No. 423 Squadron
Badge A bald-headed eagle volant Motto Quaerimus et petimus (We ”
search and strike) ‘!.. Authority King George VI, March 1943
The bald-headed eagle is a powerful
bird of prey from the Canadian side
of the Atlantic. The motto refers to
the squadron’s role as a coastal unit.
Formed as a General Reconnaissance
unit at Ohan, Argyll, Scotland on 18
May 1942 as the RCAF’s 21st -sixth
and last coastal -squadron formed overseas, the unit flew Sunderland flying boats on convoy escort and anti-sub
marine patrols over the Atlantic shipping routes. When
hostilities ended in Europe, there was a need for more longrange transport units to support the proposed ‘Tiger Force” in the Pacific, and the squadron was redesignated
Transport on 5 June 1945 and began conversion training to Liberator aircraft. The sudden end of the war in the Far
East found the squadron still in the early stages of conversion training and it was disbanded on 4 September 194S.
