Apache AH-64REs to be fitted with Leonardo DAS
Leonardo has been contracted by the UK Ministry of Defence (MOD) to provide a defensive aids suite (DAS) for the British Army's new fleet of Apache AH-64E helicopters.
Under related contracts from the UK MOD and Boeing, Leonardo will integrate sensors and countermeasures to ensure that UK Apaches remain amongst the best protected attack helicopters in the world.
Combat helicopters such as the Apache fly at relatively low speeds compared to fighter jets and often at low altitudes, so they are vulnerable to a wide range of threats including infrared-guided missiles and anti-tank guided weapons. An integrated defensive aids suite helps protect a helicopter from threats in a joined-up way. A complete system includes sensors to identify threats to the helicopter, countermeasures to defeat these threats and a computer that coordinates the whole system, linking the incoming warnings with protection techniques such as chaff or flares.
Every Apache AH-64E that comes off the production line, regardless of its end user, already has a built-in Leonardo defensive aids suite computer, known as an 'AGP' (Aircraft Gateway Processor). This project will see Leonardo take the UK's Apache defensive aids suite a step further by integrating a number of sensors and countermeasure systems onto the AH-64E to enhance its situational awareness and survivability.
The helicopters' sensor fit will include Leonardo's SG200-D radar warning receiver (the UK-specific variant of the company's SEER family) and will re-use a number of systems that are currently on-board the Army's fleet of Apache AH Mk1. These re-used sensors and effectors include Leonardo's S1223 laser warning receiver, the BAE Systems AN/AAR-57 missile approach warner and the Thales Vicon countermeasure dispensing system. Initially these systems will be taken from spares stores and the remainder will become available when the AH Mk1s retire from service in 2023/24.
