INDEX OF NAVAL
Ex Rio Hudson
HMS Avenger and the "Avenger" Class ships were basically similar to the "Archer" Class, but differed sufficiently to be regarded as a separate class. All were converted in the USA from mercantile hulls. When Avenger and Biter first arrived in the UK they went immediately into dockyard hands to have their flight-decks lengthened by 42 feet to allow Swordfish aircraft to take off with a full load of weapons and fuel. A fourth ship, Charger, was retained in the US after completion and used for training Royal Navy Fleet Air Arm pilots.
Avenger's war service commenced on 3 September, when she left Scapa Flow on her first official active duty, as an escort to convoy PQ18 to the north of Russia. She was equipped with 12 Sea Hurricanes from 883 Squadron, and 3 Swordfish from 825 Squadron.Convoy PQ-18 to Russia in September 1942, where her aircraft sank the German submarine U589 on 14 September with the assistance of the destroyer HMS Faulknor.
She arrived back in Scapa Flow on 3 October after a very active first operation. Her Swordfish had flown 32 sorties and attacked 6 of the 16 U-Boats sited, while the Hurricanes had destroyed and damaged 26 aircraft in 31 combats during 59 sorties. They had engaged German U-Boats, flying boats, Junkers Ju88 bombers and Heinkel He111 bombers. In all 13 merchant ships were lost, but the convoy claimed 42 German aircraft destroyed.
In her second operation, Avenger was ordered to take part in Operation
"Torch", the invasion of North Africa. She left the Clyde on 22 October
with her sister-ship Biter and the Fleet Carrier Victorious, to join the
slow assault convoy KMS1.On 7 November, Avenger left the convoy and sailed
to join HMS Argus off Algiers. From here,
the combined ships' 30 Sea Hurricanes and Seafires would provide fighter cover for landings planned for dawn on 8 November. No airborne opposition was encountered on 8 or 9 November and the Vichy French in Algiers surrendered earlier than expected. The Royal Air Force assumed responsibility for air defence, and with her aircraft ashore, Avenger was excused from duties. On 10 November she entered Algiers harbour to undertake repairs to problems with her engines, which had reduced her maximum speed to only 14 knots.
After taking part in the Operation Torch landings of North Africa in
November 1942, she departed Gibraltar with convoy MFK 1(Y) on 14 November,
heading home to the Clyde in the UK. The Convoy consisted of HM ships Almaak,
Argus, Avenger, Dempo, Etterick, Letitia, Macharda, Orbita, Samuel Chase,
and Ulster Monarch. At 0305 on 15 November, Avenger was torpedoed by the
German U-Boat U-155, along with two other escorting merchant ships, Ettrick
which sank, and Almaak, which was damaged. Avenger was hit on the port
side amidships, which in turn ignited her bomb room, blowing out the centre
section of the ship. Her bow and stern sections rose in the air and sunk
within 2 minutes, leaving only 12 survivors.
HMS Avenger was torpedoed and sunk west of Gibraltar by U-155 on 15 November 1942. The wreck is located in the North Atlantic, 45nm S of Cape Santa Maria, Portugal.
