Torpedoes used as mines?

[iron heart]

It will come up as an option on your next patrol, i have declined his idear every time. but i think the idear is like the LUT torps of the later part of the war were they run in a straight line so many 100's of yards then start to loop to the right so many 100 yards then loop left so many 100s yards till they hit somthing or run out of steam. if thats his idear i dont know ?.
