Centurion (tank)

On 14 November 1950, the British Army's 8th King's Royal Irish Hussars, equipped with three squadrons of Centurion Mk 3 tanks, landed in Pusan. The first recorded Centurion kill occurred in Busan against a North Korean captured Cromwell tank.[29] Operating in sub-zero temperatures, the 8th Hussars learnt the rigors of winter warfare: their tanks had to be parked on straw to prevent the steel tracks from freezing to the ground. Engines had to be started every half-hour, with each gear being engaged in turn to prevent them from being frozen into place.[30] During the Battle of the Imjin River, Centurions won lasting fame when they covered the withdrawal of the 29th Brigade, with the loss of five tanks, most later recovered and repaired.[31] In 1952, Centurions of the 5th Royal Inniskilling Dragoon Guards were also involved in the Second Battle of the Hook where they played a significant role in repelling Chinese attacks. Centurions of the 1st Royal Tank Regiment participated in the Third Battle of the Hook[31] repelling the PLA and also were involved in the Battle of the Samichon River in 1953. In a tribute to the 8th Hussars, General John O'Daniel, commanding the US 1st Corps, stated: "In their Centurions, the 8th Hussars have evolved a new type of tank warfare. They taught us that anywhere a tank can go, is tank country: even the tops of mountains."[30] The lack of pintle-mounted machine guns on the turret meant that the Centurion was only able to fire in one direction and so was vulnerable to infantry attacks.[32]

During the Suez Crisis, British ground commander General Hugh Stockwell believed that methodical and systematic armoured operations centred on the Centurion would be the key to victory.[33]

The Egyptians destroyed Port Said's Inner Harbour, which forced the British to improvise and use the Fishing Harbour to land their forces. The 2nd Bn of the Parachute Regiment landed by ship in the harbour. Centurions of the British 6th Royal Tank Regiment were landed and by 12:00 they had reached the French paratroopers. While the British were landing at Port Said, the men of the 2 RPC at Raswa fought off Egyptian counter-attacks featuring SU-100 tank destroyers.[34]

After establishing themselves in a position in downtown Port Said, 42 Commando headed down the Shari Muhammad Ali, the main north–south road to link up with the French forces at the Raswa bridge and the Inner Basin lock. While doing so, the Marines also took Port Said's gasworks. Meanwhile, 40 Commando supported by the Royal Tank Regiment remained engaged in clearing the downtown of Egyptian snipers. Lieutenant Colonel Norman Tailyour arranged for more reinforcements to be brought in via helicopter.[35]

In 1967, the Royal Australian Armoured Corps' (RAAC), 1st Armoured Personnel Carrier (APC) Squadron transferred to "A" Squadron, 3rd Cavalry Regiment in South Vietnam. Although they successfully conducted combat operations in their areas of operations, reports from the field stated that their lightly-armoured M113A1 armoured personnel carriers were unable to force their way through dense jungle[36] limiting their offensive actions against enemy forces. The Australian government, under criticism in Parliament, decided to send a squadron of Australian Centurion tanks to South Vietnam.[36] The 20-pdr armed[37] Australian Centurions of 'C' Squadron, 1st Armoured Regiment landed in South Vietnam on 24 February 1968, being headquartered at Nui Dat in III Corps (MR3).[38]

Colonel Donald Dunstan, later to be governor of South Australia, was the deputy task force commander of the 1st Australian Task Force (1 ATF) in South Vietnam[39] Dunstan had quite possibly been the last Australian to use tanks and infantry in a combined operation during the Second World War, (as part of the Bougainville campaign), and the first since the war to command Australia's tanks and infantry in combat.[40] When he temporarily took over command during Brigadier Ronald Hughes's absence, he directed that the Centurions be brought up from Nui Dat to reinforce firebases Coral and Balmoral, believing that they were a strong element that were not being used. Besides adding a great deal of firepower, Dunstan stated, he "couldn't see any reason why they [the Centurions] shouldn't be there".[41] His foresight enabled 1 ATF to kill approximately 267 soldiers of the People's Army of Vietnam 141st and 165th Regiments during the six-week-long Battle of Coral–Balmoral in May 1968, as well as capturing 11 prisoners, 36 crew-served weapons, 112 small arms, and other miscellaneous enemy weapons.[42]

Troops of the 1st Armoured Regiment during a briefing at Vung Tau

After the Battle of Coral-Balmoral, a third Centurion troop, which included two tankdozers, was formed. By September 1968, 'C' Squadron was brought to its full strength of four troops, each equipped with four Centurion tanks. By 1969, 'B' Squadron, 3rd Cavalry; 'A' Squadron, 1st Armoured Regiment; 'B' Squadron, 1st Armoured Regiment; and 'C' Squadron, 1st Armoured Regiment, had all made rotations through South Vietnam. Originally deployed as 26 Centurion tanks, after three and a half years of combat operations, 58 Centurions had served in country; 42 had suffered battle damage with six beyond repair and two crewmen had been killed in action.[36]

The Centurion crews, after operating for a few weeks in country, soon learned to remove the protective armoured side skirts from both sides of the tank, to prevent the vegetation and mud from building up between the track and the mudguards. Each Centurion in Vietnam normally carried a basic load of 62 rounds of 20 pounder shells, 4,000 rounds of .50 cal and 9,000 rounds of .30 cal machine gun ammunition for the tank commander's machine gun as well as the two coaxial machine guns.[43] They were equipped with petrol engines, which necessitated the use of an extra externally mounted 100-imperial-gallon (450 L) fuel tank, which was attached to the vehicle's rear.[37][44]

In 1965, the bulk of India's tank fleet was older M4 Sherman tanks, but India also had Centurion Mk.7 tanks, with the 20 pounder gun, and also AMX-13 and M3 Stuart light tanks. The Centurion Mk.7 at that time was one of the most modern western tanks.[45][46]

The offensive of Pakistan's 1st Armoured Division was blunted at the Battle of Asal Uttar on 10 September. Six Pakistani armored regiments were opposed by three Indian armoured regiments. One of these regiments, 3 Cavalry, fielded 45 Centurion tanks. The Centurion, with its 20 pounder gun and heavy armour, proved to be more than a match for the M47 and M48 Pattons.[47] On the other side, when Pakistani Army armoured division primary composed of M47 Pattons and M48 Pattons, they proved to be only able to penetrate a few of the Centurion tanks, as witnessed in the Battle of Chawinda in the Sialkot sector. A post-war US study of the tank battles in South Asia concluded that the Patton's armor could, in fact, be penetrated by the 20-pounder tank gun (84 mm) of the Centurion (later replaced by the even-more successful L7 105mm gun on the Mk. 7 version which India also possessed) as well as the 75 mm tank gun of the AMX-13 light tank.

In 1971, at the Battle of Basantar, an armoured division and an armoured brigade of the Pakistani I Corps confronted two armoured brigades of the Indian I Corps, which had Centurion tanks. This resulted in a substantial tank battle, between the American-built tanks of the Pakistani Army and the Indian Army's mixture of Soviet T-55s and British Centurions. Casualties were heavily skewed against the Pakistani force, with 46 tanks destroyed.

Israeli Sho't variant

The first country which bought Centurion tanks was Egypt. The first tanks were received in 1950.[48] Israel's formerly British Centurions were first delivered in 1959. Differing varieties of the Centurion were bought by Israel over the years from many different countries or captured in combat. Following their acquisition the Israelis quickly up-graded the tanks with British 105 mm L7 instead of the original 20-pounder main gun and renamed them Sho't ("scourge" or "whip").[49] When the Six-day War broke out in 1967, the Israel Defense Forces (IDF) had 293 Centurion / Sho't tanks that were ready for combat[50] out of a total of 385 tanks. In Sinai Egypt had 30 Centurion tanks.[51] All 30 Egyptian tanks were destroyed or captured by Israel during the conflict.[52] Israel also captured about 30 Jordanian Centurion tanks from a total of 90 in Jordanian service. 25 tanks were abandoned in Hebron by the 10th Jordanian Independent Tank Regiment.[53][54]

All Sho't tanks were upgraded with the more efficient Continental AVDS-1790-2A diesel engine (also used in the M48 and the M60 tanks) and an Allison CD850-6 transmission from 1970 to 1974. The upgraded version was named Sho't Kal Alef and was followed by three additional sub variants called Bet, Gimel and Dalet according to the upgrades added.[30] The upgrades included thicker armour, new turret rotating mechanism, new gun stabiliser, improved ammunition layout with more rounds and increased fuel capacity. A modern fire control system, an improved fire extinguisher system, better electrical system and brakes, and the capability of installing reactive armour completed the modifications. They have American radios and either have the original 7.62 mm calibre MG on the commander's cupola or a 12.7 mm calibre HMG. The Sho't Kal can be distinguished from the Centurion by its raised rear deck, to accommodate the bigger engine.

The Sho't Kal version of Centurion earned its legendary status during the Battle of "The Valley of Tears" on the Golan Heights in the 1973 Yom Kippur War. 105 Sho't Kal tanks of the 7th Armoured Brigade and 20 Sho't tanks of the 188th Brigade defeated the advance of some 500 Syrian T-55s and T-62s and the Sho't Kal became emblematic of Israeli armour's prowess.[55] During the entire war, 1,063 Israeli tanks were disabled[56] (more than half of them Centurions), about 600 of them were completely destroyed or captured.[57] Some 35 Israeli Centurions were captured by Egypt,[58] dozens more were captured by Syria, Iraq[59] and 4 by Jordan.[60] On the other hand, 2,250 Arab tanks were disabled[56] (including 33 Jordanian Centurions, 18 of them destroyed[61]), 1,274 of them were completely destroyed or captured[62] (643 tanks were lost in the north and 631 were lost in the south[63]). After the war, to replace Israeli losses, the United States delivered 200 M60 and M48 tanks[64] and the United Kingdom delivered 400 Centurion tanks to Israel.[57]

Sho't Kal tanks with Blazer reactive armour package were used in the 1982 invasion of Lebanon. During the war, 21 Centurion tanks were knocked out, 8 of them were destroyed.[65]

The Israelis started to retire the Sho't Kal during 1980s and they were completely retired during the 1990s. Most of them were converted to Nagmasho't, Nagmachon, and Nakpadon heavy Infantry Fighting Vehicles and Puma armored engineering vehicles.

In the 1991 first Gulf War, 12 FV4003 Centurion Mk5 AVREs were deployed with 32 Armoured Engineer Regiment as part of British operations during the war. Three were lost in training in two separate incidents involving vehicle fires and detonation of munitions. One AVRE was destroyed on 5 February 1991 and two were destroyed in a second incident the next day.[66] Four minor injuries were sustained.

Fifty Centurions were purchased by Jordan between 1954 and 1956 and by 1967 about 90 Centurions were in service. The Jordanian Army used its Centurion tanks in the Six-Day War. In 1967, the 10th Independent Tank Regiment was equipped with 44 Centurion Mk.V tanks armed with 20pdr guns, but was initially deployed on East Bank. Later, the unit was moved urgently to the Hebron area, in West Bank, in order to link with the supposed Egyptian advance. Some Centurion tanks were destroyed and about 30 captured by the Israeli Army. Israelis entering Hebron captured 25 Jordanian Centurion tanks. The Royal Guards Brigade had one regiment that was also equipped with Centurions.

After the 1967 war, the army was rearmed and more Centurion tanks were purchased.

In September 1970 (Black September) Jordan used Centurions of the 40th Armoured Brigade against invading Syrian T-55 tanks. Jordan lost 75 to 90 tanks out of 200 involved.[67] Most of them were destroyed by Syrian tank fire at ar-Ramtha.[68] But some of them were destroyed by the PLO in Amman.[69] Palestinians used captured Centurion tanks against the Jordanian army.[70]

In 1972, Centurion tanks were reequipped with 105 mm guns. During the Yom Kippur War, the Jordanian 40th Armoured Brigade was deployed in the Golan front to support Syrian troops and show King Hussein's concern for Arab solidarity. The 40th Armoured Brigade moved northward towards Sheikh Meskin, but its counterattack was uncoordinated and largely ineffective as the Israelis were in prepared defensive positions.

In 1982–1985, 293 surviving Centurions of the Jordanian Army were refitted with the diesel engine and transmission of the M60A1 tank in place of the original Meteor petrol engine, Belgian SABCA computerised fire-control system, which incorporated a laser range-finder and passive night sight for the gunner, Cadillac Gage electro-hydraulic turret drive and stabilisation system and a new Teledyne Continental hydropneumatic suspension in place of the Horstmann units. These upgraded vehicles were called the Tariq. After retirement from service with the arrival of ex-British Challenger tanks in the late 1990s, several Tariqs were converted into heavy APCs.

Modified South African Centurion Mk 5

South Africa ordered 203 Centurion Mk 3 tanks from the United Kingdom in 1953.[71] The South African Centurions entered service between 1955 and 1958, and included about 17 armoured recovery vehicles.[71] South Africa's major strategic priorities at the time revolved around assisting the British Armed Forces and other member states of the Commonwealth of Nations during a conventional war in the Middle East or Anglophone Africa.[72] The Centurions were procured specifically because they were compatible with Commonwealth tank tactics and preexisting British armoured formations.[73]

Following South Africa's withdrawal from the Commonwealth in 1961, its priorities shifted toward internal security and diversifying national arms procurement outside traditional suppliers such as the United Kingdom.[73] To that end, 100 Centurion Mk 3s and 10 Centurion-based recovery vehicles were sold off to Switzerland in 1961.[71] The remaining Centurions were largely relegated to reserve roles as a result of maintenance problems compounded by parts shortages and a tendency to overheat in the hot African climate.[73][74] In 1972, the South African Army retrofitted some of its Centurions with the engines and transmission of American-made M48 Patton tanks in an attempt to improve technical performance.[75] The upgraded Centurions were designated Skoikaan and proved unpopular due to their high fuel consumption and poor operating range.[74]

The first Skokiaan prototype

Tanks reentered the mainstream of South African military doctrine in 1975, following Operation Savannah, which saw the lightly armoured South African forces in Angola threatened by large formations of Soviet tanks supplied to the People's Armed Forces for the Liberation of Angola (FAPLA) and their Cuban allies.[73] Operation Savannah was followed by further modifications and trials under Project Semel, and the South African government was obliged to finance the creation of a new private sector enterprise, the Olifant Manufacturing Company (OMC), to refurbish the Centurions.[73] During this period South Africa managed to restore its tank fleet to its original size by purchasing a number of surplus Centurion hulls from Jordan and India.[75] The passage of United Nations Security Council Resolution 418, which imposed a mandatory arms embargo on the country, forced South Africa to purchase the hulls without turrets or armament.[71] OMC upgraded each Centurion with a 29-litre Continental turbocharged diesel engine and a new transmission adopted from the M60 Patton.[75] The refurbished Centurions were also armed with a South African variant of the Royal Ordnance L7 105 mm main gun.[75] They were accepted into service with the South African Armoured Corps as the Olifant Mk1A in 1985.[75]

South African expeditionary forces clashed with FAPLA T-54/55 tanks during Operation Askari in late 1983 and early 1984; however, due to the enormous logistical commitment needed to keep the Olifants operational so far from conventional repair facilities, they were not deployed.[73] At length the South African mechanised infantry, bolstered by Eland and Ratel-90 armoured car squadrons, succeeded in destroying the tanks on their own, although severe delays were encountered due to their lack of adequate anti-tank weaponry.[76] Morale also suffered when inexperienced armoured car crews were ordered to take on the Angolan T-54/55s in their vulnerable vehicles.[76] Criticism in this regard led to the deployment of a single squadron of thirteen Olifant Mk1As to the Angolan border, where they were attached to the 61 Mechanised Battalion Group.[76] Following the Lusaka Accords, which effectively ensured a ceasefire between South Africa and Angola, these Olifants were placed into storage and the tank crews rotated out.[76]

Olifant Mk2

The collapse of the Lusaka Accords and the subsequent launch of Operation Moduler in late 1987 led to the Olifant squadron being reactivated on the direct orders of South African State President P.W. Botha.[73] On 9 November 1987 the Olifants destroyed two Angolan T-55s during a heated nine-minute skirmish.[77] This marked the first occasion South African tanks had been sent into battle since World War II.[77] Throughout Operation Moduler, South African forces typically dispersed into an "arrowhead" formation, with Olifants in the lead, Ratel-90 armoured cars on the flanks, and the remainder of the mechanised infantry to the rear and centre.[78] Three Olifants were abandoned in a minefield during Operation Packer and subsequently captured by FAPLA, while another two were damaged beyond immediate repair by mines but successfully recovered.[79][80] A number of others suffered varying degrees of track and suspension damage due to mines or Angolan tank fire, but were able to keep moving after field repairs.[81]

In the early 1990s, the Olifant Mk1A was superseded by the Olifant Mk1B, which incorporated major improvements in armour protection, a slightly more powerful engine, a double armoured floor for protection against mines, and a torsion bar suspension.[75]

Swedish Centurion tank

At the end of the Second World War, it was clear that the mix of tanks in service with the Swedish Armed Forces was not just obsolete but also presented a large logistical problem. Kungliga Arméförvaltningens Tygavdelning (KAFT, the weapons bureau of the army administrative service) conducted a study that concluded that the most cost-effective alternative would be to purchase the newly developed Centurion Mk 3, which, while quite modern, was judged to also have upgrade potential for future requirements. A purchase request was sent to Great Britain, but the reply was that no deliveries could be made before the needs of the British Army had been satisfied, which was deemed to take between five and 15 years. Thus, in 1951, the vehicle bureau of KAFT was set to develop a Swedish alternative project, E M I L. Parallel with this, negotiations were initiated with France about buying the AMX-13.

The British stance altered in early December 1952, due to the economic necessity of increasing exports to earn scarce foreign currency. Britain offered to sell the desired Centurions immediately. Minister of Defence Torsten Nilsson arbitrarily placed an order of 80 Mk 3, with Swedish Army designation stridsvagn 81 (strv 81), around new year 1952/1953, with the first delivery in April 1953.[82][83][84] In 1955, Sweden ordered a batch of 160 Centurion Mk 5 (also designated strv 81), followed by a batch of 110 Centurion Mk 10 around 1960 (designated strv 101). The Centurions, together with the Stridsvagn 103, formed the backbone of the Swedish armoured brigades for several decades. The Mk 3 and the Mk 5 were upgraded with a 105 mm gun in the 1960s, becoming strv 102.

Between 1983 and 1987, the Centurions had a midlife renovation and modification (REMO) done, which included among other things night vision equipment, targeting systems, laser range finders, improved gun stabilisation, thermal sleeves on the barrel and exhaust pipes and reactive armour developed by the Swedish FFV Ordnance. Around 80 strv 102 were upgraded with Continental diesel engines and Allison gearboxes in the early 1980s, becoming strv 104.

The Swedish Army gradually phased out its Centurions and Strv 103 during the 1990s as a consequence of comparative tests of the T-72, Leclerc, M1A1 and Leopard 2. They were replaced with the Stridsvagn 121 and Stridsvagn 122.

The Atomic Tank at Robertson Barracks

An Australian Army Mk 3 Centurion Type K, Army Registration Number 169041, was involved in a small nuclear test at Emu Field in Australia in 1953 as part of Operation Totem 1. Built as number 39/190 at the Royal Ordnance Factory, Barnbow in 1951 it was assigned the British Army number 06 BA 16 and supplied to the Australian Commonwealth Government under Contract 2843 in 1952.[85]

It was placed less than 500 yards (460 m) from the 9.1 kt blast with its turret facing the epicentre, left with the engine running and a full ammunition load.[86] Examination after detonation found that it had been pushed away from the blast point by about 5 feet (1.5 m), pushed slightly left and that its engine had stopped working, but only because it had run out of fuel. Antennae were missing, lights and periscopes were heavily sandblasted, the cloth mantlet cover was incinerated, and the armoured side plates had been blown off and carried up to 200 yards (180 m) from the tank.[85] It could still be driven from the site. Had the tank been manned, the crew would most likely have been killed by the shock wave.

169041, subsequently nicknamed The Atomic Tank, was used in the Vietnam War. In May 1969, during a firefight, 169041 (call sign 24C) was hit by a rocket-propelled grenade (RPG). The turret crew were all wounded by fragmentation as the RPG hollow charge jet entered the lower left side of the fighting compartment, travelled diagonally across the floor and lodged in the rear right corner. Trooper Carter was evacuated, while the others remained on duty and the tank remained battleworthy.[86]

The Atomic Tank is now located at Robertson Barracks in Palmerston, Northern Territory. Although other tanks were subjected to nuclear tests, 169041 is the only one known to have withstood a blast and to have later fought in a war.[87]

Centurion Mk 5 NL and Mk 5/2 NL

Circa 1965, Dutch Mk 5 and 5/2 tanks were equipped with infrared headlights, searchlight, and viewing equipment, of Philips design instead of the types used on British tanks. Around the same time, a .50-caliber ranging machine gun was added, as was a spare wheel bracket on the rear of the turret, and from 1969, the M1919 Browning machine guns were replaced by FN MAGs. From 1973, the tanks' radio sets were replaced by Philips-designed ones.[97]

Olifant

Olifant tank

Centurion tanks redesigned and rebuilt by South Africa with the help of Israel; considered the best indigenous tank design on the African continent.

Tariq

Jordan designation.

• Israel Gun tanks retired, many hulls converted to Nagmachon APCs, Nakpadon ARVs or Puma CEVs.
• Jordan Chassis re-used for the modern Temsah APC[100]
• South Africa In service as the indigenously developed and upgraded Mk1A/B and Mk2 Olifant[101][102]

• Australia Replaced by Leopard 1.
• Austria Now fixed in bunkers.
• Canada Initially ordered 274 Mk 3 tanks, plus nine armoured recovery vehicles and four bridge-layers and additional orders followed. The Mk 5 (upgunned to 105 mm) were used later. From 1969 to 1970, the Canadian Army lists 77 tanks based in Germany (mostly Mk 5 and Mk 11's) and the remainder in Canada (60 at CFB Wainwright AB, 59 at CFSD Longue-Pointe QC, 46 at CFB Gagetown NB, 30 at CFB Borden, 29 at CFB Meaford ON, 27 at CFB Calgary AB, 12 at CFB Petawawa ON, six at RCEME School Kingston ON and one at the LETE Test Establishment Orleans, CFB Ottawa ON) for a total of 347 tanks (including 120 Mk 5s, three Mk 5 recovery tanks and some Mk 11s with IR and ranging guns fitted). Replaced by Leopard C1. Many of the tanks were sold to Israel, which converted them to diesel. Some are still in use as variants.
• Denmark Replaced by Leopard 1.
• Egypt Replaced by T-55s, T-62s, M60A3s and M1A1s.
• India Retired
• Iraq Retired
• Kuwait, handed over to Somalia circa 1977
• Lebanon
• Netherlands Initially received 435 Mk 3 tanks beginning in 1953, increased to 592 by 1956; all were paid for by the United States as part of the Mutual Defense Assistance Act. As one was lost to an accidental fire in 1953, 591 gun tanks were on strength, and were soon upgraded to Mk 5 standard with 20-pounder gun and the British radio sets replaced by American types; one fuel mono-trailer was also available per tank. From 1956 to 1958, 66 ARV Mk 2s were procured, and in 1959–60, 70 Mk 7 tanks were delivered from the UK; these were all held in war reserve until 1969, when they were disposed of. Over the years 1960–72, 343 Mk 5 tanks were gradually upgunned with 105 mm guns to Mk 5/2 standard, as were 19 Mk 7s (to Mk 7/2) in 1966–68. Between 1962 and 1965, 17 Mk 5 tanks were converted to bridge layers, using the same bridge and mechanism as the American M48 and M60 AVLBs; at the same time, another 17 Mk 5s with 20-pounder guns were converted to dozer tanks. As an experiment, one Mk 5/2 and one Mk 7/2 were converted by installing a diesel engine in 1968; though successful, it was not adopted because the cost approached that of buying a new Leopard 1. All Centurions were replaced by Leopard 2 MBTs in the 1980s, after having been used alongside Leopard 1s in the 1970s. Many Mk 5 and all Mk 7 tanks were returned to the United States (which had paid for them), which appears to have shipped most to Israel.[97]
• New Zealand 12 retired without replacement.
• Singapore 63 Centurion Mk3 and Mk7s bought from India in 1975 and more from Israel in 1993–1994, all upgraded to Israeli standard with new main guns and diesel engines[103] It has since been replaced by the Leopard 2SGs.
• Somalia – Christopher F. Foss, writing in the second edition of Jane's Main Battle Tanks said that 'Kuwait was believed to have supplied Somalia with about 35 Centurions.'[104] The Military Balance 1987–88 (p. 112) listed 30 Centurions held by the Somali Army.
