TP arming Min range ?

[AP514]

Hey all my first mission and using TWOs..I found my self in the middle of 2 DD's and a old dreadnought... was to close get firing solution and to close to dive. So figured What the HELL going for a Point blank shot. 2 dd's are right out in front of my bow about bearing 40 to my Starboard and 150m out crossing my front. the other is trailing 1/2 ship length about 400 meters out. I figured the speed earlier at 16 knots.. now I want to just do a fast fire straight ahead.

I clicked (X) on the closest DD locked him in and set my scope to zero..AOB to around 80 Port and range to 30 meters. I set 2 TP's to 3 meter depth med speed. 1 to 4 meters and slow with magnetic.

fired 1st TP before closest DD got into screen(scope at Zero degrees) It ran past closest dd and hit and sink the DD.

fired the electric set to MAG then the other shortly after...both hit closest DD
BUT, on the Tac map just showed TP bounce off hull then continue along.

Is there a min set distance needed for TP to arm ?
Is there a way to make it live in the tube ?

Also am I doing some thing wrong on my quick fire set-up ?



Thanks in advance
