12/31/2010. A private venture single-seat tactical support fighter, the S.E.5000 Baroudeur - a name derived from the Arabic word 'baroud' for battle, and, in French Foreign Legion parlance, describing a pugnacious fighter - was designed by Wsiewolod J. Jakimiuk. Of all-metal construction with a wing sweptback 36 deg at quarter-chord, the Baroudeur represented an attempt to achieve a measure of independence from permanent runways. In place of a conventional landing gear, it was provided with a combination of jettisonable take off trolley and landing skids à la Me 163 B Komet.

The first prototype was powered by a 5,280 lb (2,395 kg) st SNECMA Atar 101B turbojet and flew on August 1, 1953. Proposed armament comprised two 1.18 in (30 mm) or 1.46 in (37 mm) cannon. The Baroudeur was progressively re-engined with the Atar 101C and 101D-1, this last, rated at 5,732lb (2,600 kg) st, powering a second prototype, which flew on May 12, 1954 and featured a 3° increase in wing anhedral. Two months earlier, an official contract covered both S.E.5000 prototypes as well as three S.E.5003 pre-series aircraft.

The first S.E.5003 was flown in September 1955 with an 8,157 lb (3,700 kg) st Atar 101E-4, the second and third aircraft having a 6,283 lb (2,850 kg) st Atar 101D-3 and a 7,716 lb (3,500 kg) st Atar 101E-3 respectively. The Baroudeur eventually demonstrated the ability to take off without recourse to the jettisonable trolley and the first S.E.5003 was flown with flush-fitting auxiliary fuel tanks on the aft fuselage sides. The NATO nations elected to adopt a more conventional aircraft to meet the lightweight tactical fighter requirement and development of the Baroudeur was discontinued.
