The BO 105 P-1A1 is the predecessor of the Eurocopter EC-665 TIGER.
The BO 105 C was developed in 1972 and the German Ministry of Defence selected this model for its light observation helicopter program, purchasing 100 helicopters in 1977. A specialist anti-tank version armed with Euromissile HOTmissiles and designated as the BO 105 PAH-1 was procured by the German Army around the same time, with a total of 212 eventually being delivered.
Military operators would commonly operate the type at a very low altitude to minimise visibility to enemies, the BO 105 being well matched to such operations as the helicopter’s flight qualities effectively removed or greatly minimised several of the hazards such a flight profile could pose to pilots. When outfitted with optional auxiliary fuel tanks, a basic model BO 105 would have a flight endurance of roughly five hours under load.e German Army around the same time, with a total of 212 eventually being delivered.
