Boeing finalized its acquisition of advanced technologies specialist Aurora Flight Sciences, broadening its reach into the realm of autonomy, unmanned and electric research, the companies announced today. Terms of the acquisition were not disclosed.

The sale was completed just a month after Boeing and Aurora announced they had reached an agreement for the acquisition. Aurora, which will be a subsidiary under Boeing’s Engineering, Test and Technology division, will operate as an independent unit under the name Aurora Flight Sciences, A Boeing Company. The Manassas, Virginia, firm will retain an independent operating model, but will be able to leverage Boeing resources to bring its emerging technologies to market.

In announcing the planned acquisition on October 5, Greg Hyslop, the chief technology officer and senior v-p of Boeing Engineering, Test and Technology, said the deal would bring “a new chapter for Boeing,” providing a range of expertise in the areas of robotic and unmanned technologies, electric systems and advanced aerostructures for programs such as the Bell 525 Relentless and Gulfstream G500, as well as a range of other technologies. Aurora projects have included the Alias robotic copilot, the e-VTOL under development in concert with Uber, the D8 "double bubble" commercial aircraft concept and the Centaur optionally piloted aircraft, among others.
