Clayton M. Lewis, a sophomore at the U.S. Naval Academy in Annapolis, will face a court-martial on charges involving the theft of about $8,000 worth of goods from the midshipman's store, the academy announced yesterday.

Dennis Boxx, an academy spokesman, said the court-martial scheduled to begin today is only the second in 63 years at the Naval Academy.

Lewis, 20, from Roanoke Rapids, N.C., completed his freshman year last May. He is charged with larceny, conspiracy to commit larceny, receipt of stolen goods and unauthorized absence from the academy.

Boxx said the maximum penalty if Lewis were convicted of all charges would be confinement for 11 years and six months at hard labor, discharge from the Navy and forfeiture of all pay and allowances.

He said the missing items, including clothing, record albums and appliances, were taken between August 1984 and April 1985 from the store operated for midshipmen on academy grounds.

The most recent court-martial at the academy involved involuntary manslaughter charges against Michael R. Olmstead after an automobile accident on academy grounds in which another midshipman, Scott Thomas, was killed.

Olmstead, who argued that he was not driving the car, was convicted and sentenced to dismissal from the academy after a month-long court-martial in 1981. The sentence was suspended, and he was allowed to graduate after completing a four-month probationary period.

Olmstead's court-martial was the first since 1922, when a midshipman was found guilty in a hazing case, Boxx said.
