Though this has been the way with all Royal Navy submarines, they were originally designated alphanumerically, such as HMS A1 of the A-class of 1903.
The Soviet Union suffered the loss of at least four submarines during this period: K-129 was lost in 1968, K 8 in 1970, K -219 in 1986, and Komsomolets (the only Mike classsubmarine) in 1989 (which held a depth record among the military submarines—1000 m).
In this case the submarine depicted is the USS Columbia (SSN-771), an actual Los Angeles classsubmarine commissioned in 1995.
The AA-1 class was a class of three experimental submarines of the United States Navy, built toward the end of World War I, between 1916 and 1919.
These notional "fleet" submarines would necessarily be larger and better armed, but primarily, they would need a surface speed of some 21 knots (39 km/h) to be able to maneuver with the battleships and cruisers of the line.
In the ensuing authorization of eight submarines, Congress specified that one should "be of a seagoing type to have a surface speed of not less than twenty knots." This first fleet boat, laid down in June 1916, was named Schley after Spanish-American War hero Winfield Scott Schley.
