High temperature magnets for motors (controlling flight surfaces), radar, sonar, lasers. TLDR miniturization, increase power draw. Might have to reduce range due to heaver components, or keep range by deliver smaller payloads, all while sensing less because you can't power emitters as hard, i.e. now you're using more ordnance to attack/defend. But main issue is if you can't smuggle, designing around is expensive / long process and all of a sudden your inventory has 2 supply chains for new / legacy fleet.
