IAI Heron

[galleryview id=84]

Introduction
The IAI Heron (Machatz-1) is a medium-altitude long-endurance unmanned aerial vehicle (UAV) developed by the Malat (UAV) division of Israel Aerospace Industries. It is capable of Medium Altitude Long Endurance (MALE) operations of up to 52 hours’ duration at up to 35,000 feet. It has demonstrated 52 hours of continuous flight, but the effective operational maximal flight duration is less, due to payload and flight profile. There is a new version, Heron TP, also known as IAI Eitan.

On 11 September 2005, it was announced that the Israel Defense Forces purchased US$50 million worth of Heron systems.

Design and Development
Heron navigates using an internal GPS receiver, and either a pre-programmed flight profile (in which case the system is fully autonomous from takeoff to landing), manual override from a ground control station, or a combination of both. It can autonomously return to base and land in case of lost communication with the ground station. The system has fully automatic launch and recovery (ALR) and all-weather capabilities.

Heron can carry an array of sensors, including infra-red and visible-light surveillance, intelligence systems (COMINT and ELINT) and various radar systems, totaling up to 250 kg (550 lb). Heron is also capable of target acquisition and artillery adjustment.

The payload sensors communicate with the ground control station in real-time, using either direct line of sight data link, or via an airborne/satellite relay. Like the navigation system, the payload can also be used in either a fully pre-programmed autonomous mode, or manual real-time remote operation, or a combination of both.

Operational History
The Heron saw significant use during Operation Cast Lead in Gaza of 2008–2009. During the deployment, each brigade combat team was assigned a UAV squadron for close support. This was the first Israeli operation in which UAVs, helicopters, and fighter jets were allocated to ground forces directly without IAF central command authorizing sorties. Air-support controller teams operated alongside brigade commanders at the front emphasizing the brigade commander’s utilization of direct air assets. A high degree of situational awareness was achieved by maintaining at least a dozen UAVs in flight over Gaza at all times. Aerial surveillance was provided by Heron and Hermes 450 UAVs and Apache attack helicopters. Along with coordination between the Air Force and ground troops, Israel ground forces were able to utilize cooperation with the Israel Security Agency by having operatives attached to the forward units. This inter-service coordination allowed for a higher level of tactical awareness and the ability to strike time-critical targets.

Other countries operating the Heron include Singapore, India and Turkey. France operates a derivative of Heron named Eagle or Harfang. In 2008, Canada announced a plan to lease a Heron for use in Afghanistan, starting in 2009. As of mid-2009, Australia is leasing two Herons as part of a multi-million dollar lease to operate the vehicles in Afghanistan.

Heron variants
Turkey operates a special modified version of the Heron, which utilizes Turkish designed and manufactured electro-optical sub-systems. For example, the Turkish Herons use the ASELFLIR-300T airborne thermal Imaging and targeting system designed and manufactured by ASELSAN of Turkey. The Turkish Herons have also stronger engines in order to compensate for the added payload created by the new ASELFLIR-300T. This is the same FLIR system what will be used by the TAI/AgustaWestland T-129 attack helicopter and the TAI Anka MALE UAV. IAI staff maintain that the Turkish Heron’s “with its enhanced performance, is better than all existing Heron UAVs operating worldwide”. Turkish Aerospace Industries (TUSAŞ) provide maintenance and overhaul services for the Turkish Herons.
France operates its own special version of the Heron, called Harfang.
