Short Stirling glider tugs

The Stirling

Designed by Mr. W. A. Gouge, designer of the Sunderland Flying Boat, and made by the famous firm of Short Bros., the Stirling was the first four-engined heavy bomber of the war to be produced in great numbers. It is a giant machine weighing slightly more than thirty tons, and each machine entails the making of over sixty thousand parts. It is now being produced on the line assembly principle at tremendous speed. Testing is carried out continuously during production, thus enabling the finished machine to be fuelled and taken into the air by the test pilot “almost before the paint has dried."

Stirlings have been known to be in operation over enemy territory forty-eight hours after leaving the factory, which speaks very highly of the skill put into the machine construction.

It is powered by four 1,375-h.p. air-cooled radial Bristol Hercules engine, and has a wing span of ninety-nine feet. It is considered the greatest weight-carrier in the world and, to give some idea of its immense size, the cockpit is twenty-two feet from the ground and the bomb traps forty-four feet long. It can carry six tons of bombs over a long distance (its full range has not been released), has a speed of about three hundred miles an hour, is highly manoeuvrable and can take endless punishment. It has been nicknamed by the R.A.F. the 'Turin Tourer' on account of one of its earliest flights being to Turin and back non-stop.

It is armed with ten .303 machine-guns, four in the nose, four in the tail and two amidships, and carries a crew of eight, who enjoy ample room and are all fitted with armour-plated chairs. It is most graceful in flight and has taken part in almost every big raid since its inception.
