    There was a major accident in Soviet history with hypergolic propellant rockets. The Nedelin disaster.
    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...

    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 The strategic submarine missile cruiser "Dmitry Donskoy" of project 941 (code "Akula") can be withdrawn from the Russian Navy not earlier than in five years.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

    I made a quick graphic to show just how large the #Russian Navy TYPHOON Class #Submarine really is.

    According to this Dmitry Donskoi will become museum ship in Arkhangelsk

    On the bucket list. One of the most mind blowing things humankind has ever created.

    With 200 warheads it would be hard to argue that its not the most powerful weapon ever deployed by humanity.
