My son asked why they didn't move torpedoes from the front to the back, or the other way as needed. I explained that they're aimed in opposite directions and the problem of space not allowing to turn a torpedo around. And I added in the weight, lack of a good long straight shot. He then suggested that they could surface and do it that way. I got thinking and realized that theoretically, it was possible. In all the accounts that people have read, does anyone know of someone actually trying this?
