Pakistan's aircraft has five on-board operator stations, versus three on modified EMB-145s and Sweden's two upgraded Saab 340s, a service ceiling of over 30,000ft (9,150m) and a mission endurance approaching 10h. The type also features enhanced engines, new generators, additional cooling for on-board mission equipment and a Saab HES-21 electronic warfare suite comprising laser, radar and missile approach warners and countermeasures dispensers.
The aircraft's fuselage has been strengthened to carry the Erieye radar, while its vertical tail has been extended to compensate for the payload, which provides 150e_SDgr coverage to each side of its conformal array. The Saab 2000's outer wing has also been strengthened to accommodate EW and signals intelligence sensors, and for the possible carriage of a towed radar decoy.
Saab says the use of new-generation radar transmit/receive modules with
60% higher output have increased the AEW range of the Erieye design, which can also now detect hovering helicopters and track small naval targets to a range of 350km (190nm).
The global fleet of Saab 2000s now totals 58 airframes. Around 20 of these are owned by the Swedish manufacturer's aircraft leasing unit, which says the type has a projected operating life of at least 75,000 flight hours. "We have sufficient aircraft for a lot of different customers," says Andersson, adding: "Given typical utilisation, they are due to operate for the next 35 to 40 years."
