Short SC-7 Skyvan


The Skyvan had its origins in the Miles Aerovan, the concept of which was taken on by Short in a radically overhauled design. It was designed to carry an 11-ton payload over 200 miles at 160 m.p.h, with an all-up weight of 8,600 lb.

Two prototypes were built at Belfast during 1960 with two 390-bhp Continental GTS IO-520s. It was decided that turboprop power was required, so the prototype and early production (Series 2) examples were ultimately fitted with Astazou II turboprops.

The Short Skyvan (G-ASCN), re-engined with Turbo-meca Astazou turboprops, flew for the first time with its new power plants on October 2, 1963. With Dennis Taylor at the controls the Skyvan was in the air for twenty-five minutes on its first flight.


These engines were not ideal for hot-and-high conditions or American customers, so the Series 3 was upgraded to the specified Garrett type.

The Skyliner was a dedicated passenger-carrying version.

The military version of the twin-turboprop Skyvan is the Skyvan 3M-200, which is cleared to an increased maximum take-off weight of 6,804kg for military operations. Powered by two 533kW Garrett TPE331 engines, the prototype Skyvan 3M first flew early in 1970. Troop transport, paradropping, assault transport, SAR, and medevac are among the capabilities of the Skyvan. The Skyvans of the Sultan of Oman’s Air Force have Racal ASR 360 airborne surveillance radars for maritime patrol and SAR duties.

The sole example of the Skyvan sold to the Sharjah Amiri Air Wing was delivered in 1986. It was also the last Skyvan built.

In all, 149 Skyvans were built and sold to commercial freight/passenger 'bush' operators and military/paramilitary operators up until 1986.
