Kinda like the Merlin and the P51
In 1964 Bell further developed the model 205 by introducing a twin engine design. Known as the model 208, this featured the 1,240hp Continental XT67-T-1 powerplant, which consisted of two T72-T-2 turboshafts (each of which could support the aircraft) coupled through a gear box to a single driveshaft. The increase in performance and safety was attractive, and in 1968 the Canadian armed forces ordered what would be the model 212. The prototype flew in April 1969, powered by the 1,290 PWC PT-6T-3 powerplant. Delivery of 50 aircraft to Canada began in 1971. Later models utilised the PT-6T-3B. The model 212 was also adopted by the US military as the UH-1N. Delivery to the USAF of what would be 70 airframes began in 1971, while the USN and USMC took 221 aircraft. The VH-1N VIP transport (2 new-built and 6 conversions) is a variant. The model 212 received civil certification on June 30,1971, a 14 passenger version having been developed in parallel to the UH-1N. The large capacity and twin engine safety has made it popular with many operators in the medium lift, oil rig support and other roles. Augusta in Italy have license built the civil model AB212, as well as developing the maritime AB212ASW model. The model 412 is a development of the model 212, primarily distinguished by a four bladed rotor. Having first flown in August 1979 and been certified in February 1980, the first deliveries were made in January the following year. The aircraft is produced under license by Augusta as the AB412, and the Griffon military version. The type is also produced in Indonesia
