The South African Army’s Air Defence Artillery has ordered the procurement of spares and accessories for its Oerlikon GDF Mk 5 towed anti-aircraft guns.

The $446,898 order is a follow-on contract awarded to Intertechnic Contracting in February for support services for the 35mm system and 23mm ZU23-2 gun system.

The GDF had suffered a design flaw which killed nine soldiers during a gunnery exercise in October 2007.

The inspection found that ten of the Army’s 48 GDF systems had broken spring pins which led to the injury.
