The Pentagon just let everyone know that it's got a nuclear armed submarine in the Arabian Sea, for no particularly stated reason. Just in case you were curious. The movements of nuclear submarines are usually secret, but U.S. Central Command (CENTCOM), the part of the Pentagon that oversees operations in the Middle East, just tweeted it out.

The purpose of the announcement, according to a press release, was to highlight a visiting general. "On October 19, General Michael 'Erik' Kurilla, commander of CENTCOM, conducted a visit aboard the USS West Virginia, a U.S. Navy Ohio-class nuclear powered ballistic missile submarine, at an undisclosed location at sea in international waters in the Arabian Sea," the press release said. But the seemingly random press release comes the same day the U.S. announced that Iran is not only supplying Russia suicide drones for its invasion of Ukraine, but that Iranian "military personnel" are on the ground in Crimea training Russians in how to use them.

The location of nuclear submarines is a closely guarded secret. America's nuclear weapons operate on what's called a triad. The three legs of that chair are intercontinental ballistic missiles (ICBMS) that reside in underground missile silos, submarine-launched ballistic missiles, and bombers. The idea of the submarine is that, should an enemy knock out the bombers and ICBM silos, the submarines can still launch nukes. The idea that an enemy has no idea where and if a submarine will launch a nuke is meant to deter them from launching nukes of their own.
