HMS Eagle was an early

China Station
, spending very little time in home waters other than for periodic refits.

Eagle spent the first nine months of World War II in the

commerce raiders. During the early part of the war, the Fleet Air Arm was desperately short of fighters and Eagle was equipped solely with Fairey Swordfish torpedo bombers until late 1940. She was transferred to the Mediterranean in May 1940, where she escorted convoys to Malta and Greece and attacked Italian shipping, naval units and bases in the Eastern Mediterranean. The ship also participated in the Battle of Calabria
in July but her aircraft failed to score any hits when they attempted to torpedo Italian cruisers during the battle. Whenever Eagle was not at sea, her aircraft were disembarked and used ashore.

The ship was relieved by a more modern carrier in March 1941 and ordered to hunt for

South Atlantic. Her aircraft sank a German blockade runner and disabled a German oil tanker in mid-1941 but did not find any other Axis ships before the ship was ordered home for a refit in October. After completing an extensive refit in early 1942, the ship made trips delivering fighter aircraft to Malta to boost its air defences in the first half of 1942. The German submarine U-73 torpedoed and sank Eagle on 11 August 1942 as Eagle was escorting a convoy to Malta during Operation Pedestal
.

Design and description

Construction and conversion

In 1911, the

super-dreadnought battleship, with an option for a second ship, each to be armed with ten 14-inch (356 mm) and sixteen six-inch (152 mm) guns, that were named Almirante Latorre and Almirante Cochrane.[1] Almirante Latorre was laid down in December 1911, followed by Almirante Cochrane at the Armstrong yards at Newcastle upon Tyne on 20 February 1913. On the outbreak of the First World War, construction of the two ships was suspended. The British Admiralty purchased the almost-complete Almirante Latorre, which then in 1915 entered service as HMS Canada. At the outbreak of war, Almirante Cochrane was almost complete up to the forecastle, although her side armour had not yet been installed. No further work was carried out during the war until the British decided to complete her as an aircraft carrier for the Royal Navy. They purchased her from Chile on 28 February 1918 to be converted into the carrier HMS Eagle.[2] She was the fourteenth ship of the Royal Navy to bear that name.[3]

The

petrol storage consisted of 15,000 imperial gallons (68,000 L; 18,000 US gal) in 2-imperial-gallon (9.1 L; 2.4 US gal) tins stowed on the forecastle deck and protected by 1-inch (25 mm) plating. Two ready-use tanks near the islands would allow aircraft on the flight deck to refuel. The ship's planned armament consisted of nine 6-inch guns and four 4-inch (102 mm) anti-aircraft guns mounted on the platform between the islands.[4] Eagle retained the battleship's mixture of coal and fuel oil, but the quantities were increased to 3,200 long tons (3,300 t) of coal and 1,750 long tons (1,780 t) of oil, as the forward and rear 14-inch magazines and shell rooms were converted to be used as oil tanks.[5]

Based on trials with

fire-control directors for the armament. At the request of Admiral David Beatty, commander of the Grand Fleet, the main armament was increased to 12 six-inch guns, including one mounted on the island, and eighteen torpedo tubes were added, three triple fixed mounts on each broadside, in case the ship met German light cruisers at night. The anti-aircraft armament was reduced to a single 4-inch gun mounted on the island between the funnels as Beatty believed that the ship's own fighters would be her best defence against enemy aircraft. This design was approved in June, although work had begun earlier.[6]

The 4.5-inch (114 mm) armour planned for her upper

fitting-out ten days later. The boiler uptakes were re-routed and the existing openings were plated over. The existing 1.5-inch (38 mm) upper deck became the floor of the hangar deck and a new superstructure was built above it. The flight deck was 1 inch (25 mm) thick and served as the uppermost strength deck, or main supporting deck, of the ship. When the war ended in November 1918, the ship was about nine months from completion.[5]

Construction was slowed by industrial action after the war, and was suspended on 21 October 1919 as Chile wanted to repurchase the ship and have it re-converted to a battleship.[8] The £2.5 million cost of doing so would have been higher than the £1.5 million offered by the Chileans and the Admiralty decided to retain the ship. The Royal Navy needed to carry out flying trials with a carrier fitted with an island, and the Admiralty approved the use of Eagle on 11 November. Armstrong Whitworth plated over the openings for the undelivered lifts on the flight deck that had been cancelled when they could not meet the specifications. Armstrong Whitworth also finished the rear funnel, removed the torpedo tubes, and plated over the forward funnel uptakes. She then sailed to the Royal dockyard at Portsmouth for the modifications necessary for the trials on 20 April 1920.[8][9] Only two of her boilers, converted to run on fuel oil only, could be used during the trials.[10]

Flight trials

Eagle during trials

The trials principally tested the longitudinal arresting gear used previously on the small aircraft carrier Argus.[11] They were not intended to stop landing aircraft—the landing speeds of the time were low enough that this was unnecessary given a good headwind—but rather to prevent aircraft from veering off to one side and falling off the flight deck.[12] Initially, the arresting gear was about 170 feet (51.8 m) long and was installed too far forward. Over the course of the trials it was moved further to the rear and lengthened to a total of 320 feet (97.5 m).[13]

The ship was commanded during the trials by

shock absorbers to handle the impact of landing on a pitching deck.[14] Group Captain Samson strongly preferred the elimination of the island entirely, but Nicholson recommended that the ship be retained for service, although he was not satisfied with the size and shape of the island.[11] He also recommended that Eagle be converted to burn fuel oil exclusively and that the removal of the 6-inch guns in exchange for anti-aircraft guns would allow the tripod mast in the island to be eliminated, since it would not then be required for fire control purposes .[15]

Description

The ship was

paid off on 16 November, but did not begin construction to a revised design until 24 March 1921 at Portsmouth. The Admiralty accepted some of Nicholson's suggestions, but not all. The shape and size of the island was modified in accordance with the results from wind tunnel testing at the National Physical Laboratory, but the 6-inch guns were retained. The forward edge of the flight deck was faired into the ship's bow to smooth out the air currents over the bow and the 4-inch anti-aircraft guns were mounted on and around the island. The forward lift was moved to the forward end of the hangar. After construction began, anti-torpedo bulges were added, 6 feet (1.8 m) deep, and the petrol tin storage room was replaced by a 8,100-imperial-gallon (37,000 L; 9,700 US gal) tank. The ship's designed fuel capacity was 3,000 long tons (3,000 t), but this was increased to 3,750 long tons (3,810 t) when she was bulged. However, 500 long tons (510 t) of this amount was required to act as ballast to offset the weight of the island and its equipment.[16]

Eagle had an

standard load. Each of the ship's four sets of Brown-Curtis geared steam turbines drove one 3-bladed propeller.[17] They were powered by 32 Yarrow small-tube boilers. During her sea trials on 9–10 September 1923, the turbines produced 52,100 shaft horsepower (38,900 kW) and gave Eagle a speed of 24.37 knots (45.13 km/h; 28.04 mph), but this caused leaks in the turbine joints and she was limited to a maximum of 50,000 shaft horsepower (37,000 kW) in service. She had a range of 4,800 nautical miles (8,900 km; 5,500 mi) at 16 knots (30 km/h; 18 mph).[18]

The ship's flight deck was 652 feet (198.7 m) long and her

fire curtains to isolate any fires in the hangar. The forward lift's dimensions were 46 by 47 feet (14.0 m × 14.3 m) and the aft lift was 46 by 33 feet (14.0 m × 10.1 m). The fore-and-aft arresting gear was 328 feet (100.0 m) long and extended the length of the flight deck between the edges of the lifts.[19] A large crane with a 60-foot (18.3 m) radius was positioned behind the island.[5] The ship's aircraft capacity was 25 to 30 and, in 1939, the ship's crew totalled 41 officers and 750 men, exclusive of the air group.[20]

For self-defence against enemy warships, Eagle had nine

QF Mk V 4-inch AA guns were positioned on the flight deck in front of the island while a third was behind the island. The remaining two guns were mounted on top of the island, one between the two funnels, and each gun was provided with 150 rounds.[17]

Career

Inter-war

Aerial view of Eagle in 1931, prior to her refit

Eagle was assigned to the Mediterranean Fleet on 7 June 1924 after she commissioned on 26 February and finished

working up. She was the largest aircraft carrier in the world at the time and embarked 24 aircraft in four six-aircraft flights of the Fleet Air Arm of the Royal Air Force. These consisted of No. 402 Flight with Fairey Flycatchers, No. 422 Flight with Blackburn Blackburn reconnaissance aircraft, No. 440 Flight (Supermarine Seagull flying boats) and No. 460 Flight with Blackburn Dart torpedo bombers.[21]

While in the Mediterranean, one flight usually operated ashore at either

QF 2-pounder pom-pom light anti-aircraft guns were added forward of the 4-inch guns on the flight deck in front of the island and the ship's petrol capacity was increased to 14,190 imperial gallons (64,500 L; 17,040 US gal).[21]

When the ship returned to the Mediterranean after the completion of her refit in 1926, the Bisons of

Dornier Do J Wal ("Whale") Numancia was forced down due to fuel exhaustion on the first leg of an attempt to fly westward around the world.[22]

When Eagle returned to the Mediterranean later in the year, both 440 and 448 Flights had re-equipped with Fairey IIIF reconnaissance aircraft. Eagle departed Malta on 8 January 1931, en route to Portsmouth to load the latest carrier aircraft for a demonstration at the British Industries Exhibition at Buenos Aires, Argentina. She returned to the Mediterranean to participate in the summer fleet exercises before sailing for Devonport where she began a lengthy refit in August.[23]

The ship's boilers were replaced during the refit and the 4-inch gun between the funnels was replaced by an eight-barrel QF 2-pounder Mark V pom-pom mount. A single quadruple

High Angle Control System (HACS) director was fitted on the aft end of the control top on the tripod mast. The crew, now numbering 753 sailors and 253 airmen, benefited from improved accommodation. The refit was completed on 28 November 1932, but personnel shortages prevented her from working up until April 1933.[24]

Following the refit, Eagle was sent to the Far East, serving on the China Station throughout 1934, with her aircraft being deployed against

Hawker Osprey fighters of 803 Squadron and 12 Fairey IIIFs of 824 Squadron; the latter unit was re-designated as 825 Squadron in October 1934. 803 Squadron transferred to HMS Hermes when she relieved Eagle at the end of 1934.[25] They were replaced by Blackburn Baffin torpedo bombers of 812 Squadron when Eagle arrived in the Mediterranean in February 1935. Both squadrons remained behind at RAF Hal Far when the ship sailed for Devonport for another refit in June.[27][28]

Eagle was paid off until her refit began in early 1936.[28] Transverse arresting gear was installed and a second octuple pom-pom replaced the 2-pounders in front of the island. Two more quadruple .50 machine gun mounts were installed in sponsons on either side of the bow. The capacity of her bomb magazines was also increased during this refit,[26] and the ship's ventilation and insulation arrangements were improved as well. She was sent back to the Far East in 1937 with only nine Fairey Swordfish torpedo bombers (cloth-covered biplanes) of 813 Squadron aboard[29] as well as nine more Swordfish to re-equip 824 Squadron when it transferred from Hermes in April.[30] Captain Clement Moody commanded Eagle from 1 January 1937 until relieved by Captain A. R. M. Bridge on 16 June 1939. In August 1939 the ship's crew was exchanged in Hong Kong and Eagle sailed for Singapore to begin a short refit on 12 August.[31]

World War II

1939–1941

When World War Two began the following month, the ship had just completed her refit in Singapore. She put to sea a few days later and began searching for German merchant ships in company with the

commerce raiders. In mid-December her boilers and bottom were cleaned during a period of maintenance in Durban, South Africa.[32]

Eagle in Alexandria harbour, December 1940

Eagle continued to patrol the Indian Ocean in 1940, but escorted a large Australian troop convoy to Suez early in the year. While in the vicinity of the Nicobar Islands on 14 March, a 250 lb (110 kg) bomb accidentally exploded, killing 14 men. The damage to the ship was mostly confined to the bomb magazines, although two generators were knocked out. The explosion flashed upwards through the port bomb lift and ignited the wing on one Swordfish stowed in the hangar. All but four of the aircraft were damaged by the corrosive salt-water spray system when the fire was doused. She was repaired at Singapore between 15 March and 9 May when the ship sailed for Colombo en route to the Mediterranean, which she reached on 26 May. In June three crated Gloster Sea Gladiators were found in storage at Dekheila and these aircraft became the only fighters available for the entire fleet in the Eastern Mediterranean.[33]

Flying from shore bases on 5 July, 813 Squadron attacked

Savoia-Marchetti SM.79 medium bomber was shot down on 29 July by Eagle's Sea Gladiators while attacking the fleet.[41]

On 22 August three Swordfish from 824 Squadron, flying from Sidi Barrani, attacked and sank the

manned torpedoes to attack British shipping in Alexandria harbour.[42] In September, she was joined by the carrier Illustrious and both ships attacked Italian airbases on Rhodes on 9 September. Eagle's 12 Swordfish were late in taking off and attacked the airfield at Maritza after the Italians had been alerted by the earlier attack by Illustrious' aircraft on the nearby airbase at Collato. Four aircraft were shot down by the defending Fiat CR.32 and Fiat CR.42 Falco fighters, but two SM.79s were destroyed on the ground and four other aircraft were damaged.[43] These losses were the ship's heaviest in any single mission of the war.[44]

While covering another convoy to Malta on 12 October, she was damaged by near misses from SM.79s based in

mines.[47] On 28 October, Eagle and the rest of the Mediterranean Fleet patrolled off the west coast of Greece for a few days hoping to intercept the Italian Navy if it supported the Italian Army in their invasion of Greece, but no contact was made.[48]

When the ship was examined on 5 November, her aviation fuel system was leaking and required repairs. Five of her aircraft were transferred to Illustrious for an attack on 11 November on Taranto (Operation Judgement), whilst Eagle remained in Alexandria. One of Eagle's Swordfish was shot down by the intense Italian anti-aircraft fire. The ship covered multiple convoys to Greece and Malta during the rest of November.[49] Six of her aircraft bombed Tripoli harbour during the night of 24/25 November without loss.[50] Eagle spent most of December in Alexandria, but her aircraft supported the ground war, most notably when they spotted for the battleships Warspite and Barham during the bombardment of Bardia on 2 January 1941. In mid-January, the ship covered a convoy to Greece, but bad weather foiled plans to attack Italian bases en route. After her return, her aircraft complement was reorganised to include more fighters, as Eagle now had sole responsibility for fighter cover over the fleet after the crippling of Illustrious by German dive bombers on 11 January. In order to make room for the fighters, one of the Swordfish squadrons was disembarked and used to support the ground war. When Eagle was covering another convoy to Malta in mid-February, the ship carried nine Fairey Fulmars of 805 Squadron, five Sea Gladiators and six Swordfish.[51]

After the carrier Formidable arrived on 9 March to relieve Illustrious, orders were cancelled that would have transferred Eagle to the South Atlantic to hunt for German commerce raiders and the ship did not leave Alexandria until 9 April.[52] In the meantime, both Swordfish squadrons were transferred to Port Sudan to operate against Italian shipping in Massawa, in Italian East Africa, on 25 March. They were very successful and returned to the ship on 13 April after she had passed through the Suez Canal.[53] After she reached Mombasa, Kenya, on 26 April, she was ordered to sea on 29 April on an unsuccessful search for a raider in the Indian Ocean. The ship was then ordered on 1 May to proceed to Durban, South Africa, to rendezvous with the battleship Nelson and to proceed to Gibraltar. After the two ships arrived in Freetown, Sierra Leone, on 25 May to refuel, Nelson was ordered to continue to Gibraltar, but Eagle's orders changed and she was now charged with hunting for German supply ships in the South Atlantic. Captain A. R. M. Bridge was relieved by E. G. H. Rushbrooke at this time.[54]

Eagle began searching the South Atlantic on 29 May, usually accompanied by Dorsetshire or the light cruiser Dunedin. The carrier's Swordfish discovered, bombed and sank the blockade runner Elbe on 6 June. The oil tanker Lothringen was captured on 15 June by Dunedin after it had been bombed and strafed by several Swordfish. The ship continued patrolling without incident except for a hangar fire that killed one aircraft mechanic on 20 September. All but four of the ship's Swordfish were damaged by the spray used to put out the fire, but the ship herself was undamaged.[55]

In October 1941, Eagle was ordered to return to Britain for a refit at Gladstone Dock, Liverpool. She arrived off Greenock on 26 October and was docked at Liverpool on 1 November.[56] The quadruple .50 machine guns were replaced by 12 manually operated automatic 20 mm Oerlikon light anti-aircraft guns, six in sponsons on each side of the flight deck, and the crews of the four-inch AA guns were given protection from splinters by the addition of zarebas around each weapon. The HACS was moved to the front of the control top and fitted with a Type 285 gunnery radar. A Type 290 air warning radar was also installed. The ship's oil fuel capacity was reduced to 2,990 long tons (3,040 t) in exchange for an increase in her petrol storage of 3,000 imperial gallons (14,000 L; 3,600 US gal). This reduced her range to 2,780 nautical miles (5,150 km; 3,200 mi) at a speed of 17.5 knots (32.4 km/h; 20.1 mph).[57]

Eagle's refit was completed on 9 January 1942 and she was working up for the next five weeks. She joined the convoy WS16 en route to Gibraltar on 16 February and reached it a week later. 813 and 824 Squadrons had rejoined the ship with their Swordfish and they were supplemented by four Sea Hurricane 1B fighters from a detachment of 804 Squadron and the Fighter Flight of 813 Squadron.[58][59] Because their wings could not fold, they could not use either lift and remained on the flight deck at all times. The ship reached Gibraltar on 23 February and was assigned to Force H.[60]

Battle of Malta

HMS Eagle and HMS Malaya, from HMS Argus serving with Force H in the Mediterranean, 7 March 1942

Upon Eagle's arrival in Gibraltar, 824 Squadron transferred to RAF North Front and the ship loaded 15 Supermarine Spitfire fighters brought to Gibraltar by the carrier Argus.[61][62] These aircraft were partly assembled dockside and hoisted aboard for final assembly. They were too big to fit below deck and remained on the flight deck, where they impeded the operations of Eagle's aircraft, except for those few also carried on the flight deck, until the ferried aircraft were flown off.[63] On 27 February 1942, she sailed to deliver the Spitfires to Malta, escorted by the battleship Malaya, Argus, the cruiser Hermione, and nine destroyers, but the operation had to be cancelled when the long-range fuel tanks of the Spitfires proved defective. The problems were not rectified until 7 March, when the 15 Spitfires were successfully flown off to Malta. Upon her return, the ship's engines required repairs that lasted until 13 March.[64] Nine more Spitfires were delivered to Malta on 21 March and an additional seven on 29 March.[65] After her return, her steering gear required extensive repairs that lasted until the end of April.[66]

Eagle listing to port and sinking, 11 August 1942

As part of Operation Bowery, Eagle rendezvoused on the night of 7/8 May with the American carrier USS Wasp, carrying 47 Spitfires, while Eagle had landed her entire aircraft complement to make room for 17 Spitfires of her own. Sixty of them arrived safely at Malta. For the next operation on 17 May, the Swordfish and Sea Hurricanes of 813 Squadron flew back on board to join the 17 Spitfires and six Fairey Albacore torpedo bombers destined for Malta. The fighters flew off without incident, but engine problems forced all of the Albacores to return.[67] After they had landed, the ship was attacked by a half-dozen SM.79 torpedo bombers which failed to score any hits. The radar-guided guns of the escorting light cruiser, HMS Charybdis, were instrumental in driving off the determined Italian aircraft.[68]

Eagle disembarked all of her aircraft, except for her four Sea Hurricanes, to make room for 31 Spitfires and flew them off on 3 June during

Operation Pinpoint). During this time, the carrier's aircraft complement consisted solely of six Sea Hurricanes of 801 Squadron. Another 29 Spitfires as well as four Swordfish of 824 Squadron were loaded on 20 July and the Spitfires were flown off the following day.[71] Earlier in the day, the ship was unsuccessfully attacked by the Italian submarine Dandolo.[72]
