Aircraft and helicopters remain vulnerable to air defence systems, especially man-portable variants. Israel’s BIRD Aerosystems (Hall 6, Stand C353) is showing its new directional infrared countermeasure (DIRCM) system here.
Called SPREOS (self-protection radar electro-optic system) and jointly developed with a large European firm, this solution is ideal for a wide range of airborne platforms, from small helicopters to large transport aircraft. It combines a radar-based sensor for verification purposes and an active laser to provide enhanced protection against the immediate threat of man-portable air defence systems (MANPADS).
SPREOS integrates into a single line replaceable unit with multiple functions, including threat confirmation, tracking and jamming of advanced IR guided missiles.
A warning from the onboard missile warning system (MWS) triggers SPREOS to slew to the direction of the incoming threat. The dual-band radar function activates for confirmation and high-precision tracking. SPREOS then deploys the dual-band countermeasure laser, causing the missile to miss the aircraft.
BIRD Aerosystems is renowned for airborne missile protection systems (AMPSs) and airborne surveillance, information and observation (ASIO) solutions, which are operational in NATO forces, UN air operations and with many other customers worldwide.
