That functionality was added back into FotRSU a while back, but I can't remember when / which version... The "load-out" for them will eventiually be more restrictively controlled by date before too long, and in conjunction with different torpedo load-outs, might be able to offer another level of "reality" with some of the missions during the early & mid war periods, even though it will involve a "cobbled together" paradigm... The idea will have to be strictly date-controlled, and from what we've seen, the game, entirely too often, runs over attempts at restricting certain aspects of the game by date, so the idea we have may not come to fruition...

We'll see. In the meantime, the availability of decoys is not as restrictive as in real life, though the amount might be somewhat low for late war missions. More research is needed for such...
