The BAE Systems Mark 36 Super Rapid Bloom Offboard Countermeasures Chaff and Decoy Launching System (abbreviated as SRBOC or "Super-arboc") is a short-range mortar that launches chaff or infrared decoys from naval vessels to foil anti-ship missiles. Each launcher has three tubes set at a 45-degree angle, and three tubes set at a 60 degree angle, providing an effective spread of decoys and countermeasures to defeat radio frequency emitting missiles. The SRBOC can also be fitted with the TORCH infrared "flare" decoy system. A typical ship's load is 20 to 35 rounds per launcher.[citation needed]
As of 2010, the Mark 36 SRBOC is used by 19 navies around the world. It is similar to the NATO Sea Gnat system.[citation needed][needs update]
The Flyrt radar-decoy drone was designed to be launched from the Mark 36 launcher.[citation needed]
