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.

[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.

[citation needed] In 1994, a light machine gun version, the Mini-SS, chambered in 5.56×45mm NATO was introduced.
