(only known picture of it on the internet, it is mounted on a F-4D in the picture)

i would like to suggest the XAIM-4H (also known as the AIM-4H) for the F-4E phantom II and F-106a (and F-4D if it is ever implemented)

History

The falcon missile family started in 1951 with the GAR-1(AIM-4A) a SARH guided missile, with multiple variants following soon after the: the AIM-4B an ir guided missile, the AIM-4C an improved pylon capable AIM-4B, AIM-4E a SARH missile, AIM-4F/G “super” falcon both were extended versions of the falcon with improved seekers (the F being radar and the G being ir), and finally the AIM-4D which was a recycled AIM-4C with the improved seeker of the AIM-4G made for anti-fighter use

The XAIM-4H was a prototype missile based on the AIM-4D-8(the extended cooling variant of the AIM-4D). It was made to correct the shortcomings of the AIM-4D(and the D-8) in Vietnam. Such shortcomings as the lack of a proximity fuse , the lack of capabilities in anti-fighter combat and the fact that the pilot had a difficult time firing the missile due to the amount of switches needing to be switched.

There were only 25 missiles ever made. It was developed from 1969 to 1971, in the Santa Barbara Research Center (SBRC) by the Hughes Aircraft Company with Program Manager Deniz Claud E and Head of SBRC Robert Talley on a 15 million dollar contract.

It was tested in Eglin Air Force Base and at Edwards Air Force base by Plans and Requirements Deputy Chief of Staff Robert T. Herres. There were 9 tests conducted with 4 hits and 5 misses. There were two confirmed tests on Qf-104s at Eglin AFB( 55-2969 and 56-747 nicknamed ”Queenie” ) in all successful tests the fuse worked properly. A few missiles were loaded onto a f-106a of the 318th FIS during William Tell 70 at Tyndall AFB.

It was canned in 1971 due to budgetary reasons by a committee due to the fact that they saw the XAIM-4H as unnecessary since they had already modified the AIM-4D in the form of the AIM-4D-8.
However, the laser proximity fuse of the XAIM-4H did not go to waste as the proximity fuse was later modified for use in the AIM-9L and later variants of the sidewinder as the DSU-15a/b under contract N00123—73—C—0256.

Characteristics
The main features of the XAIM-4H was the laser proximity fuse, the gate width IRCCRM and the larger warhead and is otherwise the same (the g pull, length, wingspan, fin aoa, diameter are the same).

  • WIng Span: 20in (50.8cm)

  • Length: 79.2in (201.168cm)

  • Diameter: 6.4in (16.256cm)

  • Thiokol M58A2 Solid Rocket Motor

  • Laser proximity fuse (the two dots at the back of the missile in the photo)

  • Gate width IRCCRM

  • Weight: exact weight unknown; confirmed to exceed AIM-4D baseline weight

    Spoiler

    All i know is that it definitely did not weigh 160lb as that figure is pulled from Bill Gunstone’s An
    illustrated guide to modern airborne missiles which contains incorrect information on
    the missile (the book confuses the laser proximity fuse as Active Laser Homing, and bases the stats such as weight, wingspan and diameter on the AIM-4F/G super falcon)

  • Larger warhead

Notes:

  • In game visually the only difference would be the texture
  • The weight would depend on how heavy you make the warhead and improved electronics (as the proximity fuse should be weigh something close to 9lb)
  • The missile was probably all-aspect since the better electronics and the fact that the seeker on the AIM-4D(and AIM-4G since they shared the same seeker) was semi-all-aspect already
  • If you’re wondering about the performance in game, imagine a slightly slower AIM-9J that’s all aspect and has Gatewidth IRCCRM

This has my support since it would make the addition of F-4D very justified.

Gaijin should do a second look at early missiles / low production & prototypes as there just as interesting as any aircraft. Though they may just be a painful unlock or a good enough starter missile there all nice to see.

Admittedly there’s very little information about this missile available, but conversely most of it’s stats can be referenced from the very well known aim-4d/rb-28 so it shouldn’t be too difficult to implement.

The main advantage of this missile is that it (and it’s distant japanese relative, the aam-2) can be placed as an upgrade option to the aim-4d/aim-4g on planes that carried it; as it has a proximity fuse, it can be used as a stopgap solution until the guidance issues with contact fused missiles in warthunder are fixed. It clears up the way for the F-4C/D in the american tech tree and the F-4 EJ in the japanese tree. And if the F-106A is too oppressive at 9.3 BR, you can justify a br increase by giving it access to the aim-26b and xaim-4h.

so was the motor of this missile improved in any way compared to the falcons we currently have in the f106?

thats the one thing i do not understand
