The Vektor SS-77 is a general-purpose machine gun designed and manufactured by Denel Land Systems—formerly Lyttleton Engineering Works (LIW)—of South Africa.


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 Richard Joseph Smith and Lazlo Soregi, hence the name "SS-77". "SS" for Smith and Soregi, "77" for 1977, the year it was designed.[1]


In the early 1990s, 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.[2]
