Beginning in 2021, Zipline will begin making on-demand deliveries for Walmart for “select health and wellness products with the potential to expand to general merchandise,” Tom Ward, senior vice president of customer product at Walmart, said in a blog post.Zipline, which operates the world’s largest drone delivery network, is best known for delivering critical medical supplies — particularly blood — in hard-to-reach areas of Rwanda, the landlocked African country characterized by hilly and mountainous terrain.

The on-demand drone delivery trials with Zipline will take place near Walmart’s home in Northwest Arkansas.

According to Ward, “Zipline will operate from a Walmart store and can service a 50-mile radius, which is about the size of the state of Connecticut.”

The system will facilitate rapid delivery times of under an hour, Ward wrote, and helps curb carbon emissions.

“The operation will likely begin early next year, and, if successful, we’ll look to expand,” the executive added.

Ward added that Zipline had delivered more 200,000 medical products across thousands of medical facilities in multiple countries.

“This uniquely positions them for national-scale operations across the United States,” Ward added.
