Whilst it did not fight in the Cold War, it did help to significantly upgrade the known torpedo technology knowledge base in the UK, Australia, New Zealand and the USA. The Horton Wing aircraft, 53.3 cm (21") G7a T1, Type XXI submarine (Elektroboote), Type 93 Long Lance Torpedo, V2 Rocket and V1 Rocket also had similar sort of technical upgrading influences in several countries to.

It's tech was used in thes subsEdit


U.S. Navy diagram of a Type XXI U-boat. Note the teardrop-shaped fairing for the large hydrophone array beneath the bow and the figure-eight pressure hull. The large sonar array and its housing did slow the boat down, but its placement and size allowed for a very sensitive system to be installed, and gave it near-360 degree coverage around the submarine.
