What if VJ-101C or its modified variants replaced F-4 and being adopted by Luftwaffe in ATL?

Guten Tag!

I really like the VJ-101C, it is like a German version of VTOL capable F-104G Starfighter clone without T-tail.

It seems to be promising with a lot of potential.

What will happen if it became a real operational military grade VTOL fighter jet instead of a short lived experimental aircraft in 1960s?

What modifications and armaments would it require to fit into Luftwaffe service, or even the Marineflieger?

Would it be practical to replace 4 of the RB.145 Engines attracting to its wings with 2 of the J79 Engines while making it truly Mach 2 capable?

Can it be armed with a 20mm M61A1 Vulcan cannon?

How could its developers do to overcome all the adversities that led to its OTL defunct in 1968 and keep the project survive?

I am not familiar with West Germany’s 1960s cold war history, so I would be grateful if you can work with me and help building the ATL of armed Luftwaffe VJ-101C fleet with your superior knowledge and prediction.

Danke!
 
The primary issue would be that the lift engines greatly cut into possible range of the aircraft in a combat mission.

Firstly by displacing fuel from the fuselage, and secondly by burning a lot of fuel during liftoff.

-------------------

Now, if we're strictly talking about the tilt-engine version, I'd strongly recommend against removing engines from the nacelles. Why? reliability in case of engine failure. If you have 2 engines each side, you might be able to recover if you lose one engine by chopping thrust on the side that still has both (this would likely have to be an automatic system to react fast enough).

If you only have 1 engine each side and lose that engine, you're absolutely losing that plane. Automatic ejection and you've got maybe 3 seconds to get clear to save the pilot.

Alright

I will keep the 6 engines and forget about the J79 engines, except these RB.145s would be replaced by the more proven J85 engines used by Bell D-188A and Northop F-5

I am waiting for the third or more commenters

Excellent illustrations!

In my opinion the VTOL technology of the sixties consumed excessive fuel at the expense of the payload, the VJ 101 would only have worked as an point-defense interceptor in a war of attrition in which all allied air bases had been contaminated with long-term chemical warfare. A desperate battle in which all the objectives worth defending would have already been hit by Soviet frontal aviation. In that type of warfare only an anti-tank aircraft would have been useful, but the armor would have further diminished the ability to carry bombs.

A dead end.
