The BAE Systems Mark 36 Super Rapid Bloom Offboard Countermeasures Chaff and Decoy Launching System (abbreviated as SRBOC or "Super-arboc") is an American short-range decoy launching system (DLS) that launches radar or infrared decoys from naval vessels to foil incoming anti-ship missiles . The decoys present false signals and interference to the attacking missiles' guidance and fire-control systems.
7-551: The Mark 36 SRBOC uses the Mark 137 launcher, which has six fixed 130 mm mortar tubes arranged in two parallel rows. One row is set at 45 degrees and the other is set at 60 degrees, providing a spread of the launched decoys. Firing circuits use electromagnetic induction to set off the propelling charges in the decoy cartridges. They are launched at a speed of 75 m/s. Each launcher holds 12–36 rounds, depending on variant. The number and arrangement of Mk 36 launchers installed depends on
14-469: A drone that was of conventional configuration, having a low-mounted, folding wing and a cruciform tail section; an electric motor was mounted in the nose of the aircraft. Launch was via a rocket booster , providing 1.6 seconds of thrust, from the Mark 137 launcher of the Mark 36 SRBOC system; the use of the Mark 36 launcher put a constraint on the possible size of the drone, which was designed to compact into
21-403: A package the size of a standard NATO Mark 36 chaff rocket. The tail fins would unfold immediately on launch, while the wing would deploy and motor start after burnout as the aircraft coasted to the apogee of a ballistic trajectory. The expendable Flyrt carried a radio repeater with two antennae for spoofing enemy radar signals. Following a series of ballistic tests to verify compatibility of
28-510: Is similar to the Sea Gnat decoy system. The decoy launching system consists of: The Mark 36 can be equipped with and fire the following decoys: Table reference: As of 2010, over 1,000 Mark 36 SRBOC systems are in use by the fleets of at least 19 countries, including: Naval Research Laboratory Flyrt The Naval Research Laboratory Flyrt , or Flying Radar Target , was a small electric-powered unmanned aerial vehicle developed by
35-591: The United States Naval Research Laboratory to serve as an expendable radar decoy for the defense of United States Navy ships. Tested in the fall of 1993, it was considered successful but was not ordered into production. Begun in 1991, the Flyrt program was intended to produce an expendable decoy drone , not requiring any new aboardship infrastructure, for the defense of warships against radar-guided antiship missiles. It produced
42-528: The Mark 36 SRBOC, redesignated as the Mark 53 decoy launching system, was created to use the newer Nulka active radar decoy. Nulka hovers in the air and emits radiofrequency energy to lure the seekers of anti-ship missiles. The Mark 36 is interfaced with the AN/SLQ-32 electronic warfare suite . The SLQ-32 (with the exception of the (V)4 variant) can automatically fire decoys from the Mark 36 SRBOCs when it detects an anti-ship missile attack. The Mark 36 SRBOC
49-466: The size of the ship, ranging from two launchers on a small combatant to as many as eight on an aircraft carrier. To complement conventional ballistic decoys, the FLYRT (FLYing Radar Target) decoy had been developed in the 1990s. It had rocket propulsion and flew at a ship-like speed in an attempt to present itself as a surface target. However, FLYRT did not undergo production. Instead, a modified version of
