Ship project history


Design of I. G. Bubnov. Single-hulled, without watertight bulkheads, development of Akula. Under original design it was supposed to equip them with 2 1140hp diesels, that should ensure 19kts surface speed. However it was necessary to install diesels removed from Amur flotilla gunboats.
