Американская система постановки ложных целей ближнего радиуса действия Mark 36 SRBOC

American short range decoy launching system

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.

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. Each launcher holds 12–36 rounds, depending on variant. The number and arrangement of Mk 36 launchers installed depends on the size of the ship, ranging from two launchers on a small combatant to as many as eight on an aircraft carrier. 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 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 is similar to the Sea Gnat decoy system.
