FFAP-16 Mk I P-16.04 P-16 Mk II P-16 Mk III AFAAA-7 AJ-7 AR-7 |
Fifth P-16 (Mk III) |
In 1948 the Swiss Air Force tendered a requirement for a multi-role aircraft capable of short-takeoffs from runways situated in high mountain valleys. Prototypes were ordered from two Swiss firms, EFW and FFA. The Flug- und Fahrzeugwerke aircraft was known as the P-16, and was designed for interception and close support duties, and was selected over the competing EFW N.20 design.
Two Mk I prototypes were built. These were considered to be a bit underpowered, so four Mk II prototypes were ordered with a more powerful engine. After the loss of the first and third aircraft, the program was cancelled. FFA apparently held out hope for a production order, as the remaining two aircraft were completed to Mk III standard. A new company, Aktiengesellschaft für Flugzeugunternehmungen Altenrhein (AFA or AFU) was formed to continue development. Three re-engined variants, which also would have had slightly revised armament and electronics, were proposed: the AA-7, AJ-7 and AR-7, respectively with the SNECMA Atar 9C, General Electric J79 and Rolls-Royce RB.168. It was planned to modify the two Mk III prototypes, but no orders were forthcoming. The wing design, including the tip tanks, was later used as the basis for the Learjet business jet. At least one P-16 Mk III survives at the Fliegermuseum Altenrhein.
