History

After WW2, France was playing catch-up in aircraft development. In 1948, The Armée de l’Air created a specification for a low-flying ground attack aircraft, to replace its P47s and F6Fs. Sud-Est, or SNCASE, built off a design created right after the war, SE.2400. It was decided to create 2 prototypes, and later produce 360 planes. The plane was named Grognard, a nickname for Napoleon’s Old-Guard, but those working on it nicknamed it ‘hunchback’. It was first shown to the public at the 1949 Paris Air Show, though only as a scale model. On April 30, 1950, the first prototype, SE.2410 took flight. This plane had many problems, so while they were being fixed, work on the second, 2 seater prototype, SE.2415, commenced. This made its first flight on February 14, 1951. After both planes had their problems –which were mainly vibration issues at the tail–worked out, weapons testing commenced, notably the planes becoming the first French aircraft to fire an AAM, the Matra T10. During this, the Armée de l’Air overhauled its requirements for new planes. Instead of ground attack aircraft, it wanted all-weather fighter-bombers, and it eventually put into service the Vautour, also made by Sud-Est. The planes, judged to be inflexible in role, (the cockpit wasn’t pressurized, e.g.) and behind schedule, made the cancellation of the program well justified. Eventually, SE.2415 was badly damaged in a belly landing, and was used as a test target, while SE.2410 was shown at the 1953 Paris Air Show, but was hit by a bird strike and had to land. It was finally scrapped in 1954 after also being used as a target. Many more variants of the plane were drawn up, but were never built.

Design

The cockpit of the first design, SE.2410, was placed far forward, to give better visibility, and oddly had an old greenhouse canopy. However, the most interesting part of the cockpit was the elbow controls, which also gave the pilot more visibility. It was unpressurized and probably had an ejection seat, though other sources say otherwise. Behind the cockpit was the dorsal air intake for the two engines, as well as the large main fuel tank. The wings on SE.2410 were swept at an extreme 47 degree angle. This was done due to captured German documents and wind tunnel testing. The wings didn’t have a uniform profile, and were modular. The wings’ avionics were hydraulic, and they had leading-edge slats. Each wing later got two pylons. The weapon bay had a volume of 3 m³. The plane had a tricycle landing gear, with the same wheels as the Canberra, and they retracted backwards. This plane had the engines stacked on top of each other, like the English Electric Lightning. Originally, it was planned to house narrower engines, but after those hit development problems, it was decided to switch to Rolls Royce Nene 101s. These engines were so big and heavy, they couldn’t be fitted under the wings, nor side-by-side (the tail would’ve been too heavy), so they were fitted vertically. Benefits from this were that if one failed, the other would not create asymmetrical thrust, and it allowed for the large weapon bay. The horizontal stabilizer had a sweep of 35 degrees and was mounted very low, below the exhaust duct of the lower engine. This was so it wouldn’t be impacted by airflow from the rest of the plane. The plane was equipped with a drag chute, with a diameter of 4 meters.
