CH-47D Chinook

The US Army CH-47D is a twin-engine, tandem rotor helicopter with the role of troop and cargo transport. The lack of a tail rotor allows for a longer than normal cabin, increasing the helicopter's cargo capacity.

The first Chinook, the CH-47A, was developed for use in Vietnam in 1962and gone through a series of improvements up to the current model, the CH-47D.

The CH-47D can accommodate up to 44 troops and carry up to 26,000lbs of stores slung from 3 cargo hooks fixed to the helicopter's belly.

With its size, power and range, the Chinook is often the only US helicopter capable of performing certain missions, be it delivering supplies across the deserts of Iraq or the mountains of Afghanistan.

When configured for so-called, 'Fat Cow' operations, the CH-47D can be fitted with a series of internal fuel bladders, known as Extended Range Fuel System [ERFS] and perform a refueling role at Forward Arming And Refueling Points (FAARPs).

Whilst not used gunships, the CH-47D is routinely armed with 3 machine guns, either M60D or M240D 7.62mm belt-fed guns, attached to pintle-mounts in the forward cabin windows and rear ramp.
