History

The development of the Bo105 started in 1961 with the Bo103 which first flew in September 1961.

A larger version of the Bo103 was initially designated as Bo104, but this was soon followed by the Bo105.

The prototype of the Bo105 was equipped with two Allison T-63 turbine engines and a conventional rotor system. However, this helicopter experienced such resonance that it was destroyed.
The second prototype first flew in February 1967 and had a four-bladed rotor with solid fiberglass reinforced blades, which were later also applied to the production version.
The third prototype was equipped with two MAN turbine engines of 375 horsepower and first flew on December 20, 1967.

In mid-October 1970 received the Bo105 its type-certification of the German aviation authorities.
In April 1972 was also the FAA (Federal Aviation Administration) certification is obtained, so the type could also be exported to the USA.

The Bo105C was developed in 1972 and chosen by the German Ministry of Defence as a light observation helicopter. In 1977 100 examples were purchased while 112 examples of a special anti-tank version, designated as Bo105 PAH-1, equipped with Euro Missile HOT missiles, were purchased for the German army.

The Bo105CB with two powerful 250-C20B turbine engines Alison, was developed in 1976.
This type was extended by approximately 25 cm in response to American demand and released as Bo105CBS. [in the United States known as B0105 Twin jet]
A version of the Bo105CBS the B0-105LS, equipped with more powerful Allison 250-C28C had a higher take-off weight and appeared in 1984.

Production ended in 2001 after more than 1400 examples had been built.
