The '''Dornier Drohne Anti-Radar''' ('''DAR''') was an [[unmanned aerial vehicle]] developed by [[Dornier GmbH]] to detect and destroy enemy radar installations, especially those used for air defense, within a defined target area. The development project was terminated in 1994 and the system never entered service.
== Design and development == In the early 1980s, the [[United States]] and [[West Germany]] began developing an unmanned aerial vehicle (UAV) designed to detect and engage enemy radar systems. The aircraft was also intended to mimic larger aircraft, acting as a [[decoy]] to divert enemy fire from manned aircraft.<ref>Daimler-Benz Aerospace Aktiengesellschaft, Ausstellungstafel Drohne-Anti-Radar am Exponat in der WTS, Stand: November 2024</ref> On the German side, Dornier, and later its successor company [[DASA]], was working on the project for the [[German Air Force]]. During the project's development, a workable seeker head could not be developed, limiting its suitability for the intended anti-radar mission. This, along with the end of the [[Cold War]] and the collapse of the [[Soviet Union]], led to the project's eventual termination. Following the end of the project, details of the system's design were sold to Israel, which would develop its own [[IAI Harpy]].<ref name="DornierPost">{{cite journal |title=Drohne Anti-Radar |journal=Dornier Post, Zeitschrift für die Freunde des Hauses Dornier |issue=3/86 |pages=17–18 |language=de}}</ref><ref name="WTS_Exponat">{{cite sign |title=Exponatbeschreibung Drohne Anti-Radar, Inv.Nr. 27024 |publisher=[[Wehrtechnische Studiensammlung Koblenz]] |date=November 2024 |language=de}}</ref><ref name="SchweizerSoldat">{{cite journal |title=Drohne Anti-Radar |journal=Schweizer Soldat + MFD |volume=63 |issue=3 |year=1988 |page=38 |url=https://www.e-periodica.ch/digbib/view?pid=sol-001:1988:63::607 |access-date=2025-01-06 |language=de}}</ref>
The DAR is a [[delta wing]] aircraft constructed of [[composite material]]s. Two deployable rudders are integrated into each wing on either side of the fuselage; these are deployed before the final approach to the target. The fuel tanks are designed as slide-in units. The engine, with its attached generator, is mounted in the rear of the fuselage. It is started while still inside the launch tube. The two-bladed [[pusher propeller]] is connected to the engine via a coupling that engages the propeller to the engine only after the UAV has left the launch container. A [[booster rocket]] is located beneath the engine, providing the necessary thrust to accelerate the UAV from the launch container to the required flight speed. A [[fragmentation warhead]] was to be mounted in the fuselage directly behind the seeker head. For flight control, the computer receives data from a three-axis fiber optic [[gyroscope]] array, the air data sensors, the [[Navstar GPS]] receiver, and a [[magnetometer]]. The passive broadband seeker was intended to cover all potential radar systems in the target catalog. The required target parameters would be loaded before the drone's launch, and the seeker would scan the frequency bands during flight. Once a target was detected, the data acquired by the seeker would be used to guide the drone to the target.<ref name="Wehrtechnik">{{cite journal |title=Report |journal=Wehrtechnik: Zeitschrift für Wehrtechnik und Verteidigungswirtschaft |publisher=Verlag Wehr u.

The DAR system's ground components comprised a launch vehicle and a transport and reloading vehicle. These were 6x6 10-ton [[Iveco 260AH]] trucks with extended chassis. An initial plan to mount the system on the 6x4 10-ton [[MAN 260AH]] military truck, a standard vehicle of the [[German Armed Forces]], was abandoned after initial testing. The launch vehicle chassis housed the ground control station in a Cab II FmB with radio communication, a tipping mechanism for the launch container, a power supply system, and distribution boxes. Up to 18 DARs could be carried in this configuration. The transport and reloading vehicle was equipped with a loading crane.<ref name="Panzerbaer">{{cite web |title=Drohne, Anti-Radar (DAR) (Bw) |url=http://www.panzerbaer.de/ |website=Panzerbaer.de |access-date=2024-12-07 |language=de}}</ref>
