids From Raytheon, Kongsberg”.

March 4/14: FY15 Budget. The USN unveils their preliminary budget request briefings. They aren’t precise, but they do offer planned purchase numbers for key programs between FY 2014 – 2019. The briefing pegs FY 2017 as the beginning of low-rate LRASM production: 30 in FY17, 40 in FY18, and 40 in FY19. Source: USN, PB15 Press Briefing [PDF].

Feb 27/14: Industrial. Lockheed Martin breaks ground on a 62,000 square foot annex to its Pike County Operations’ Long Range Strike Systems cruise missile production facility in Troy, AL. When it’s complete, the facility will have expanded its existing space by 67%. The annex is supposed to be done by Q1 2015.

The Pike County facility builds AGM-158 JASSM/ JASSM-ER missiles, and also produces test missiles for the Long Range Anti-Ship Missile (LRASM) development program. While there is foreign interest in JASSM, an expansion of this magnitude suggests that the firm expects LRASM/OASuW to become a program in its own right. Sources: Lockheed Martin, “Lockheed Martin Breaks Ground on New Cruise Missile Annex at Award Winning Facility in Alabama”.

Jan 15/14: Testing. Lockheed Martin announces that a company-funded no-launch test “demonstrated and validated” that LRASM can be launched from any strike-length MK 41 Vertical Launch System, using the existing Tactical Tomahawk Weapons Control System (TTWCS) and a Mk-114 booster with modified software.

The firm says that they’ve invested $30 million of their own funds to accelerate LRASM Initial Operational Capability on the USN’s Arleigh Burke Class Aegis destroyers. Which is just a number. What’s really important is the claim that they can upload some software, and sell the USN a missile and booster that lets them mount LRASM in any of their destroyers without waiting for a major maintenance interval, or spending money beyond the missiles themselves. That kind of proposition ensures that rivals like Raytheon’s non-stealthy BGM-109 Tomahawk Block IV, or Boeing’s xGM-84 non-VLS Harpoon missile family, have no opening to make minor changes and tout themselves as a “good enough” naval alternative. Sources: Lockheed Martin, “Lockheed Martin Successfully Tests LRASM MK 41 Vertical Launch System Interface”.

Nov 14/13: Testing – Air Launch. The 2nd air test goes well, as a LRASM is dropped by a B-1B bomber, navigates through all planned waypoints with in-flight targeting updates from the Weapon Data Link, then identifies and hits a moving naval target while under autonomous guidance. Sources: Lockheed Martin, Nov 14/13 release.

Sept 17/13: Testing – Ship Launch. Lockheed Martin announces that the 1st LRASM vertical launch has been successful. In a privately-funded test aimed at the OASuW opportunity, the Boosted Test Vehicle (LRASM BTV) used a Mk-114 rocket motor from the firm’s VL-ASROC anti-submarine rocket to blast the missile out of a MK-41 Vertical Launch System canister at White Sands Missile Range, NM. The test vehicle then performed a normal guided flight profile, and subsequent examination showed no exit damage to the missile or its coatings.

The US Navy hasn’t had a vertically-launched anti-ship missile, and the absence of anti-ship missile launchers on new destroyers and on the Navy’s frigates/Littoral Combat Ships is a growing problem. In many ways, this private test was more important than the official air launch.

Sept 9/13: Testing – Air Launch. Lockheed Martin announces a successful LRASM test against a floating target at Point Mugu, CA, from B-1 launch, through autonomous navigation, to low level descent and impact. It’s an encouraging result, and further tests will presumably add to the complexity by using moving targets, etc. Source: Lockheed Martin, Sept 9/13 release.

JSOW-ER test

June 20/13: OASuW. Raytheon VP Harry Schulte discusses OASuW at the 50th Paris Air Show. The firm contends that JSOW-ER will offer a 300 nm air-launch strike weapon at a 67-75% cost savings over LRASM, and touts an anti-ship variant of their GM-109 Tomahawk cruise missile.

In terms of ship-launched weapons, the GM-109’s survival depends on its flight profile rather than its stealth. The Navy’s decision not to pursue an Interim OASuW based on the RGM-109 Tomahawk (q.v. April 10/13) suggests that it’s seen as inadequate against future defenses. On the other hand, there’s an legitimate argument to be had over air-launched weapons. The JSOW-ER’s 200 nautical mile range penalty and slower flight speed are operationally significant, but the US Navy has just begun to see budget cuts. In difficult budgetary times, adopting a much more expensive weapon in the name of “commonality” is a poor decision for the US Navy, unless the difference in air-launched performance justifies the decision. That may be so here, but it’s a case the US Navy should need to argue. Flight Global.

June 3/13: Testing. Lockheed Martin is touting successful vertical launch tests for LRASM-A, but that’s an overstatement. They ran 4 tests proving that the missile can push through the VLS cover without damaging itself, ran a missile-to-canister fit check, and conducted an integrated test of the weapon control system and VLS. All useful steps, but baby steps. Lockheed Martin.

May 13/13: Testing. Lockheed Martin announces that JASSM-ER has successfully completed USAF Initial Operational Test and Evaluation (IOT&E), scoring 20/ 21 successful flights covering all operational flight modes, at the full range of release conditions from the B-1B. Its success has clear implications that extend to the LRASM-A, which is based on the JASSM-ER. Lockheed Martin.

April 10/13: FY 2014 Budget. The President releases a proposed budget at last, the latest in modern memory. The Senate and House were already working on budgets in his absence, but the Pentagon’s submission is actually important to proceedings going forward. See ongoing DID coverage.

The OASuW Harpoon replacement program gets a sharp boost in this budget. Not only does planned FY 2014 spending jump from $44.3 million to $136 million, but overall budgets from 2014 – 2017 jump by a total of $300 million, as full ramp-up moves forward to 2014 instead of 2017. This increase holds true even though the program is canceling plans for an interim solution based on Raytheon’s xGM-109 Tomahawk long-range cruise missile.

Current plans involve Technology Demonstration (TD) contracts for the full solution in FY 2013, with follow-on competitive prototyping if required in FY 2015. If it isn’t necessary, OSAuW would jump right to a FY 2015 Engineering & Manufacturing Development phase, with a Critical Design Review in fall 2016, and a run-time to the end of FY 2017. Operational Testing would then begin in FY 2018.

March 21/13: LRASM-A. The Pentagon announces the 2nd contract component of Lockheed Martin’s March 5/13 announcement. Lockheed Martin in Orlando, FL receives a $54.4 million cost plus fixed fee contract modification for additional risk reduction efforts, before 2 planned LRASM-A launches from a MK.41 VLS. $16.6 + $54.4 = $71 million.

Work will be performed in Orlando, FL (84.13%), Baltimore, MD (14.24%), and Walled Lake, MI (1.63%) until Dec 31/14. The Defense Advanced Research Projects Agency manages the contract (HR0011-09-C-0096).

March 5/13: LRASM-A. Lockheed Martin announces $71 million in DARPA contracts related to LRASM-A. Discussions with Lockheed clarify that this announcement includes the $16.6 million contract announced on Oct 1/12, plus an additional $55 million that covers ongoing development work and 2 new requirements.

The ongoing work involves risk reduction efforts like electromagnetic compatibility testing, and follow-on captive carry tests of the sensor suite.

One new requirement is a 3rd air-launched flight test from a B-1B “Bone” bomber, in addition to the 2 scheduled flight tests under the original contract. Those flight tests are expected to take place in 2013. The second new requirement involves further development of LRASM-A’s surface launch configuration, en route to 2 surface-launched LRASM-A flight tests scheduled for 2014.

Development of that surface-launched version is actually underway already, thanks to Lockheed Martin’s investment of its own money. DARPA’s LRASM-A Phase 2 contracts to date amount to about $131 million.

Oct 1/12: LRASM-A. Lockheed Martin in Orlando, FL receives a $16.6 million cost plus fixed fee contract modification under the joint DARPA/ONR Long Range Anti-Ship Missile (LRASM) demonstration program. It pays for additional risk reduction efforts before the initial flight test of the AGM-158 JASSM derived LRASM-A, and apparently includes a 3rd air-launch test from a B-1B bomber.

Work will be performed in Orlando, FL (97.97%); Crestview, FL (1.40%); Santa Clarita, CA (0.63%); and Bothell, WA (0.003%), and will run until Sept 13/13 (HR0011-09-C-0096).

Sept 3/12: Not to B. Aviation Week reports that DARPA and the Navy have quietly cancelled the supersonic LRASM-B, as of January 2012. It adds that:

“Full-up tests of an air-launched Lrasm test vehicle are planned for early 2013, followed by tests of a vertically launched variant in late 2014. In the long term, the Jassm-based system could compete against a Tomahawk derivative for a future multipurpose missile.”

LRASM-B canceled

July 16/12: Testing. Lockheed Martin announces that the common LRASM sensor suite has successfully completed its 1st captive-carry flight off the coast of northwest Florida, detecting, classifying and recognizing targets from various altitudes and speeds. The sensors were mounted on a modified Sabreliner business jet, and target data processing algorithms ran real-time in the missile electronics. Ownership of the Sabreliner wasn’t specified, but LRASM sensor suite designer BAE Systems does own a T-39A flight test aircraft.

Testing and validation of subsystems is on schedule, and is expected to lead to All-Up-Round LRASM-A flight tests in early 2013. Lockheed Martin.

Dec 16/10: LRASM-A. Lockheed Martin Corp. in Orlando, FL receives a $60.4 million cost plus fixed-fee contract modification to execute the sub-sonic LRASM-A’s Phase 2, which will end with 2 LRASM-A air-launched demonstrations.

Work will be performed in Orlando, FL (89.47%), Melbourne, FL (8.94%) and Buffalo, NY (1.59%), and is expected to be complete in February 2013. The US Defense Advanced Research Projects Agency manages the contract (HR0011-09-C-0096). See also Jan 20/11 Lockheed Martin release for both Nov/Dec contracts.

LRASM-A Phase 2

Nov 30/10: DARPA formally announces [PDF] that it has sufficient confidence in the 2 missile designs to support further investment for flight testing, and the program will move on to Phase 2.

Phase 2 OK for both

Nov 10/10: Lockheed Martin Corp. receives a $157.7 million cost plus fixed-fee contract modification for the supersonic LRASM-B’s Phase 2, culminating in 4 demonstration launches from Mk.41 Vertical Launch Systems (VLS).

Work will be performed in Grand Praire, TX (71.32%); West Palm Beach, FL (12.53%); Broomfield, CO (5.85%); Litchfield Park, AZ (2.87%); Baltimore, MD (2.05%); East Aurora, NY (2.01%); Elkton, MD (1.24%); Portland, OR (1.23%); and Melbourne, FL (0.92%); and is expected to be completed by April 2013. The US Defense Advanced Research Projects Agency manages the contract (HR0011-09-C-0097).

LRASM-B Phase 2

July 20/09: Lockheed Martin Corp. in Grand Prairie, TX receives a $10 million cost plus fixed fee contract for Phase 1 of the Long Range Anti-Ship Missile demonstration program.

Work will be performed in Grand Prairie, TX (69%); West Palm Beach, FL (12%); King of Prussia, PA (8%); Plymouth, MN (8%); Baltimore, MD (1%); and Skokie, IL (2%), and is expected to be complete in April 2010. DARPA issued a solicitation in Federal Business Opportunities on June 6/08, and DARPA received 9 proposals, which reportedly included bids from key rivals ATK, Boeing, and Raytheon.

FALCON HTVs
(click to view full)

The path toward a hypersonic space plane has been a slow one, filled with twists and turns one would expect given the technological leap involved. Speeds of Mach 8+ place tremendous heat and resistance stresses on a craft. Building a vehicle that is both light enough to achieve the speeds desired at reasonable cost, and robust enough to survive those speeds, is no easy task.

Despite the considerable engineering challenges ahead, the potential of a truly hypersonic aircraft for reconnaissance, global strike/ transport, and low-cost access to near-space and space is a compelling goal on both engineering and military grounds. The question, as always, will be balancing the need for funding to prove out new designs and concepts, with risk management that ensures limited exposure if it becomes clear that the challenge is still too great. In October 2008, the US Congress decided that FALCON/Blackswift had reached those limits. That decision led to the program’s cancellation, though some activities will continue.

The FALCON Hypersonic Vehicle: Technical Challenges SR-72/ HTV-3X tech

The famous SR-71 Blackbird, which cruised at “only” Mach 3, made heavy use of titanium and had to use slip fits instead of rivets in many places, so that the plane wouldn’t tear itself apart when 800-900 degree surface temperatures made it expand. On the ground, and when being refueled shortly after takeoff, the plane would reportedly leak like a sieve until speed and heat had given the airframe its requisite fit.

While the state of the art has advanced since then, so have the desired speeds – and the accompanying challenges.

Making more advanced powered hypersonic aircraft work was always going to take some fancy technologies – and ongoing American interest in military initiatives like “Prompt Global Strike” may yet lead to renewed funding. Engines that can boost a plane to hypersonic speeds are very different, however, as metals tend to melt at the temperatures created by air friction at Mach 9. On Oct 8/06, journalist David Axe offered some insights, back when HTV-3 was still a live goal:

Engineers are improving on this so-called “combined cycle” to propel the Falcon, using a more powerful “scramjet” in place of the ramjet. “We need propulsion that transitions seamlessly from Mach 0 to Mach 9 or 10,” says Lockheed Martin’s Bob Baumgartner.

“For low speed, we’re looking at turbine engines that can perform at speeds from Mach 0 to Mach 4, then a scramjet … that takes over anywhere between Mach 2 and Mach 4 and goes up to higher Mach numbers — depending on the fuel, up to Mach 10,” says Steven Walker, a Darpa researcher. “For sure, we know how turbines work, but we don’t have turbines that work at Mach 4.”

“The scramjets are still at a low-technology readiness level,” he adds. “Combining both flow-paths and looking at how you transition from one to the other and the transition back … that’s all new, break-through technology.”

“Thermal protection … is the next major enabling technology,” Baumgartner says, referring to ways of coping with the high temperatures that Mach-10 flight generates. “We’re looking at durable metallic thermal protection panels to withstand heat and keep it away from structure. We’re also looking at ceramic panels.”

These technologies have uses in a variety of systems, including hypersonic missiles. That’s why research in these areas hasn’t stopped, even if HTV-3 is no longer on the planing board. “DARPA’s Hypersonic Vulcan Engine Meld” covers a program aimed at researching those kinds of advanced combined engine technologies.

The FALCON Hypersonic Vehicle: Industrial Teams HTV, top view

Lockheed Martin has reportedly completed conceptual design of an HTV-3X demonstrator. The are also performing subscale tests of the combined-cycle propulsion system, and have ground-tested inlets and nozzles that are shared by the high-mach turbine and the ramjet.

At this point, Lockheed Martin appears to have secured a team for the main bid that also includes Boeing and ATK.

Rolls-Royce and Williams International are developing candidates for the 13-inch diameter high-Mach jet turbine.

A round-combustor dual-mode ramjet under development by Pratt & Whitney Rocketdyne will be used as the ramjet, once the turbine has accelerated the vehicle to a high enough speed.

The FALCON Hypersonic Vehicle: Program History & Changes Falcon HTV Concept
(click to view full)

The HTV (Hypersonic Technology Vehicle) became a joint program involving DARPA and the U.S. Air Force Research Laboratory. It is just one part of the broader DARPA/USAF FALCON program for lower-cost access to space. HTV-1 is part of DARPA’s larger FALCON (Force Application and Launch from Continental US) program that includes the HTV and military spaceplane efforts, and also the Small Launch Vehicle (SLV) program for cheap, responsive rocket launches. AirLaunch LLC’s innovative QuickReach C-17 based launch technology is part of the SLV program, as is SpaceX’s Falcon rockets, which have gone on to more success.

In their Jan 27/06 article “High-speed air vehicles designed for rapid global reach,” the USAF promised that:

“…in September 2007, the Falcon HTV-1 is set to complete its inaugural voyage over the Pacific Ocean. Attaining Mach 19, the vehicle will briefly exit the Earth’s atmosphere and re-enter flying between 19 and 28 miles above the planet’s surface. Demonstrating hypersonic glide technology and setting the stage for HTV-2 represent the primary focus of the lower risk, lower performance initial flight.

…For the second demonstration, scheduled for 2008 or 2009, the Falcon HTV-2 will feature a different structural design, enhanced controllability and higher risk performance factors during its high-speed journey. Like its predecessor, the system will reach Mach 22 and then finish its one-hour plus mission over the Pacific Ocean… As of January 2006, HTV-1 is beginning construction.”

According to a May 30/06 Flight International report, however, technical difficulties forced a change in schedule. DARPA and prime contractor Lockheed Martin decided not to build and fly the two planned HTV-1 craft, after subcontractor C-CAT experienced delamination problems with the curved leading edges of the carbon-based aeroshell. Instead, they have shifted efforts to a different HTV-2 design whose multi-piece aeroshell has thinner leading edges, and will be easier to build because it’s less of a technical stretch. Meanwhile, thermal protection research will continue.

As the Flight International article notes, these developments had effects on the program’s schedule:

“The change will delay a first flight from 2007 for the HTV-1, to late 2008 for the first of two ground-launched, expendable HTV-2s. These will be followed by a reusable HTV-3 closer in design to the objective hypersonic cruise vehicle (HCV). The Mach 10 HTV-3 will be unpowered, but Walker says DARPA has received funding to develop and ground test a propulsion system for the HCV.

Walker says Lockheed has selected a high-Mach turbine engine and supersonic-combustion ramjet (scramjet) for a combined-cycle powerplant enabling the HCV to take off from a runway and accelerate to a hypersonic cruise. Tests of the “inward-turning” inlet and scramjet are planned for later this year [2006].”

HTV-3, at least, seemed to retain a great deal in common with the January 2006 USAF article’s description of a reusable Falcon vehicle:

“On the other hand, the third and final Falcon HTV, slated for 2009, will be a departure from the previous demonstrations. The reusable hypersonic glider will lift off from NASA’s Wallops Flight Facility at Wallops Island, Va., and then more than an hour later, be recovered in the Atlantic Ocean.

In addition, the HTV-3, flying at Mach 10, will be designed to achieve high aerodynamic efficiency and to validate external heat barrier panels that will be reusable.”

That proved a bridge too far, for now. In the end, HTV-3 was canceled, and FALCON flights were restricted to rocket-carried, unpowered test vehicles. There were to be 2 HTV-2 launches, in 2010 and 2011, costing about $308 million. Following the failure of the 1st such test in April 2010, the fate of the 2nd test was uncertain, but DARPA appears ready to go ahead.

FALCON Hypersonic Vehicle: Contracts & Key Events

Unless otherwise specified, all of these contracts are issued by the Defense Advanced Research Projects Agency (DARPA) to Lockheed Martin Aeronautics Co. in Palmdale, CA.

June 3/15: The Air Force is reportedly working on a new hypersonic test vehicle, with the aim of developing the new vehicle by 2023. The Air Force and DARPA are hoping to build on a previous 2013 test, with the X-51A WaveRider intended to be used as a proof of concept.

Nov 16/10: What happened to HTV-2? An independent Engineering Review Board (ERB) says the problem was more yaw than expected, which turned into a roll that was too fast for the autonomous flight control system to handle. The programmed response to that was “flight termination” via a forced roll and pitchover directly into the ocean, which is what happened 9 minutes into the 30 minute flight.

That’s the bad news. The good news is that DARPA got data from the flight covering aerothermal, aerodynamic, thermal protection, navigation, guidance and control; and now knows that the flight termination system works. DARPA TTO Director David Neyland thinks HTV needs tweaks rather than a full redesign, and wants to repeat the test in late 2011, after adjusting the vehicle’s center of gravity, decreasing its angle of attack (nose-up angle), and augmenting the flaps with the onboard reaction control system. Defense Update | Washington Times.

April 26/10: “Team Vandenberg launched the first Minotaur IV Lite launch vehicle at 4 p.m. April 22 from Space Launch Complex-8 here. The rocket launched the Defense Advanced Research Projects Agency’s Falcon Hypersonic Technology Vehicle 2. The 30th Space Wing commander, Col. David Buck, was the launch decision authority.”

Unfortunately, a DARPA statement said that:

“The launch vehicle executed first-of-its-kind energy management maneuvers, clamshell payload fairing release and HTV-2 deployment… Approximately 9 minutes into the mission, telemetry assets experienced a loss of signal from the HTV-2. An engineering team is reviewing available data to understand this event.”

Aviation Week adds that:

“Based on a mission timeline released by DARPA in December, the HTV-2 was between beginning reentry and starting its hypersonic glide when telemetry signals were lost.”

Feb 18/10: US FedBizOpps, opportunity #N00033-10-R-2008:

“This requirement is for the charter of one (1) US flag vessel. The period of performance, if all option periods are exercised, is estimated to be approximately 29 days. The firm period will commence on 03 April 2010, lasting for 21 days. In addition, there will be three (3) 3-day options periods. Vessel is required to provide a variety of terminal impact area support functions to an experimental Hypersonic Technology Vehicle (HTV-2) flight test that is part of the DARPA-USAF Falcon Program. The HTV-2 will be launched on a booster from Vandenberg AFB, CA to an impact near the Reagan Test Site (RTS), Kwajalein Atoll in the Marshall Islands. A launch date is planned to occur within an 8-day window lasting from April 20 through April 27, 2010. The vessel will be required to operate in close proximity to the RTS. The primary activities supported in the impact area will be (1) to transport, deploy and retrieve a set of nine impact scoring rafts, along with two Telemetry Buoys and (2) to obtain telemetry from the HTV-2 in its final seconds of flight all the way to impact from a vessel standoff distance of approximately 10 nm.”

This upcoming test is supposed to demonstrate HTV-2’s ability to withstand hypersonic heat buildup, and remain controllable. The launch rocket is expected to be a Minotaur IV Lite. FBO solicitation | WIRED Danger Room.

Oct 13/08: DARPA cancels the Blackswift reusable hypersonic testbed, after a skeptical Congress slashed the program’s FY 2009 budget from $120 – 10 million, cutting DARPA funding from $70 – 10 million and eliminating the Air Force’s requested $50 million entirely.

DARPA says it will continue with the Falcon program by flying unpowered hypersonic test vehicles in 2009, launched by Orbital Sciences Minotaur boosters in order to demonstrate their aerodynamic and structural technologies.

DARPA had hoped to award a contract for the demonstrator later in 2008, and was believed to be negotiating with a Lockheed Martin Skunk Works-led team that included Boeing. The Blackswift was expected to fly in 2012. Defense Technology International | Flight International.

July 25/08: Aviation Week’s Aerospace Daily & Defense Report reports that ATK and Boeing have joined Lockheed Martin’s “Blackswift” team for the FALCON HTV project, adding that Northrop Grumman has declined to bid.

If the reports are true, this would make it very difficult to field a credible competing team from American industry.

March 13/08: DARPA Director Dr. Tony Tether discusses FALCON during congressional testimony before the House Armed Services Subcommittee on Terrorism, Unconventional Threats and Capabilities [PDF]:

“When the U.S. Decides to act, we envision using new hypersonic vehicles to quickly reach any point on earth without the need to organize an air refueling tanker fleet to support a long-range mission. With this vision in mind, DARPA’s Falcon program has been working to vastly improve the U.S capability to promptly reach other points on the globe. A major goal of the program is to flight test key hypersonic cruise vehicle technologies in a realistic flight environment. Recently we conducted both low- and high-speed wind tunnel tests that validate the stability and control of the hypersonic technology vehicle across the flight regime. The program is also developing a vehicle test bed called Blackswift. By the end of 2012, our goal is for Blackswift to take off under its own turbojet power from a runway, accelerate to Mach 6 under combined turbojet/scramjet propulsion, and land on a runway.”

Dec 14/07: A $6 million increment of a $40.8 million modification to a previously awarded “other transaction for prototypes agreement,” as part of the Falcon HTV program’s Phase 3.

Phase 3 will include fabrication and assembly of 2 hypersonic technology vehicles to be flight-tested during 2009. Work will be performed in Palmdale, CA (9%), King of Prussia, PA (79%), and Fort Worth, TX (12%), and is expected to be completed in December 2009. Funds will expire at the end of the current fiscal year. This is a sole source award (HR0011-04-9-0010/P00032).

April 10/07: A $10.2 million modification to a previously awarded other transaction for prototypes agreement to exercise an option for the Falcon Combined Cycle Engine Technology portion of the Falcon Hypersonic Technology Vehicle effort.

Work will be performed in Palmdale, CA (20%); Philadelphia, PA (73%); and Fort Worth, TX (7%), and is expected to be complete in September 2008 (HR0011-04-9-0010, P00027).

Oct 25/06: A $33.2 million modification to a previously awarded other transaction for prototypes agreement, to continue development and demonstration of the Hypersonic Technology Vehicle portion of the Falcon program. Work will be performed in Palmdale (20%), Philadelphia, PA (73%), and Fort Worth, TX (7%), and is expected to be completed in September 2008. This agreement is incrementally funded, and this is a sole source award (HR0011-04-9-0010/P00022).

Aug 22/06: A $14.6 million modification exercises options for prototypes, as part of an agreement to continue development and demonstration of the hypersonic technology vehicle portion of the FALCON program. Work will be complete in September 2008. This Agreement is incrementally funded; no funds are being obligated at this time (HR0011-04-9-0010/P00021).

March 3/06: The University of Dayton Research Institute in Dayton, OH received a $9.9 million cost plus fixed fee contract to research heat protection for hypersonic vehicles. Solicitations began in December 2005, and negotiations were complete in February 2006. The Headquarters Air Force Research Laboratory, Wright-Patterson Air Force Base, issued the contract (FA8650-06-C-7615). As the DefenseLINK release notes:

“The Air Vehicles directorate has for several years conducted focused research on high temperature thermal protection systems that support high-speed air vehicles. The primary application of this technology is to un-powered hypersonic technology vehicles such as those being developed in the DARPA/AFSPC Falcon Program. However, this technology has many other applications to high-speed air, re-entry and space access vehicles. Ongoing research into these thermal protection systems is approximately half complete; this effort will carry the research through to completion over the next five years.”

June 27/05: An $8.9 million increment of a $19.9 million modification to a previously awarded other transaction for prototypes agreement. It exercises two options to continue development and demonstration of the hypersonic technology vehicle portion of the Falcon program. Work will be performed in Palmdale, CA and will be complete in September 2008. $2 million will expire at the end of FY 2005 (HR0011-04-9-0010).

March 16/05: A $10.6 million increment toward the DARPA/USAF FALCON program. The increment is part of a $55.2 million modification that exercises the option for Phase IIb of Task 2 (Hypersonic Technology Vehicle). Work will be performed in Palmdale, CA (41.5%) and King of Prussia, PA (58.5%) and will be completed in December 2005. $3 million of these funds will expire at the end of FY 2005 (HR0011-04-9-0010, P00006).

Aug 6/04: A $7.6 million increment of an $8.4 million other transaction for prototypes agreement. It covers Phase IIa of Task 2 (hypersonic technology vehicle) of the DARPA/Air Force Falcon program. Work will be performed in Palmdale, CA (41.5%) and King of Prussia, PA (58.5%) and will be complete in February 2005. $4.6 million of the funds will expire at the end of FY 2004. This was a limited competition among the 4 participants in Phase I of the Falcon HTV program (HR0011-04-9-0010).
