HMS Hermes (95) was a Royal Navy aircraft carrier designed during World War I and completed in the interwar period. As an early purpose-built carrier, she served across Asia, Africa, and the Indian Ocean before being sunk by Imperial Japanese Navy aircraft in 1942. Hermes played a role in carrier development, regional power projection, and early naval aviation doctrine.

Design and construction

Hermes was laid down for Royal Navy requirements by Vickers-Armstrongs at Barrow-in-Furness after the Washington Naval Treaty environment and lessons from Battle of Jutland influenced design choices. She featured an early flush deck carrier layout with a full-length flight deck, island-less profile similar to experimental conversions such as HMS Argus, but with strength and speed derived from cruiser-type machinery like County-class cruiser plants. Her hangar arrangement, aircraft lifts and arresting arrangements reflected innovations from Admiralty committees and naval architects associated with John Brown & Company-era practice. Launched in 1924, she embodied interwar compromises between Imperial Defence commitments in China Station and the need to operate Fairey IIIF-type aircraft.

Service history

Hermes commissioned into the Royal Navy Mediterranean and later served on the China Station and with the East Indies Station. She supported Yangtze Patrol interests near Shanghai and conducted peacetime exercises with ships from HMS Hood-era battlefleets and Royal Australian Navy units. During Spanish Civil War tensions and Second Italo-Ethiopian War episodes, Hermes undertook fleet visits, showing the flag to protect British Empire trade routes through the Suez Canal and Straits of Malacca. Crews trained aboard alongside aviators from Fleet Air Arm squadrons transitioning from Hawker Osprey and Blackburn Ripon types to newer monoplanes.

Role in World War II

With the outbreak of World War II, Hermes operated in the Indian Ocean and escorted convoys between Freetown and Singapore, linking with forces like Force H and Eastern Fleet elements. She participated in Operation Menace-era convoy actions and patrols around Madagascar and the Bay of Bengal, interacting with HMS Exeter, HMS Ajax, and HMS Achilles on multinational deployments. After Japanese advances following the Attack on Pearl Harbor and Indian Ocean raid, Hermes was stationed to cover retreating Allied merchant traffic and support Malayan Campaign defenses. During Singapore Campaign developments, she evacuated personnel and attempted to interdict Japanese invasion convoys until overwhelmed by carrier-borne Aichi D3A "Val" and Mitsubishi A6M Zero attacks.

Post-war fate and legacy

Hermes did not survive to the post-war period; she was sunk on 9 April 1942 by Imperial Japanese Navy aircraft while attempting to reach Ceylon from Colombo approaches. The loss influenced post-war Royal Navy carrier design, doctrine and the development of angled flight deck thinking decades later. Memorials and unit histories in United Kingdom naval museums, regimental records of the Fleet Air Arm, and accounts in works about the Indian Ocean Campaign preserve her legacy. Surviving artifacts and crew lists appear in collections at institutions such as the National Maritime Museum and regimental archives associated with the Royal Naval Reserve.

Modifications and armament

Originally fitted to operate Heinkel-style seaplanes and early Fairey types, Hermes later hosted Gloster Sea Gladiator fighters and Fairey Swordfish torpedo bombers from 815 Naval Air Squadron and others. Anti-aircraft armament evolved from short-range 4-inch mounts to incorporate multiple-gun pom-poms, Oerlikon 20 mm cannons, and improved fire-control systems derived from Admiralty Fire Control Table practice. Radar installations reflecting Type 279 or contemporary British sets were considered for fitment as technology matured. Structural modifications included strengthened flight deck areas, upgraded aircraft lifts influenced by HMS Argus experiments, and enhanced boat and floatplane handling gear for operations alongside cruisers and destroyers.

Command and crew

Hermes' complement included officers and ratings drawn from Royal Navy traditions with commanding officers often promoted from Fleet Air Arm or cruiser commands; notable contemporaries in carrier command doctrine included officers linked to Sir Charles Kennedy-Purvis and admirals of the Eastern Fleet such as Admiral Sir James Somerville. Crews trained in carrier operations alongside aviators from squadrons posted to India and Australia, and embarked observers from Royal Air Force liaison roles during joint operations. Personnel records and muster rolls detail the ship’s complements through interwar deployments, wartime actions, and eventual sinking; survivors' accounts contributed to inquiries and to histories of the Indian Ocean Campaign.
