Saab will offer its Giraffe 4/8A radars to meet the South African Air Force’s (SAAF’s) Project Chutney requirements for the replacement of its ground based radars.
Derik van Heerden, Marketing Executive: Air at Saab Grintek Defence told defenceWeb that Saab has answered the Request For Information (RFI) for Project CHUTNEY, but is awaiting the release of the Request for Offer (RFO) from Armscor. The RFO is expected during the first quarter of 2016.
Van Heerden said the Giraffe 4/8A would meet the SAAF’s requirements as it can give high situational awareness through simultaneous air surveillance and ground based air defence system (GBADS) target acquisition together with weapon locating capacity. All this functionality is available in the Giraffe 4A, which is a complete multi-role radar especially for deployments in a peace keeping role, Saab said. In weapon locating mode, the radar searches the horizon and tracks incoming projectiles, calculating the point of origin and point of impact, providing a sense and warn function.
According to Saab literature, much emphasis has been put on the Giraffe 4A’s electronic counter-countermeasures (ECCM) performance and the radar features ultra-low side lobes, frequency agility, pulse repetition frequency (PRF) switching and stagger, jammer detection etc.
The Giraffe 4A is an active electronically scanned array(AESA) radar in S (E/F) band utilising the latest Gallium Nitride (GaN) technology. Range in air surveillance mode is 280 km and weapon locating mode 100 km. It can monitor more than 1 000 aircraft tracks, and over 100 weapon tracks a minute.
The Giraffe 4A can be deployed by two people in less than ten minutes and taken down in five. It can be transported by a single C-130.
Other ground-based radars in the Saab ground base portfolio include the Giraffe 1X, Arthur weapon locating radar, Giraffe AMB and long range Giraffe 8A. These cover air surveillance, ground-based air defence, weapon locating, sense and warn and multi-role capabilities. The Giraffe 4A is the only radar in Saab’s lineup that does all these in one.
Saab has already secured orders for the new Giraffe 4A.
One of the types to be replaced under CHUTNEY is the mobile three-dimensional Plessey AR3D “Umlindi” air defence radar system. The SAAF operates six of these units.
Saab has previously demonstrated its Griaffe radar to the South African National Defence Force, notably during Exercise Good Hope III in 2008.
