Operation Alpha Centauri (1986) was a military operation by the South African Defence Force during the South African Border War and Angolan Civil War.
This aim of this operation was to stop a FAPLA advance on the UNITA "capital" of Jamba; this was achieved in and around the Angolan town of Cuito Cuanavale.
The G5 howitzer was used operationally for the first time by the SADF on 9 August 1986 during Operation Alpha Centauri. This operation lasted until 16 August 1986. One battery of G5s (a battery consists of eight guns) was employed in conjunction with one battery of multiple rocket launchers (MRL). The operation was an artillery attack against Cuban and FAPLA formations concentrating in Cuito Cuanavale for their 1986 offensive against UNITA. The 25th Cuban-FAPLA Brigade was situated east of Cuito Cuanavale near Tumpo. The 13th Brigade was situated in Cuito Cuanavale and the 8th Brigade operated between Menongue and Cuito Cuanavale, the former being a large logistics depot. Convoys regularly travelled from Menongue to supply Cuito Cuanavale.
In the weeks before the first assault, the 8 G5's were flown in darkness from Rundu to Mavinga (15°47'36 S 20°21'49 E) over 2 nights by South African Air Force Lockheed C-130 Hercules aircraft, whilst the remainder of the battery including the gun-tractors drove the distance. The heavy guns were difficult to drag through the sandy terrain and this avoided a significant part of the journey from the border to the target area.
The G5 assault began at last light, about 17h10. It was time for dinner, and the first shots were fired after most of the Brigade at Cuito Cuanavale went into the mess for supper. By 23:00 the back of the opposition was broken. Heavy fire was brought down upon the enemy in the first five hours resulting in large scale destruction. The G-5's fired little during daytime, only when observation posts gave the OK.
The G-5 battery, aka Quebec Battery, didn't move for the first three days, while they were shooting.This was a first for any artillery movement. Normally, after the guns fired, they would pack up and move, to avoid being fired upon.
It took the battery of G-5's 3 days to break the offensive. Unita was left at Cuito Cuanavale,to keep control, and the battery of G-5's was already retreating, when the had to turn around and go back, as Unita got chased out of Cuito Cuanavale by re-enforcements of Cuban and FAPLA. The battery of G-5's then started another full-scale attack, taking out the re-enforcements as well. The battery of G-5's then blew up a landing strip the offense used as an attack platform for their Migs, and an ammo-base, which exploded for hours, and burned for 2-3 days.
This destroyed the 1986 Cuban and FAPLA offensive against UNITA and showed the tremendous destructive force that lay within one battery of G5s. Owing to the long range and the accuracy with which the G5 could fire and the effect of the ammunition, authority was forced upon the enemy.
The battery of G-5's became known as the Ghost-Battery, because they couldn't be found by the opposition. As a result of the daylight activities of the MiG-23 jet fighters employed by the Cubans, artillery fire missions could only be executed at night. As it was the first time that the G5 was used operationally there was great cause for concern that the MiGs would spot the G5s. The spotter planes went over the G-5 battery everyday, but it must have looked like a dummy shelter. The MiGs were continuously in the air trying to locate the G5s and bombed the surrounding area at random in the hope of hitting the artillery.
The closest the bombs ever got to the battery of G-5's, was to hit the shelter the G-5's stayed at for 3 days, only 2 hours after the G-5's moved to a new shelter.The battery of G-5's battled for weeks to retreat out of Angola, because of Migs, and spotter planes, being in the air all the time.
This operation proved to the SADF that survival was possible despite an unfavourable air situation. As a result of the enemy's air superiority, great attention was given to passive defensive measures such as camouflage, track discipline and the concealment of movement.
Special techniques of concealment were practised beforehand which prevented the enemy from observing the artillery. Before the operation was undertaken these techniques of concealment were also tested under conditions similar to those that the artillery would experience during the operation. Another factor in favour of the artillery was the unprofessional manner in which the enemy employed its air force. The MiG fighters mostly flew at very high altitudes, making observation very difficult for the pilots. The apparent reason for this was to avoid being shot down by UNITA's Stinger anti-aircraft missiles. In addition, the many bush fires in the area, owing to the dryness of the season, created a lot of dust and smoke in the air. During this operation approximately 2 500 multiple rocket launcher projectiles and approximately 4 500 G5 projectiles were used.
