Face à la pression qui montait Cheikh Hasina a démissionné dimanche, après l'échec d'un concensus avec les chefs militaires de son pays. Voici le récit de ses derniers moments au pouvoir.

Summary and Key Points: The U.S. Navy's Ohio-class ballistic missile submarines, key components of America's nuclear deterrent, typically operate under secrecy. However, in June, the unusual location disclosure of USS Tennessee (SSBN-734) surfaced in the Norwegian Sea, alongside USS Normandy (CG-60) and strategic aircraft, signaled a calculated message.

-Such disclosures are rare, given the submarines' stealth and destructive capabilities.

-This public reveal likely responded to recent Russian naval activities, including the deployment of their guided-missile frigate Admiral Gorshkov and a nuclear submarine to the Caribbean. The U.S. Navy's move underscores its deterrence strategy and readiness to counter potential threats.

Why Did the U.S. Navy Reveal the Location of a Stealthy Ohio-Class Submarine?

The United States Navy's Ohio-class nuclear-powered ballistic missile submarines remain a key component of the nation's nuclear triad and serve as a nuclear deterrent. The warships are often spoken/written about – yet rarely seen. As part of the "Silent Service," the submarines spent much of their patrols under the sea, with their locations rarely disclosed.

However, on back in June, the U.S. Naval Forces Europe-Africa/U.S. 6th Fleet posted on X – the social media platform formerly known as Twitter – to announce that USS Tennessee (SSBN-734) was operating in the Norwegian Sea, while the nuclear-powered and nuclear-armed sub was joined by the Ticonderoga-class guided-missile cruiser USS Normandy (CG-60) and P-8A Poseidon maritime patrol and reconnaissance aircraft. In addition, an E-6B Mercury strategic communications plane was also reported to be flying over ahead.

The unusual disclosure--the submarine was surfaced and not under the waves operating in stealth--of the movements of any of the U.S. Navy's 14 Ohio-class ballistic missile submarines is already highly unusual. However, the fact that an E-6B jet – one of the Navy's 16 modified Boeing 707s that serves as an airborne strategic command post and like the U.S. Air Force's E-4B is often known as a "doomsday plane" – makes it especially noteworthy.

The "boomers" as the submarines are known can disappear for months at a time. That is exactly what they were designed to do, as the boats remain the most destructive weapon system employed by the U.S. military. Given that there are just 14 in service – along with four more modified Ohio-class subs that serve as cruise missile submarines (SSGNs) – revealing the location of any isn't something taken lightly.

Yet, since 2020, the U.S. has disclosed the locations as a reminder of the Ohio class's destructive capability.

"Any decision to highlight the presence of one of these submarines, which are key components of America's nuclear deterrent arsenal and typically keep well out of sight while deployed, inherently sends a message to potential adversaries, such as Russia," TheWarZone reported.

So why did NAVEUR-NAVAF offer up the location of the SSBN-734?

The most likely answer is that it was a direct response to the Russian Navy's deployment of the guided-missile frigate Admiral Gorshkov and the Yasen-M-class nuclear-powered guided-missile submarine Kazan to the Caribbean earlier in June. The Russia flotilla – which also included the replenishment tank Academic Pashi and a tug boat Nikolay Chiker – made a rare port-of-call visit to Havana, Cuba, at the time

In addition, the Russian Navy had been conducting drills in the Mediterranean, involving its missile cruiser Varyag following another port visit to the Libyan city of Tobruk. The cruiser, which also took part in joint exercises with the Egyptian Navy, is quite far from her home port, as she is the flagship of the Russian Navy's Pacific Fleet.

Russia Freaked Out: Why the U.S. Navy 'Unretired' the Iowa-Class Battleships

Battleship vs. Battlecruiser: Iowa-Class vs. Russia's Kirov-Class (Who Wins?)

Summary and Top Line Points: The U.S. Navy's Seawolf-class submarines, developed at the end of the Cold War to outmatch Soviet capabilities, remain among the most advanced undersea warfare vessels. With only three constructed, these subs are equipped with cutting-edge technology, including Mark 48 torpedoes, Harpoon anti-ship missiles, and Tomahawk cruise missiles. The class includes the USS Seawolf, USS Connecticut, and USS Jimmy Carter, with the latter modified for special operations.

-In recent years, the Navy has publicly surfaced these stealthy subs, particularly in the Arctic, to deter Russian aggression.

As tensions continue in Ukraine, the U.S. may use similar displays to reinforce NATO's deterrence strategy.

Why the Seawolf-Class Has to Surface Sometimes 

Designed at the tail end of the Cold War, the U.S. Navy’s Seawolf-class submarines were built to surpass the capabilities of their Soviet counterparts. 

While budgetary constraints and the collapse of the USSR led to the cancellation of the full planned fleet of vessels, the three Seawolf ships constructed continue to wow naval experts and scare U.S. adversaries. In fact, the Navy’s Seawolf ships carry some of the most sophisticated undersea warfare technology ever developed.

Although submarines usually remain silent and stealthy, in order to demonstrate their ability to strike from any corner of the world, the Navy has intentionally surfaced them as a show of force to adversaries. 

In 2020, the service made public displays of its nuclear submarines in Norway in an effort to deter Russian hostility in the region. On Aug. 21, 2020, USS Seawolf parked off the coast of Tromso to take on new crew members. The U.S. and Norway use this strategic port off the coast of Tromso to keep an eye on Moscow’s Northern Fleet. According to senior naval officials, “the U.S. and Norway have a great relationship, and our ability to use facilities in and around Tromso would provide a strategic location for our visits,” adding that “It would give us flexibility for not only the U.S. but allied countries to exercise in the High North.” 

Introducing the Seawolf-Class

USS Seawolf, like its two sister ships, was developed in the late Cold War. The Navy required a new sub class capable of countering the USSR’s Typhoon class of ballistic missile submarines. Engineers designed the Seawolf ships to be quieter and faster than their predecessors. The lead ship of the class, USS Seawolf, was ordered in 1989 from the Electric Boat Division of General Dynamics. USS Connecticut was commissioned a decade later, followed by USS Jimmy Carter in 2004.

In 2021, Connecticut was severely damaged after colliding with a seamount while sailing in the South China Sea. Fortunately, no sailors were killed in the incident, but the submarine has remained out of commission since this mishap. The Navy expects to return Connecticut to service in 2025. 

USS Jimmy Carter was developed with distinct modifications, making the submarine essentially a new class when compared to its two sister ships. The Navy uniquely designed Jimmy Carter for covert surveillance and special operations missions. 

According to Business Insider, Jimmy Carter included “special thrusters fore and aft that allow the sub to remain stationary underwater, as well as a 100-ft hull extension known as the Multi-Mission Platform, which increased its length to 435 feet and its fully submerged displacement 12,158 tons.” Jimmy Carter can float above undersea communications cables and physically cut into them, which enables the submarine to intercept the data streams running through them.

Basic Specs and Capabilities for the Seawolf-Class

The Navy’s Seawolf-class ships are typically armed with 533mm Mark 48 torpedoes, in addition to Harpoon anti-ship missiles and Tomahawk cruise missiles. A Tercom-Aided Inertial Navigation System guides each missile toward its intended target. While the Tomahawk can be fitted with a nuclear warhead, these submarines rarely carry these types of munitions. 

As detailed by Naval Technology, “Block III improvements include an improved propulsion system and Navstar global positioning system (GPS) guidance capability. The anti-ship Tomahawk missile is equipped with inertial guidance and an active radar and anti-radiation homing head. The range is up to 450km.”

Could the Navy Surface Its Seawolf-Class Submarines in the Future?

As Russia’s invasion of Ukraine rages on, the U.S. and its NATO allies are constantly working to deter additional hostilities in the region. Showcasing the strength and capability of the U.S. submarine fleet via surprise surfacing missions could remind the Kremlin of the consequences of extending the war further.
