HMS COURAGEOUS

HMS Courageous: First of the Modern Aircraft Carriers in World War II

HMS Courageous, a Royal Navy ship with origins in World War I, evolved from a battlecruiser to one of Britain’s earliest aircraft carriers. A brief World War II career during which it was sunk by a U-boat attack in September 1939 made it the first British warship, and carrier, to be lost in the conflict. "Serving in the Battle of the Atlantic, Courageous was to have been an important factor in the early stages of anti-submarine work, and to have typified the navy's switchover to the power of naval air. This report will examine the Shelton's design and special importance, as well as its key missions in World War II, namely the patrols and sinking, utilizing records to narrate its history.

Design of HMS Courageous

Origins and Conversion

HMS Courageous was launched on 5 February Originally designated as an enlarged version of the "Leader" class, the design was redeveloped as the first of a new class with the development of steam turbines for ships of the "Courageous" type. Commissioned in February 1916, it had a displacement of 19,500 tons and was 786 feet long with an eighty-one-foot beam. It was driven by miles of Yarrow boiler tubes and the propulsion of Parsons turbines, and rated at ninety thousand horsepower, giving it a top speed of thirty-two knots. She was initially armed with four fifteen-inch guns and 18 (4 inch) guns, and had light 3 inch belt armor in view of her speed.

Courageous was converted to an aircraft carrier between June 1924 at Devonport Dockyard and February 1928; this was in accordance with the terms of the 1922 Washington Naval Treaty. This involved removing the guns and superstructure and fitting a two-story hangar and a550-footwith two hydraulic catapults. A second, smaller "flying-off" deck permitted take-offs at lower speeds. Courageous had a complement of forty-eight aircraft, and could carry more aircraft than her half-sister Furious. The fifteen-inch turrets were ultimately mounted in HMS Vanguard.

Technical Specifications

Courageous, as an aircraft carrier, made arrangements for air operations and minimal self defence. Armament was composed of 16 x 4.7 inch (12 cm) AA guns, 3 x quadruple 2-pounder (40 mm) "pom-pom" mounts and 1 x quadruple 0.5 inch (12.7 mm) machine gun mount. The basic defense was provided by pom-poms, which had a range of five thousand yards, and machine guns, effective at eight hundred yards. Armor was thin, with a half-inch flight deck and steel bulkheads, making the ship vulnerable to torpedoes. Operationally, a Type 286 radar (range twenty-five to forty miles) and 1930 refit fire-control directors were carried. The 842 crew included personnel of the Fleet Air Arm, and the RAF, and Fairey Swordfish biplanes for anti-submarine duties.

Design Limitations

Courageous and its light armor became a death trap against torpedoes, as the speed at which it sank proved. Its anti-aircraft guns were antiquated and it proved ineffective against the type of aircraft it encountered, even though air strikes were not a consideration in its sinking. As long as it’s using escorts, however, it is vulnerable when screens disappear. The two-storey hangar, raised the center of gravity — resulting in unstable conditions, and the rudimentary radar and fire control technology did little to increase the effectiveness. These were short-comings that identified the Courageous as a "transition building" carrier.

What Made HMS Courageous Special

Pioneering Aircraft Carrier

Courageous was a first responder, a converted design bound by treaty regulations to fill the Navy’s need for carriers. Diverse missions, from reconnaissance to anti-submarine warfare, were performed thanks to its large hangar and high speed. Training carrier in the 1930s, and its squadrons (such as No. 801 (Blackburn Skua)) and No. 811 (Fairey Swordfish) were instrumental in helping to shape the tactics that saw active carrier operations that would come to dominate the world's oceans in the second half of the second world war. Its hydraulic catapults and MkIII arresting gear were to serve as templates for those used in all subsequent British aircraft carriers, such as the Illustrious and Implacable class.

Strategic Importance

Courageous was important to the anti-submarine campaign in the Battle of the Atlantic in 1939. Its Swordfish detected over a longer range in the Western Approaches where U-boats were menacing Allied shipping. This loss resulted in strategy changes, since carriers were removed from antisubmarine warfare (ASW) patrols in favour of convoy escorts and fleet operations, which proved their worth, provided that they were protected assets. The loss led to stricter escort procedures and the rapid development of anti-submarine technology.

Psychological Impact

The sinking was a propaganda triumph for Germany, and U-29’s crew received Iron Crosses. With Britain losing a major warship, the U-boat menace finally struck home, both to the Navy and to the British public. Admiral Karl Dönitz described it as “a wonderful success” that lifted German morale. The incident led to an overhauling of anti-submarine tactics that steered early war priorities.

Key Roles in Battles

The Battle of the Atlantic

Courageous’ main duty was to defend Allied supply lines in the Battle of the Atlantic. Recommissioned on 31 July 1939, it was assigned to the Home Fleet based at Portland with No. 811 and No. 822 Squadrons, each with twelve Swordfish for anti-submarine operations. Its patrols in close defense of the Western Approaches thwarted U-boat threats to Britain’s lifelines.

Early Patrols

Courageous was working out of Portsmouth by 31 August 1939, sailing on 31 August 1939 escorted by HMS Sturdy to her temporary base at Plymouth, by 2 September. As Britain declared war on 3 September, it began anti-submarine patrols together with the destroyers Acasta, Anthony, Amazon and Ardent. Together with HMS Eclipse, it examined an incorrect submarine reporting of it off Plymouth on 4 September. Patrols on 9 September with HMS Kempenfelt included Swordfish sweeps and no U-boats were attacked. These missions testified to Courageous’s potential, but she did not have the security of escorts.

Sinking by U-29

Courageous was patrolling 350 miles west of Land's End on 17 September 1939, together with the destroyers Iglefield, Ivanhoe, Impulsive and Intrepid. At 14:45, it answered a distress call from the merchant vessel Kafiristan, being shelled by U-53. Four Swordfish were flown off, and two escorts detached in pursuit of the submarine. One Swordfish compelled U-53 to dive, without causing any damage. At 18:00, when Courageous broached the wind to recover aircraft, she presented her beam to U-29, under the command of Otto Schuhart.

At 19:50, U-29 attacked the group firing three G7e torpedoes from a distance of twelve hundred metres. Two of them struck Courageous on the port side resulting in some serious internal flooding. The vessel went down in seventeen minutes at 50°10′N 14°45′W, 190 miles SW by S of Dursey Head, Ireland. 519 of 1,260 crew, including Makeig-Jones and 36 RAF personnel, were killed, as were all of the aircraft. They survivors were picked up by destroyers and merchantmen Collingsworth, Dido, and Veendam. The loss had brought the carrier based anti-submarine patrols to an end, with their vulnerability publicly exposed.

Contribution to Anti-Submarine Warfare

Courageous’s patrols prevented U-boats from freely operating on the surface. It helped to echo Kafiristan’s distress call, proving it could work in concert with air as well as surface assets, but its escorts had been pared down, leaving it vulnerable. The sinking also highlighted the requirement for stronger destroyer screens and separate anti-submarine vessels that influenced future tactics.

Challenges and Limitations

The light hull of the Courageous left it highly vulnerable to torpedoes and its quick sinking demonstrated this. Its anti-aircraft artillery was antiquated with negligible capacity to defend itself against modern aircraft; yet, in the end this was not a factor in its fate. Dependence on escorts, broken during the Kafiristan affair, was Achan's vital weakness. Damage control was complicated by the two-story hangar, and basic radar restricted the ability to detect incoming threats. All of these problems underscored the transitional nature of Courageous.

Legacy and Impact

The sinking of Courageous proved to be a turning point which convinced the Admiralty to withdraw carriers from anti-submarine patrols in favour of either convoy escort duty or fleet operations. Its training in the 1930s honed Fleet Air Arm tactics to be instrumental during later successes. The death of five hundred nineteen crew was a disaster, but the survivors’ tales helped develop better safety procedures. The battle led to anti-submarine innovations, like improved sonar and depth charges, that helped to secure Allied supply lines. Courageous’s short tour of duty foreshadowed the potential and pitfalls of naval aviation, shaping the war’s course of naval strategy.

final thoughts

And HMS Courageous was a revolutionary carrier whose short service in World War II set naval warfare on a new course. Unlike the previous two carriers, whose design was intended to be easily converted from a battleship to an aircraft carrier, Eagle had initially been designed as the battlecruiser Almirante Cochrane before it was decided to convert the unfinished vessel.The ship's high speed (34 kn) enabled it to take part in the vital anti-submarine warfare (ASW) patrols in the Battle of the Atlantic. Sunk by October 17, 1939, by U-29, it was the first early-war sinking of an aircraft carrier, and revealed the ship type's vulnerability, prompting strategic missions that featured escorts, which then led to the development of escort carriers. Courageous’ legacy is that of a pioneer, the lessons learned from its loss, and the heroism of her crew, ensuring its place in naval history.
