Spring of 1982, in the vicinity of Kings Bay. Two Soviet Project 861/Moma-class AGIs following very closely unidentified US Navy's James Madison-class SSBN.
AGI "Ekvator" (418) is in the background. Photo was taken from AGI "Seliger" (SSV-514).
@CovertShores @Capt_Navy @RSS_40 @SubBrief @USN_Submariner @The_Lookout_N @TayfunOzberk @FORONAVAL @Aviation_Intel @wachteldean54LV Call out to US submarines, anyone able to ID the James Madison-class SSBN?

@CovertShores @Capt_Navy @RSS_40 @SubBrief @USN_Submariner @The_Lookout_N @TayfunOzberk @FORONAVAL @Aviation_Intel @wachteldean54LV Update, sub class correction, it's Benjamin Franklin-class SSBN.

#Nuclear horror story, short🧵:
1. Soviet submarine K-320 was a Project 670 Skat/Charlie I-class SSGN. Designed by Lazurit design bureau, these submarines were intended to carry surprise attacks on Western/NATO high-value naval assets.
@CovertShores @Capt_Navy @RSS_40 @SubBrief @USN_Submariner @TayfunOzberk @FORONAVAL @The_Lookout_N @R_P_one @FPSchazly 2. Charlie-I SSGNs were armed with P-70 Ametist/SS-N-7 Starbright SLCMs housed in two rows of four missile tubes on each side of the bow & outside the pressure hull as well as 4x533mm & 2x400mm torpedo tubes capable to launch variety of torpedoes & decoys.
@CovertShores @Capt_Navy @RSS_40 @SubBrief @USN_Submariner @TayfunOzberk @FORONAVAL @The_Lookout_N @R_P_one @FPSchazly 3. K-320 was laid down at Krasnoe Sormovo Shipyard as K-302 on 30/04/1968, launched on 27/03/1971 & commissioned 15/09/1971.
At the beginning of 1970, the submarine was still on the slipway, when a serious radiological accident happened on 18 of January.

1. In the late 60s, Soviet submarine design bureau "TSKB-16 Volna" began designing a large nuclear-powered amphibious transport submarine, Project 717. The idea was for the submarine to travel hidden under the Arctic ice & unload troops & equipment... Image

Another #nuclear bedtime story, short 🧵:
1. Russian ROSATOM agency recently announced a plan to recover two sunken nuclear submarines: K-159 (Project 627A/November class SSN) & K-27 (Project 645/November class SSN).
@CovertShores @SubBrief @USN_Submariner @TayfunOzberk @FORONAVAL @Capt_Navy @RSS_40 @HMUboff @The_Lookout_N @R_P_one 2. K-159 was one of 12 Project 627A class SSNs - a slightly modified Project 627 Kit, that produced the first Soviet nuclear submarine Leninskiy Komsomol K-3.
Assigned to the Northern Fleet, K-159 was laid down at SEVMASH shipyard in 1962 & commissioned a year later.
@CovertShores @SubBrief @USN_Submariner @TayfunOzberk @FORONAVAL @Capt_Navy @RSS_40 @HMUboff @The_Lookout_N @R_P_one 3. K-159 was finally decommissioned in 1989 & laid up in Gremikha naval base with both of her VM-A reactors not defuelled for the next 14 years, awaiting disposal, with little to no maintenance whatsoever. The hull of the submarine deteriorated extremely over the years...

🧵A short #nuclear nightmare bedtime story!
I really shouldn't be reading this stuff before going to bed.

Following is an excerpt from "Russian Nuclear Power Plants for Marine Applications" by Ole Reistad & Povl L. Ølgaard from 2006👇 Image
@CovertShores @Capt_Navy @RSS_40 @FORONAVAL @TayfunOzberk @SubBrief @USN_Submariner @TheSubHunter1 @EmbersOfSuns @R_P_one 1. "The first Alfa-class submarine K-64 became operational in 1970, but suffered a loss-of-coolant accident in 1972 when a leak developed between the secondary water-steam circuit and the primary liquid metal circuit, exposing the primary circuit to a pressure of 70 atm. Image
@CovertShores @Capt_Navy @RSS_40 @FORONAVAL @TayfunOzberk @SubBrief @USN_Submariner @TheSubHunter1 @EmbersOfSuns @R_P_one 2. As the pressure relief system failed to function, the high pressure caused a rupture of the piping of the primary circuit. Two tons of liquid metal coolant flowed out into the reactor compartment, where it solidified. Image
