Lee Joseph "Bru" Archambault (born August 25, 1960) is an American test pilot and former NASA astronaut.

Archambault left NASA in 2013 after a 15-year career with the agency in order to become a test pilot for Sierra Nevada Corporation on their Dream Chaser orbital spaceplane project.

He then reported to Cannon Air Force Base, New Mexico, where he served as a combat ready F-111D pilot in the 27th Tactical Fighter Wing until April 1990.

From November 1990 to April 1991, he deployed to Saudi Arabia in support of Operation Desert Shield/Desert Storm and flew twenty-two combat missions in the F-117A during the Gulf War.

The mission delivered the S3/S4 truss segment to the International Space Station and swapped a long duration crew member.

The mission delivered the final set of solar arrays to the space station, as well as long duration crew member Koichi Wakata.

Like the Space Shuttle, which Archambault has previously flown, Dream Chaser is designed to launch vertically and land horizontally on a runway.
