The Royal Navy currently has zero attack submarines available for operations, with all five of its Astute-class hunter-killer boats docked for maintenance or technical issues.
According to multiple reports, the entire fleet of Astute-class submarines — HMS Astute, Ambush, Artful, Audacious, and Anson — is alongside, leaving Britain without a single operational nuclear-powered attack submarine for the first time in recent memory.
