Vought V-433 Close Support

[Mark Nankivil]

Hi All -

Another scan from the Vought Archives. The date on the 3 view drawing appears to be July, 1957 so I am not too sure what specific Navy program this was proposed for or if it was an unsolicited proposal. Nice looking design nonetheless.

Enjoy the Day! Mark

According to the Vought Design List it was intended for the Navy (Marines ?)

 

[robunos]

any idea as to the engine proposed??


cheers,
Robin.

It shows T56 turboprop on the plan.

 

[Mark Nankivil]

There's no obvious tailhook on the drawing so I was thinking USMC as well.

Enjoy the Day! Mark

Oh, yes, I see it now... :-[


cheers,

Look again at the assembly sequence drawing, there appears to be a hook shown with Lower Aft Item 610.

You're quite right Jon - thanks! Mark

Its got to be related to the TS 149 (A-6 Intruder) studies Vought did, they included a single engined turboprop design. TS 149 designs were submitted in August 1957 which is closely contemporary.

TS 149 required twin seats and advanced avionics however - but it was designed to meet both a Navy long range interdiction and a Marine Corps close air support mission.

Perhaps this design was a study of filling just the Marines CAS mission without the long range interdiction role?

 

[Mark Nankivil]

That makes a lot of sense - the two roles seem to be rather contradictory for one airframe, especially if you view close air support by the USMC definition vs. what the USAF (and maybe to some extent, the US Navy) thinks it means. The Harrier proves that.

Enjoy the Day! Mark

The hook is there...see the image below.

Model photos, artwork and drawings can be found in American Secret Projects: Bombers, Attack and Anti-Submarine Aircraft along with details. It was an unsolicited study from 1959 for a low cost Navy attack aircraft. The engine was initially a T64, then T56.

From the Vought Archives a model of the V-433 and an artists concept.

Here are a few more images of V-433 models from the workshop of Jay Frank Dial who did some of the modeling for Vought. The image with the P-39 and V-433 are an interesting size comparison

Thanks @Bill S. I don’t know why, but it reminds me a little of the Breguet 960 Vultur. Must be the turboprop and similar mission requirement (Naval close air support)…

…and interesting to note the jet exhaust in the wing. This makes me idly wonder if Vought too looked into mixed propulsion, with a small jet engine to improve combat performance? Or if the giant T56 in the nose was tweaked to produce more residual jet thrust than the typical turboprop?

Dang that looks like it would have been a blast to fly!

Jay Frank Dial was a friend of deceased forum member Gary Morelock ("elider") and Gary photographed several Vought project models in Dial's possession.

Had one in the collection and thought it was Douglas. What threw me was the light blue canopy and an exact match to my many Douglas in-house wood models. You can see him here - he is hiding on the 4th shelf down, middle.
