I don’t think it is too much of a problem, especially if LEAPP continues to go well and delivers all the capability it promises. At that point, cueing the CAMMs won’t be a problem.
But i can agree that maintaining the possibility to use an IR seeker would have had its advantages.
However, the modular nature of CAMM does not rule it out at all: with CAMM expected to influence the future upgrades of the ASRAAM just as the current ASRAAM influenced the CAMM design, i guess an IR seeker will always be a feasible option.
What i really wish for is for a functional secondary surface-attack capability. That would be a major plus.
