During his work with this group, took assignments of one or more years with naval commands in which he served on the staff of commanding officers, acting as a scientific analyst to them. Back in Washington, his study of US Navy Operations in the Korean War developed a set of planning factors applied to the development of the A-6 attack plane. Became one of the founding members of the Operations Research Society of America (ORSA) and completed a master's degree in mathematics at MIT.
Served on the staffs of the Commanders of Atlantic, Mediterranean, and Pacific fleets. While assigned operated with the fleet aboard aircraft carriers and cruisers at sea during all operations of the fleet. He was aboard the USS Ticonderoga on the staff of the carrier force commander during the first actions in the Tonkin Gulf that led to wider involvement of the US Navy against North Vietnam. Co-authored a handbook of guidance on weapons for use by the fleet in operations.

Also served as Executive Secretary on two panels of the Defense Science Board which developed and published Lessons Learned on Test and Evaluation of Military Systems.
Rejoining the Navy analysis group now known as the Center for Naval Analyses, he developed a study team concentrating on operational logistics for the forces afloat. He described all these experiences with Naval forces afloat and ashore in a book published in 1992, Fields of Operations Research.
Retiring in 1992, he served for one year representing the Operations Research Society of America (now known as INFORMS, the Institute for Operations Research and Management Science) to the American Association of Engineering Societies Committee on Pensions.
