Information

Developed to replace Japan’'s aging T-1 and T-33 fleets, as well as take on some of the duties of the T-2, the T-4 was designed to be cheap to operate, highly manueverable, reliable, and easy to handle.

Political imperatives dictated that the type use Japan’s first wholly indigenous turbofan engine, the Ishikawajima-Harima F4-IHI-30. This resulted in a twin engine design, both to generate adequate power, and as a safety factor, so that the aircraft would not be without power in the event that one of the fairly new and relatively untested engines failed. The engines output 16.37 kN (3,680 lbst) each, for a combined total of 32.74kN, or 7360lbf. Early problems with damage caused by excessive engine vibration have apparently been solved.

While some composite materials were used to save weight, most of the aircraft is constructed of aluminum alloys. At first glance, the aircraft appears similar in appearance to aircraft such as the Alpha Jet and the BAE Hawk - perhaps a symptom of convergent design. The aircraft makes use of a transonic airfoil for improved agility, in contrast with its competitors. While the aircraft has no internal weapons, it has 5 hard-points; one under the fuselage, and two on each wing.

While Kawasaki won the competition to design the T-4, production was a consortium effort, with parts manufactured by Mitsubishi, Fuji, IHI, and Kawasaki itself, with final assembly completed by Kawasaki. Production completed in 2003, with a total of 212 aircraft completed. In addition to serving as the JASDF’s intermediate jet trainer, the T-4 is used by Blue Impulse, the service’s aerobatics team, where it replaced the T-2 in 1995.

The Kawasaki T-4 is Japan’s current intermediate jet trainer.

Unfortunately, to our knowledge, the T-4 never carried any sort of armament, and is thus not eligible for addition to the game.

However...

thanks to the font of knowledge that is our moderator @leroyonly, I now know of two prototypes XT-4’s that carried gun-pods, 55-5602 & 66-5604.

These are readily identifiable as the same twin FN MAG gunpod carried by the Strikemaster. As such,

I can safely propose the gunpod armed XT-4 prototypes for addition to warthunder.

Wild Speculation on Armament

The T-4 has, to my knowledge, never carried any sort of armament beyond the gunpod used in its trials. It does, however, have three hardpoints, one centerline pylon, located under the fuselage, and one under each wing. The aircraft has been known to carry practice bombs, and practice IR missiles, but has probably never carried the real thing.

It is plausible that bombs were tested on such craft or at best plans for such but were not documented as it wasn’t necessary. Who really knows.

A +1 from me! Would be neat to have in the Japanese TT!

It’s probably the case of “If push comes to shove” it can mount those weapons in a combat role even if it’s just an intermediate trainer.

For specific loadouts for the XT-4 & the T-4 in general, i’d speculate that it would carry the following

  • Any dumb bomb that the T-4’s hardpoint carry limit allows
  • AIM-9’s (B’s & P’s) &/or AAM-1’s
  • FFAR Mighty Mouse and Zuni Rockets: Strangely enough the Fuji M-TX, the competitor of the XT-4 confirms this
  • ECM/Chaff pod: Unclear if it used flares alongside it
  • GCS-1 guided bombs: This one that may be stretching it though

Finally in the old forum it did mentioned the T-4 using a FCS in tandem with the F-2, not sure if it doubles as a ballistic computer though

My guess, based on HUD modes of the XT-4 would be that besides the gunpod or fuel tanks the loadouts would be:

  • Mk82 500lb bombs; Regular unguided and GCS-1 equipped guided variants. One carried on each hardpoint, total of 5.
  • JM117 750lb bombs; Regular unguided and GCS-1 equipped guided variants. One carried under the fuselage and on each inner wing hardpoint, total of 3.
  • FFAR Mighty Mouse rockets; Pods of 7 or 19 each. One carried on each wing hardboint, total of 76 (4×19)
  • FFAR Zuni rockets; Pods of 4 each. One carried on each wing hardpoint, total of 16 (4×4)

I don’t think there was any capability for air to air missiles or chaff, but I’d love to see anything to prove me wrong here.

Finding weapons data for the T-4 has proven to be very unproductive with pretty much the only confirmed sighting of stores being fuel tanks, target banners and the “Meteorological Collector Type 2” which is an air sampling pod that could easily be mistaken for a fuel tank at first glance.

Maybe a Japanese member can badger the JASDF with a freedom of information request (assuming it exists in Japan).

In the meantime here are a couple of pointers from the Kawasaki MT-X, the project that led to the T-4, that people may find interesting…

OMG YESSSSS PLEASE I’M GONNA MAKE LOVE TO THE SNAIL IF WE GET IT.

+1 suggestion, nice write-up. Can’t wait to see what other documents people post here

The flight international article says something similar about the three pylons, and it’d hardly be the first time an armed trainer was added to Warthunder. It wouldn’t even be the first time Japan got one. The main issue is that it’s immensely hard to find sources for claims that it ever did carry actual weapons. The closest I could get was an informational article from the 1987-1988 issue of Jane’s All the World’s Airplanes, which states:

The issue is that the first production T-4’s didn’t enter service until after that edition of Jane’s was published. Any information the writers would have gotten would have been from the prototype aircraft, and from Kawasaki’s initial MT-X2 proposal, which called for a very similar armament. We’ve only seen an XT-4 carry a gunpod, and assuming that the writers for Jane’s didn’t have access to classified information, it seems likely that they got this information from the MT-X2 proposal.

That being said, I don’t think it’d be outside the realm for plausibility for a defense analysis company like Jane’s to be privy to classified information. But that’s just my opinion.

In theory, this plane can carry gunpods, AAMs and bombs. It should do enough for a Rank 6 plane on the attacker line. Although it should be a cannon not 7.62s!
