Should large mines be counted as three mines for sweepers?

[Aussie Gamer]

I have put anti-engine on a minehead it seem to work!
Can't see why the components would not work, except as pointed out during those threads, the mines will keep going off if there is an enemy ship in the square. So if you load um up with anti-engine/ anti-weapon they will all go off as the ship is still alive.
But they would make for excellant bobby-traps and also for those empire who use boarding parties!!! No engines- No supplies before fight- no shields/ weapons
