Sevastopol-class Battleship, Oktyabrskaya Revolyutsiya


Oktyabrskaya Revolyutsiya post-war

TL;DR:
Bluewater vessel, Parizhskaya Kommuna with slightly worse main guns and armour but a large amount of anti-aircraft guns and radar.

History:
The last of the Sevastopol (or Gangut) class battleships to be commissioned, and originally named Gangut, the class namesake in foreign texts. It served in the Baltic Fleet in WW1 and participated in the February Revolution of 1917 and the Ice Cruise from Helsinki to Kronshtadt. In 1918 it was laid up due to crew shortages, and later renamed Oktyabrskaya Revolyutsiya (October Revolution). It underwent repairs and a refit in the mid-1920s, re-joining the fleet in 1926.

In 1931, after the completion of Marat’s modernization, Oktyabrskaya Revolyutsiya’s was started. The fore superstructure was greatly expanded, with a stronger design compared to Marat’s, which allowed for a fire director to be added and more crew quarters. A second aft tower was constructed, which allowed a second fire director to be fitted. 2 large cranes were also mounted on the aft tower, meant for seaplanes and boats. The main battery guns were slightly modernized, which allowed for easier barrel replacement, and the turret roof armour was reinforced to 152mm. 6 76mm Lender guns and 24 7.62mm Maxim’s MGs were added as AA guns. The boilers were replaced with 12 from the unfinished battlecruiser Izmail, which were much more efficient than the originals, needing less for the same power and allowing the installation of an additional bulkhead to improve underwater protection. Work was completed in 1934, and the ship later participated in the Winter War, bombarding a Finnish coastal battery.

Its AA guns were reinforced in 1941 and the cranes removed, and at the start of Operation Barbarossa was based at Tallinn. The rapid German advance forced the ship to retreat to Kronshtadt, and minefields placed by Axis forces removed the ability of the Baltic Surface Fleet to conduct operations. Oktyabrskaya Revolyutsiya and Marat shelled German forces advancing onto Leningrad, and was badly damaged by bombs in September, knocking out 2 turrets. The ship’s repair lasted until November of 1942, and it supported the Soviet breakout from Leningrad in 1944. it was reinforced with more AA guns and armour plates during the war, and a British air warning radar in 1944. In June of that year, it fired the last combat shots of any Soviet battleship, and was awarded the Order of the Red Banner for its service.

Post-war, Oktyabrskaya Revolyutsiya remained in the fleet and was reclassified as a school battleship in 1954. In 1956 it was decommissioned, and its hull slowly scrapped over the next few years.

+1 1944 model. I like the story of an old battleship that underwent several modernizations and refurbishments and was used after WWII. Beloved ship…

+1, i think it is the most modern version of Sevastopol

Unfortunately Paris Commune is still the most modern one; it has improved reload and torpedo bulges. All October Revolution has over it is an early search radar and more AA.

what about "[Petropavlovsk], 11.1950- Волхов [Volkhov}?

Marat? It’s the least modernized of the three. Had another modernization planned but was partially destroyed in 1941.

It was also just added ingame lol.

I thought it was a further modernized version in 1950, my bad

There was a rebuild project planned post-war, but that was cancelled.

Suggestion passed to the developers for consideration.
