Weighing over four tons,– also dubbed Heron 2 or “ ”, by its i Air Force ( ) designation – is designed to fly at high altitude on missions spanning over several days. was seeking a MALE capability for many years, in fact, the first application of an armed MALE was considered in the mid 1990s, as an alternative for the Arrow ballistic missile defense system, also developed by . , derived from the `heron TP platform, was developed under an Israel Ministry Of Defence (IMOD) program.
Apart from long range, long endurance Intelligence, Surveillance and Target Acquisition Reconnaissance (ISTAR) missions, Eitan is designed to execute a large variety of operational missions, including aerial refueling and strategic missile defense. Eitan made its maiden flight Friday, July 15, 2006 in Israel. The new MALE UAV will provide the Israel Air Force persistent, high altitude, long endurance ISR capability well beyond the reach of enemy air defenses, far beyond the Israeli borders. While the program is unveiled in June 2007, has already matured and, according to IAI, it is ready for serial production. Designed as a Multi-payload, Multi-mission platform to answer the requirements of the Israel Air Force, the HERON TP is powered by a single 1,200HP Pratt & Whitney Canada PT6A Turbo-Prop engine, powering a four blade propeller. The use of such powerful turbo-prop engine enables the aircraft to climb and operate at altitude above 40,000 ft avoiding any airspace conflict with commercial aircraft traffic. Using on board fuel and power resources, Heron TP is able to sustain continuous missions for over 36 hours with full mission payload. The aircraft is also equipped with deicing systems protecting the aircraft when flying through icing conditions.
