Retired Air Force Lt. Col. Anthony Alfred Gomes, 58, a specialist in nuclear and missiles systems, died of cancer Tuesday at Walter Reed Army Medical Center.

Col. Gomes became a civilian consultant to the Defense Intelligence Agency after his retirement in 1969, retiring for a second time in April of this year.

Born in Lisbon, Portugal, he came to this country as a child, grew up in Cambridge, Mass., and received a degree in mechanical engineering from Northeastern University in Boston in 1942.

Col. Gomes was commissioned in 1944 and served as an aircraft maintenance officer, flight engineer and intelligence officer.

He studied industrial administration at the Air Force Institute of Technology and was sent to Okinawa where he flew 24 combat missions as a flight engineer in Korea during the conflict there.

Col. Gomes later studied weapon systems management at the Martin Co. in Baltimore. After his retirement from active military duty he earned a master's degree in systems management from the University of California.

He was a project engineer associated with the Atlas. Thor and Titan missile development programs.

In 1963, Col. Gomes was assigned to the Atomic Energy Commission here. He managed its nuclear readiness-to-test program and provided technical liaison between the AEC and the Defense Department. Col. Gomes' decorations included the Legion of Merit, Soldier's Medal and Air Medal.

He is survived by his wife, Marion L., of the home in Falls Church; two daughters, Toni, of Arlington, and Diane Crist, of Florida, and a grandchild.
