Has there ever been a design or proposal for a three-engine jet fighter?

I think so , it was a german design in the 1960 before the F-4 was pushed onto them. But one of the engines was a rocket engine

The Yak-141 had three engines - a single lift/cruise engine plus two lift engines :D

As did the Yak-38 !!!!

Okay, I knew as soon as I posted it that someone would bring that up. :) To clarify, what I mean is three engines for forward thrust.

French Trident: 2 jets & 1 rocket.

Some British project might have contained 3 engines, too...

Are you looking specifically for a tri-jet? Or any fighter with more than two engines?

Germany's VJ 101c had four.

Yes, I'm looking for any instance of a fighter design or proposal with three engines mounted conventionally, i.e., intakes toward the front, nozzles in the rear. But it's starting to look like there haven't been any.

There was a proposed fighter version of the A-5 Vigilante with a third J-79 engine above the other two, and armament consisting of AIM-54 Phoenix air-to-air missiles, but it never got past the drawing board.

Scroll down toward the bottom of the page after clicking that link, and you'll find a drawing of it.....it was called NR-349.

There was Yugoslav Ikarus 452-3 experimental light interceptor. One model (452-2) was powered by 2 x Turbomeca Palas turbojets (150 Kg of thrust) and 452-3 with 3 x Turbomeca Palas .It was only armed with cannons (or even maybe with heavy machine guns) but I am not sure about calibre. Aircraft was tested during 1953 http://www.vj.yu/VOC/Grafika/Galerija/Avioni/452_1-znak.jpg

Funny - an old episode of BG is what caused me to think of the question.

Sorry I didn't notice this subject had been discussed before - I'm still relatively new to the board and haven't gone through all the archives yet.

Don't apologize for bringing up an old subject....especially since you're new.

If you want to learn you gotta ask, which is what you did.

Don't worry about it.

The MiG SM-50 (MiG-17 with a liquid rocket) came close, as would have the rocket-equipped Lightening (though since it was a double Scorpion, I guess that would have been four...).

The most insane three-engine fighter has to be the Polikarpov I-152/DM-2. A biplane with two ramjets. That's what comes of state-sponsored vodka !

Funny isn't it? This topic repeats itself here every once in 2-3 years and every time I hear/learn about a new tri-engined fighter! :)

Last time IIRC Arthur had posted a few tri-engine photos. I might have saved them - will look for them and post when and if I find them.

Phantom, the NR349 was to have its third J79 in the area occupied by the the bomb-and-fuel-tunnel in the A-5. It would have been a most remarkable aircraft...

Then there is the Curtiss XF-87 Blackhawk, a conventional four-engined jet fighter. The only kill it made was to the Curtiss company itself.

And the MiG SM-30 was a MiG-19 with the ventral fin replaced by a PRD-22 solid-fuel rocket, which qualifies as an engine if you ask me.

Me 262C

Some prototype and planned versions of the Messerschmitt 262 C had 3 engines - two jet engines and 1 rocket engine.
