McDonnell Model 156

MAC Model 156_1 MAC Model 156_2 MAC Model 156_3 In 1971 and 1972, I worked as a Polysonic Wind Tunnel (PSWT) test conductor for McDonnell Douglas in St. Louis. In the small front lobby outside the tunnel control room was a display model of the McDonnell 156. Other than these pictures, which I took, I can find no other info. It appears to me as a proposed entry into the 1960’s Tactical Fighter Experimental (TFX) requirements ultimately resulting in the F-111. Anyone have any further info?

Yep, this was the McDonnell design for the TFX program. This model seems to be the earlier Air Force design with side-by-side seating.

Please find more pics and info on this and other TFX designs on my web forum here:,526.msg131222.html#msg131222

Also has a string family resemblance to the earliest Model 199 studies for FX which can be found here:,15610.msg152593.html#msg152593

Paul -

Thanks for this info!
It does seem to be the McDonnell US Navy TFX competitor of General Dynamics F-111

I don't suppose you have any more mysterious models you need identifying?
