The Republic F-105H Thunderchief design proposal

[Pioneer]

I found this on another Forum sight

In late 1962 or early 1963, Republic proposed the F-105H, with a new wing of 448 square feet, two seats, new landing gear, vertical fin, stabilator, new nose, etc. This was really a new design, and the USAF did not go for it.

They are looking for pictures or drawings of this proposed upgrade of the Thunderchief

Can you help?

In a Korean (  ) site I found only the following: the machine was a 1962 development of the F-105F with a new engine ( JT4B-24 ) . The site mentioned another project, the AP.63-19, that seems was a version proposed to Canada, France and UK as a standard heavy NATO fighter-bomber.

Wasn't the JT4 the J58?  Seems I've read of version of the F-106 (F-106X I believe), and the Crusader III also were considered for the J58.  And of course the Hustler.

(Nevermind.  Just checked it out and it's the J-75.  Anybody know anything about the JT4B-24 varient?  The article on the XF8U-3 Crusader III in an issue of Classic Wings mentions a couple versions, one at about 29,500lbs thrust and another at ~28,000lbs but doesn't give the designations.  In fact IIRC at least one of the three prototypes were powered by the 29k version.)

I think the JT4 is the civilian designation for the J75......I think there were PW plans for a turbofan version of the JT4, but it would have overlapped with their work they'd already done on the JT8D.

Pretty sure the J-58 was JT11.  I recall seeing the designation JT11D-2 associated with the Blackbird program before.

Uh, forgot, the Korean site (in Korean, so I use a translation via Babelfish...) says that the engine of the F-105H was rated at 30.000 lbs.

J-58 as fitted to the Blackbird family was, I believe, the JT11B-20.  P&W internal designations of that period had the "D" after the model number as a designator of a turbofan.  For instance, JT3B was the J75 while JT3D was the TF33 or the JT8B became the J52 but with a rework to the l-p compressor to make it a fan, you get the JT8D, originally done for a somewhat paniced Boeing on the original 727 when RR's intransignance almost killed the program.
