His commands at sea included Attack Squadron Twenty-Seven (VA-27), the combat stores ship USS San Jose, the aircraft carrier USS Coral Sea, Carrier Group 4, the United States Second Fleet, and NATO's Striking Fleet Atlantic.

After his military career, Johnson served for a decade as the President and Chief Executive Officer of the Navy-Marine Corps Relief Society.

Founded in 1904, the non-profit provides financial, educational, and other assistance to active-duty and retired sailors, Marines, and their eligible family members.

During his tenure, the Society disbursed more than $670 million in interest-free loans, grants, and tuition assistance for naval service families.
