WASHINGTON — Boeing is selling off three subsidiaries to Archer Aviation in an all-stock deal and will become a “strategic partner” in the electric aircraft startup, the companies announced today.

Under agreements inked by the two firms, a joint press release says Boeing will transfer ownership of its drone subsidiary Insitu, air traffic management company SkyGrid and electric aircraft maker Wisk Aero, which was once a fierce rival of Archer. In exchange, Boeing will take a nearly 16.5 percent stake in Archer, according to the New York Times.

Brian Yutko, Boeing’s vice president for commercial airplanes product development, called the deal a “win-win” for both firms.

The deal “allows Wisk, SkyGrid and Insitu to accelerate capability development and time to market while ensuring Boeing capitalizes on its investments in these technologies over the past two decades through continued development in our core businesses,” Yutko said in the release.
