Originally, the Project 627 (NOVEMBER class) submarine was supposed to have been built for the Soviet Navy with an armament of one enormous (1550mm) nuclear-armed torpedo - the T-15 - for attacking ports and naval bases. Just two 533mm torpedo tubes, without reloads, would have been carried for self-defence.

IOTL sanity prevailed and instead the NOVEMBER class we know and love entered service. What if the backers of the T-15 concept had won through and the submarines had been built as originally designed?
