The BO 105 CBS-5 Army or Navy is a lightweight twin-engine multi-role military helicopter. It is built by the EUROCOPTER Group, owned 70% by AEROSPATIALE France and 30% by Daimler Aerospace (DASA) of Germany. The military version of the BO 105 include the antitank version with weapon-carrying outriggers and the scout version which has a mast-mounted sight above the main rotor. Missions include: direct air support, antitank, reconnaissance, search and rescue, and transport. In addition to reconnaissance, observation and surveillance missions, this helicopter is particularly suitable for carrying task forces and casualties, thanks to its unpartitioned cabin/cargo area. The helicopter is powered by two Allison 250-C 20B turbine engines and can easily be reconfigured for different armed duties, and particularly to support the following specific weapon systems: anti-tank missiles, rocket launchers, pod-mounted gun, gun turret, side-firing machine gun.
