Retired Navy Capt. John Kenneth Batchellor, 74, a retired Navy engineer who lived in McLean after retiring from active duty in 1968, died Wednesday in a hospital in Pinehurst, N.C., after a heart attack. He was on vacation.

Capt. Batchellor was a native of Orleans County, N.Y., and was a 1929 graduate of the Rensselaer Polytechnic Institute in Troy, N.Y. He later earned a master's degree in civil engineering.

He received his Navy commission in 1936, and during a career spanning more than 30 years served at posts in Guam, Japan, and the Panama Canal Zone, as well as the continental United States.

From 1939 to 1941, he was public works officer at the Naval Air Station in Pensacola, Fla. He then spent two years in Charleston, S.C., where he helped direct construction at the Naval base and at a Navy hospital.

During the remainder of the war he trained naval engineers that were to go overseas with construction battalions (Seabees), was a plans and logistics officer with the Bureau of Yards and Docks in Washington, and was a liaison officer between the bureau and the office of the Chief of Naval Operations.

After the war, he was assigned to engineering projects in Guam and Okinawa, served in the Office of Naval Research and Office of the Joint Chiefs of Staff. He also helped direct engineering projects for NASA in the 1960s. His last post was as public works officer for the Washington Naval District before retiring in 1968.

In October 1968, Capt. Batchellor joined the engineering and consulting firm of Buchard-Horn, and opened their Washington office. Buchart-Horn was involved in Metro construction. Capt. Batchellor retired a second time in 1977.

He was a member of the American Society of Military Engineers, the National Society of Professional Engineers. His hobbies included golf.

Survivors include his wife, the former Mary Ezella Thomas of McLean; two sons, J. Kenneth Jr. of Fairfax, and Duncan Paul Batchellor of New York City; two daughters, Anne Browne of Reston, and Navy Lt. Cmdr. Mary Pamela Batchellor of Monterey, Calif. and four grandchildren.

The family suggests that expressions of sympathy be in the form of contributions to the Seabee Memorial Scholarship Association or the Heart Fund of the American Heart Association.
