Leverett A. Meadows, 73, an official of the Bureau of Ships in the Navy Department who retired in 1973 after 40 years of service, died Friday at Suburban Hospital in Bethesda. He had pneumonia and leukemia.

Mr. Meadows was born in Wuchow, China, the son of Baptist American medical missionaries there. He grew up in the southern United States and graduated from Baylor University with a bachelor's degree in physics. He moved to Washington about 1932 and begin his career with the Navy Department the following year.

He took graduate course at George Washington University and attended the Capital Radio Engineering Institute, becoming an electronics engineer. At the time of his retirement, he was head of electronics configuration management and publications for the Bureau of Ships.

For several years during his career, Mr. Meadows represented the Defense Department on a committee to standardize electronics and electrical symbols. He was made a fellow and senior life member of the Institute of Electrical and Electronics Engineers.

Mr. Meadows, who lived in Kensington, was a past president of the Washington Society of Engineers and of the Naval Society of Engineers and Scientists. He was a Registered Professional Engineer in the District of Columbia and had several other professional affiliations. He also was a member of the American Association of Retired Persons and the First Baptist Church of Washington.

Survivors include his wife, the former Alba Geraci, to whom he was married for 46 years, of Kensington; two daughters, Constance Carol Meadows of Brussels, Belgium, and Margaret Fischer of Columbus, Ohio; one sister, Dorcas Claunch of Commerce, Tex., and two grandsons.

The family suggests that expressions of sympathy be in the form of contributions to the American Cancer Society, or to the First Baptist Church of Washington Building Fund.
