Lieutenant-Commander Stephen Harrison-Thomas DSC (born 1961), known during his naval service as Steve Thomas, is a former Royal Navy Fleet Air Arm officer and Sea Harrier pilot who served with 801 Naval Air Squadron during the Falklands War.
During the conflict, he flew over fifty operational sorties in the air defence role from HMS Invincible and was awarded the Distinguished Service Cross for gallantry. His service is described in published accounts of the Falklands air war, including works by Nigel Ward and other historians, in connection with air combat engagements against Argentine aircraft.
The role of Sea Harrier pilots, including Thomas, has been identified in historical studies as a key factor in establishing British air superiority during the conflict despite numerical and technical disadvantages.
Thomas was born in Yorkshire in 1961. In May 1978, he underwent various tests and examinations at the Aircrew Selection Centre, at RAF Biggin Hill, along with further tests and interviews at HMS Daedalus, and interviews at the Admiralty Interview Board, . He joined Britannia Royal Naval College, Dartmouth in October 1978 as an officer under training with the rank of Midshipman.
After basic flying training, he completed advanced instruction with the Fleet Air Arm on the Bae Hawk at RAF Valley, followed by conversion to the two-seat Harrier T4. He graduated from the Operational Flying Training Unit, 899 Naval Air Squadron, before joining 801 NAS under the command of Lieutenant-Commander Nigel "Sharkey" Ward. He subsequently flew the Sea Harrier FRS1 from .
Thomas, as a newly commissioned pilot with 801 Naval Air Squadron, participated in a deployment to the Air Combat Manoeuvring Installation (ACMI) at Decimomannu, Cagliari, Sardinia, under the command of Lieutenant-Commander Nigel âÂÂSharkeyâ Ward. The detachment involved tri-national fighter combat training exercises against U.S. Air Force F-15 âÂÂBitburg Eaglesâ and U.S. Navy Aggressor F-5Es. Despite the technical superiority of the opposing aircraft, the Sea Harrier pilots, including Thomas, achieved notable success through disciplined handling and strategic acumen.
Thomas embarked on Invincible on 3 April 1982 for the journey South.
Lieutenant Steveâ¯Thomas and Flight Lieutenant Paulâ¯Barton were on a Combat Air Patrol West of Invincible over West Falkland, at approximately 35,000â¯ft, when they were vectored toward two Argentine Mirage IIIEA fighters to the North. Barton engaged, launching an AIMâÂÂ9L Sidewinder which destroyed the rearmost Mirage. The pilot, Ltâ¯Rubén Perona, ejected safely. This was the first British airâÂÂtoâÂÂair kill since the Korean War.
Thomas fired a Sidewinder at the second Mirage just as it disappeared into cloud, but the missile failed to detonate. The missile was reported to have damaged the aircraft however and because of this, the pilot, Captâ¯Gustavo Cuerva, now also low on fuel, flew to Stanley, but was shot down and killed by Argentine antiâÂÂaircraft defences while attempting to land. Thomas was credited with the kill.
Lieutenant-Commander Ward, was leading a division of three aircraft on a Combat Air Patrol, Southwest of San Carlos Water with Steve Thomas and Alisdair Craig. Two Pucaras operating from Goose Green were detected by HMS Brilliant and the Harriers were vectored to intercept. One of the Pucaras was attacked from abeam by Thomas and Craig without being hit. Simultaneously, Ward attacked the second flown by Major Carlos Tomba from behind with his cannon, and shot it down. Tomba ejected from the Pucara at very low-level and walked back to Goose Green.
Later that day, Thomas as Wards wingman, were flying a low-level combat air patrol west of San Carlos. Ward spotted two Argentine Air Force Mirage V "Daggers" approaching at low level heading towards the landing beaches around San Carlos. Ward flew head-on between them, forcing them to turn away. This brought them directly in front of Thomas, who shot down both aircraft with Sidewinder missiles. A third Dagger, approaching from behind, fired on Ward but missed, Ward then turned and destroyed it with a Sidewinder. All three Argentine pilots; Major Piuma, Captain Donadille, and Lieutenant Senn, ejected safely. A fourth Dagger evaded interception and attacked Brilliant, causing minor damage.
On the flight back to Invincible Thomas went on to say
The Battle of Goose Green was fought from 28 to 29 May 1982 on East FalklandâÂÂs central isthmus, the site of a tactically important airfield. On 29 May, the 2nd Battalion, Parachute Regiment (2 Para) were pinned down by well-positioned 35mm anti-aircraft guns, preventing further movement and causing casualties.
Three Sea Harriers, Lieutenant Nigel "Sharkey" Ward (XZ451), Lieutenant Steve Thomas (XZ453), and Flight Lieutenant Ian Mortimer (XZ459), each armed with either 2.75-inch FFAR rockets or cluster bombs, strafed the Argentine gun positions.
Second Lieutenant Claudio Braghini, Commander of the Argentine 35mm AA guns, recalled:
Corporal John Geddes of Patrols Platoon, 2Para, later wrote:
The Sea Harriers, however, made much more of an impact, at least psychologically. As one of the British company commanders put it: âÂÂThey frightened me shitless, never mind the ArgentiniansâÂÂ. Some people have seen the Harrier strike as the decisive action of the battle. The cluster bombs and rockets made a lot of noise, but did little collateral damage - they just moved a lot of mud sideways, as another of the pilots put it. Nevertheless, coming at a time when the Argentinians had their backs to the wall having just withdrawn into Goose Green, it seems reasonable to agree with the British battlegroup commander Chris Keeble, that the Harriers finally cracked the Argentiniansâ will to fight.
On 1 June 1982, Steve Thomas and Ward were in the climb returning to Invincible after combat air patrol when they were alerted by to a radar contact 40 miles to the Northwest. The pair turned towards the position and acquired a target using their Blue Fox radar at a range of 38 miles and an altitude of 4,000 feet below their position. The target, a four-engine Lockheed C-130 Hercules, was heading West towards Argentina while descending. As the Harriers closed, Ward visually identified the aircraft and engaged immediately. His first missile missed, but the second struck between the starboard engines. He then fired 240 rounds from his aircraft's cannons, causing the Hercules to crash into the sea, killing all seven crew members.
Thomas flew over fifty operational missions during the Falklands War in the air defence role from HMS Invincible. He was involved in multiple air combat engagements against Argentine aircraft and is credited in published accounts with several air-to-air victories, as well as participation in a number of additional engagements during the conflict.
Some accounts credit Thomas with three fast-jet victories during the conflict, although individual combat claims in the Falklands air war have been subject to differing interpretations in the literature.
At the time of the conflict, he was among the less experienced Sea Harrier pilots in operational service, having relatively limited flying hours on the type. Despite this, he took part in several significant engagements described in historical accounts of the air campaign.
For his actions during the campaign, he was awarded the Distinguished Service Cross for gallantry.
Thomas subsequently served at the Aeroplane and Armament Experimental Establishment (AAEE), Boscombe Down as a test pilot until 1988, working on Upgrade of FRS1 to the F/A 2, featuring the Blue Vixen pulse-doppler radar and the AIM-120 AMRAAM missile as well as the Air-to-Air Refueling (AAR) Probe. These trials and tests were critical in developing and refining new aircraft and weapon systems and improving the capabilities of existing ones. The AAEE at Boscombe Down played a vital role in ensuring the effectiveness and safety of British military aviation during this period.
Stephen retired from the Royal Navy in 1989 with the rank of Lieutenant-Commander. He embarked on a civilian aviation career, starting as a First Officer and then becoming Captain at Air UK, a regional airline. He flew the BAe 146 Regional Jetliner on European routes from Manchester and later operated Boeing 737-400 for Air UK Leisure from Luton Airport. After KLM bought Air UK, he moved to the Netherlands and served as a Captain on Boeing 767-300 ER on South American routes.
The role of Fleet Air Arm Sea Harrier pilots during the Falklands War has been widely discussed in historical analyses of the conflict, particularly in relation to the establishment of British air superiority despite numerical and technical disadvantages. Lawrence Freedman, in The Official History of the Falklands Campaign, emphasises the decisive contribution of Sea Harrier operations in protecting the Task Force and countering Argentine air attacks.
Within this context, Thomas's operational service forms part of a body of documented air combat engagements described in multiple secondary sources. Accounts of the air war, including Nigel Ward's Sea Harrier Over the Falklands and the British Aviation Research Group's Falklands: The Air War, describe engagements in which Sea Harrier pilots, including Thomas, were involved in interceptions against Mirage and Dagger aircraft during key phases of the conflict.
Historians and aviation writers have noted that these engagements were often conducted under demanding conditions, including low-level operations, limited radar coverage, and fuel constraints, placing significant emphasis on pilot skill and tactical coordination. The performance of Sea Harrier pilots in such circumstances has been cited as a critical factor in limiting Argentine air effectiveness over the islands.
Thomas's award of the Distinguished Service Cross further reflects contemporary recognition of his operational performance. The official citation highlights his participation in multiple engagements, his effectiveness in air combat, and his ability to recover safely under adverse conditions, including damage to his aircraft and loss of communications.
While individual combat claims in the Falklands air war have been subject to varying interpretations in different sources, Thomas is consistently associated with several air combat engagements described in published accounts of the campaign, placing his service within the broader operational narrative of the conflict.
Thomas's subsequent service as a test pilot at the Aeroplane and Armament Experimental Establishment (AAEE), Boscombe Down, has also been noted in the context of post-war development of the Sea Harrier, including work associated with upgrades to later variants.
