HMS Lookout was an L-class destroyer of the Royal Navy. She was launched on 4 November 1940 and broken up in 1948. She was one of only two L-class destroyers to survive the Second World War, the other being .
Ordered under the 1937 Programme, Scotts Shipbuilding and Engineering Company were awarded the contract to build her. She would be the second Royal Navy ship to bear the name Lookout. Build was completed on 30 January 1942 and the tender cost was £440,204 which excluded items such as weapons and communications equipment supplied by the Admiralty.
After a successful Warship Week National Savings campaign in January 1942, HMS Lookout was adopted by the civil community of Burnley, Lancashire.
Operational history
Sea Trials
Lookouts sea trials were generally satisfactory, but were rather protracted through no fault of the ship. On 18 January 1942 Lookout underwent her gunnery trials which were entirely satisfactory. Gun mountings 'B' and 'X' lost two cartridge cases overboard when firing abeam, but this did not affect the outcome of the trial. The next day Lookout carried out her preliminary full power trial at a mean displacement of 2,320 tons. Her first attempt at a four-hour full-power trial was carried out on 21 January 1942 but was abandoned due to bad weather conditions. Her next attempt at the trial was a success. On 20 January Lookout finally carried out the trial in a Force 6 wind. Her mean displacement was 2,625 tons with a mean power of 48,442 SHP, giving a mean speed of .
Arctic Convoys
Lookout was with the Home Fleet in March 1942 when the German battleship made ineffective attempts to intercept Arctic convoys (Operation Sportpalast). One of Lookouts first operations took place on 4–7 March, when she was part escort to a battle squadron which included , and . The battle squadron sailed to cover against any move by Tirpitz to intercept Russian convoys QP8 and PQ12. Tirpitz was out at sea during this time but failed to locate the convoys due to bad weather conditions. A straggler from PQ12 was however sunk by , a destroyer who was screening Tirpitz.
Operation Ironclad
Lookout participated in the allied occupation of Madagascar. She joined her sister ships and at Durban on 22 April 1942 and they departed on 28 April 1942, en route for Diego Suarez (now Antsiranana), with invasion transports and escort. On 7 May the three L-class destroyers escorted the battleship to search for an enemy battleship and cruisers. None were found, but Laforey sank an enemy submarine.
Operation Pedestal
In August 1942, Lookout was escorting the aircraft carrier when Eagle was torpedoed on 11 August and sunk. Lookout carried out an unsuccessful counterattack with and then helped rescue the 927 survivors. Lookout later transferred 500 of the survivors to . The next day Lookout joined in an attack on an enemy submarine which they had sighted on the surface, but no kill was made. Lookout was then detached with Charybdis, and Lightning to assist the aircraft carrier after she had been hit by dive bombers.
Shortly after Operation Pedestal, Lt.Cdr. Cecil Powis Frobisher Brown relinquished command of Lookout and was relieved by Lt.Cdr. Archibald George Forman. He was later promoted to commander while in command of Lookout.
During her second patrol after Operation Pedestal, Lookout encountered a merchant ship which was identified as , an Italian vessel of about 4,000 tons. Lookout went to action stations but the vessel was found to have been abandoned and so a skeleton crew was put on board to examine her. Eventually the stokers managed to raise steam on her and Lookout escorted Luarana to Gibraltar.
Having spent much of August and most of September 1942 operating out of Gibraltar, Lookout returned home as escort to the battleship , departing from Gibraltar on 30 September and arriving on the Clyde on 5 October before departing the next day for Rosyth where she arrived on 8 October. She then sailed north to Scapa Flow, arriving there on 9 October.
Lookout then left Scapa Flow on 23 October for Gibraltar as part escort to battleship , arriving on 29 October at which time she rejoined the 19th Destroyer Flotilla.
Operation Retribution
In May 1943 Lookout took part in Operation Retribution and sailed from Bone with and the hunts of the 57 Division, departing on 9 May. On their way up the swept channel they were bombed by Ju 88s, but suffered no damage. The next morning the ships sighted the Italian hospital ship Virgiglio and was ordered to escort her to waters of Cape Carthage to examine her. The boarding party later reported that everything was as it should be and the Italian ship was released.
