The early days of drone warfare

 

CDR Salamander noted yesterday that the Iranian Shahed-136 drone was based, at least in part, on a joint US-West German development from the 1980's.  He quotes Wikipedia's description.

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. 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.

There's more at the link.

That's true, of course, but there was an additional drone being developed at the same time that was also sold to Israel.  It was a South African project known as the Kentron ARD-10 Lark.  The following image and report date from the early 1990's.

At the time, South Africa was becoming increasingly sophisticated in its use of the relatively primitive unmanned aerial vehicles of the time.  I had some peripheral involvement in the electronics being developed for them.  An account of the period includes the following:

Various use must have been made during the following years after 1983, however the next open mention was during the 1987-88 raids into Angola (Operations Modular/Hooper/Packer) in which extensive use was made of UAV's for surveillance, reconnaissance, artillery spotting and more interestingly to lure Soviet SAM batteries out of hiding so that our long range G-5/6 guns could hit them. Two Kentron Seeker systems were lost to the last mentioned tactic, although it was apparently more than worth it - many expensive SAM-8/9/13 were fired attempting to shoot the Seeker's down, in doing so not only did they waste valuable ammunition - but also revealed their positions and many of their Soviet SAM sites were then promptly destroyed by G-5/6 artillery fire (apparently one Seeker survived between 16-17 SAM-8 missiles being fired at it before it was finally shot down).

The latter engagements were during 1987/88.  As a direct result of those engagements, the ARD-10 was developed as a more advanced surveillance and reconnaissance platform, with particular emphasis on forcing enemy radars and air defense ordnance to reveal their position.  However, during the same period South Africa embarked on the process that was to lead to democratic elections in 1994, and the ARD-10 was one of many military projects (including the Carver strike fighter) that were canceled due to the peace conference and the end of the Border War.  Its design was sold to Israel for a relative pittance, probably at about the same time that the US-West German project found the same destination.  There seems little doubt that both of those designs were used as input to Israel's Harpy drone, shown below.

It achieved wide international sales and was prominent in a number of smaller wars.  It was later developed into the much more sophisticated Harop drone, shown below, which in modern versions is pretty much state-of-the-art in its field.  It became prominent due to its success in the Second Nagorno-Karabakh War in 2020. 

Information available about the Kentron ARD-10, Dornier DAR, and Israeli Harpy drones was undoubtedly studied in Iran, and that country's subsequent Shahed 136 bears an unmistakeable resemblance to them all.  All of those aircraft are relatively backward and primitive compared to modern designs;  but then, for a simple strike drone that can be bought cheaply in large numbers and launched in "swarms" to overwhelm enemy defenses, one doesn't need great sophistication.

Russia manufactures the Shahed 136 under license as the Geran-2, and has apparently developed a jet-propelled version of the drone that flies much faster and higher.  This will be harder to intercept, and if its cost can be kept low enough to afford mass production, may make air defense's job much more difficult.  As long as the cost to intercept the drone can be kept higher than the cost to build and operate the drone, the attacker will have an economic advantage.  We'll have to see whether that remains the case as drone technology advances.  If "stealthy" attack drones can be made cheaply enough (something I'm sure many nations are working on), they may pose a grave threat to almost all air defense systems.
