Project 1077 Fort 'Arsenal Ship', 1980s
During the 1970s the USSR formulated its 1981-1990 shipbuilding programme. The experience of exercises like Okean-70 had shown the need for more command facilities afloat and special fleet command ships were proposed, one for each fleet (four in all). In 1972 the Sverenoye (Northern) PKB was assigned what became Project 1077. The ship would serve as a squadron radar picket ship and command ship but in size and armament was of cruiser capability
The first design had a standard displacement of 10,000 tons, 186m long, 20m beam and a speed of 30 knots with gas turbine propulsion. A helicopter hangar in the hull would accommodate four Kamov Ka-25RLD helicopters (this project would result in the Ka-31). Self-defence armament was the M-22 Uragan SAM missile complex, an Osa-M SAM complex, one 100mm AK-100, four 30mm AK-630 and two RBU-6000.
In 1977 a more advanced version was submitted; 12,910 tons, 202m long, 22m beam, larger hangar for six Ka-31 and the armament was modernised with Fort (96x missiles) and Kinzhal (64x missiles) SAM complexes, a twin 130mm AK-130 and two 533mm five-tube torpedo launchers. Air-search radars were MR-600 Voskhod and MR-360 Podkat with the air/surface search radars being MR-500 Kliver and Fregat-M.
Insufficient space on the building slips saw the class postponed to after 1985 and then cancelled in favour of moving the command functions to other vessels and the Ka-31 fleet was assigned to the new aircraft-carrying cruisers. But that was not the end of the story, Project 1077 was revived as a platform for the Skorost medium-range ballistic missile, to create a ship analogous to the Western 'arsenal ship'. Project 1080 illustrated elsewhere on the forum was a similar competing design. Skorost is a sketchy weapon today, it is possible that it was based on the second and third stages of the Topol-M missile. Around 80% of the ship was unchanged but although the missile seems to have tested around 1987, the fall of the Soviet Union finally ended all chances of the Project 1077 being built.
I have no underwater hull sources, so rather than making them up I decided to leave them off.
The Skorost IRBM is almost unknown today, my missile is basically a Topol-M with minor changes and can only be considered speculative.
The Kamov Ka-31 is completely redrawn based on Citizen Lamba's excellent Ka-27.
