Thats pretty much the general assumption I had as well tbf. There just seema to be some oddities to it imo.
Structurally id assume the ASRAAM would outperform the IRIS-T in range/speed, but id also assume the CAMM-ER to outperform the SLM in that regard, which is allegedly not the case.
The CAMM-ER also adopts the strakes seen on the IRIS-T and its variants, and in general adopts more of an IRIS-T shape, also shared to some degree with the MICA.
CAMM-ER vs CAMM:
Then you have the fact that the IRIS-T is (allegedly) more expensive, AND more widely used than the ASRAAM, with effectively the only ASRAAM operator being the Brits (from what I can tell, india is one of those weird outlier nations that uses a bunch of different missiles in smaller numbers), while the IRIS-T is operated by multiple european and some asian countries.
Across the Eurofighter program, the IRIS-T is the selected missile by all nations but britain, and most recently the IRIS-T was selected for integration by the south koreans for the KFX (though idk if the ASRAAM competed?)
All in all, its a bit odd. There seems to be many claims about the ASRAAM’s superiority in both design and capabilties, particularly over the IRIS-T, but it doesnt seem to translate to real world use, with the CAMM-ER adopting the shape of the IRIS-T, and the IRIS-T being significantly more comercially successful.
This could be purely coincidence though, as missiles are chosen for more than just performance, so maybe the ASRAAM is the wonder weapon the brits claim it to be. I think it could also be argued that the ASRAAM is a bad MICA as well though, with the alleged goal of the missile being pre-merge interception, it kinda steps on the toes of BVRAAM’s, but also falls short in the range respect, while seemingly not having any clear notable advantages over the MICA IR in maneuvrability (both are over the shoulder capable).
The MICA is a larger missile though, which could limit how many are carried, but its also noteworthy in being a larger commercial success…
A little odd for such a fantastic missile to be the worst comercially performing 5th gen IR missile of Europe, which is why I think theres more to this than whats being claimed.
