Zipline International Inc. is an American company that designs, manufactures, and operates delivery drones, with distribution centers in the United States, Rwanda, Ghana, Japan, Nigeria, Côte d'Ivoire, and Kenya. As of January 2026, Zipline's drones have completed more than two million commercial deliveries and flown over 120 million miles. Zipline has two different drone platforms, P1 is used for deliveries to rural areas and P2 in urban and suburban areas. All Zipline drones navigate and avoid obstacles autonomously using custom software the company developed, which run on Nvidia chips. The Zipline fleet is one of the world’s largest commercial deployments of autonomous robots.
History
Zipline originated from Romotive, a company founded in 2011 by Keller Rinaudo Cliffton that produced an iPhone-controlled robot. Romotive ceased operations in 2014, after which Rinaudo, Ryan Oksenhorn, William Hetzler, and Keenan Wyrobek began developing a fixed-wing drone platform intended for medical delivery. This effort became the basis for Zipline. The company began operations in Rwanda in October 2016 following a government agreement to deliver blood and medical supplies to rural clinics from a centralized distribution center. A second Rwandan center opened in 2018 as the scope of deliveries expanded to include routine vaccines and essential medicines. Zipline launched operations in Ghana on April 24, 2019 under a government contract that provided drone delivery services to public-sector health facilities. The program later expanded to multiple distribution centers serving additional regions. Beginning in 2020, the company participated in regulatory programs, including the FAA type-certification process for delivery drones in the United States. It also deployed temperature-controlled payload systems to support delivery of vaccines requiring cold-chain conditions, including during COVID-19 vaccination campaigns in parts of Africa. From 2022 onward, Zipline initiated operations outside Africa, including a partner-operated distribution center in Japan and limited pilot projects in the United States. It also introduced a new platform aimed at home deliveries in denser urban and suburban environments. By the mid-2020s, Zipline had become an example of a Silicon Valley startup whose most visible commercial activity occurred abroad rather than domestically, with most of its business based on government contracts for transporting medical supplies to remote or hard-to-reach areas in multiple African countries. In April 2024, Zipline completed its millionth commercial delivery, having flown more than 70 million autonomous commercial miles. In January 2026, Zipline completed its two millionth commercial delivery, with over 120 million autonomous miles flown.
Platform 1
The Platform 1 model is a "forward flight lift only" fixed-wing drone weighing 44 pounds (20 kg) and can carry up to 4 pounds (1.8 kg) of cargo. While they can fly 300 km (190 mi) on a charge, they limit themselves to destinations within 80 km (50 mi). The drones have a quickly-replaceable battery that allows rapid turnaround between flights. It has an inner carbon-fiber frame and an outer polystyrene shell. The wingspan is 11 feet (3.4 m). The drones have two propellers for redundancy and can fly safely on a single propeller or motor. A parachute that will bring the drone to the ground can be deployed if a larger set of faults occur. If the drone crashes, the outer components are frangible, breaking to release energy and impact the ground with less force. Zipline's drones are capable of "level 4" autonomy: the ability to complete travel autonomously under normal environmental conditions without requiring pilot oversight.
Operation
Medical staff at remote hospitals and clinics place orders with Zipline, a fulfillment operator receives this order and prepares the medical products into a special delivery package with a parachute. A Zipline flight operator then packs the medical products into a drone and performs pre-flight checks. The drone is then launched with a supercapacitor-powered electric catapult launcher which accelerates it to 67 miles per hour (108 km/h) in 0.33 seconds. The drone cruises at 101 km/h (63 mph) at an altitude of 80–120 metres (260–390 ft) above ground level, while a remote pilot at each distribution center monitors all drones in flight. The drone descends to 20–35 metres (66–115 ft) before dropping the package under a paper "Drogue" parachute. A payload can land within a 5 m (16 ft) diameter landing zone. The drone then returns to the distribution center and lands by its tail hook catching an arresting gear, similar to airplanes landing on an aircraft carrier. A Zipline distribution center can deliver medical supplies reliably anywhere within 100 km (62 mi), even accounting for mountainous terrain and severe weather.
Platform 2
The Platform 2 VTOL drones, launched in April 2025, are suited for shorter range home deliveries. They take off and land vertically, are capable of fixed-wing flight at up to 110 kilometres per hour (70 mph), and hover at an altitude of 100 metres (330 ft) to slowly lower packages on a wire. Packages are lowered in a delivery "droid" that uses sensors and propellers to deliver the package within a 1 metre (3.3 ft) diameter. The drones can carry up to 8 pounds (3.6 kg) of cargo within a 10 mi (16 km) radius, are capable of a more precise delivery than its previous generation, and can recharge autonomously.
