HMS Trinidad.
German destroyer Z26 was sunk by HMS Trinidad which was able to limp into Murmansk for repairs leaving Kola Inlet in May 1942, "we hadn’t been at sea for more than a few hours when we were picked up by a shadowing enemy plane, before the Junkers 88s arrived closely followed by the Dornier torpedo bombers." Attacked by over 20 Ju-88 bombers Trinidad was struck and 63 men were lost including 20 survivors from HMS Edinburgh, a decision was made to scuttle the ship, survivors were picked up by neighbouring vessels before Trinidad was torpedoed and sunk by HMS Matchless.
Mark14 Torpedo.
In the arctic in 1942 the light cruiser HMS Trinidad fired a torpedo however the bearing mechanism, like the one in the video froze because of the extreme cold and the torpedo went in a circle and hit the ship. RL254. The Mark 14 torpedo was used for most of WW2 it used an alcohol - methanol - steam boiler, the torpedo contains a 2800 pound tank of high pressure compressed air, that is distributed through reducing valves to 450 psi to power most of the onboard systems, which were all pneumatic / mechanical and required no electricity. The compressed air did four things: it ran the internal systems gyro, steering, pumps, guidance, etc, it fed the badder for buoyancy control, it fed the ignition system in that you can’t burn the fuel without air, and powered the startup system for the prop. The steam plant was mainly just for the propeller. When the torpedo is loaded in the tube and it is brought ready, the boat is supplying compressed air and warming steam to the torpedoes via a very precision machined contact plate. When it’s fired a mechanical pin both closes the valves and activates the burner ignition on the already pre-heated steam boiler on the way out the tube. For the first 1-2 seconds the torpedo is just running on the stored energy from the pre-warmer, but as it’s already up to temperature the boiler starts pretty close to instantly. The Mark 14 had a decent amount of flaws. It’s had issues with depth, tending to run deep. This specific gyro system also did not run true. It tended to process in a very large circle. It is believed, although not fully confirmed, that at least one submarine was sunk by its own circular running torpedo. Finally there were many flaws with the detonation triggers leading to occasional duds and pre-mature detonations. A lot of these problems weren’t completely corrected until more sophisticated systems with onboard redundancy could be built in the Cold War.Logic @ YT. Can a Torpedo Turn Around & Hit Its Submarine.
I love everybody admiring this creation for being masterfully crafted when in reality the MK.14 torpedo was one the worst-designed and produced torpedoes in all of human history. They didn’t test fire A SINGLE torpedo before mass-production and war started. They went twice as deep as they were set to, the magnetic detonator rarely worked, the impact pistol detonator broke off when it hit a ship before the mechanism could detonate the torpedo, they didn’t swim straight AND, possibly quite frequently, ran in a circle and hit their own ship. Multiple submarines were suspected to be lost as a result of this phenomenon and at least 1 incident was confirmed by survivors, the worst part about it was The Bureau of Naval Ordinance blamed the submariners for improperly maintaining the torpedoes, while not even distributing service manuals because they were considered “secret” even though it was a well-understood technology at the time worldwide. They REFUSED to address ANY of the problems and denied that ANYTHING was wrong with the torpedoes. Drachinifel has a good video on it. Zak@YT. The Mark 14 Torpedo Scandal of 1941-43.
