Pentagon discloses location of nuclear submarine in rare move

The Pentagon has publicised the location of a secretive nuclear submarine in a move that can be read as an act of strategic signalling to Iran.

The Ohio-class vessel turned up in Gibraltar, a British colonial possession in the Mediterranean.

US Fleet Forces Command published an image of the unnamed vessel in port on 12 May with the caption:

The port visit demonstrates U.S. capability, flexibility, and continuing commitment to its NATO allies. Ohio-class ballistic missile submarines are undetectable launch platforms for submarine-launched ballistic missiles, providing the U.S. with its most survivable leg of the nuclear triad.

And Navy Lookout posted images of the submarine being towed by tugboats.

UK outlet, Defence Journal, wrote:

The visit is notable for the fact that it was publicly announced at all as the locations of U.S. nuclear-armed submarines are among the most closely guarded secrets in the American military, and public disclosure of a ballistic missile submarine’s whereabouts is exceptionally rare.

Political website, the Hill, pointed out that the reveal came at a crunch point in the Pakistan-brokered US-Iranian peace deal — “a day after President Trump rejected the latest peace proposal from Iran”.

Its reporter added:

The Pentagon did not disclose the name of the submarine, one of the U.S. military’s most secretive weapons. In general, the locations of U.S. nuclear-armed submarines are highly classified.

Pentagon’s disclosure comes amid crunch talks

The unnamed boat is part of a fleet of Ohio-class vessels with a range of capability, the Hill reported.

The Ohio class is made up of 14 ballistic missiles and four guided missile submarines. The submarines are able to carry Trident II ballistic missiles and can conduct extended deterrence patrols. The guided missile submarines can have more than 150 Tomahawk missiles on board.

Keir Starmer has said he has only involved the UK in defensive measures in the Iran war. Iran has derided that claim and Starmer’s own defence minister has contradicted it too.

The UK announced destroyer HMS Dragon was deployed to help open up the Strait of Hormuz on 11 May. Afterwards, the UK military also announced that a new drone system would be deployed.

A press release said the military package would include:

Advanced autonomous mine hunting equipment, including capabilities to detect and defeat mines.

Additionally:

The Royal Navy’s modular ‘Beehive’ system which can deliver high-speed, autonomous Kraken drone boats allowing the multinational force to sense, track, and identify potential threats and defeat them.

The UK will also send Typhoon fighter jets and mine clearance personnel. The military again claimed the multinational plan was “strictly defensive in nature” and “is designed to restore confidence for commercial shipping” along the strait.

The US and Israel attacked Iran first on 28 February without provocation. Iran was offering unprecedented concessions in negotiations at the time.

The Pentagon has since stated there was no imminent threat from Iran. The UN’s atomic watchdog, the International Atomic Energy Agency (IAEA), has also said there is no evidence Iran was developing a nuclear weapon.

The US has achieved none of its original war aims. Once attacked, Iran predictably closed the Straits of Hormuz, a vital oil channel, triggering a global energy crisis.

Iran has explicitly said the war will continue until “the enemy’s inevitable and permanent humiliation, disgrace, regret, and surrender”.

Trump came to power on an anti-war ‘America First’ ticket. He now faces worldwide humiliation.

The US’ decision to signal a submarine’s location is very unusual. The fact that the Trump administration has failed in its war objectives, and badly needs an off-ramp, makes the disclosure look desperate. US posturing won’t change the reality of the Iran stalemate.
