The AMX is an attack aircraft powered by a single 11,030-lb.-thrust Rolls-Royce Spey Mk 807 non-afterburning turbofan. Alenia and Aermacchi (then independent) initially pursued separate designs for Italy's attack/support requirement, but began collaborating in 1978. Embraer joined the program in 1980. The resulting single-seat aircraft made its maiden flight in 1984, with deliveries beginning in 1989. A two-seat trainer variant, the AMX-T, flew in 1990. Approximately 205 aircraft were built throughout the AMX production run, which ended in 2002.
Single- or two-seat, twin-engine air superiority fighter manufactured by Boeing, and license-produced by Mitsubishi. Most F-15 models built to date are powered by versions of the Pratt & Whitney F100 afterburning turbofan, but South Korea's F-15K and Singapore's F-15SG are powered by GE F110 turbofans, with Saudi Arabia using F110s in new and upgraded F-15SAs. The initial F-15A version first flew in 1972; deliveries began in 1974. The improved F-15C/D became the standard in 1979, but were superseded in the 1980s by the two-seat F-15E strike aircraft.
Schweizer Aircraft developed the Model 330 and 333 prior to the company's acquisition by Sikorsky in 2004. The 330 was developed from the company's piston-powered Model 300. The 330 and the improved 330SP models were both powered by a Rolls-Royce 250-C20W turboshaft derated to 232 shp. The uprated Model 333 (redesignated the S-333) offered a 100-lb. increase in useful load and a redesigned, larger-diameter rotor system. The new S-434 is an evolved S-333 using the dynamic components and four-blade rotor developed for the Northrop Grumman MQ-88 Fire Scout unmanned aircraft.
