Operation Sutton
Operation Sutton was the codename for the British amphibious landings at San Carlos Water on East Falkland, initiated on 21 May 1982 as the principal ground phase of the Falklands War to dislodge Argentine forces from the occupied islands.[1][2] The operation, directed by Commodore Michael Clapp of the Amphibious Task Group and Brigadier Julian Thompson commanding 3 Commando Brigade Royal Marines, involved approximately 4,000 to 5,500 troops landing across designated beaches at Port San Carlos, San Carlos, and Ajax Bay, supported by special forces insertions from the SAS and SBS that neutralized Argentine outposts such as at Fanning Head.[1][3][2] Despite achieving tactical surprise through deception operations, the landings faced severe challenges from Argentine air assaults, resulting in the area being dubbed "Bomb Alley" and the loss or damage to several British warships, including the sinking of three vessels out of twenty committed.[2][1] Operation Sutton's defining success lay in securing an unopposed beachhead that enabled the rapid buildup of forces and a subsequent overland advance—requiring a grueling 50-mile trek—to Port Stanley, ultimately precipitating the Argentine capitulation on 14 June 1982, though it highlighted vulnerabilities in anti-air defenses and helicopter logistics, exacerbated by the later sinking of the Atlantic Conveyor.[1][2][3]
Background
Strategic Context of the Falklands War
The Argentine military junta, under General Leopoldo Galtieri, invaded the Falkland Islands on April 2, 1982, primarily to address mounting domestic crises including hyperinflation exceeding 100 percent annually, foreign debt surpassing $40 billion, and mass protests against documented human rights abuses that claimed over 30,000 lives during the Dirty War.[4] [5] The regime, installed via a 1976 coup, viewed the seizure of the long-claimed Islas Malvinas—territories Argentina regarded as usurped by Britain in 1833—as a nationalist rallying cry to unify the populace and legitimize its rule amid eroding support.[6] Preceding the main assault, Argentine forces occupied South Georgia Island on March 3, 1982, testing British resolve with minimal initial pushback, as junta intelligence underestimated London's willingness to contest the remote archipelago 300 miles east of the mainland.[7] Strategically, proximity favored Argentina, enabling rapid air and naval reinforcement from bases 400 miles away, while the junta anticipated international sympathy from Latin American states and a restrained UK response distracted by European commitments.[8] Britain's strategic calculus, conversely, prioritized the principle of self-determination for the islands' 1,800 residents, who in a 1982 poll expressed 99 percent preference for British sovereignty over Argentine rule.[6] Prime Minister Margaret Thatcher's Conservative government, facing approval ratings below 30 percent amid recession and union strife, framed the invasion as an intolerable affront to international norms, necessitating military reclamation to preserve credibility as a global power. On April 5, 1982, Thatcher authorized Operation Corporate, assembling a task force of over 100 ships—including 28 destroyers and frigates—from Ascension Island, 7,600 miles distant, overcoming logistical hurdles via forward basing and voluntary reservist mobilization exceeding 40,000 personnel. This gambit risked naval overstretch against Argentina's air force of 200 combat aircraft but leveraged superior training, intelligence, and subsurface capabilities, including nuclear submarines, to enforce a blockade and isolate the garrison.[8] In the Cold War milieu, the conflict tested hemispheric alliances, with the U.S. initially mediating via Secretary Alexander Haig's shuttles but tilting toward Britain by April 30, 1982, supplying Sidewinder missiles, fuel, and satellite intelligence despite prior anti-communist aid to Argentina's junta. Soviet offers of arms to Buenos Aires underscored ideological fissures, yet Argentina's miscalculation—rooted in overreliance on diplomatic inertia and underestimation of Thatcher's resolve—exposed the junta's strategic isolation, as regional neighbors like Chile provided covert British support fearing Argentine expansionism.[9] The war's brevity, concluding June 14, 1982, with Argentine surrender, affirmed deterrence through credible force projection over negotiation, though at the cost of 255 British and 649 Argentine lives.[6]Planning and Intelligence
Planning for Operation Sutton commenced shortly after the Argentine invasion of the Falklands on 2 April 1982, with initial amphibious strategy developed aboard HMS Fearless by Brigadier Julian Thompson, commander of 3 Commando Brigade, and Commodore Michael Clapp, leader of the Amphibious Task Group.[10] Ewen Southby-Tailyour, a Royal Marines officer with prior knowledge of the islands, contributed detailed charts and hydrographic data acquired during peacetime surveys starting 2 April 1982.[10] Operational objectives for the landings were formalized by Admiral John Fieldhouse on 17 April 1982, emphasizing an unopposed amphibious assault to establish a beachhead.[11] Site options including Cow Bay and Uranie Bay near Stanley were evaluated but discarded due to high risks of immediate counter-attacks and logistical vulnerabilities; San Carlos Water was selected as the preferred location on 10 May 1982 for its sheltered anchorage, minimal swell, and approximately 56-mile distance from Argentine defenses at Stanley, enabling surprise and Rapier air defense deployment.[11][10] Intelligence assessments drew on signals intelligence (SIGINT), aerial and naval reconnaissance, and Argentine force dispositions concentrated around Stanley and Goose Green, indicating sparse coverage in the San Carlos area.[11] Special Boat Service (SBS) teams, supported by SAS elements, conducted ground reconnaissance; SBS personnel departed HMS Conqueror on 26 April 1982 and were inserted by helicopter from 1 May, utilizing beach gradient measuring equipment to evaluate landing sites.[10] These teams confirmed no evidence of minelaying in Falkland Sound or San Carlos Water and reported only minimal Argentine infantry presence, primarily a half-company on Fanning Head overlooking the approaches.[10] A final SBS check of Green Beach occurred immediately prior to the landings, while an SBS raid neutralized the Fanning Head position on 20-21 May 1982 using helicopters from HMS Antrim to eliminate observation posts.[12] SAS operations targeted the Darwin garrison to prevent reinforcement interference.[12] The planning integrated these findings into a phased landing scheme for 21 May 1982 (D-Day), with beaches designated Blue (San Carlos), Red (Ajax Bay), and Green (Port San Carlos); the first wave, including 2 Para and 40 Commando, was scheduled for 0230 but delayed by one hour due to logistical adjustments.[12] Argentine naval assets had been neutralized following the sinking of ARA General Belgrano on 2 May 1982, shifting their focus to air threats, which British planners mitigated through deception operations like preliminary raids.[11] Overall, the intelligence underscored Argentine command-and-control weaknesses and reliance on conscript troops, favoring a maneuver from the sea to exploit terrain and achieve operational surprise.[11]Forces Involved
The primary British ground component for Operation Sutton consisted of 3 Commando Brigade Royal Marines, totaling around 4,000 troops under Brigadier Julian Thompson.[1] [13] This brigade included three Royal Marine Commando units—40, 42, and 45 Commando—each structured with three rifle companies of approximately 120 men, a headquarters company, and a support company equipped for amphibious operations.[14] Attached army elements comprised 2nd Battalion and 3rd Battalion, The Parachute Regiment (2 Para and 3 Para), providing additional infantry capability for the landings.[15] [16] Artillery support was delivered by 29 Commando Regiment, Royal Artillery, while logistics and engineering were handled by units such as 59 Independent Commando Squadron Royal Engineers. The landings on 21 May 1982 were executed using amphibious ships including the Landing Platform Docks HMS Fearless and HMS Intrepid, which served as command and control platforms, alongside the troopship SS Canberra.[1] [13] Specific beach assignments included 3 Para at Green Beach from Intrepid, 45 Commando at Red Beach, and 40 Commando at Ajax Bay (Blue Beach).[13] Naval escort and air defense were provided by a task group of six frigates (including Type 21 vessels like HMS Ardent and HMS Antelope) and two destroyers, screening against expected Argentine air and submarine threats.[14] Air cover relied on Sea Harrier jets operating from aircraft carriers HMS Hermes and HMS Invincible, positioned outside the immediate landing area. Argentine ground forces opposing the San Carlos landings were limited, primarily a detachment from the 25th Infantry Regiment forming Combat Team Güemes, numbering about 62 personnel positioned near Darwin and Goose Green rather than directly at the landing sites.[17] These troops offered minimal initial resistance, with the principal Argentine response involving air strikes by Argentine Air Force jets, including A-4 Skyhawks, Daggers, and Pucará ground-attack aircraft, targeting the British shipping in San Carlos Water.[18] Argentine naval assets, such as submarines, posed a potential threat but did not materially engage during the initial landings.[19]Execution
Approach and Deception
The British amphibious task group for Operation Sutton, centered on the assault ships HMS Fearless and HMS Intrepid, positioned north of the Falkland Islands on 20 May 1982 before entering Falkland Sound via its northern entrance under cover of darkness.[2] Escorted by destroyers including HMS Yarmouth, which led the convoy at 02:15 local time, the force proceeded southward through the 80-mile-long sound to reach San Carlos Water on the western side of East Falkland by approximately 03:45, when the command ships anchored.[10] This route exploited low visibility and the sound's terrain to minimize radar detection, contrasting with Argentine expectations of a southern approach that would expose the fleet to longer scrutiny from coastal defenses.[20] Complementing the physical approach, British deception efforts under Operation Tornado aimed to divert Argentine attention toward Port Stanley and eastern beaches, where intelligence indicated the enemy anticipated the primary assault.[2] HMS Glamorgan executed naval diversions by firing over 100 rounds, including starshell illumination and chaff countermeasures, onto beaches in Berkeley Sound, while Wessex helicopters conducted spoof flights and spurious radio circuits simulated large-scale amphibious preparations south of Stanley, with mock equipment "drifted" inshore to enhance the illusion.[10] Concurrently, Special Air Service (SAS) commandos raided Argentine positions at Goose Green to simulate inland threats, and Special Boat Service (SBS) teams spread disinformation via local contacts near Stanley, fostering ambiguity about British intentions.[2] These measures fragmented Argentine defensive deployments, with garrisons scattered across anticipated sites rather than concentrated at San Carlos, where only minimal forces were present due to prior SBS reconnaissance confirming sparse opposition.[10] The deceptions succeeded in delaying Argentine air reinforcements and ground reactions, allowing initial landing waves—comprising 4,000 troops from 3 Commando Brigade—to secure beaches unopposed during nautical twilight on 21 May, establishing a lodgment before full daylight exposed the position.[20] Argentine high command, misled by the feints and overreliant on flawed intelligence, failed to reposition assets effectively, amplifying the shock of the western landing site's selection.[2]Amphibious Landings
Operation Sutton's amphibious landings began in the early hours of 21 May 1982 at San Carlos Water on East Falkland, targeting multiple beaches including Blue Beach at San Carlos, Green Beach at Port San Carlos, and Red Beach at Ajax Bay.[21] The operation involved approximately 4,000 troops from 3 Commando Brigade, commanded by Brigadier Julian Thompson, including Royal Marine Commandos (40, 42, and 45 Commandos) and elements of 2 and 3 Parachute Regiments.[1] [21] Preceding the main assault, Special Boat Service (SBS) teams conducted a raid on Fanning Head from HMS Antrim to neutralize Argentine observers, while SAS elements pinned down forces at Darwin to prevent reinforcement of the landing area.[21] Landings commenced around 3:30 AM after delays, with the first wave deploying 40 Commando and 2 Para via landing craft utility (LCU) and landing craft vehicle personnel (LCVP) from HMS Fearless and Intrepid onto Blue Beach.[21] The second wave followed, landing 45 Commando on Red Beach and 3 Para on Green Beach, establishing initial footholds with helicopter support from 11 Sea King HC.4s and 5 Wessex HU.5s.[21] [1] Ground opposition was negligible during the landings, as Argentine forces were dispersed and surprised, allowing rapid securing of beachheads by dawn.[21] Following this, amphibious ships including the liner SS Canberra entered San Carlos Water in daylight to disembark reserves such as 42 Commando.[21] Early losses included two Gazelle helicopters shot down east of Port San Carlos before 9:00 AM, killing three British personnel, but the beachhead was consolidated without significant infantry combat.[21] Argentine air attacks intensified post-landing, targeting shipping but not disrupting the initial troop deployment.[1]Naval and Air Engagements
The naval and air engagements accompanying Operation Sutton centered on Argentine Air Force and Naval Aviation strikes against British ships supporting the amphibious landings in San Carlos Water, spanning 21 to 25 May 1982. Lacking surface naval forces in the area, Argentina relied on approximately 180 sorties by fast jets including A-4 Skyhawks from Grupos 4 and 5, IAI Daggers from Grupo 6, and Pucará counter-insurgency aircraft from Grupo 3, launched from mainland bases and forward fields like Goose Green. These low-level attacks aimed to disrupt the landings but faced British defenses comprising Sea Harriers from HMS Hermes and Invincible, shipborne Sea Wolf and Sea Dart missiles, and close-in weapons systems. The confined waters earned the nickname "Bomb Alley" for the intensity of bomb and cannon runs, though British air superiority via carrier-based fighters limited Argentine effectiveness.[22][2] Initial engagements on 21 May followed the unopposed landings around 04:30 local time. At approximately 10:00, two Pucarás from Goose Green strafed HMS Argonaut, inflicting minor cannon damage as the frigate screened the assault force. Subsequent waves escalated: eight Daggers from Grupo 6 struck HMS Broadsword and Antrim with cannon fire and unexploded bombs around 10:30–13:00, while Skyhawks from Rio Grande near-missed HMS Ardent at 13:00 and bombed HMS Argonaut again at 14:30, killing two crewmen. By 15:00, multiple Skyhawk sorties fatally damaged Ardent with bombs amid heavy antiaircraft fire, leading to her abandonment with 22 dead and 30 wounded; she sank the next day. British Sea Harriers from Nos. 800 and 801 Naval Air Squadrons intercepted throughout, downing one Pucará at 12:10, two Skyhawks at 13:05, one Dagger at 14:35, three Daggers at 14:50, and two more Skyhawks at 15:12, with pilots employing Sidewinder missiles in beyond-visual-range shots. Argentine losses that day totaled 11 fixed-wing aircraft, primarily to Sea Harriers and ship defenses, alongside British attrition of one Harrier GR.3 and one Lynx helicopter.[22][22][22] Subsequent days saw continued raids, with 22 May featuring Skyhawk and Dagger attacks damaging HMS Brilliant and others, though Sea Harriers claimed additional kills without air-to-air losses. On 23 May, HMS Antelope was struck by unexploded bombs during a low-level bombing run, detonating later that evening and sinking her with one fatality. The 25 May climax included the sinking of Type 42 destroyer HMS Coventry by Skyhawks after she shifted to antiair warfare duties, killing 19, and an Exocet missile strike on the logistics ship SS Atlantic Conveyor, destroying four Chinook helicopters but not halting the operation. Overall, British naval losses comprised three ships sunk (Ardent, Antelope, Coventry) and five damaged from the 20-vessel task group, with 49 personnel killed across the engagements; Argentine aviation forfeited around 25 aircraft to Sea Harriers (which flew 126 sorties without combat loss) and surface defenses, underscoring the asymmetry where carrier denial forced high-risk mainland launches without fighter escort. Ground-based Rapier missiles proved largely ineffective due to clutter and logistics, while man-portable Blowpipes downed one raider amid reliability issues. These clashes secured the beachhead despite costs, enabling 3 Commando Brigade's inland push.[2][22][2]Aftermath
Beachhead Consolidation
Following the unopposed amphibious landings commencing around 0230 hours on 21 May 1982, British forces rapidly secured the initial beachheads at San Carlos Water. The 40 Commando Royal Marines established positions at Blue Beach near San Carlos, advancing to occupy the Verde Mountains, while the 45 Commando secured Red Beach at Ajax Bay and the 3rd Battalion, Parachute Regiment took Green Beach at Port San Carlos. The Special Boat Service neutralized Argentine outposts at Fanning Head with supporting fire from HMS Antrim, and elements of D Squadron, 22 Special Air Service Regiment pinned down the Darwin garrison using gunfire from HMS Ardent to prevent interference. These actions ensured the lodgement spanned approximately four miles by dawn, with minimal ground resistance encountered.[21][23] Defensive measures were prioritized to protect the perimeter, including the deployment of twelve Rapier surface-to-air missile firing posts by T Battery, Royal Artillery, around San Carlos Water, alongside 105mm light guns from the 29th Commando Regiment Royal Artillery and 4th Field Regiment Royal Artillery. Troops dug in on surrounding high ground, such as Sussex Mountain occupied by 2nd Battalion, Parachute Regiment, to establish observation and firing positions. Logistical consolidation involved unloading ammunition, fuel, and rations from amphibious ships like HMS Fearless and Intrepid via landing craft and helicopters, including Sea King from 846 Naval Air Squadron; the brigade support area was set up at Ajax Bay, where a field dressing station was established by the Surgical Support Team. The 42 Commando Royal Marines, held in reserve aboard SS Canberra, landed subsequently at Port San Carlos to reinforce the buildup.[21][19][24] Argentine responses focused on air attacks rather than ground counteroffensives, with low-level strikes by Pucará aircraft and A-4 Skyhawks prompting defensive fire from Rapier systems, Blowpipe and Stinger man-portable missiles, naval guns, and small arms; two British Gazelle helicopters were lost to ground fire on 21 May, killing three crew members. Despite these threats, which damaged ships and disrupted unloading, Brigadier Julian Thompson's 3 Commando Brigade consolidated the beachhead over the following days, expanding it to about ten square miles by 27 May without significant territorial concessions. This phase enabled the landing of over 4,000 troops and essential supplies, transitioning the focus from defense to preparations for inland advances toward key objectives like Darwin and Goose Green.[21][24][19]Inland Advance
Following the establishment of the San Carlos beachhead, British ground forces under 3 Commando Brigade began advancing inland on East Falkland to secure flanks, disrupt Argentine defenses, and position for a push toward Stanley, approximately 56 miles (90 km) distant across rugged peat moorland and streams.[6] Brigadier Julian Thompson prioritized rapid movement to exploit surprise, with 2nd Battalion, Parachute Regiment (2 Para) assigned to neutralize Argentine positions at Darwin and Goose Green, 13 miles (21 km) southeast, held by elements of the Argentine 12th Infantry Regiment.[15] The advance commenced on 27 May 1982 amid poor weather, with 2 Para tabbing over trackless terrain without vehicular support, reaching assembly areas by evening despite fatigue from prior air attacks during the landings.[25] The assault on Goose Green began at 2:30 a.m. on 28 May, with 2 Para—numbering around 450 men—outnumbered by an estimated 600-700 Argentine defenders equipped with artillery, machine guns, and anti-tank weapons in prepared positions along a narrow isthmus.[3] Lacking immediate helicopter-delivered artillery or air support due to logistical delays, Lieutenant Colonel Herbert Jones led companies in a dismounted infantry attack, methodically clearing strongpoints under fire; Jones was killed during a bayonet charge on a trench line near Darwin Hill.[15] After 14 hours of close-quarters fighting involving small arms, grenades, and limited 105mm gun fire from supporting batteries, Major Chris Keeble coordinated the final push, prompting an Argentine surrender by 10:00 a.m. on 29 May that yielded 1,100 prisoners, including conscripts and local civilians.[25] British casualties totaled 17 killed and 40 wounded, highlighting the risks of light infantry tactics against fortified foes without full combined-arms integration.[3] Parallel to 2 Para's operation, elements of 40 and 42 Commandos advanced northeast from San Carlos toward Teal Inlet and Douglas Settlement by late May, securing high ground like Mount Kent via helicopter insertions to facilitate resupply and reconnaissance for the main thrust on Stanley.[6] These moves expanded the lodgment area to over 100 square miles (260 km²) by early June, though slowed by minefields, harassing artillery, and the need to airlift heavy equipment ashore. Argentine air interdiction continued to threaten lines of communication, but the inland gains prevented effective counterattacks and forced the withdrawal of forward Argentine units.[15]Logistical Challenges
The amphibious landings of Operation Sutton at San Carlos Water on 21 May 1982 faced severe logistical constraints stemming from the 8,000-mile supply line from the United Kingdom and the absence of air superiority, compelling British forces to rely on sea-based resupply vulnerable to Argentine air strikes.[26] Initial plans envisioned maintaining most supplies afloat offshore to facilitate rapid redistribution, but recurrent attacks rendered this untenable, forcing an abrupt shift to ashore storage at limited beachheads like Ajax Bay.[26] Unloading operations, conducted primarily via landing craft from HMS Fearless and Intrepid—each deploying four LCVPs for personnel and four LCUs for vehicles exceeding their 60-tonne capacity—were hampered by terrain unsuitable for beaching larger vessels like LSLs, which instead used Mexeflotes to transfer over 75% of stores, often in overload configurations up to 200 tonnes.[27] Argentine air assaults in the designated "Bomb Alley" disrupted offloading, with ships required to withdraw immediately after transfers except during active unloading windows, slowing the build-up of the 9,000 tonnes of prepared supplies and tying up helicopters and landing craft for approximately one week.[27] [26] Ajax Bay, repurposed as the primary logistics hub under 3 Commando Brigade's Logistics Support Regiment, suffered a direct bomb hit on its ammunition dump, killing six personnel and wounding 27 while igniting fires, though two unexploded ordnance items averted greater catastrophe. Fuel distribution proved particularly inefficient, depending on jerrycans and Bedford POD vehicles across boggy ground stabilized by improvised Class 30 Trackway and Centurion BARVs, with no formalized fuel policy exacerbating shortages.[27] Further complications arose from operational delays and equipment losses; the 2nd Battalion, Parachute Regiment's embarkation was postponed due to inadequate prior training with landing craft, resulting in one soldier's pelvic injury and compressing the timeline for full supply discharge.[1] The sinking of Atlantic Conveyor by an Exocet missile on 25 May destroyed most heavy-lift Chinook helicopters, compelling infantry units to "yomp" over 50 miles inland with bergens limited to essential loads amid harsh weather and roadless terrain, severely straining ammunition, water, and medical resupply chains.[1] [26] Medical facilities at Ajax Bay operated with rudimentary resources, lacking sterile water, autoclaves, and diathermy machines, while endemic diarrhoea plagued troops from contaminated sources, underscoring the austere environmental demands.[26] These issues were partially mitigated through STUFT vessels and Eager Beaver forklifts for pallet handling, but poor initial packing and palletization delayed onward distribution from beach support areas.[27]Casualties and Losses
British Losses
During Operation Sutton, British losses were predominantly naval, resulting from intense Argentine air attacks on ships providing close support for the amphibious landings in San Carlos Water from 21 to 25 May 1982. These strikes sank three warships and severely damaged several others, accounting for the majority of fatalities. Ground forces encountered minimal opposition during the initial assaults, sustaining few casualties ashore.[28] The most significant losses occurred aboard frigates and destroyers targeted by A-4 Skyhawk and other aircraft dropping unguided bombs. HMS Ardent, acting as a picket ship, was overwhelmed by multiple bomb hits on 21 May, leading to uncontrollable fires; she capsized and sank the following day, with 22 crew members killed out of 199 aboard.[29][30] HMS Antelope suffered two unexploded bomb penetrations on 23 May; an attempt to defuse one the next day triggered a massive explosion that broke the ship in two, resulting in 2 deaths.[31][32] HMS Coventry, deployed for air defense cover on 25 May, absorbed at least three direct bomb hits from low-level attacks, sinking rapidly with 19 sailors killed and around 30 injured.[33]| Ship | Date Sunk/Destroyed | Cause | Fatalities |
|---|---|---|---|
| HMS Ardent | 22 May 1982 | Multiple bomb hits | 22 |
| HMS Antelope | 24 May 1982 | Bomb defusal explosion | 2 |
| HMS Coventry | 25 May 1982 | Three bomb hits | 19 |
Argentine Losses
Argentine losses during Operation Sutton, spanning May 21 to 25, 1982, were primarily inflicted on air assets attempting to disrupt the British amphibious landings at San Carlos Water, with the Argentine Air Force launching multiple sorties using low-level tactics to evade radar detection. These efforts resulted in the destruction of 21 aircraft, including nine A-4 Skyhawk variants, six Daggers, two Pucarás, three Pumas, and one Agusta A-109, many downed by Royal Navy Sea Harriers employing Sidewinder missiles and 30mm cannon fire, or by ship- and ground-based surface-to-air missiles such as Sea Cat, Sea Wolf, and Rapier. At least nine pilots were killed in these engagements, with others ejecting and being captured or rescued, reflecting the high attrition rate from British combat air patrols and layered defenses.[35]| Aircraft Type | Number Lost | Notable Incidents |
|---|---|---|
| A-4 Skyhawk (B/C/Q variants) | 9 | Multiple shot down by Sea Harriers on May 21 near Swan Island and Chartres; additional losses over San Carlos Water on May 23–25 by SAMs including Sea Dart. |
| Dagger A | 6 | Engaged by Sea Harriers on May 21–24 north of Pebble Island and near Fanning Head; three downed in a single five-second burst on May 24. |
| Pucará | 2 | Ground-attack aircraft hit by Stinger and Sea Harrier on May 21 near Sussex Mountains and Darwin. |
| Puma SA.330L | 3 | Helicopters damaged or crashed evading Sea Harriers on May 21–23 near Mount Kent and Shag Cove. |
| Agusta A-109A | 1 | Destroyed by Sea Harriers on May 23 near Shag Cove House. |
