1. In 1976, a special purpose nuclear-powered submersible NR-1 was tasked to recover AIM-54A Phoenix missile from an F‐14 fighter plane that fell from the deck of the carrier USS John F. Kennedy (CV-67) during a NATO exercise Sept. 14. 1976.

Project 667BDRM Delfin/Delta IV-class SSBN Tula (K-114) on the surface with all 16 missile hatches open.
▶️Note the different shape of the 4 aftmost SLBM hatches no. 13-16.
Here's a short🧵covering this particular design solution:

When the Soviet SSBNs surfaced through the Arctic ice, the slight up-bubble trim caused most of the ice blocks to accumulate over the aftmost missile hatches, hence the need for the reinforced hatches strong enough to drop the ice blocks off of the missile deck.

The 4 aftmost hatches on Tula (K-114) were redesigned and reinforced as a part of a project codenamed Vodopad (Waterfall) by the Rubin Design Bureau, after gathering data and experience on the older Project 667B Murena/Delta I & Project 667BD Murena-M/Delta II-class SSBNs.Image

Resurrecting one of my older threads again.
This time it's a horror story, short🧵:

1. Soviet submarine K-320 was a Project 670 Skat/Charlie I-class nuclear-powered, guided missile submarine (SSGN). Designed by the famous Lazurit design bureau, Charlie-class submarines were made to carry out surprise attacks on the Western/NATO high-value naval assets such as the aircraft carriers and CSG components.Image
@CovertShores @AlexLuck9 @SubBrief @USN_Submariner @TheSubHunter1 @mikeplunkettuk @IBallantyn @The_Lookout_N @RSS_40 @FPSchazly 2. Charlie I-class 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 a variety of torpedoes & decoys. Image
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, with the submarine still on the slipway, a serious radiological accident occurred on January 18.

Project 949A Antey/Oscar II-class nuclear-powered cruise missile submarine (SSGN) Orel (K-266) in a drydock.
Note the hollow propeller shaft🧐
Following is my older thread focused on the issues she faced with her shafts👇Image
2/14
Orel (K-266) propeller shafts were initially made of a shorter hollow shafts coupled together with bolts & couplings.
The inside was filled with fine quartz sand - the reason for the hollow shaft was that it was easier to manufacture, lighter & cheaper than a solid shaft.
3/14
Hollow propeller shafts filled with fine sand also help to dampen vibrations & noise.
Alas, this wasn't the case for Orel. One of the prerequisites for the hollow shafts to function as designed was the use of lightweight propellers, but the technology to manufacture...

 Russian Navy reportedly expressed interest in the Project "Strazh" (Guardian/Sentinel) submersible patrol ship designed by the Central Design Bureau "Rubin", as recently announced by the General Director Igor Vilnit/TASS. Image
@CovertShores @TayfunOzberk @FORONAVAL @R_P_one @AlexLuck9 @TheSubHunter1 @SubBrief @USN_Submariner @The_Lookout_N @KaptainLOMA 2/5
Project "Strazh" design was first unveiled in April 2021 and included two options.
- 1st version displaces ~1000t with length of up to 70m and a crew of up to 42, including an swimmer team. The ship carries SDVs, as well as a drone and there are no weapons installed. Image
@CovertShores @TayfunOzberk @FORONAVAL @R_P_one @AlexLuck9 @TheSubHunter1 @SubBrief @USN_Submariner @The_Lookout_N @KaptainLOMA 3/5
- 2nd version displaces ~1,300t with length of 72m and a new hull shape reducing radar signature and a new engine that allows it to reach speeds of up to 21 knots. Image

 Coming back to my earlier tweet showing the Project 667BDRM Delfin/Delta IV-class Tula (K-114) transiting on the surface with all 16 missile hatches open --> note the difference in the 4 aftmost hatches no. 13-16.

Given today's announcement of the Russian MoD to scrap Project 971I/Akula-class nuclear-powered attack submarine "Nerpa" (K-152), here's a thread covering her history riddled with serious accidents.
👇 Image
@CovertShores @AlexLuck9 @IBallantyn @TayfunOzberk @FORONAVAL @TheSubHunter1 @SubBrief @USN_Submariner @RSS_40 @The_Lookout_N 2/12
Project 971 Shchuka-B/Akula-class nuclear-powered attack submarine "Nerpa" was laid down in 1993 at Amur Shipyard in Komsomolsk-on-Amur. Construction works continued until 2002, when the construction was halted due to lack of funding at roughly 70% of hull readiness.
@CovertShores @AlexLuck9 @IBallantyn @TayfunOzberk @FORONAVAL @TheSubHunter1 @SubBrief @USN_Submariner @RSS_40 @The_Lookout_N 3/12
In 2004 Russian MoD agreed with the Indian Navy to complete the submarine according to the Project 971I technical specs with handover to the Indian Navy in 2009.
Multiple issues caused postponements & "Nerpa" was launched in 2006, with outfitting works lasting another year.
