Martinsyde G.100 / G.102 Elephant

  FIGHTER, BOMBER, RECONNAISSANCE AIRCRAFTVirtual Aircraft Museum / United Kingdom / Martinsyde  


An unusually large aircraft by contemporary standards for a single-seater, the Elephant two-bay equi-span staggered biplane was designed by A A Fletcher of the Martinsyde Company, a prototype powered by a 120hp Austro-Daimler engine entering test in the autumn of 1915. The initial production version, the G.100, was powered by a 120hp six-cylinder Beardmore engine and was armed with a single 7.7rnm Lewis gun mounted above the centre section (this later being augmented by a similar weapon bracket-mounted to port behind the cockpit), deliveries to the RFC commencing in 1916. The G.100 was succeeded by the G.102 version which differed in having a 160hp Beardmore engine and replaced the lower-powered model progressively.

The G.100 and G.102 Elephants were used in France and the Middle East, although only one RFC squadron was completely equipped with this type, a total of 270 being manufactured. While not particularly successful as a fighter owing to its poor agility by comparison with its smaller contemporaries, the Elephant performed a useful service as a bomber, carrying up to 104kg.

I have a copy of an ink drawing of a Martinsyde G100 or 102 with an inscription on the tail 4871. The drawing is signed with the initials G.W dated 23 /4 /18. He produced this drawing whhile in the Fairfield hospital. Would it be possible to have the name of the pilot. Thank you

Re the railway story . I belive this is true and think it was in the Dardenells or the middle east. I will research and get back to you

67 Sqn RFC were said to have made a prop driven railway car from an old "Elephant" front fuselage and used it to patrol rail lines.Is this true and if so do photos survive.
Most consensus is that this story is a hoax.Please advise

Martinsyde Attack on 16th November 1916 by 27 Squadron

In bitter weather on 16th Capt Sherrin led Six Martinsydes over 90miles to drop eight 112-lb bombs on the railway station at Hirson from just 1,000feet. Six coaches were blown off the tracks and buildings and other rolling stock were destroyed.

Info I found from The Martinsyde File by Ray Sanger
This book has a very detailed account of all Martinsydes ever flown

I have a prop stock (now a clock) with the following written on it: Avro 120 120hp Daimler Beardmore Martinsyde Biplane. The are 3 other marks including a war office arrow. Does anyone know if this is from a G102 Elephant bomber? If not what?
