In Operation Orator, during September 1942, 32 Hampdens of 144 Squadron and 455 Squadron RAAF were sent to Murmansk in Northern Russia in order to support the Arctic convoy PQ 18, and to attack any German warships that might sortie from bases in Norway against the convoy. The squadron lost 5 Hampdens on the flight to Russia, with a further four of 455 Squadron's also lost. The German surface warships did not attack PQ 18, and the squadron's personnel returned to Britain aboard a cruiser in October, leaving its aircraft behind to be handed over to the Soviets.
