Retired Army Lt. Col. Robert W. Britt, 63, a combat veteran of two wars who was a civilian program analyst with the Navy Department, died of cancer Saturday at Malcolm Grow Medical Center at Andrews Air Force Base.

Col. Britt was a native of Freepor , Me., and received his Army commission in 1942. After earning his pilot's wings at Fort Sill, Okla., he served as an observation pilot in the Pacific Theater during World War II.

He flew artillery spotting planes for the Army in Korea during the conflict here. At the time he retired from active duty in 1952, he was serving with an Army aviation maintenance center in Germany.

His decorations included two Distinguished Service Crosses and 15 Air Medals.

For the past 15 years, Col. Britt had been a program analyst with the Navy's armament division in Washington. He was the recipient of the Navy's Superior Accomplishment Award earlier this year for his contributions to naval weapons systems programs.

He was a resident of Oxon Hill and was active in the Oxon Hill Manor Foundation, the Treasure Cove Citizens Organization, and the Potomac Enviromental Council. He also was a member of the Retired Officers Association.

Survivors include his wife of 20 years, the former Ingrid Ziegeler, and a daughter, Nicki U., both of Oxon Hill; three brothers, Harry A., of Barrington, R.I., Bernard M., of Cornish, Me., and Donald L., of Nantucket, Mass., and a sister Winona Dolloff of Fairbanks, Alaska.

The family suggests that expressions of sympathy be in the form of contributions to the American Cancer Society.
