The original piston-engine Defender has seen service since the 1970s in Central Africa. In the 1980s and 90s a turbine version was introduced, which has seen service with, amongst many others, customers such as the UK Ministry of Defence and the Royal Oman Police.
The latest version of the Defender comes from a similar pedigree, with its short field landing capability, durability, low purchase and operating costs and low maintenance. However, it also incorporates numerous improvements such as the extended cabin, enhanced range and endurance, increased payload, electronic flight instruments and the scope to
integrate a wide range of specialist mission equipment.
GETTING THE JOB DONE
The Defender's transit speed is 160 knots, but it also has exceptional low-speed handling and manoeuvring capabilities at around 70-90 knots allowing for continuous tight turns during low level observation, inspection and photography. At this low speed it has an endurance of around 8 hours assisted by an extended fuselage and larger wings which has been developed for improved fuel capacity. Fitted with durable and fuel efficient Rolls Royce Allison engines, 250-B17F flat-rated at 400hp with 200amp generators, the Defender has a proven track record as the world's most versatile, reliable and economic task-oriented aircraft.
“The Defender. The ultimate solution in combining cost
effectiveness and performance with rugged durability.”

Defender pedigree includes: BN2 Piston Defender, BN2T Turbine Defender, BN2T-4R Defender and the latest BN2T-4S Defender.
Defenders have served with distinction in armed forces and military fleets across the world, including the UK Army Corps. It is an invaluable tool in training military personnel – ten parachutists and a jump master can easily be accommodated, and a sliding door fitted. The Defender can act as a targeting system for long range weapons and land
based vehicles. For speed of reaction, flexibility, command control and communications, the Defender
is particularly efficient at maximising surveillance co-ordination when other resources are limited.
“The Defender has a proven track record, not only in
solving transportation problems simply and economically
but in providing reliable support for other military vehicles.”

TYPICAL MISSION ENDURANCE PROFILES
The Defender’s proven track record in operations related to Coast Guard, Exclusive Economic Zones and Maritime Patrol is unmatched by other aircraft in its class. Long range endurance, aided by the aircraft’s refined and enhanced fuel storage options, gives maximum surveillance/protection control with competitively low running and
maintenance costs. A variety of long range radar and search equipment can be fitted, putting the Defender a long way in front of its competition.

Exceptional mission coverage
Extended range fuel options allow for both littoral and deep water surveillance capabilities, operating autonomously or in conjunction with surface vessels. In one mission the Defender could potentially cover a sea area of approximately 500,000 square km.
The Defender is operated on special missions worldwide, ranging from geological surveys and aerial mapping to environmental monitoring, pest control, and air ambulance operations. Its low loiter speed, long endurance and extremely economical performance make it the ideal solution for a variety of agencies and initiatives.
An excellent short field landing capability and extended mission range make the Defender ideal for operations in even the most inhospitable areas.
