Atlas Oryx - Variants

Variants

In its basic platform the design of the Oryx offers a number of advantages and this was further developed from an early stage in the program. With the Rooivalk now in service, this combat helicopter will escort the Oryx in a high threat environment. However, as an interim measure an Oryx with door mounted machine guns did appear. Oryx helicopters are constantly refined and updated. A full glass cockpit is planned for a future update. The latest addition is the fitting of flare dispensers and the update of the Threat Warning Receivers.

There is an electronic warfare (stand-off communications jamming/radar jamming) version of the Oryx that is equipped with the Grinaker Systems Technologies (GST) GSY 1501 jamming system, among others. The first Oryx variant with a large log periodic antenna on the starboard side was regarded as quite an effective EW platform. This platform is capable of disrupting key communications during various stages of modern, air-, land-, and sea battles. In addition it is used as an effective training aid to the SANDF, to test their function as an effective fighting force, despite any EW methods employed against the SA Forces. A further advantage is, EW equipment in use by the SA Forces can be effectively evaluated and calibrated under simulated battlefield scenarios. One variant has its main cabin doors replaced by dome shaped antennas.

The Oryx Mk. 2 contains such a number of differences, that a different model number is used, to distinguish the type. Although, operated and flown by 22 Squadron SAAF, these helicopters were specifically build for use by the Department of Environmental Affairs and Tourism, as part of the South African National Antarctic Programme. Two Oryx helicopters have been modified for operations in the Southern Ocean and the Antarctic, for which they have been painted in the red and white colour scheme. Highly effective, de-icing equipment, of up rated specification, was the central requirement of the Mk. 2 program. The project received the go-ahead on 15 March 1996, with Lt Col K. Viljoen as project leader. The project was completed three weeks ahead of schedule and the two helicopters delivered to 22 Sqdn, during October 1997. One of the Mk. 2 Oryx helicopters was written off subsequent to a crash landing in July 2004.
