IAI Searcher
Type
Long-endurance multirole UAV.
Development
Existence of Searcher (Hebrew name Meyromit) was announced in the third quarter of 1989, and it made its public debut at the Asian
Aerospace exhibition in early 1990. One prototype had been completed at that time; a second was completed shortly afterwards. First
production Searcher rolled out November 1991. Deliveries of Searcher I to the Israel Defence Force began in mid-1992.
Variants
Searcher I: Initial production model. Detailed description applies to this version.
Searcher II: Improved version; public debut at Singapore Air Show, February 1998. Full details not released, but main configuration
changes are extended-span wings with modest sweepback, and a 61.9 kW (83 hp) UEL AR 68-1000 rotary engine with a 1.40 m (4 ft 7.1
in) diameter three-blade propeller. Useful load (payload plus fuel) is increased from 165 kg (364 lb) to 210 kg (463 lb), ceiling to 6,100 m
(20,000 ft), maximum take-off weight to 476 kg (1,050 lb), maximum range to 92 n miles (170 km; 105 miles), and maximum endurance
to 14 hours. Can be configured for tactical surveillance or as a 119 n mile (220 km; 137 mile) range communications relay aircraft. Several
payloads can be carried simultaneously. Existing Searcher Is can be upgraded to Mk II standard.
Airframe
Shoulder-wing monoplane with pusher engine and twin-boom tail unit, built largely of composites. Generally similar to AAI/IAI Pioneer,
but larger, with redesigned tail unit and high-aspect ratio tapered wing with new aerofoil section and Fowler flaps, contributing to much
enhanced payload/endurance performance. Non-retractable tricycle landing gear.
Mission payloads
Normal payload of MOSP real-time TV/FLIR, Controp ESP-600 CCD camera and/or air data relay; 1.5 kW onboard electrical power
supply. Elta EL/M-2055 synthetic aperture radar, introduced in 2001, enhances night/all-weather capability.
Guidance and control
The Searcher air vehicle can be controlled from a variety of GCSs which command, control, track and communicate with it and/or its
payload. Autopilot has return-home mode if command uplink is lost. The IAI GCS-2003 is a major subsystem, centralising all comments
sent by system operators to the UAV and all reports received from the UAV (including relay and mission UAVs). Three system operators
man the GCS, using computer-driven panels and other units installed in the control station bays. The GCS is housed in a shelter accommodating four such bays and, optionally, a mission commander's desk. Searcher is compatible with other Malat ground stations,
avionics and datalinks.
Launch
Wheeled take-off, or by pneumatic catapult or JATO booster rocket.
Recovery
Wheeled landing to arrester hook and cable.
Operational status
In production and service.
Customers
Israel (first Searcher I deliveries mid-1992, but operated for IDF by manufacturer until at least 1997; equip No 200 Squadron); Searcher II
operational with IDF from May 1999.
Foreign customers are not disclosed by IAI but include India (Searcher II, 10 delivered from 2001), Singapore (Searcher II, 42 for No
128 Squadron), Sri Lanka, Taiwan and Thailand (Searcher II, one system). Sales reportedly exceed 100 air vehicles and 20 GCSs.
