HMS Hermes (R12)

HMS Hermes (R12) was a Royal Navy Centaur-class aircraft carrier laid down for service during the late World War II era that entered active service in 1959 and later became the flagship of the Royal Navy during the Falklands War while serving as flagship of the British Task Force before being sold to the Indian Navy and recommissioned as INS Viraat. Designed as a fixed-wing carrier later adapted for jets and helicopter operations, she bridged post-war carrier development from Royal Naval Air Service traditions to modern carrier aviation and power projection.

Design and construction

Hermes originated from wartime exigencies in the late Second World War shipbuilding program managed by the Admiralty (United Kingdom) and ordered as part of the 1942 Design Light Fleet Carrier expansions. Built by Vickers-Armstrongs at Barrow-in-Furness, her hull reflected the evolution from Illustrious-class aircraft carrier wartime designs, incorporating an angled flight deck influenced by trials on HMS Triumph and HMS Eagle (R05). The ship’s island superstructure, steam turbine machinery from John Brown & Company patterns, and armored flight deck retained elements of Battle of the Atlantic-era survivability doctrines while accommodating jet operations developed during the Cold War (1947–1991). Delays in post-war austerity, changing aircraft requirements such as the Supermarine Scimitar and Fairey Delta 2, and budgetary cuts affected completion. Launched in 1953, she was completed and commissioned in 1959 after modifications to the arrestor gear and catapult systems to operate contemporary jets like the de Havilland Sea Vixen and Fairey Gannet.

Operational history

Upon commissioning Hermes joined the Home Fleet and later rotated through deployments with the Mediterranean Fleet, Far East Fleet, and Atlantic Fleet. She participated in high-profile diplomatic and operational events including port visits to Cape Town, Singapore, Hong Kong, and Gibraltar, projecting British influence in the era of decolonization and Cold War geopolitics. Hermes underwent several major exercises with NATO partners such as Exercise Mainbrace and bilateral operations with the United States Navy carrier groups, integrating carrier air operations with Sea King and Whirlwind helicopters for anti-submarine warfare alongside fixed-wing squadrons. During crises such as the Suez Crisis aftermath and regional tensions in South Asia, Hermes served as a flexible response asset. In 1982, as tensions between Argentina and the United Kingdom culminated in the Falklands War, Hermes was hastily fitted with Sea Harrier fighters and electronics, becoming the flagship of the British task force commanded by Admiral Sir John Fieldhouse and later Rear Admiral John Woodward, and played a crucial role in air defense, maritime patrols, and amphibious support during the campaign.

Aircraft and air group

Hermes’s air group evolved from piston and early jet types to V/STOL and helicopter complements. Early squadrons embarked Fairey Gannet ASW aircraft, Hawker Sea Hawk fighters, and de Havilland Sea Vixen interceptors. By the early 1980s, modernization enabled operation of the BAe Sea Harrier FRS.1 V/STOL fighters and Westland Sea King anti-submarine and search-and-rescue helicopters drawn from Fleet Air Arm squadrons such as 800, 801, and 820 NAS. The carrier also launched AgustaWestland Lynx helicopters in later Indian service. Embarked air groups specialized in air interception using Blue Fox radar, maritime strike with Harrier-compatible ordnance, airborne early warning trials with observers, and shipborne anti-submarine warfare integrating sonobuoys and dipping sonar from helicopters.

Modifications and refits

Hermes underwent phased modifications to keep pace with changing aviation and threat environments. Early refits incorporated an angled flight deck and steam catapult enhancements influenced by ASW lessons from the Atlantic Gap and NATO requirements. Mid-life refits improved radar and electronic warfare suites, replacing legacy radars with newer types sourced from Marconi and upgrading communications compatible with NATO datalinks. In 1976–1980 refits, hanger modifications, reinforced deck sections, and ski-jump trials were conducted to evaluate V/STOL operations that presaged her conversion to operate Sea Harrier jets during the 1982 conflict. Boilers and turbines received overhauls at Devonport Dockyard and Rosyth Dockyard, and aviation fuel systems were upgraded to NATO standards. Upon sale to the Indian Navy, further refits at Vickers and Mazagon Dock adapted the carrier for extended service with tropicalization, modernized fire-control systems, and embarked Indian aircraft types.

Decommissioning and fate

The Royal Navy decommissioned Hermes in July 1984 as part of post-Falklands force restructuring and defence reviews including the 1981 Defence Review. She was sold to the Indian Navy in 1986, recommissioned as INS Viraat, and served as flagship for decades, participating in exercises such as Operation Jupiter and regional deployments in the Indian Ocean. Viraat was finally decommissioned by the Indian Navy in 2017. After attempts to preserve her as a museum ship failed amid financial and logistical disputes involving stakeholders including Andhra Pradesh and Kerala interests, she was sold for scrap and towed for dismantling, concluding the long operational life that began with this Royal Navy carrier’s post-war service.
