    Hypergolic fuel fumes are toxic and the substance is corrosive. Plus it ignites in contact with water or moist air.
    Not exactly what you would want in a submarine.

    Solid fuel is safer but it can still ignite. A bit like a powder keg.

    The main incident with Soviet SSBN hypergolics was the loss of K-219 in 1986, when a Pr.667A Yankee-I class was lost after an explosion of a R-27/SS-N-6 missile following a leak of seawater into a missile tube. It resulted in 4 deaths' and the loss of the boat (which now sits at the colossal depth of 6kms, along with its full complement of 16x 1MT warheads, plus whatever nuke torpedoes she may have been carrying).

    The distribution of such incidents is abnormal. If liquid fueled missiles were at risk for spontaneous fires, then over a 40 year period spread over tens
    of submarines there would have been many more cases. Sabotage should never be excluded.

    Not at all... liquid fuelled rockets with storable liquids can be loaded into a sub empty and therefore handling is totally safe. Once the missiles are on board the sub they can then be fuelled up safely.

    It is a myth that solid propellants are safer than liquids both are highly volatile materials designed to nearly explode in normal use.

    Hypergolic fuel fumes are toxic and the substance is corrosive. Plus it ignites in contact with water or moist air.
    Not exactly what you would want in a submarine.

    There are no nuclear missiles that are safe and biodegradable...

    Sorry to nit-pick but I think you mean the Ohio class? The LAs are attack subs.

    Yeah, that...

    The main incident with Soviet SSBN hypergolics was the loss of K-219 in 1986, when a Pr.667A Yankee-I class was lost after an explosion of a R-27/SS-N-6 missile following a leak of seawater into a missile tube.

    Old sub and old missile.... if you listened to western BS every Soviet sub has a fire burning right now...

    The US had their problems with liquid oxidisers too... look up the PEPCON distaster... that killed two and injured about 300...

    MOSCOW, January 14. / TASS /. The strategic submarine missile cruiser "Dmitry Donskoy" of project 941 (code "Akula") can be withdrawn from the Russian Navy not earlier than in five years. This was reported to TASS on Thursday by a source in power structures in northern Russia.

    "For 2021, combat training activities are planned with the cruiser. The decommissioning of the missile carrier is a question of at least five years," the source said.

    Earlier, the head of Sevmash, Mikhail Budnichenko, said in an interview with the factory magazine Zavod about the signing in 2020 of a contract for the construction of two more strategic missile carriers of Project 955A (code - Borey-A), one of which will be named Dmitry Donskoy. According to a TASS source, the construction cycle of such boats takes 7-8 years from the moment of laying.

    Hopefully the Russian Navy will decide to preserve one of the Typhoon/Akula as a museum? It would be such a waste if they were all cut up and disposed. Sad

    What's amazing is how much of this has been a regular occurrence. There's been no less than 4 of these flubs over the past year, and you'd think they'd at least have access to Wikipedia? They must of had consulting from CNN or something.

    The largest operating submarine in the world - the project 941 nuclear submarine " Dmitry Donskoy " - will serve in the Russian Navy until the reactor runs out of nuclear fuel, or another 3-4 years, RIA Novosti reports citing a source in the shipbuilding industry.

    “The strategic nuclear submarine TK-208 will remain in the operational composition of the fleet until the full depletion of fuel in its nuclear reactor. Reloading the core of the submarine's reactor is not planned. According to preliminary estimates, the ship will completely deplete nuclear fuel within the next three to four years, after which a final decision will be made on its presence in the Navy, ”the shipbuilders said.

    The reloading of the Dmitry Donskoy nuclear reactor is assessed as unprofitable given the age of the submarine - the TK-208 of the Akula class was launched in 1980. Now the Russian Navy is expecting the laying of two new class submarines "Borey-A" - "Prince Potemkin" and "Dmitry Donskoy".

    After they are put into service, the TK-208 will most likely be mothballed for subsequent disposal along with the same Sharks (Severstal and Arkhangelsk) in the Sevmash Bay in Severodvinsk.

    TASS on how Soviet designers created the world's largest submarine cruiser

    40 years ago, on December 29, 1981, the acceptance certificate was signed for the Dmitry Donskoy (TK-208) heavy nuclear missile submarine, the famous head Akula - Project 941 submarine. structure of the United Shipbuilding Corporation).

    Ohio carried 192 initially, and START treaty means Russia balanced its triad, sort of how US is doing now with Columbia , overloading the water component exposes the country to a countervalue strike on population centers, while ground component means at least some of enemy nuclear force must be aimed at silos and infrastructure
