The other problem with trying to clear wartime safety cases is categorizing the risk. You have to consider the effects of a range of weapons, with different lethality for varying modes of operation and delivery (assuming you can get this detail) on the weapon. The "safe route" would probably be to armour and over design everything, the end effect may be a flying tank or something that can outfly Janes book of weapons.
Alternatively, you lower the threshold to gain an acceptable design.
