Encyclopedia - Denel AH-2 Rooivalk

With the SANDF initial requirement for 12 aircraft largely satisfied, the Rooivalk fleet is now able to perform its intended role of providing real and affordable deterrence value and to defend South Africa and its citizens.

Despite being a highly mobile, fast reaction airborne mission leader, Rooivalk is equipped with a full armoury compliment, which includes the South African 8000m range Mokopa anti-tank missile, where it will be a defender that any enemy would not wish to engage.

Rapid air support can be provided to our own troops, where Rooivalk can act as a force multiplier in peacekeeping and peace enforcement roles.

Army Commanders require accurate real time reconnaissance capability, for which Rooivalk is ideally suited. With its connection to sensors and communication links across the operational area, Rooivalk is the key intelligence link in command and control. This provides the entire operation with real time shared intelligence, potentially lowering the risk of friendly fire and collateral damage.

This feature, along with its inherent firepower abilities and unique flyability, makes Rooivalk an essential component in any operation.

The design of a modern Attack Helicopter has to include a multitude of requirements. Rooivalk is an integral part of the total defence network - fully autonomous, flexible, mobile and providing fire power 24/7, while maintaining user friendly interfaces to all command and control structures.

TACTICAL EMPLOYMENT

Rooivalk on Armed Reconnaissance:

  • Reconnoitre and locate threats with long-range on-board sensors
  • Secure flanks or weak areas with fast response times
  • Coordinate with joint operations teams
  • Select attack routes and positions, irrespective of the terrain
  • Provide surveillance and early warning of threats
  • Enhancement of C3I

Rooivalk on Tactical Missions:

  • Find the enemy and avoid detection
  • Provide the Battlefield Commander with:
    • 3-Dimensional situational awareness
    • Real time Data
    • Friend or foe discrimination
  • Be able to operate in close, deep or rear battle
  • Be able to operate with minimal logistics burden out of unprepared areas

Rooivalk on specific missions:

  • Targets are acquired first to ensure that Rooivalk fires first, based on accurate situational awareness
  • Enemy armour or mechanised forces can be destroyed using the Mokopa anti-armour missile
  • Enemy air defences are suppressed or destroyed using the precision weapon Mokopa
  • Enemy's second echelon is disrupted and/or destroyed using rockets in indirect mode
  • Rapid rear area protection can be provided with quick re-deployment and hot turnarounds as required.

FULL SITUATIONAL AWARENESS

Defence Force Commanders gain a true 24-hour real-time tactical situational awareness in all weathers from Rooivalk's multi-spectral sighting systems. Reconnaissance and targeting capability is possible using the nose-mounted main sight (LLTV, FLIR) and the helmet-mounted sighting display (3rd generation NVG).

Rooivalk's fully integrated digital management system and low cockpit workload provides crew with more time for battlefield awareness.

VERSATILITY OF DEPLOYMENT

Rooivalk's design allows a long-range self-deployment capability of over 1 100km, longer if refuelling stops are included, or it can be deployed with minimal knockdown in a Hercules C130. Rooivalk can be deployed into the field without support, with a substantial standby operational period. Full autonomous re-arm and refuel can be carried out in the field with minimal support.

SURVIVING THE BATTLEFIELD

Rooivalk has unprecedented high levels of survivability through a systematic redundant design approach which combines extended lethal reach, rapid engagement times and agility with low detectability, comprehensive defensive aids, self-defence weapons and unmatched ballistic tolerance and crashworthiness.

Rooivalk operates exclusively at nap-of-the-earth heights and is capable of flight in adverse weather conditions and combines low audio, visual and infrared signatures to avoid detection.

MATCHLESS WEAPONS

Up to 16 Mokopa missiles - the most accurate and lethal new generation anti-armour and point target missiles available - can be carried, able to engage static and moving targets at ranges in excess of 8000m, observed and tracked with the onboard sighting systems or from a remote observation post. Up to 76 free-flight rockets can be fitted with a variety of warheads for area suppression.

Up to 4 Mistral air-to-air missiles can be carried for air defence and anti-helicopter roles, and a 20mm cannon for self-defence (slaved to the helmet sight for quick response). The cannon can also be used, slaved to the main sight, to provide an effective and accurate point weapon.
