Britain, Canada, and New Zealand used the Hampden.
The No. 49 Squadron first received the Hampden in August 1938.
By December 1938 the No 49, 50, and 83 Squadrons were equipped with the Hampden Mk I.
Start of War
There were eight (10) squadrons equipped with Hampden Mk Is at the start of World War II. They were with the No 44, 49, 50, 61, 83, 106, 144, and 185 Squadrons under the No 5 Bomber Group at Lincolnshire and Huntingdonshire.
Eventually fifteen squadrons would be equipped with Hampdens.
The first mission was on September 3, 1939, by the No 83 Squadron flying reconnaissance to Schillig Roads. Mission wasn't completed due to fog.
Early war missions involved dropping leaflets, mine laying, bombing invasion barges, and reconnaissance.
After it was shown how vulnerable the Hampden was in daylight they switched to night operations.
Hampdens were used in August 1940 / August 25 - 26, 1940 during the first raid on Berlin.
The No 144, 408, and 455 Squadrons, with Coastal Command, were equipped with the Hampden TB Mk I torpedo bombers.
On the night of September 14 - 15, 1942 was the Hampden's last raid. It was withdrawn from Bomber Command.
After being withdrawn from Bomber Command four Coastal Command squadrons were outfitted with the Hampden torpedo bomber.
Two of these squadrons, No 144 and No 255, were stationed near Murmansk.
Three squadrons used their Hampdens for weather reconnaissance.
