The L.R.T.Tr., presumably signifying Long-Range Tractor
Triplane, was designed to meet an RFC requirement
for a combined escort fighter and airship interceptor.
Other contenders were the Armstrong Whitworth
F.K.6, also of triplane arrangement, and the Vickers
F.B.11, which was of more conventional biplane layout. Of bizarre appearance, the L.R.T.Tr. was a three-bay
triplane with narrow-chord wings, all of which were fitted
with ailerons. Power was provided by a 250hp
Rolls-Royce Mk I (Eagle I) 12-cylinder water-cooled
engine, and the crew comprised a pilot and two gunners.
One gunner occupied the rear cockpit and the
other a streamlined nacelle built around the upper
wing centre section, both having a single 7.7mm machine gun. By the time flight test commenced in
1916, it was appreciated that the concept of the
L.R.T.Tr. had been rendered outdated by the advent of
practical gun synchronisation equipment and the success
against airships enjoyed by more conventional aircraft.
This clumsy aeroplane, meanwhile assigned the
epithet of Egg Box, was duly abandoned.

The engine was probably a Falcon, not the Eagle.
