The Britten-Norman Defender is a multi-role utility transport aircraft, manufactured by Britten-Norman of the United Kingdom. It is the military version of the Britten-Norman Islander, developed for roles such as utility transport, casualty evacuation, counter-insurgency and light attack, forward air control, patrol and reconnaissance.
First flown in May 1970, the Defender was based on the civilian Islander, and has a larger airframe with four underwing hardpoints for pylons to attach 2,500 pounds (1,100 kg) of fuel tanks, bombs, missiles, 7.62-mm (0.3-inch) machine-gun pods, rocket pods, flares, sensors and other stores.
The BN-2B (piston version) and BN-2T (turbine version) are used in military, coastguard, and police operations in several countries.
The BN-2T-4S Defender 4000 is an enhanced version of the BN-2T Defender intended for the aerial surveillance role. Compared to earlier Defenders, it has a stretched fuselage, the enlarged wing from the Trislander, a new nose structure capable of accommodating a FLIR turret or radar, and an increased payload. The prototype Defender 4000 first flew in 1994.
In 1996, the Royal Cambodian Air Force deployed its three BN-2 Defenders in support of the dry season offensive against Khmer Rouge insurgents. The Defenders were armed with machine guns and rockets, and even dropped mortar rounds. One Defender was lost during the operation.
In 2003 the British Army bought four Defender 4000 aircraft, known in service as the Defender AL1, fitted with under-wing defensive aids dispensers and an electro-optical turret under the nose. Since then, one other has been converted to Defender AL2 specification and three more Defender AL2s and one Defender T3 trainer have been ordered.
