Admiralty Air Department Navyplane

The A.D. Navyplane was designed by Harold Bolas as a two seat pusher floatplane.

Two were ordered in January 1916 for the Royal Naval Air Service and serial numbers were allocated for seven (9095-9096, N.1070-N.1074) but only one prototype was completed (9095).

It was originally fitted with an American Smith Static ten cylinder single-row engine, and flight tested in August 1916 by Lt.Cdr John Seddon. The engine was later replaced by an AR.1 rotary (later redesignated BR.1 for Bentley Rotary 1) and retested in May 1917. The performance was found to be poor and the aircraft was oficially deleted on 27 August 1917.
