This was a British naval undertaking to deliver an updated air complement to the fleet carrier Ark Royal, escorted by the destroyers Faulknor and Fortune, of Vice Admiral Sir James Somerville’s Force ‘H’ (3 April 1941).
The aircraft were four Fairey Swordfish attack machines, fitted with air-to-surface vessel radar, of No. 825 Squadron and 10 Fairey Fulmar fighters of No. 807 Squadron. These aircraft were flown from the elderly fleet carrier Furious in exchange for four Swordfish and nine Blackburn Skua aircraft of No. 800 Squadron, which were flown off Ark Royal at the same time.
