Next Gen IR missiles are probably going to be added just like ARH missiles, in other words, every nation will get their equivalents at the same time. Which means just like how the AAM-4 is nerfed right now to be added. All those IR missiles will probably be nerfed and added (probably just not immune to chaff, so current IRCCM but better kinetic performance).
I also just don’t see them buffing it ever. The current game is balanced around being able to counter each other’s weapons and tactics. I don’t think they’ll ever add IR missiles that can’t be flared off even if that’s how they were IRL. Maybe with ECM, but since we don’t have those mechanics yet, it’s hard to say.
I’m actually wondering if Australia will integrate Spikes on their AH-64Es as well. I did read Australian pilots doing the initial training on the AH-64E in the US were also learning the Spike weapons system. But I don’t know if Australia plans on using them.
Yeah, it’s being integrated on the U.S. AH-64E Guardians until another system is developed. Israel does have it on its AH-64D’s though. Just note this missile isn’t the same as those (Spike ER) found on the Tiger or AH-60. They’re the Spike NLOS, a larger missile with significantly longer ranges and capabilities. I believe its listed range is 32km but could be higher.
