Cessna CE-550 Citation II / Bravo / T-47A
The success of the first Citation led Cessna to look at building larger and faster versions and development continued with the Model 550 Citation II. Announced in September 1976, the prototype first flew on 31 January 1977. Powered by two 1130kg JT15D-4 engines, the 8-12-seat aircraft featured a nearly 4 feet lengthened fuselage, increased span wings and more fuel and baggage space. Certification followed in March 1978.
In October 1983 the revised Citation S/ll was announced and the first production aircraft made its initial flight on 14 February 1984, with deliveries following soon after. This version has the JT15D-4B engine giving more power at higher altitudes, a new aerofoil section wing, leading-edge extensions, modified engine pylons and increased cabin headroom and baggage capacity. The Citation II/SP was cleared for single-pilot operation in July 1984.
A modified version of the Model 552 Citation S/ll was selected in May 1983 by the US Navy for training radar intercept operators designated T-47A. These have shorter span wings to increase rate of climb and maximum speed at altitude and more powerful 1315kg JT15D-5 engines. The T-47A first flew on 15 February 1984. Delivery of 15 T-47A was completed in May 1985. The T-47s are used to train aircrew in the operation of radar in both air-to-air and air-to-surface modes, and are equipped with nose-mounted Emerson APQ-159 radars. The US Customs Service operates seven Citations fitted with Westinghouse APG-66 (F-16A) radar. These are used to intercept and track drug smuggling aircraft.
The Citation II was taken out of production in 1984 when 503 had been built, but resumed in 1987. By the end of 1989 667 plus 15 T-47As had been delivered, making the Model 550 the best selling business jet.
The Citation II has now become Cessna Bravo.
