The Bo 105 is a light utility helicopter system recognized around the globe for its versatility, performance and safety record. The system has served (and continues to do so) in a military and civilian capacity in nations throughout the world, providing the ability to operate in many guises. The militarized version is capable of mounting the HOT and HOT-2 anti-tank missile system, making for one lethal and adept package.

The Bo 105 flew in prototype form in 1967, achieving full operational status by 1970. The cabin allows for a crew of two, plus three passengers and two medical litters in the medevac role. A series of two Allison-brand engines have powered most of the series, driving a four-blade main rotor system along with a two blade tail rotor. Visibility out of the cockpit is very good and several variants lengthen the cabin size, offering up more windows for improved visibility and additional storage/passenger seating space.

The German Army was the principle operator of the BO 105 series, taking on several hundreds into inventory. Anti-tank variants are fitted to fire up to six Euromissile brand HOT anti-tank missiles with later variants upgrading to the HOT 2 system with three missile launching tubes per side. The Swedish BO 105 CBS variant was similarly armed with the ESCO HeliTow anti-tank missile system. The Bo 105 was later replaced the in Eurocopter light helicopter line by the newer Eurocopter EC 145 system, with Bo 105 production ending as recently as 2001.
