A third class boat, AS-12, reached the fitting-out stage before being cancelled in 1998.^[1]

Displacing 1,580 tons submerged, the Kashalot class was constructed using a single titanium hull design, and is powered by a nuclear reactor; they were the first Soviet nuclear-powered submarines to have a single hull. The boats each have a crew of 36 officers and men.^[1] AS-13 and AS-15 were reported active as of 2016.^[2]
