The Squadron's Mosquitos
Apart from two Avro Lancasters used for H2S MkVI training for Tiger Force, the squadron used
only the De Havilland Mosquito which was, in the unbiased opinion of the squadron members,
the finest aircraft ever produced. Despite what you might read elsewhere, the Squadron never
had any Douglas Bostons!

Mosquito B Mk IV DZ601 AZ-A of 627 Squadron
The Mosquito was, like all of the RAF's best aircraft, designed as a private venture and initially
attracted little interest from the Air Ministry. It was originally designed as a light bomber
with enough power to outrun enemy fighters, making defensive armament unnecessary. Another
unusual feature was that it was built entirely of wood instead of the valuable aluminium and
alloys used in most aircraft. It soon became one of the RAF's most versatile aircraft, excelling
in roles as diverse as photographic reconnaisance, anti-shipping strike, night
fighter and, of course, its intended purpose as a bomber. 7,781 were produced between 1941 and
1950 in Britain, Canada and Australia, the last remaining in RAF service until 1955. Only a
small number of Mosquitos survive, none of them airworthy.
All of 627 Squadron's Mosquitos were bomber versions, and carried the code AZ. None survives
complete, but various fragments and parts exist in several museums and at crash sites in Britain
and abroad. A full list of the Squadron's aircraft can be found in At First Sight.
