Clarification

A Sept. 28 article initially cited a Pentagon industrial-base report's incorrect statement that Raytheon "acquired Swift's UAS business via Northrop Grumman." In fact, Northrop Grumman acquired Swift's small unmanned aircraft product line and licensed Swift's Killer Bee drone to Raytheon, while separately leveraging the technology to develop Northrop-made Bat drones. The article has been updated online.
