While at the begining of the 1950's the engine technology was developed at a rapid rate at the US with engines as J57 J75 J79 in france it was the opposite . The French Aviation industry was frozen and non exsist during WW2. Company named Atar was starting to develop Jet engines based on the Jumo 004 of the German Me 262. Altough the Atar was much better then the Jumo it was not comparable with the British Avon or JE and Pratt and witney counterparts.
France was called in the 1950's the land of Prototypes with a good reason for that - nany planes some with briliant performance completed test flying programs witout funds for building them.
In order to overcome the engines problem a method of Hybrid plane that will a rocket engine for high performance together with two small Jets for landing and take off was developed.
The Trident could achieve 80k feet
and fly at a speed approaching mach 2.0 !!!
The Starfighter recieved the J79 and could reached mach 2.2 with this engine !!!
Both were able to climb very fast to intercept a bomber with Sidewinder or Matra 511 missiles.
The two even confronted in the German air force early competition stages which the F-104 won ( by bribing high ranking german officers and politicians )
The two are from WHM in a scale of 1:48.
