The United States Air Force's 10th Intelligence Squadron (10 IS) is an intelligence unit located at Langley AFB, Virginia. The squadron was first activated during World War II as the 678th Bombardment Squadron, a United States Army Air Forces combat organization. It was part of the first Boeing B-29 Superfortress group formed for the 58th Bombardment Wing, and served in the China Burma India Theater and Pacific Ocean Theater as part of Twentieth Air Force. The squadron's aircraft engaged in very heavy bombardment operations against Japan. The squadron received the Distinguished Unit Citation for its combat operations on three occasions. When the unit was returned to the United States in 1945 it was redesignated as the 10th Reconnaissance Squadron, but it was inactivated in March 1946.
