Any info on the XAIM-4H

Hello, I am wondering if anyone has any information on the XAIM-4H (like an SMC)
all i know is that it was tested against QF-104A target drones and that it has a proximity fuse

all info i have found on the missile :https://ausairpower.net/Falcon-Evolution.htm

Hello there. Unfortunately, the XAIM-4H series remains the most elusive variant of the Falcon missile. All I’ve been able to find out about it is second-hand mentions that it was derived from the aim-4d, that it had a laser proximity fuze, and that seeker had an early form of IRCCM but beyond that nothing; No SMC, no test footage or even pictures.

The only aim-4 variants that are confirmed to have proxy fuses are the radar guided AIM-26a/b, and the IR guided, japanese developed, AAM-2.

But if you find anything about the XAIM-4H feel free to post it on the thread dedicated to the falcon missile family.

There is an image of the seeker somewhere from a guy who just, owns it personally IIRC? Its a very basic quad segment design, but technically that does mean it has full gatewidth IRCCM by WT standards.

Although, given the base seekers performance, it would still be fairly flareable. Only really being resistant likely within 1km range rear aspect only.

I’m going to also post this here:

do you remember where? couldn’t find it in reverse image search

Ive found some other stuff
Robert Talley – SBRC-SBRS History
tldr: the XAIM-4H had a larger warhead with 9 tests performed(4 hits 5 misses) and better electronics.
A variant of the the proximity fuse was then made for the aim-9(probably the DSU-15/B AOTD)

This is amazing, great work. You have singlehandedly increased the likelihood of XAIM-4H/AIM-4H being added to the game lol. Keep it up!
