Ah the Concorde, typical French panache coupled with English stiff upper lip mentality but thanks to its thirsty nature and a change in views concerning environmental issues was doomed to have a very limited production and apart from the state airlines of the two countries who built her had no foreign operators. But what is lesser known was that she wasn't the only aircraft where the British and French shared their knowledge and created something beautiful. This is the round view of the Breguet Br. 121, a sleek powerful design that the French company submitted when the French Air Force issued an order for a replacement of their ageing fleet of Lockheed T-33, Fouga Magistere and Dassault Mystere VI ( A name that will later pop up again) jet trainers and light attack aircraft. At the same time the Royal Air Force issued their own order for a replacement for their Hawker Hunter and Folland Gnat trainers. In 1966 British Aircraft Corporation (BAC) and Breguet decided that it was in both companies' best interest to collaborate. Using the BR.121 as a starting point it was decided to spread the building of the compartments of the plane between both countries, this diagram showing what was going to be made where. The orange sections were to be built in France and the yellow sections in the UK with the engines coming from Rolls Royce. Naming their collaborative effort "SEPECAT" (Société Européenne de Production de l'Avion d'École de Combat et d'Appui Tactique – the "European company for the production of a combat trainer and tactical support aircraft) The redesigned Br. 121 would enter production under the name Jaguar and was accepted as the winner for the competitions in both countries. But one man, who was a big name in French aviation was not at all happy with that development. His name: Marcel Dassault Dassault had submitted his own design to that same competition and was facing a loss of a huge amount of money if his Mirage F-1 was rejected. Proving himself to be a very sore loser, Dassault decided that the only way to stop SEPECAT was to buy out the assets of Breguet, creating Dassault-Breguet. Solely for the purpose of making it impossible for the Jaguar to be built in series. But that plan was quickly stifled as the French Air Force reminded Dassault that with the Jaguar ordered and PAID FOR, breech of contract would cost him far more than just losing the competition. Dassault relented, Breguet would continue to built the Jaguar and because of him now being owner of the plant, he would get a good pay from it too, even though it still must have nagged him that he would be building that very plane that trumped him. The fact that when Dassault would have an official from an air force coming over to check the Jaguar out, he would offer the Mirage F-1 for a cheaper discount price shows just how much it nagged him. Regardless, the Jaguar went into service with both Armee De'l air and the RAF with the air forces of Ecuador, Nigeria and Oman, But by far the biggest operator of the Jaguar was India which also licence built the aircraft and is planning to keep them around for at least 20 years with update programs. Indian Jaguars over Alaskan skies during an exercise drill, the Indians will ensure that this plane will remain a familiar sight in the far east for a long time. The Jaguar still suffered from Dassault's meddling though, when the French Navy issued an order for a carrier based fighter jet, SEPECAT offered the Jaguar M (Marine, Navy) The Jaguar M differed from the normal land based variant in it having a stronger undercarriage, arrester hook and catapult fittings. But it never went into full scale production because Dassault offering the Super Etendard fighter instead. Japan also showed interest in the Jaguar but when licence building was proposed, Dassault raised the licence fee to such a degree that the Japanese lost interest and decided to build their own fighter instead. But it wasn't the victory that Dassault had hoped for because the resulting Mitsubishi F-1 and T-2 jets looked rather familiar... A very similar plane to the Jaguar, the F-1/T-2 series used the same Rolls Royce engines and the same fuselage design but the avionics were based on the Northrop T-38 Talon So there you have it, the SEPECAT Jaguar, that other plane aside from the concorde where the French and the British joined forces and suffered from in-fighting at one of the two factories where it was built. But even with Marcel Dassault's meddling the Jaguar had a good production run of a very respectable 543 built.
