HMS Theseus (R64)

The HMS Theseus was laid down to serve in the Second World War, but was not completed until February 9th, 1946, after peace was declared in 1945. The HMS Theseus was then utilized as a training vessel until the outbreak of the Korean War.

In 1946, Theseus embarked on work-up and embarked aircraft, conducted trials, and a further work-up for operational service.[1] After preparation for duty in the Far East, she sailed to join the British Pacific Fleet at Singapore as Flagship for the Flag Officer Air, Far East. In 1947, she deployed as the Flagship of the 1st Aircraft Carrier Squadron of the British Pacific Fleet. Upon return to the UK she was refitted for service in the Home Fleet. upon completion, she joined the 3rd Aircraft Carrier Squadron, Home Fleet.

In 1950, with the beginning of the Korean War, the Theseus was deployed to Korea, commencing standard carrier operations. Her first operation involved suppressing enemy defense's and communications at Chinnampo, among other locations. Her second operational patrol involved only Combat Air Patrols (CAP), because her take-off weight capacity was limited by a dysfunctional catapult, and thus aircraft were unable to be armed with rockets and bombs. Her third operational duty was part of the Commonwealth Task Force. Theseus sailed with accompanying ships from Sasebo in Japan. The carrier's aircraft launched successful air strikes on bridges, North Korean troops, and other opportune targets. The HMS Theseus's operations in the Korean War primarily concentrated on the Chinnampo area, resulting in widespread damage to the area.

During her fourth operational patrol, which began in December of 1950, aircraft from Theseus sighted and fired on numerous ground vehicles in the north of the separated country, with heavy snow covering the area. The destruction resulted in many of the targeted vehicles being destroyed. Soon afterwards, Chinese troops became the target of attacks from the carrier's aircraft, which after their fourth tour had completed over 1,630 hours in the air and had fired over 1,400 rockets.

The next year, on January 5th, 1951, Theseus began her fifth operational patrol, supporting the American 25th Division, who were fighting south of Osan in South Korea. On January 15th, the Theseus Achieved the milestone of 1,000 accident-free landings. The Carrier Air Group (CAG) were awarded the Boyd Trophy for a remarkable operational tour of duty that included many firsts for pilots and aircrew.

The sixth operational patrol, in late January 1951, was scattered with several major and minor accidents. On January 26th, an aircraft appeared to shudder, before spinning out of control and into the sea. The C-class destroyer Cossack went to the location of the crash but to no avail. A second aircraft was hit a number of times by anti-aircraft gunfire, forcing the pilot to ditch the aircraft in a valley in an area near Tongduchon-ni. The pilot waited for rescue for about ninety minutes. An American helicopter flew in and picked up the pilot, while other aircraft from Theseus flew a close-air patrol over the area. On 2 February, a Sea Fury burst a tire while landing, straining the fuselage and bring the number of accident-free landings to an end at 1,463.

The seventh operational patrol started off poorly when a squadron of Fairey Fireflies, returning from a reconnaissance mission experienced weapon misfires, causing one fatality. Further similar missions were flown, as well as close air support for the U.S. IX Corps in the Wonju area.

The eighth operational patrol, beginning on March 4th 1951, saw much of the same, with patrols over the now-familiar area of Chinnampo to Kuhsa-Sung to create the illusion of an imminent amphibious assault. Two more crashes occurred, the first incurring no casualties, but the second proving fatal with an aircraft crashing while returning to Theseus.

The ninth operational patrol opened with the shooting down of another aircraft at Suwon on 24 March. Further reconnaissance and CAS missions were flown, including an attack on six enemy vessels.

The tenth operational patrol began on 8 April operating in the Sea of Japan, with the accompanying American carrier USS Bataan, together with an allied destroyer screen, comprising HMS Consort, HMAS Bataan, HMCS Huron, USS English and USS Sperry. On 10 April, two Sea Furies were attacked by American Corsairs in a friendly-fire incident. One Sea Fury was seriously damaged, the other, after much maneuvering, escaped unscathed. Two other Sea Furies performing reconnaissance duties nearby heard the call for assistance. However, while on the way there, one was shot down, the pilot being taken prisoner. Another aircraft searching for the first was shot down by flak, but the pilot escaped capture.

Two more aircraft were shot down soon afterwards. The first landed only forty miles from the Theseus, damaged by flak and was soon rescued by helicopter. The second, hit by flak crashed into a paddy field then skidded into a dry river bed where it came under small arms fire from North Korean troops. The remaining aircraft from the flight acted as a RESCAP (Rescue Close Air Patrol) while a further two Sea Furies escorted a helicopter en-route to the downed pilot's location. After thirty eight minutes, the pilot, severely injured, was rescued.

Further successful strikes were launched on numerous North Korean targets. During these strikes another aircraft from the carrier's flight complement was shot down. The downed pilot was rescued by an American helicopter pilot who was later awarded the Distinguished Service Cross for successfully carrying out a courageous rescue despite heavy small arms fire from North Korean troops. He was awarded the honor at the British Consulate in Seattle.

On 15 January 1952, the allied task force operations ended with departure of the American carrier Bataan. Theseus herself continued operations in Korea, this time on the west coast. An aircraft from Theseus was ditched due to engine failure, the pilot spending 55 minutes in a rough sea until being rescued. Two days later, operations from Theseus ended. Theseus was replaced by sister ship Glory and departed from Sasebo.

Naval-history.net records state that in late 1951 Theseus joined the Home Fleet as Flagship, 2nd Aircraft Carrier Squadron.[1] In 1952, she became Home Fleet Flagship, and then was detached to the Mediterranean to relieve Glory for service with the United Nations' effort off Korea. She took part in joint exercises in Mediterranean with Home Fleet ships. In February–March 1952, Theseus, with the 14th Carrier Air Group embarked, took part in the NATO Exercise Grand Slam in the Mediterranean.

In 1953 she took part in the Fleet Review to celebrate the Coronation of Queen Elizabeth II.[2]

In 1956, Theseus was used as an emergency commando carrier, along with Ocean, during the Suez Crisis. From November to December, helicopters from Theseus transported troops ashore, as well as evacuating wounded soldiers. Compared to her actions during the Korean War, her role at Suez was relatively quiet. The following year she was placed in reserve. She was subsequently broken up at Inverkeithing in 1962.
