Tank or a Waterborne Vehicle?

In 1951, when the Soviet Union was on its high, authorities had an idea of building special floatation devices for tanks. First sample workpieces for T-54 tank were made at in 1952, and, some several weeks later tests were carried out on the Oka river. In the next two years trial test at the sea were conducted. And in 1957, eventually, the floatation device was passed into service.

There were supposed to be as many as 187 (according to the amount of tanks) floatation devices on the strength of the motor rifle division.

Along with that working activities of building floatation devices for T-55 and 3SU-57-2 tanks were lead. In 1959 at plants №342 and №174 there were working activities of commoning of floatation devices carried out. In 1960, an upgraded floatation device PST-U (universal one) was put into service.

PST-U consisted of five pontoons that were filled with plastic foam. Total weight of the device was 10 tonnes. Buoyancy reserve (with T-54 tank) was 40%. Maximum speed of tank with the floating device was 19 km/h ashore and 12 km/h afloat. The floating device was equipped with its own fuel tanks with a capacity of 500 litres; equal to coverage of 60-80 kilometers distance without any tank’s fuel consumption.

Water obstacles traverse could be done with sea disturbance of 5 points and tank gunnery with 1.5 points. Together with tank it was possible to carry a landing troops crew of 25 people (40 for 3SU-57-2) though gunnery with the crew aboard was prohibited. A floatation device mounting could be carried out in as less as 35 minutes and its release was performed in no time at all. PST-54 floatation device was carried by four ZIS-151 trucks.

    Neat concept. Why wasn’t it further developed?

    • D says:

      guessing that you never really need to transport just one tank over long distances on water and so it’s better to make a large transport that can carry a lot of tanks.

      Also most tanks could go under water for prolonged periods of time, so in theory they can cross most small bodies of water and it’s far more useful to use large helicopters to move individual tanks to key locations.

        “Also most tanks could go under water for prolonged periods of time…” Really? I know it’s summertime all up in here ‘an whatnot yo, but dude, tell me… what have you been smoking? I’m pretty sure that you ‘aint been hittin’ a Yava! LOLZA!

        Good point about transport efficiency. I still feel that a large number of AFVs scattered out so they aren’t as vulnerable as those carried together on a single transport would be useful in some tactical settings. Helicopters are more vulnerable than boats, anything disables their engines and they crash.

        I am glad the Hitlerites did not come up with this idea.

        I would imagine an assault on somewhere like the island of Gibralta or similarly fortified islands could be carried through by this means if local air superiority could be established for just a short period of time.

        Tanks with snorkels are limited in how deep they can go before they are drowned. They are somewhat difficult to navigate with too.

    Cool!

    5nd! Reminds me of the Bradly.

    There was a article in Russian “Popular Mecanics” not so much time ago. They said what project was canceled, primary because in modern operation, you don’t need just a few tanks. You need artillery support, infantry, ammunition and so on.
    Here is original article:

    ЗСУ-57-2 = ZSU-57-2… not 3SU :)))

  9. Вадим says:

    Это утопическая идея которая рождалась в недрах наших проектных институтов, к счастью не дошла до массового производства.
    This is a utopian idea which was born in the depths of Soviet design institutes, fortunately did not reach mass production.
