Perhaps the Mossie VI can get its long range fuel tank in the bomb bay option added as well.
I can count the number of time I loaded more than 50% fuel on the VI on the fingers of one hand. The VI gets 17 minutes per 25% at MIL power, so 100% is 68 minutes. That is without the small or the huge DTs available.
A more interesting option would be the 25lbs AP rockets in a two-pairs structure that allows a DT at the same time. The DT will still be an overkill, but the rockets allow another weapon type that leaves less drag than the fixed rails we have now. If the 25lbs AP rockets could also be modeled to travel underwater and puncture ship hulls below the water line for extra damage - now that would be something!
I see the historical point of having the option available, but in AH I've not ever come across a bombing run in which I've needed the extra fuel. If I take the 6/500 lb bombs the Mossi climbs even faster and gets to the target that much faster, and if I take the cookie I usually add wing tanks depending on the alt I'm going to reach.
The VI is the fighter-bomber version, not the unarmed bomber. It typically needs even less fuel than the bomber for its missions.
