Chief Engineer's Report U-330
Patrol #2

Duration:     24.11.1939 - 28.11.1939, 5 days on sea

I believe the Kommandant has discussed the new ASDIC sound to you. I feel that the Allies have developed a new style of ASDIC which can now pinpoint our depth, as well as direction and range. Additionally, their wasserbomben are now able to sink to 150 meters before detonating. This is a big step, since we were always able to dive deep and remain well below them. This, along with the new ASDIC sound presents a whole new problem for us. Please check into a type of ASDIC called the “147”. I have heard a bit about this at the “Scheherazade” in Paris and until now was no more than mere speculation.

We are still having problems with our torpedoes. I feel that they are running much too deep and we seem to have a high failure rate for those with the Pi-2 pistols which are set to “magnetic” detonation. Please forward this to those in charge for greater review.

Also, I am aware that our Chief Mechanic, O. Masch. Harry Jaschinski, seems to have little regard for the proper operating temperature of the diesel engines. I have seen the temps on the exhaust manifolds reaching very high critical parameters on the last two patrols and have spoken to him several times regarding this; evidently to no avail.

This has also been brought to the attention of our Kommandant Oblt. S.M. Grabowski, who has had several talks with Jaschinski, but with little effect on his operating practices. He suggested we look at his operating practices on the next patrol, after a pre-patrol talk and take greater action, should the need arise. I am convinced to try this.

All other systems seemed to function well. No cooling problems on the diesels, despite running flank several times for hours on end.
