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!

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.
