According to the news on the 13th of the "Theater" column of the US "Power" website, the US Navy recently released a rare photo showing that the US Navy's "Tennessee" strategic nuclear submarine, together with an avant-garde strategic nuclear submarine of the British Royal Navy, was sailing somewhere in the Atlantic Ocean. According to Power, this is the latest case of an extremely unusual exposure involving the US Navy's strategic nuclear submarine. Just in October, the United States Navy made public the deployment of the "West Virginia" strategic nuclear submarine in the Arabian Sea. Subsequently, the "Rhode Island" strategic nuclear submarine paid a visit to the Royal British Navy base in Gibraltar. In general, the US Navy rarely exposes the deployment of strategic nuclear submarines, because these nuclear submarines are a key part of the United States' deterrent capability for secondary nuclear strikes. Like the United States, the British military is more secretive about the deployment of avant-garde strategic nuclear submarines. The Royal Navy of the United Kingdom has only four such strategic nuclear submarines. The US media said that an E-6B "Doomsday Aircraft" appeared in the picture together with the two strategic nuclear submarines. This air command aircraft is designed to communicate safely with Ohio class strategic nuclear submarines and other US strategic nuclear strike forces, and can also give orders to launch nuclear strikes when necessary. Reported that the Royal Navy's avant-garde nuclear submarines regularly went to the US Navy's Atlantic shooting range near Florida for training, including the routine test firing of Trident D5 submarine launched missiles. According to the United States Navy, the strategic nuclear submarines of the United States and the United Kingdom have conducted bilateral maritime training aimed at verifying operational tactics, technologies and procedures, strengthening the unique alliance between the United States and the United Kingdom, and supporting deterrence and collective security. The Ohio strategic nuclear submarine of the US Navy and the avant-garde strategic nuclear submarine of the British Royal Navy are both equipped with the Trident D5 submarine launched ballistic missile designed by the US. An Ohio class carries 20 Trident D5 missiles, while an avant-garde class carries 16 such missiles. (Outlook New Times)
