I’ll take a P-8 with LRASM. JDAM, not so much.
ISAR is a radar mode that is useful in the SUW mission.To the OP - new toys are good; more mission sets are typically disliked. We already do too many things with too few people/training hours. We currently are responsible in some fashion for ASW, ASUW, ISAR, Mine Warfare, SAR/HADR, and some other stuff I wont mention. Each of those takes a shit ton of time and effort to be come good at. The LRASM Brett mentioned would help with a current mission set. We don't need to slap an AMRAAM on the plane...
