Roan (DD-853) from February 1947 to July 1948, and the USS Deming (PCS-1392) from July 1948 to June 1949.

There he tutored U.S. Marine Corps aviator John Glenn in math and physics. He was a test pilot until January 1957.  In 1959, the U.S. Navy sent Stockdale to Stanford University where he received a Master of Arts degree in international relations and comparative Marxist thought in 1962.
