The G6, sometimes denoted as the G6 Rhino,[6] is a South African self-propelledhowitzer.[7] It was developed as a turreted, self-propelled variant of the G5 howitzer series, mating the gun to a six-wheeled mine-protected armoured chassis.[8] 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.[9] Serial production commenced between 1988 and 1999.[4]
At the time of its introduction, the G6 was considered one of the most mobile self-propelled howitzers in service.[10] Its chassis was engineered to be mine-resistant and blastproof, allowing it to survive multiple TM-46 detonations during trials.[11] The G6 was conceived as a wheeled rather than a tracked vehicle for this purpose, as well as to allow it to deploy long distances by road without consuming excessive quantities of fuel or requiring a tank transporter.[11]
Chile briefly produced the G6 under licence as the CC-SP-45, although this arrangement was later terminated after the system was not adopted by that country's armed forces.[4]Iraq also manufactured its own domestic variant of the G6[16] as the Al Majnoon with technical assistance from Canadian artillery engineer Gerald Bull, which later evolved into the much larger and more sophisticated Al Fao.[17]
can fire projectile up to 67 km at a rate of fire of eight rounds/minute;
increased off-road speeds to nearly 70 km/h;
implemented multiple rounds simultaneous impact (MRSI) technology and can land six (G6-52L variant) or five (G6-52) rounds simultaneously at targets up to 25 km away.
G6 Marksman: a British SPAAG version, combining the G6's base vehicle with the Marksman turret.[20]
The first G6 prototype appeared in 1981, during the height of the South African Border War.[2] Four engineering development models were being tested with the South African Defence Force by the mid-1980s.[2] In October 1987, the South African government ordered all the G6s deployed to Angola for combat trials as part of Operation Hooper.[12] One suffered an engine failure, so only three actually reached Angola, where they joined expeditionary troops of the 4 South African Infantry Battalion.[2] Operating as an independent battery, the three G6s were instrumental in the bombardment of the strategic Angolan airfield at Cuito Cuanavale.[12] In this their crews were significantly aided by South African special forces acting as forward artillery observers near the airfield; on one occasion the G6s were able to destroy four Angolan Mikoyan-Gurevich MiG-21s on the ground as they attempted to take off.[8]
The heightened artillery threat to the Cuito Cuanavale airfield eventually forced the Angolan pilots to relocate their operations to another airstrip at Menongue, which was beyond the range of the G5 and G6 but severely diminished their ability to time and execute their missions, given Menongue's distance from the actual fighting.[12] However, they also began making South African artillery positions the primary targets of their raids, forcing the G6 crews to constantly shift positions after each bombardment.[2] The G6s themselves were considered so valuable that an air defence contingent from South Africa's 10 Anti-Aircraft Regiment was subsequently attached to the battery for the remainder of the campaign.[2]
The G6 is not known to have seen combat again until 2015, when a single battery was deployed with the United Arab Emirates Defence Force to Aden during the Yemeni Crisis.[24] The howitzers were landed in Aden by ship and escorted by a large Emirati armoured formation.[24] They have since been used to shell Houthi militant positions in support of Emirati and allied Yemeni offensives carried out near Taiz.[25]
