While commercial package-delivery drones have been discussed in the U.S., the poor African nation of Rwanda plans to be first to actually launch such an automated network to carry blood and pharmaceuticals to remote locations.
HALF MOON BAY, Calif. — From a bluff overlooking the Pacific Ocean, a loud pop signals the catapult launch of a small, fixed-wing drone that is designed to carry medical supplies to remote locations almost 40 miles away.
The drones are the brainchild of a small group of engineers at a Silicon Valley startup called Zipline, which plans to begin operating a service with them for the government of Rwanda in July. The fleet of robot planes will initially cover more than half the tiny African nation, creating a highly automated network to shuttle blood and pharmaceuticals to remote locations in hours rather than weeks or months.
Rwanda, one of the world’s poorest nations, was ranked 170th by gross domestic product in 2014 by the International Monetary Fund. And so it is striking that the country will be the first, company executives said, to establish a commercial drone delivery network — putting it ahead of places like the United States, where there have been heavily ballyhooed futuristic drone delivery systems promising urban and suburban package delivery from tech giants such as Amazon and Google.
“The concept of drone ports is something that a very small decision-making unit in the country decided they were going to do,” said Michael Fairbanks, a member of Rwandan President Paul Kagame’s presidential advisory council. “It took a very short time. It’s something that America could learn from.”

That Rwanda is set to become the first country with a drone delivery network illustrates the often-uneven nature of the adoption of new technology. In the United States, drones have run into a wall of regulation and conflicting rules. But in Rwanda, the country’s master development plan has placed a priority on the use of the machines, first for medicine and then more broadly for economic development.
“Rwanda has a vision to become a technology hub for East Africa and ultimately the whole continent of Africa,” said William Hetzler, a founder of Zipline, which is based in the seaside town of Half Moon Bay, Calif. “Projects like ours fit very well with that strategy.”
The new drone system will initially be capable of making 50 to 150 daily deliveries of blood and emergency medicine to Rwanda’s 21 transfusing facilities, mostly in hospitals and clinics in the western half of the nation.
The drone system is based on a fleet of 15 small aircraft, each with twin electric motors, a 3.5-pound payload and an almost 8-foot wingspan. The system’s speed makes it possible to maintain a “cold chain” — essentially a temperature-controlled supply chain needed to provide blood and vaccines — which is often not practical to establish in developing countries.
The Zipline drones will use GPS receivers to navigate and communicate via the Rwandan cellular network. They will be able to fly in erratic weather conditions, enduring winds up to 30 mph.
When they reach the hospitals, they will not land but will drop small packages from very low altitudes. The supplies will fall to earth suspended by simple paper parachutes. The planes will then return to a home base, where they will be prepared for a new mission by swapping in a new battery and snapping in a new flight plan stored on a SIM card.
“This is the new face of the aerospace industry,” said Jay Gundlach, president of FlightHouse Engineering, an Oregon-based aviation consulting firm. “Established unmanned-aircraft companies should learn from Zipline’s agile and innovative culture.”
Like Zipline, others are attempting to solve the problem of the autonomous distribution of medical supplies. Many other systems being developed, however, are based on less-efficient multicopter or quadcopter designs that have shorter ranges and less ability to fly in all-weather situations.
In the United States, a firm named Flirtey has delivered medical supplies using multirotor helicopters as an experiment in Virginia. Another Silicon Valley startup, Matternet, is experimenting with the government of Malawi and with UNICEF to deliver infant HIV tests by quadcopter. Google X, the advanced research arm of Alphabet, is now developing a vertical-takeoff-and-landing system that will hover and deliver packages by the use of winches.
Zipline began in 2014, assembling an engineering team with aerospace-industry experience. It attracted talent from Space X, Aurora Flight Sciences, Boeing and Lockheed Martin, as well as Stanford and Google.
The startup has raised $18 million from investors including Sequoia Capital, GV (formerly Google Ventures), SV Angel, Stanford University and individuals including Jerry Yang, a founder of Yahoo, and Microsoft co-founder Paul Allen.
Hetzler said that by placing engineers who have consumer-electronics expertise in close collaboration with roboticists and aerospace engineers, it has been possible to rapidly build a highly automated system that can be operated by a staff of five to eight.
