Israel Aerospace Industries (IAI) is currently advancing its largest unmanned aerial vehicle (UAV), the Heron TP, also known within the Israeli Air Force (IAF) as the Eitan.
Already a massive platform, this drone is set to grow even larger, solidifying its place in aviation history with a current wingspan of 26 meters, an impressive width equivalent to a Boeing 737 passenger airliner.
The main purpose of the Heron TP is to conduct long-range Intelligence, Surveillance, Target Acquisition, and Reconnaissance (ISTAR) missions, alongside high-altitude maritime patrol and long-range precision strikes.
It operates under the IAF’s 210 “White Eagle” Squadron.
What differentiates this platform from standard tactical drones is its Medium-Altitude Long-Endurance (MALE) class capability, which allows it to fly at a ceiling of 45,000 feet, far above commercial traffic.
It boasts a maximum takeoff weight of 4,650 kilograms and can carry a massive, diverse payload of 2,700 kilograms, powered by a 1,200-horsepower Pratt & Whitney Canada PT6A turboprop engine.
First flown in 2006, the Heron TP remains heavily in use two decades after its initial creation because of its open architecture design.
This layout allows engineers to easily integrate modern technologies like satellite communication (SATCOM) links, advanced electronic intelligence (ELINT) suites, and artificial intelligence for sensor fusion.
It can remain airborne for over 30 hours—with some missions tracking beyond 36 hours—giving it a striking operational range of over 7,000 kilometers.
Financially, a single Heron TP unit is estimated to cost between $35 million and $45 million.
However, system packages vary wildly; for instance, Germany approved a prominent procurement package for five modified systems valued at 580 million euros, while a later deal for three additional units and five years of operational support was valued near 930 million euros.
While exact production numbers remain classified by IAI and the Israeli Ministry of Defense, dozens have been manufactured to support domestic defense alongside international clients, including the air forces of Germany, India, and Greece.
