 | | Royal Navy submarines classes, including ballistic missile submarines, are letter-based; thus, all boats of the Swiftsure class begin with the letter S and the Trafalgars, the letter T. 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 class submarine) in 1989 (which held a depth record among the military submarines—1000 m). |
