I'd love to read them, what are the titles?

But designed to run around and catch a DD mmmmm I dont think so.

Try reading "Submarines at War," by Edwin P. Hoyt. See what he says about circular torpedoes on page 268 ... maybe you're right (I no longer have the book available). Maybe I read that explanation somewhere else. I do know that O'Kane suspected (prior to more recent information) a circular run as the cause for Mush Morton's demise ... O'Kane, too, had something to say about the why and wherefore of such torpedo behavior.

Wait a minute, you dont have the book but remember the page number !

I took notes.

When SH3 first came out, I went to the library and checked out (and read) all the books on U-Boats. When SH4 came out, I did the same thing. Concurrently, I also read here, at the forum, a number of "assumptions" about what fleet boats could and could not do. Many of the assumptions were B.S. and, as the B.S. got to the point where guys were demanding changes to reflect their uninformed assumptions, I (and others ... RR, for example) started posting facts. Naturally, facts require proof. So I provided quotes from the books.

Unfortunately, some of the same assumptions came up time and time again. Along with the demands to change SH4. So, since the books belong to the library (and I don't care to go running back to the library and re-read a book every time I need a quote), I wrote down the page numbers.

Gotta love people who think they know more/better than you. I've had people "tell" me all about the navy and they never served a day in the military.

A great read is "Escape from the deep" about the Tang's last patrol. The Tang was the only sub in WW2 where many crew members actually escaped from a sunk sub in about 300 ft of water. Obvious a circle runner did the Tang in. The book goe's into details about how they escaped, how many died trying and others too scared or wounded waited for death as they watched others try to escape.

Also get's into detail about the survivors being captured and what they went through as POW.s.

From my understanding and reading circle runners were indeed real (no surprise there) but that long periods of time between tube flood and torpedo firing were causing corrosion that made them more likely to stick at full rudder when executing a gyro turn. I don't think a 0 angle shot could ever be a circle runner as it couldn't stick the rudder. I don't know if a very small gyro angle (1-10 deg or so) would ever command full rudder on the torpedo or if it would due to a "bang bang" steering type.

Improvements to the rudder posts (better grade of metal IIRC) as well as I think floodings much sooner to launch significantly reduced the problem.
