Development
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.
Defender 4000
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.[1] The prototype Defender 4000 first flew in 1994.[2]
Operational history
The Mauritnian Air Force employed six BN-2A-21 Defenders in the Western Sahara War against POLISARIO forces in 1976, losing two of them in action.[3]
The FBI deployed one Defender for electronic aerial surveillance on the Branch Davidians' compound during the siege of Waco in 1993.[4]
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.[5]
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.[6] Since then, one other has been converted to Defender AL2 specification and three more Defender AL2s and one Defender T3 trainer have been ordered. They have been employed in the command and communication role with limited use in transporting personnel.
The Irish Air Corps bought one Defender 4000 in 1997. It is operated by the Garda Air Support Unit.
In 2014 the Philippine Navy sent one of its Defenders to assist a multinational search and rescue party led by the government of Malaysia in search of the missing Malaysia Airlines Flight 370.[7]
