The Elephant (Afrikaans: Olifant) is the primary main battle tank of South Africa. It was developed from the British Centurion tank since 1976. These tanks were heavily redesigned and rebuilt by South Africa since 1976 with some help from Israel. The Olifant is considered the best indigenous tank design on the African continent. Although based on a Centurion tank hull, it has a locally produced gun, power pack, transmission, tracks, wheels and fire control system and thus, at least the Olifant Mk.2 can be seen as almost a new tank.

History

The British Centurion tanks were the South African main battle tanks since 1957, but they were sold or relegated to reserve roles as a result of maintenance problems compounded by parts shortages and a tendency to overheat in the hot African climate. [2]

Thus, the Operation Savannah in 1975 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. [3] Operation Savannah led to the need of further tank trials under Project Semel. South Africa purchased a number of surplus Centurion hulls from Jordan and India, [4] but the United Nations Security Council Resolution 418, which imposed a mandatory arms embargo on the country, forced South Africa to purchase them without turrets or armament. [2]

The South African government was obliged by the arms embargo to finance the creation of a new private sector enterprise, the Olifant Manufacturing Company (OMC), to refurbish the Centurions. The Semel program in 1974 counted a total of 35 conversions, soon used operationally. Informations from the Sho't program, the Israeli Centurion conversion program, helped greatly to start a more ambitious project. These refurbished tanks were named Olifant Mk.1. [3]

During Operation Askari South African forces clashed with FAPLA T-54/55 tanks in late 1983 and early 1984; however, due to the respective logistical commitment the Olifants were not deployed. [3] At length the South African mechanised infantry, bolstered by Eland and Ratel-90 armoured car squadrons, succeeded in destroying the Angolan tanks on their own. [5] But eventually, a single squadron of thirteen Olifant Mk.1As was sent to the Angolan border, where they were attached to the 61 Mechanised Battalion Group. Following the Lusaka Accords, which effectively ensured a ceasefire between South Africa and Angola, the Olifants Mk.1 were placed into storage and the tank crews rotated out. [5]

Starting in 1983, OMC had upgraded further Centurions with a 29-litre Teledyne Continental turbocharged diesel engine and a new transmission adopted from the M60 Patton. The refurbished Centurions were armed with a South African variant of the 105 mm L7 rifled main gun. They were accepted into service with the South African Armoured Corps as the Olifant Mk.1A in 1985. [4]

The launch of Operation Moduler, following the collapse of the Lusaka Accords in late 1987, led to the Olifant squadron being activated on the direct orders of President P.W. Botha. [3] On 9 November 1987 the Olifants destroyed two Angolan T-55s. [6] Throughout the operation, 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. [7]

Three Olifants were abandoned in a minefield during Operation Packer from March to April 1988; one was retrieved by the Cubans and taken to the town of Cuito Cuanavale [8] : 338  and the other two remain to this day in the Angolan bush. [9] Another two were damaged beyond immediate repair by mines but successfully recovered. [10] 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. [11] The operational failure by the SADF ended in a strategic stalemate.

In the early 1990s, the Olifant Mk.1A was superseded by the Olifant Mk.1B, 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. It is barely recognisable as a Centurion. [12]

The Olifant Mk.2 was adapted in 2005 when South Africa was no longer subject to international embargoes. Externally, the Mk.2 looks identical to the Mk.1B but features an upgraded Continental 29 Litre turbo-charged V12 diesel engine that produces 1040 hp. Improvements include an upgraded Fire Control System (FCS) and a Computerised Battle System (CBS) which includes a hunter-killer mode. A LIW 120 mm smoothbore gun can be used instead of the 105 mm L7 rifled gun. In 2018, a total number of 26 Mk.2 tanks was produced. [13]

The T-54 and T-55 tanks are a series of Soviet main battle tanks introduced in the years following the Second World War. The first T-54 prototype was completed at Nizhny Tagil by the end of 1945. From the late 1950s, the T-54 eventually became the main tank for armoured units of the Soviet Army, armies of the Warsaw Pact countries, and many others. T-54s and T-55s have been involved in many of the world's armed conflicts since their introduction in the second half of the 20th century.

The G6, sometimes denoted as the G6 Rhino, is a South African mine-protected self-propelled howitzer. It was developed as a turreted, self-propelled variant of the G5 howitzer series, mating the gun to a six-wheeled armoured chassis. Design work on the G6 began in the late 1970s to replace the obsolescent Sexton being retired from service with the artillery regiments of the South African Army. Serial production commenced between 1988 and 1999.

Although lightly armoured, the vehicle's permanent 4X4 drive makes it faster over flat terrain than many tanks.

<span class="mw-page-title-main">Ratel IFV</span> Infantry fighting vehicle

The Ratel is a South African infantry fighting vehicle. It was the first wheeled infantry fighting vehicle to enter service worldwide and was built on a modified MAN truck chassis. The Ratel was designed in response to a South African Army specification for a light armoured vehicle suited to the demands of rapid offensives, providing maximum firepower and strategic mobility to mechanised infantry units intended to operate across the vast distances of Southern Africa. Primarily envisaged in SADF doctrine as a vehicle that could deliver mechanised infantry and supporting fire to tanks in conventional warfare, it was also anticipated that the Ratel could form the centrepiece for semi-independent battlegroups where logistics or politics precluded the use of tanks. The Ratel was a simple, economical design which helped reduce the significant logistical commitment necessary to keep heavier combat vehicles operational in undeveloped regions. It was generally regarded as an influential concept which incorporated a number of novel features, such as a mine-protected hull, an extended operating range of 1,000 kilometres, and a 20 mm autocannon fitted with what was then a unique twin-linked ammunition feed, allowing turret gunners to rapidly swap between ammunition types during combat.

The Battle of Cuito Cuanavale was fought intermittently between 14 August 1987 and 23 March 1988, south and east of the town of Cuito Cuanavale, Angola, by the People's Armed Forces for the Liberation of Angola (FAPLA) and Cuba against South Africa and the National Union for the Total Independence of Angola (UNITA) during the Angolan Civil War and South African Border War. The battle was the largest engagement of the Angolan conflict and the biggest conventional battle on the African continent since World War II. UNITA and its South African allies defeated a major FAPLA offensive towards Mavinga, preserving the former's control of southern Angola. They proceeded to launch a failed counteroffensive on FAPLA defensive positions around the Tumpo River east of Cuito Cuanavale.

<span class="mw-page-title-main">South African Border War</span> 1966–1990 border war between Zambia, Namibia, and Angola

The South African Border War, also known as the Namibian War of Independence, and sometimes denoted in South Africa as the Angolan Bush War, was a largely asymmetric conflict that occurred in Namibia, Zambia, and Angola from 26 August 1966 to 21 March 1990. It was fought between the South African Defence Force (SADF) and the People's Liberation Army of Namibia (PLAN), an armed wing of the South West African People's Organisation (SWAPO). The South African Border War was closely intertwined with the Angolan Civil War.

Operation Askari was a military operation during 1983 in Angola by the South African Defence Force (SADF) during the South African Border War.

Operation Displace was a military operation by the South African Defence Force during the South African Border War and Angolan Civil War. It involved maintaining the illusion that the SADF had remained in brigade strength east of Cuito Cuanavale at the end of April 1988 and the eventual withdrawal of all South African military units from south-eastern Angola during August 1988.

Operation Wallpaper was a military operation by the South African Defence Force (SADF) during the Angolan Civil War and South African Border War.

Operation Alpha Centauri was a South African military operation during the Angolan Civil War and South African Border War to halt an offensive launched by the People's Armed Forces of Liberation of Angola (FAPLA) towards Angola's Cuando Cubango Province. Its objective was to prevent FAPLA forces from reaching Jamba, a strategic town which functioned as the de facto headquarters of the National Union for the Total Independence of Angola (UNITA) and its armed wing.

Operation Moduler was a military operation by the South African Defence Force (SADF) during the South African Border War. It formed part of what has come to be called the Battle of Cuito Cuanavale. The Angolan objective was to advance south-east to attack the UNITA at Mavinga. The SADF objective was to protect UNITA by stopping that advance. The advance was halted with heavy Angolan casualties. The South African forces and its UNITA allies then began offensive operations against the Angolan forces, who had retreated back to a defensive line east of the Cuito River with the objective of destroying them once and for all.

Operation Packer was a military operation by the South African Defence Force (SADF) during the South African Border War and Angolan Civil War from March to April 1988. This operation forms part of what became known as the Battle of Cuito Cuanavale. Operation Packer was a continuation of Operation Hooper, using fresh troops and equipment. The Cubans' objective was still to secure the town of Cuito Cuanavale to the west of the river from capture. The SADF objective was once again to eliminate the remaining Angolan forces on the east side of the river, so as to ensure that the Angolans were no longer a threat to UNITA in the south-east. Although at the conclusion some Angolan units remained in positions east of the river, the Angolan advance against UNITA was permanently halted, and UNITA lived to fight on. The SADF never attempted to cross the river or to capture the town. Both sides again claimed victory.

Operation Prone was a proposed military operation by the South African Defence Force (SADF) and South West African Territorial Force (SWATF) during the South African Border War and Angolan Civil War between May and September 1988. With the advance of the 50th Cuban Division towards Calueque and the South-West Africa border, the SADF formed the 10 SA Division to counter this threat. The plan for Operation Prone had two phases. Operation Linger was to be a counterinsurgency phase and Operation Pact a conventional phase.
