That less than 1/3rd kill ratio. Good odds for the Kaleuns

The statistics are a bit confused because they often combine kills for single and double Squid installations - the double fit (as it was always intended) was much more deadly. The converging pressure wave concept, designed to crush the U-boat's hull, is shown below:



That actually shows Limbo I think, but the principle and depth bombs used were exactly the same. And even 1/3rd odds doesn't sound good to me!

Didn't one of the early escorts accidentally launch a Squid round into her foc'sle by mistake? Something to do with mixing up practise and live charges?
