Abe Karem - The Father of The Predator UAV

It was almost inevitable that Mr Karem would become an aerospace engineer. He built model aircraft at school, inspired by a teacher who had flown in a British Lancaster bomber during the second world war. Mr Karem went on to study aeronautics at Technion, Israel’s prestigious Institute of Technology, and then joined the Israeli Air Force. 

Within 13 years of graduating, Mr Karem had completed and deployed 16 projects, mostly conversions of jet fighters to add new weapons or capabilities. “In Israel at that time, we averaged six months from an idea to completion of flight testing,” he says. “Military programmes in the United States now typically take over 20 years to achieve first operation.” 

Mr Karem also built his first drone. During the Yom Kippur war of 1973, Israeli fighter-bombers attacking Egypt and Syria were being stopped by Russian-made air defences. Israel needed a fast decoy drone to activate the defensive radar systems, so they could then be hit using anti-radiation missiles. Mr Karem’s team designed, built and flew such a drone in just one month.

When Mr Karem arrived in America from Israel in 1977, the Pentagon had almost given up on robotic planes. At the time its most promising UAV, the Aquila, needed 30 people to launch it, flew for just minutes at a time and crashed on average every 20 flight hours. “It was insanity itself,” says Mr Karem. “It was obvious to me they were going to crash because they had 30 people doing something that could be done better by three.” 

Critically the drone, code-named Albatross, was developed by a handful of engineers, and operated by a team of just three. “Doing things with the absolute smallest team increases the chance that you’re not going to screw up,” says Mr Karem. “Nothing replaces highly talented people—white-hot passionate thinkers in love with doing challenging things.” 

After a flight test during which Albatross remained aloft for 56 hours, DARPA, the research arm of America’s armed forces, funded Mr Karem to scale it up into a more capable drone called Amber. It, in turn, evolved into the modern Predator.

Mr Karem founded a company, Leading Systems, in the garage of his Los Angeles home and began work on a drone that would ultimately transform the way America wages war. It was built in an intentionally low-tech manner, using plywood, home-made fibreglass and a two-stroke engine of the kind normally found in go-karts. “I wanted to prove that performance is largely a result of inspired design and highly optimised and integrated subsystems, not the application of the most advanced technology,” he says...full article
