In the late 1970s, South Africa was involved in an international controversy over apartheid and the South African Border War in Angola. As a result, it was subject to an international arms embargo and had to, out of necessity, design and manufacture its own weapons.[1] The SS-77 was developed to replace the FN MAG. It was designed in 1977 by Col. Richard Joseph "Boer" Smith and Lazlo Soregi. The "SS" in its name stands for Smith and Soregi, and "77" for 1977, the year it was designed.[1] The design was put into action and the prototype components were hand manufactured in the armoury shop of 61 BWS under the supervision of Sgt Hattingh, L/cpl Nel and two privates. When said components worked well in the prototype, it was handed over to Lyttleton Engineering, who eventually manufactured and brought the SS77 into production.
Denel unveiled at the Africa Aerospace and Defence (AAD) 2016 exhibit that the SS-77 will be replaced in production by the DMG-5 and DMG-5 CX GPMG.[2]
SS-77s typically feed ammunition using an R1M1 disintegrating link belt, though M13 disintegrating link belts and non-disintegrating DM1 belts are also compatible. The belt may also be further contained in a dust-proof nylon pouch with a 100-round capacity, or a waterproof and rigid box with a 200-round capacity.[citation needed]
Mini-SS
In 1994, a light machine gun version, the Mini-SS, chambered in 5.56×45mm NATO was introduced. LIW also manufactured kits to convert existing SS-77 to the Mini-SS. Changes include the weight decrease from 9.6 to 8.26 kg (21 lb 3 oz to 18 lb 3 oz) with a folding bipod and fixed butt.[3]
