Thirty-five experts from 17 Member States as well as representatives from the EU Military Committee, the EU Military Staff, the EU Commission and NATO Allied Command Transformation participate in the European Defence Agency’s Table Top Exercise (TTX) on long term capability trends, starting today. Results of the exercise will feed into the revised Capability Development Plan (CDP) which will be presented to Ministers of Defence in the first semester of 2018.
The three day long exercise is part of the CDP revision and addresses the review of the current Long Term Trend Capability Assessment, with a perspective on 2035 and beyond. It comprises in-depth analysis and assessment of all military tasks, identifying the evolution of key military requirements, the key trends towards 2035 and beyond, the future importance of the different tasks, as well as related risks and challenges.
“Similar to previous table top exercises, we evaluate capability trends by using threat scenarios. Only this time, the elaboration of these scenarios was more complex as we are looking at trends in 2035 and beyond. We thus worked closely together with military R&T experts to elaborate scenarios including technology available in about 20 years. The aim is to derive future military capability development trends in a European setting”, says Roland Van Reybroeck, Cooperation Planning & Support Director at EDA.
The TTX will address the full scope of military tasks in view of answering the question “which capabilities will Member States’ armed forces need in 2035 and beyond?” An important aspect thereby is to analyse in detail the capability implications in different scenarios.
“If we take for example global warming and the melting of ice caps, apart from ecological and economic consequences, the military would need to look at its long term capability needs to face new geopolitical scenarios potentially resulting from climate change. In this context, military long term capability planners would for example examine related requirements for the next generation of frigates”, explains Lars-Ove Roos, Project Officer at EDA.
The key findings from this exercise, will underpin the long term dimension to the Capability Development Plan. The post-TTX analysis and assessment is to be completed by December 2017.

Modern U.S. Navy Amphibious Assault Ships project power and maintain presence by serving as the cornerstone of the Amphibious Readiness Group (ARG) / Expeditionary Strike Group (ESG). LHA/LHD are a key element of the Seapower 21 doctrine pillars of Sea Strike and Sea Basing, transporting, launching, and landing elements of the Marine Expeditionary Brigade (MEB) via a combination of LCAC hovercraft, amphibious transports and vehicles, helicopters, and aircraft.
Designed to project power and maintain presence, LHA-Replacement (LHA-R, aka. LH-X, and now the New Amphibious Assault Ship or NAAS) large deck amphibious assault ships were slated to replace the US Navy’s 6 LHA-1 Tarawa Class vessels. They are based on the more modern LHD Wasp Class design, with the LHD’s landing craft and well deck removed in favor of more planes and hangar space. While its LHA/LHD predecessors were amphibious assault ships with a secondary aviation element, it’s fair to describe the America Class as escort carriers with a secondary amphibious assault role.
The LHA-R program may have been in the works since PMS-377 was put in charge in November 2000, but it took several years to get underway as a major spending program.
LHA 6 America, the lead LHA-R vessel, was planned for delivery to the U.S. Navy in October 2013, though when that date came and went, sea trials had yet to take place. It and should be in service by 2015. The ultimate question is how many ships of class will be built. Support for the limited NAAS buy of 2 ships is already set, and LHA 7 Tripoli is due for delivery in June 2018. The question is the 3rd ship, and any ships after that.
The FY13-18 FYDP does feature a 3rd “LHA-R” ship in FY 2017, pushed back a year from the original plan. In April 2009, Gannett’s Navy Times revealed that the Marines were having second thoughts about the well deck removal, and the limitations this created for the total force. Altering ship plans for LHA 6 or LHA 7 would have been too expensive, but “LHA 8’s” planned cost, and these previous statements by the Navy and Marines, suggest that this ship will have a well deck. Low amounts allocated for LHA 8 design also indicate that any well-deck equipped ship is likely to be a fairly close derivation of an existing design. So, too, does the math inherent in the ships’ volume and internal layout limits. In other words, LHA 8 looks set to be a slightly updated variant of the all-electric LHD 8 Makin Island design. In effect, it would become “LHD 9”. This return of the well deck is later confirmed as the “Flight 1” configuration.
The ship’s timeline at the end of the FYDP makes it vulnerable to further budget cuts, and so does the higher price of a well deck equipped vessel. The FYDP has set aside $4.4 billion, compared to the Navy’s 2012 estimates of $3.2 – $3.3 billion per ship for the America Class. Time will tell whether the 3rd New Amphibious Assault Ship survives.
Note that even at that lower price, America Class ships already far exceed the cost of smaller LHDs like France’s 21,500t helicopter-only Mistral Class LHD (EUR 325M/ $485M), though the American ships are designed to naval survivability levels, and feature far more advanced defenses and launch capabilities.
A better comparison may be Australia’s 27,500t, jet-capable Canberra Class LHDs (AUD$ 1.6 billion/ USD$ 1.4 billion per), or Italy’s 27,100t Cavour Class escort carrier, which combines F-35B launch capability with housing for troops, and vehicle ramps for heavy vehicles stored inside (about EUR 1.5 billion/ $1.975 billion). Measured on a per-ton basis, their cost is not all that far off. The tactical tradeoff is that larger ships like the America Class gain new fighter spots and storage capacity faster than they grow in tonnage. On the flip side, they offer less survivability and mission flexibility than 2 Cavour Class ships might enjoy.
The LHA-R Ships: 21st Century Escort Carriers LHD Wasp ClassLHA-R/NAAS design modifications aimed to optimize aviation operations and support activities. The end product is essentially a revival of the World War 2 escort carrier concept, with integrated berthing, cargo, and light vehicle spaces for Marines.
At 844 feet long and 106 feet wide, LHA-R ships will be almost 80 feet longer than USS Wasp and 10 feet wider, since they don’t have to fit through the Panama Canal. As a result, these ships will weigh in at 45,594 long tons fully loaded, rather than LHD 8’s 41,649t full load. The Navy prefers not to call their America Class ships carriers, but will admit that they’re an “aviation centric” design. In plain English, they’re really CVL/CVE aircraft carriers with crew space for 1,204, that can also berth up to 1,686 Marines, with a possible surge to 1,800 people for short periods of time. These NAAS ships will rely on a mix of fixed-wing and rotary aircraft for most of their tasks, from close air support, to transport, to helicopter coverage.
Protection comes in 3 layers, from the medium-range Evolved SeaSparrow launchers, to the short-range RAM missile system, to close-in defenses that range from radar-guided Mk.15 Phalanx 20mm gatling guns to a range of decoy systems. Few small carriers have defenses this comprehensive, and some full-size carriers in Britain and India will also fall short by comparison. Even so, advances in modern cruise missiles makes the Navy doubt LHA-R’s survivability against a determined multi-missile swarm.
DID uses the term “escort carriers” due to their relative size compared to America’s 95,000t+ nuclear-powered supercarriers, and also due to the size of their aerial complement, which is reduced by the ship’s amphibious mission. Nevertheless, it’s worth noting that the America Class’ overall displacement is larger than France’s 43,000t FS Charles De Gaulle nuclear-powered aircraft carrier, or the American World War 2 Essex Class carriers’ 36,380t.
Like the Tarawa and Wasp classes, NAAS ships will have a flat flight deck, without a “ski ramp” on the front. With a ski ramp, V/STOL (Vertical/Short Take-Off and Landing) fighters like the Harrier, STOVL (Short Take-Off, Vertical Landing) fighters like the F-35B, UAVs, or tilt-rotor aircraft can all take off with larger loads, while using less fuel. On the other hand, a fully flat deck increases the number of deck locations available for landing or parking aircraft.
The US Navy thought hard about this choice. During the Analysis of Alternatives phase, they considered a 69,000 ton “Dual Tram Line” option with an LHD 8 sized well deck for hovercraft, an angled flight deck like an aircraft carrier’s, and a ski ramp that allows aircraft to take off with heavier loads. Existing F-35B-capable platforms that already use the ski ramp approach include Britain’s new 65,000t Queen Elizabeth Class carriers, Italy’s new 27,100t Cavour Class aircraft carrier/LHD, and Navantia’s 27,500t BPE / Canberra Class LHDs. The Navy eventually chose to pursue a design based on LHD 8 Makin Island instead, as the path of least risk and best cost containment. For good or ill, they also decided against adding a ski ramp.
Eliminating the ramp did give them a couple more “spot factors.” A ship’s possible aircraft combinations are calculated by totaling “spot factors” (SF), and amphibious ships use the CH-46E Sea Knight’s space requirements as their base (1.0). The aged Sea Knights are being phased out, however, and will not be part of the America Class’ 58.0 Spot Factor air wings. Instead, these air wings are expected to include MV-22 Osprey tilt-rotors (2.22 SF), CH-53E/K heavy transport helicopters (2.68/?), MH-60R/S multi-role utility helicopters (1.0), UH-1Y troop transport helicopters (0.94), and AH-1Z attack helicopters (0.92); and/or 6-23 fixed wing F-35B Lightning II STOVL fighters (2.0).
These new aircraft, and the MV-22 in particular, drove many of the ship’s key requirements. When one compares the “standard” complements of the LHA-R vs. the existing LHD Wasp Class, the result is about a 45% increase in required “spot factors,” for the same number of airframes: [1]
In single-role carrier configuration, America Class ships will embark 2 MH-60S helicopters for Search And Rescue, and take on 20 F-35B fighters plus all of the required spares, extra weapons, etc. Even so, the F-35B will have just 2 landing spots that can handle the heat from its engine: #7 and #9.
Floor footage wasn’t the only thing affected by the class’ escort carrier configuration. High-bay enlargement of the maintenance hangar in 2 areas was required in order to accommodate USMC MV-22s or AFSOC CV-22s, which can’t be brought in for full servicing on current LHA Tarawa and LHD Wasp Class ships.
A final aviation advantage comes from the addition of fuel tanks, in place of the ballast tanks used by the Tarawa and Wasp classes to offset the weight of a filled well deck. That more than doubles available JP-5 aviation fuel, from 600,000 gallons to a full 1.3 million gallons.
The Well Deck Issue LHA 3 launches LCACThere’s a cost to these changes.
While it’s called an amphibious assault ship, the America class lacks those ship types’ characteristic feature: a floodable well deck for launching landing craft. The US Navy and Marines initially decided that there were enough other ships in the fleet with well decks, and contended that the use of LHA/LHD ships to transport and land heavy vehicles tends to be rare anyway. They eventually changed their minds, and “LHA 8” may now include a well deck, but LHA 6 America and LHA 7 Tripoli will be built without.
Removal of the traditional well deck offers some advantages. For starters, it provides America Class Flight 0 ships with an extended hangar deck and aviation support spaces. It also lowers LHA/CVL America Class maintenance costs. In exchange, the America Class can’t launch and land medium-heavy vehicles like the USMC’s AAV7 amphibious armored personnel carriers, their future amphibious APCs; or LCAC hovercraft that can carry vehicles like M1 tanks, LAVs, and mine resistant MRAP-type vehicles ashore.
Lift-on/ Lift-off cranes, which could have mitigated this shortfall by transferring cargo to other ships, are also absent from the design. If LHA-R Flight 0 ships decide to carry heavier vehicles, or require faster offload given the 14,000+ pound empty weight of even very light mine-resistant vehicles, their sole options will be their CH-53K heavy-lift helicopters, or offloading by ramp onto a port’s docks.
Power and Influence: Secondary Ship Features Naval LM2500Propulsion and power is the same hybrid system as LHD 8, which is a plus for the Navy. It involves 2 GE LM2500+ gas turbines, each rated at 35,290 shaft horsepower at U.S. Navy standard day conditions (100 degrees F), and a pair of 5,000 hp auxiliary propulsion motors. The hybrid propulsion system enables the ship’s propellers to be driven either by the gas turbines or by electric motors, which are powered from the ship service electrical system. This allows the ship to operate in a more fuel efficient mode throughout its speed range, while being able to generate far more electricity to power onboard electronics, etc.
Finally, the new class resembles its LHA/LHD predecessors in that will be able to operate as the flagship for a full expeditionary strike group. Its enhanced and reconfigurable command and control complex will be based on the US Navy’s directive to use open architecture electronics whenever possible, in order to lower costs and make future upgrades easier.
A hospital facility complements these advanced command and aviation capabilities when assisting in humanitarian operations, and serves the amphibious combat force. It’s about 67% smaller than USS Makin Island’s [LHD 8], as a result of expanding the hangar bay.
LHA-R: Contracts & Key Events launch timelapseUnless otherwise specified, all contracts are awarded by the US Naval Sea Systems Command (NAVSEA) in Washington, DC, to Northrop Grumman Ship Systems (now Huntington Ingalls, Inc.) in Pascagoula, MS. The company’s Ingalls operations in Pascagoula, MS is where the USA’s current fleet of Tarawa Class LHA and Wasp Class LHD amphibious ships were all built.
FY 2015-2017
June 21/17: Huntington Ingalls has been awarded a $3 billion contract modification for the design and construction of the America-class Landing Helicopter Assault Replacement Amphibious Assault Ship. The majority of work will take place in Pascagoula, Miss., with further work to be carried out at smaller sites. Completion is expected for January 2024. The vessels will go towards the replacing the US Navy’s fleet of Wasp-class of amphibious assault ships.
May 8/17: Shipyard Huntington Ingalls has launched the second ship in the America-class of amphibious assault ship 13 weeks ahead of schedule. The future USS Tripoli can carry 12 Osprey aircraft and six F-35s and is fitted with .50 caliber machine guns and 20mm CWIS cannons. It can also support AV-8B Harriers, Cobra attack helicopter, cargo carriers, and other equipment. More America-class vessels are expected to be built in 2018, with the next vessel to be named after the WW2 Bougainville campaign.
April 10/17: The Navy’s USS America has successfully shot down a UAV with the Rolling Airframe Missile (RAM), during live-fire exercises designed to verify the new amphibious assault ship’s defense capabilities. During the test, the UAV posed as an anti-ship missile threat while the RAM utilized its quick-reaction fire-and-forget capabilities to down the drone. The USS America is the first vessel of its class and is designed to accommodate modern fighters such as the F-35B, alongside other vertical and/or short take-off and landing (V/STOL) aircraft and helicopters. It will support US Marine Corps aviation requirements, from small-scale contingency operations of an expeditionary strike group, to forcible entry missions in major theaters of war.
Feb 25/15: Navy to pit two yards against each other in duopolistic design competition for LHA-8, new oilers and LX(R) dock landing ship. Mindful of the trend of shipyards to consolidate to the point where there is barely the opportunity for real competition, the Navy is deliberately packaging three very different major defense acquisition programs together and selecting two shipyards to bid for each, with the explicit expectation that each will be rewarded at least one. General Dynamics NASSCO and Huntington Ingalls Industries will compete for the redesign of the LHA-8 (which sorely needs its well deck back now that Marines vehicles have plumped up); the T-AO(X) fleet oiler and the LX(R) dock landing ship replacement.
“Each shipyard will be awarded one detail design and construction contract for LHA 8 or one DD&C for T-AO(X) ships 1-6,” said a Navy representative. “This approach balances the Navy’s commitment to maintaining a viable shipbuilding industrial base while aggressively pursuing competition.” The arbitrary connection of three disparate programs and the automatic win that could go to a loser seems reminiscent of a kindergarten awards ceremony, but at least the creation and maintenance of this duopoly appears to be deliberate. It may shed light on the decision-making process as it happens for the Ingalls/BIW duopoly on the Arleigh Burke contracts and the ancient Newport News/Electric Boat rivalry for submarine work.
FY 2013-2014LHA 6 nearing completion. LHA 8 will have a well deck.
America sea trialsJuly 15/15: The Navy has reportedly issued a Request for Proposals to two shipyards for a third America-class amphibious warship (LHA-8) and six next-generation oilers (TAO(X)). The RFP was sent to General Dynamics NASSCO and Huntington Ingalls Industries, with the Navy looking to pit the two yards against one another for contracts to manufacture the first six oilers or LHA-8.
Oct 11/14: LHA 6 Commissioned. The ship is formally commissioned at Pier 30/32 during San Francisco Fleet Week.
She is the 4th ship to bear that name, with predecessors that include a schooner, a World War I transport [ID-3006], and a conventionally-powered aircraft carrier [CV 66, 1965-1996]. Sources: US Navy, Full video and “USS America Joins the Fleet”.
USS America
Aug 26/14: Visits, F-35B Prep. LHA 6 America is visiting around South America on its way to San Francisco, with 4 MV-22B Osprey tilt-rotors, 3 H-60 Seahawk helicopters, and a special purpose MAGTF (Marine Corps Air-Ground Task Force) on board. The ship hasn’t even been commissioned yet, and they’re treating the visits to Trinidad and Tobago, Colombia, Brazil, Uruguay, Chile and Peru as a training cruise.
After PCU America’s commissioning and shakedown, a Post-Shakedown Availability visit to the shipyard expects to install modifications that will let the ship safely use F-35B fighters. To achieve that, intercostal structural additions will be inserted underneath flight deck landing spots numbers 7 and 9, in order to deal with the heat produced by the F-35B’s F135-PW-600 LiftFan engine. Those changes are currently being tested on the USS Wasp [LHD 8]. Sources: Defense Tech, “USS America Tours South America, Prepares for JSF”.

June 13/14: LHA 8. General Dynamics NASSCO in San Diego, CA receives a $23.5 million contract modification for early industry involvement in the LHA 8/ LHA(R) Flight 1 affordability design phase. LHA 8 is supposed to put the well deck back, pushing the design much closer to USS Makin Island [LHD-8]. Unfortunately, the ship has seen estimates as high as $4.4 billion. If the designers can reduce that figure, the ship’s odds of surviving coming budget battles will improve.
All funds are committed immediately, using FY 2014 RDT&E budgets. Work will be performed in San Diego, CA and is expected to be complete by May 2015. US NAVSEA in Washington, DC manages the contract (N00024-13-C-2401). See also HII, “Ingalls Shipbuilding Awarded $23.5 Million LHA 8 Affordability Contract”.

April 10/14: LHA 6 Delivery. HII’s Ingalls shipyard delivers the LHA 6 America to the US Navy in Pascagoula, MS. Commissioning is set for late 2014. Sources: US Navy, “Navy Accepts Delivery of the future USS America” | HII, “Ingalls Shipbuilding Delivers Amphibious Assault Ship America (LHA 6)”.
March 31/14: GAO Report. The US GAO tables its “Assessments of Selected Weapon Programs“. Which is actually a review for 2013, plus time to compile and publish. The report cites a high degree of rework on LHA 6, and the fact that they began construction with the design just 65% complete may have something to do with that. That has raised costs, and helped make the ship’s delivery 19 months late. Another $42.4 million will be spent on rework of the ship’s deck to cope with the F-35B’s exhaust and downwash (q.v. Jan 17/12). GAO adds that:
“Although not considered critical technologies, the program has identified an additional six key subsystems necessary to achieve capabilities. Five of these subsystems are mature. The sixth, the [GPS-guided] Joint Precision Approach and Landing System, is still in development, but LHA 6 can use backup aviation control systems to meet requirements. There are no new critical technologies expected for LHA 7 or LHA 8, but requirements for LHA 8 are still in development.”
Beyond the new deck design, design changes to LHA 7 will include a new firefighting system; and updates to the radar and the command, control, communications, computers, and intelligence systems. One hopes that key survivability upgrades (q.v. Jan 28/14) are also on this list. Design changes to LHA 8 will add a well deck that can accommodate 2 landing craft, and they’re considering designs that would allow compartments to be reconfigured in low-risk areas, in order to meet changing mission needs with less rework.
Jan 31/14: INSURV. LHA 6 America completes Navy acceptance trials off the coast of Pascagoula, MS. The Navy’s Board of Inspection and Survey (INSURV) evaluated all of the ship’s major systems, including combat, propulsion, communications, navigation, mission systems and aviation capabilities. It passed with no major deficiencies, which is a real achievement for a first-of-class ship. Delivery is planned for spring 2014. Sources: US NAVSEA, “LHA 6 Completes Acceptance Trials” | HII, “Video Release — Ingalls Shipbuilding’s Amphibious Ship America (LHA 6) Sails the Gulf of Mexico for Successful Acceptance Trials”.
Jan 28/14: DOT&E Testing Report. The Pentagon releases the FY 2013 Annual Report from its Office of the Director, Operational Test & Evaluation (DOT&E). The America Class is included, and some of its deficiencies aren’t really about the ship – but others are.
It has been known for some time that the SSDS combat system needs continued improvement, and test aboard Nimitz Class supercarriers indicate that some modern cruise missile attacks will overwhelm existing defenses. The technical term is “Probability of Raid Annihilation”, and LHA-R isn’t likely to meet the goal the Navy set (q.v. Jan 17/12). Some of that is traceable to the design, however:
“LFT&E analysis completed so far identified potential problems in susceptibility and vulnerability that would likely result in the LHA-6 being unable to maintain or recover mission capability following a hit by certain threat weapons, the details of which are classified. The Navy’s required updated analysis is behind schedule jeopardizing planning for follow-on ship survivability improvements…. In particular, some fluid systems need additional isolation valves, sensors, and remote operators to allow rapid identification and isolation of damage and reconfiguration for restoration of the mission capability they support. Additionally, the egress from some of the troop and crew berthing spaces may result in crew causalities and delay damage control actions. The Navy has plans to incorporate some corrective actions for follow-on ships.”
Nov 7-9/13: Builder trials for PCU America are conducted in the Gulf of Mexico. If all goes well she is to be delivered to the Navy in March 2014. LHA 6, the 4th ship named USS America, will join the Pacific Fleet and have San Diego, CA as its homeport. Initial Operational Capability (IOC) is scheduled for September 2016. Sources: HII, Nov 14/13 release | US Navy PEO Ships, Nov 7/13 release | DefenseTech: First America-class Amphib Nears Completion.
June 2013: LHA 8. The Navy plans to complete the Preliminary Design of LHA 8 during FY13, finalize its Capability Development Document (CDD) and Concepts of Operations (CONOPS), and get started on contract design. The Senate Armed Services Committee is somewhat skeptical and recommends the addition of $20 million to the LHA-8 (i.e. flight 1) development budget because “[r]epeated Navy shipbuilding programs have shown that failing to complete a ship’s design before starting construction inevitably leads to cost growth and schedule delays.” Senate NDAA FY 2014 report 113-044 | PE 64567N budget justification [PDF].
April 2013: The FY14 President Budget still sets the order of a 3rd LHA ship to FY2017 as of the latest FYDP. The delivery of LHA 6 is however delayed by 6 months. Vice Chief of Naval Operations Adm. Mark Ferguson had testified before the Senate Committee on Armed Services in February that this delay was one of the consequences of starting FY13 under a continuing resolution (CR) preventing the start of new programs.
Schedule as of April 2014November 2012: The Navy conducts an operational assessment of LHA 6, though they don’t release any results publicly.

Jan 26/12: LHA 7 delayed. Preliminary FY 2013 budget materials discuss coming shifts in Pentagon priorities, as the defense department moves to make future cuts. The America Class is involved:
“To ensure sufficient resources to protect these strategic priorities, we will reduce the number of ships by slowing the pace of building new ships and by accelerating the retirement of some existing ships. These include… Slipping a large deck amphibious ship (LHA) by 1 year.”
See: Pentagon release | “Defense Budget Priorities and Choices” [PDF]
Jan 17/12: DOT&E report. The Pentagon releases the FY2011 Annual Report from its Office of the Director, Operational Test & Evaluation (DOT&E). The America Class is included, even though they haven’t conducted testing yet. Some of the ship’s systems have been tested elsewhere, however, and their problems affect the ship. At the same time, some aspects of the design itself are being questioned, and so is ship survivability.
The good news is that LHA 6 will likely meet its Key Performance Parameters for vehicular stowage space, F-35B capacity, vertical take-off and landing spots, cargo space, and troop accommodations; but it will have much less hospital capacity than other American LHA/LHDs. DOT&E wonders if it will be enough.
The bad news is that LHA 6’s 12,000 pound limit for the vehicle ramp from the hangar deck to the flight deck, is a serious problem. Since the America Class has no well deck and no crane, everything must be airlifted ashore. There’s no point in having a ramp that can support 70-ton tanks and 24-ton LAVs, but even an up-armored HMMWV would stress the ramp as currently designed. Worse, blast-resistant MRAP or JLTV vehicles that could be airlifted off by a CH-53K, and would be necessary for many operations, couldn’t be carried on the ship. Those limitations are magnified by DOT&E’s statement that the USN and USMC haven’t yet produced a concept of operations or concept of employment that accounts for the America Class’ lack of a well deck, or that takes advantage of its enhanced aviation capability. On which note:
“Jet blast from the F-35Bs is expected to produce unsafe forces on flight deck personnel up to 75 feet from the short take-off line. MV-22 operations produce heat levels that might damage the flight deck and overwhelm the environmental controls in the spaces immediately below the flight deck.”
A full survivability assessment report is due in FY12, but DOT&E is concerned that:
“Due to long-standing and previously identified legacy sensor limitations, LHA-6 may be vulnerable to certain airborne threat flight profiles. Based on combat systems testing on other platforms, it is unlikely that LHA-6’s Ship Self-Defense System Mk 2-based combat system (including Nulka, SLQ-32, and Evolved Sea Sparrow Missile) will meet the ship’s Probability of Raid Annihilation requirement against anti-ship cruise missiles.”
This is true, but worth deeper analysis. Part of the problem is that there’s only so much weaponry one puts on ships like this. Its armament is actually substantially stronger than foreign LHDs like the Mistral or Juan Carlos/Canberra Classes, and matches up evenly against the Italian Cavour Class light carrier and amphibious support vessel. If advances in enemy weapons create a problem, other ships will have to compensate, or the cost of each NAAS ship would become very high indeed.
In this case, however, DOT&E is citing performance shortfalls against certain threat types by the ship’s component weapons: RIM-162 ESSM, RIM-116 RAM, Nulka, SLQ-32, and the ship’s radars. The radar shortfalls are a known issue, but unless the USN opted for a foreign radar design, there’s no reasonably-priced radar option that would fix them. As for the weapons, they are a real problem for the fleet, but extraneous to this one program. The long term solution is for their capabilities to improve, or the Navy to adjust its tactics to address their weaknesses, if it can.
FY 2010 – 2011LHA 7 added to program, and lead-in buys begin; Any LHA 8 will have a well deck.
LHA 7 conceptAug 1/11: RAM. A $7.4 million contract modification for 3 refurbished and upgraded rolling airframe missile MK 49 Mod 3 Guided Missile Launch Systems with associated hardware, for use on LHA 7 (2 systems) and LCS 5 (Detroit, Freedom Class Littoral Combat Ship, 1 system).
Work will be performed in Tucson, AZ, and is expected to be complete by March 2013. Contract funds will not expire at the end of the current fiscal year (N00024-11-C-5448).
April 15/11: SAR to 2 ships. The Pentagon’s Selected Acquisitions Report ending Dec 30/10 includes the America Class under significant cost increases, for an obvious reason:
“LHA 6 – Program costs increased $3,458.9 million (+102.7%) from $3,367.9 million to $6,826.8 million, due primarily to the addition of one ship from one to two ships.”
March 31/11: LHA lead-in. A not-to-exceed $28.7 million contract modification for the procurement of additional long lead time material in support of “the LHA replacement flight 0 amphibious assault ship.” That could describe LHA 6 America, or LHA 7; timelines suggest that it probably means LHA 7.
Work will be performed in Philadelphia, PA (79.9%), and Pascagoula, MS (20.1%), and is expected to be complete by March 2014 (N00024-10-C-2229).
Oct 28/10: A $48.1 million contract modification for additional planning and advanced engineering services in support of LHA 7. Work will be performed in Pascagoula, MS, and is expected to be complete by May 2012 (N00024-10-C-2229). See also Northrop Grumman.
June 30/10: LHA 7 lead-in. A not-to-exceed $175.5 million cost-plus-fixed-fee contract for LHA 7 long-lead time material, planning, and advance engineering services. The as-yet unnamed LHA 7 will be an LHA-R Flight 0 ship just like America [LHA 6], which is now 25% complete. Long lead time materials include items like main reduction gears, which must be complete and ready to go very early in the build stage. With all contract options exercised, this contract could reach $193 million.
Work will be performed in Brunswick, GA (24.4%); locations yet to be determined (24.2%); Pascagoula, MS (23.1%); Los Angeles, CA (17.3%); York, PN (9.3%); and Brampton, Canada (1.7%), and is expected to be complete by March 2014. This contract was not competitively procured (N00024-10-C-2229). See also Northrop Grumman release.
March 30/10: GAO. The US GAO audit office delivers its 8th annual “Defense Acquisitions: Assessments of Selected Weapon Programs report. With respect to LHA-R, it says:
“The LHA 6 began construction in December 2008 with mature technologies, but [only 65%]… of its design complete… Approximately 45 percent of the LHA 6 design is based on the LHD 8. The Navy conducted two production readiness reviews to assess the shipbuilder’s readiness to commence full construction. In addition, as of September 2009, the program office had conducted unit readiness reviews for 141 of the ship’s 216 assembly units. The LHA 6 is likely to experience further cost growth because postdelivery rework of the ship’s deck may be necessary to cope with the intense, hot downwash of the Joint Strike Fighter… The Navy is planning to conduct aircraft tests on the LHD 1 during the fall of 2010, and will then determine whether the LHA 6 [and other ships that will operate it] need to modify their flight decks. The program office does not expect the Navy to finalize a solution for the LHA 6 prior to ship delivery…”
March 22/10: Gannett’s Navy Times:
“More than two years before the amphibious assault ship America enters the fleet, Marine officials have already drawn up early plans for a version of the ship that includes a major component America is missing – a well deck. The “LHA 8 concept,” as it was called in a presentation Monday by Marine Corps Combat Development Command, would combine new aviation features the Marines want in the America class with a traditional big-deck capacity for landing craft and green gear… the Navy’s most recent shipbuilding program includes no plans for such a ship… Navy Secretary Ray Mabus has said it would be prohibitively expensive to alter the designs for America or the follow-on LHA 7, so they’ll be built as planned.”
FY 2008 – 2009LHA 6 keel laid; America Class.
RIM-116 RAM LaunchAug 28/09: Well deck rethink? Information Dissemination reports that the Marines may be rethinking the removal of this class’ well decks:
“When the Marines decided to remove the well deck on the LHA (R) for USS America (LHA 6), it was a decision to move towards specialization. No surprise then that this year the Marines testified in front of Congress that the well deck will be added to future LHA (R)s as soon as possible, because just the removal of the well deck turned the LHA (R) into too much of a specialization for the Marines to overcome shortcomings in necessary sealift throughput.”
July 17/09: LHA 6 keel laid. Northrop Grumman Corporation holds the keel authentication ceremony for LHA 6 at the company’s Pascagoula facility.
Per Navy and maritime tradition, ship sponsor Lynne Pace had her initials welded onto a ceremonial steel plate noting the ship’s keel had been “truly and fairly laid.” Ms. Pace is the wife of retired U.S. Marine Corps Gen. Peter Pace, the first US Marine to Chair the Joint Chiefs of Staff. NGC release.
Oct 20/08: LM2500. GE’s LM2500+ gas turbines will power the USS America, which surprises no-one. The same engine was used on LHD-8, and its use in LHA 6 was expected from the outset. Northrop Grumman’s formal selection merely makes it official.
The LHA 6 ship’s mechanical-electric propulsion system will consist of 2 LM2500+ gas turbines, each rated at 35,290 shaft horsepower at U.S. Navy standard day conditions (100 degrees F), and a pair of 5,000 hp auxiliary propulsion motors. The hybrid propulsion system enables the ship’s propellers to be driven either by the gas turbines or by the electric motors, which are powered from the ship service electrical system. This allows the ship to operate in a more fuel efficient mode throughout its speed range, and also gives it more electrical capacity to power sensors and onboard equipment. MarineLog.
June 27/08: America Class. US Navy Secretary Donald Winter announces that LHA 6 would be named USS America when it is brought into service, a move that also names the ship class.
The new America would be the 4th ship in US Navy service to bear the name; the last such ship was CV 66, the Kitty Hawk Class aircraft carrier commissioned in 1965, decommissioned in 1996, and sunk as an 2005 experiment using explosives, torpedoes and naval gunfire. US Navy | Gannett’s Navy Times.
