BOL is a high capacity countermeasure dispenser for chaff or flares, giving pilots the sustained defensive capability needed to successfully accomplish missions.

Features

BOL’s high payload-to-volume ratio, non-pyrotechnic release mechanism and effective dispersion gives the dispenser superior performance for both chaff and IR payloads. The latter allows covert dispensing of a special material that has proved highly effective against advanced IR missiles.

IR payloads development

Covert infrared decoys have been greatly improved thanks to new IR materials and methods of tactical deployment. Break-lock from hostile tracking radar can be further facilitated by synchronising chaff dispensing with aircraft manoeuvres and the use of jammers.

High capacity

The ingenious design of BOL has revolutionised the dispensing of chaff and IR payloads. An elongated shape houses a long stack of payload packs (160). An electromechanical drive mechanism feeds the packs towards the aft of the dispenser where one pack at a time is separated from the stack and released into the airstream. The high-capacity of the dispensers gives pilots the sustained defensive capability needed to successfully accomplish missions.

Rapid dispersion

The BOL internal vortex generators (airscoops) and vortex fields behind the aircraft, used with the specially designed IR payloads, make the air-stream rapidly build up a large radiating IR decoy cloud.

With dispensers on each wing, the spatial separation of payload clouds significantly increases radar cross-section (if used with chaff) or the extension of the IR radiating source (if used with IR payload). BOL systems are thus usually mounted in a symmetrical twin or quadruple configuration on the wings.

Easy to install

BOL offers numerous installation alternatives for new aircraft and for retrofits. It is currently operational on several different fighter aircraft, and interest for transport and bomber aircraft is growing significantly. The elongated shape of BOL lends itself to installation in elongated cavities in the aircraft structure, missile launchers and pylons.

Installation has been achieved without interfering with weapon load or flight performance. BOL has been successfully integrated with a range of missile launchers including the LAU-7 Sidewinder launcher, the LAU-127/128/129 family of AMRAAM launchers, and the CRL and MPRL launchers.

Several dispenser control options

The BOL interface includes a choice of digital data links as well as 28 V discretes. This makes BOL suitable for incorporation in highly integrated defensive aids systems as well as traditional countermeasures systems.

In use

An international alliance has been formed by Saab (Sweden), BAE Systems (USA), Chemring Countermeasures (UK) and Alloy Surfaces (USA) to pursue worldwide opportunities for this innovative and unique dispenser system. As a customer, you will benefit from this through our broad and total system integration and CM operation knowledge and experience.
