————————

On 15 November 1972, Bagley entered the Long Beach Naval Shipyard and began an extended post-shakedown availability during which her main propulsion plant was converted to use Navy distillate fuel.  I joined the Bagley on 23 Jan 73, in Long Beach CA. The Bagley completed repairs and modifications on 4 May 1973 and returned to San Diego that same day. She began training operations along the California coast three days later and continued those evolutions through most of the summer. She stood out of San Diego on 11 September and headed for the western Pacific.  She conducted training operations in the Hawaitan Islands between 17 and 26 September and then resumed her westward voyage.  She arrived in Yokosuka, Japan, on 5 October.  A week later, the escort ship shaped a course for the Philippines.  Bagley arrived in Subic Bay on the 17th for two days of upkeep and liberty.  On the October 19, 1973, she weighed anchor and headed for a patrol station in the Gulf of Tonkin.

Ten days later, she received orders to accompany Hancock  (CVA-l9) to the Indian Ocean.  That contingency force went to the western portion of the Indian Ocean in response to hostilities that had broken out between Israel and her neighbors, Egypt and Syria.  Bagley spent the next seven weeks on patrol in the Indian Ocean as an indication of American resolve to end the fighting in the Middle East and as a deterrent to keep Soviet forces from intervening in the conflict.  [Not mentioned, but we entered the Red Sea and from November 29 until Dec 04 we were docked in the port of Massawa, Ethiopia (now Eritrea).]

On 17 December 1973, Bagley reentered Subic Bay for an extended leave and upkeep period.  For the remainder of the deployment, the warship participated in the usual 7th Fleet exercises punctuated by port visits to Hong Kong; Keelung, Taiwan; Buckner Bay, Okinawa; Pusan, Korea; and Yokosuka, Japan. On 20 February 1974, she departed the latter port and began the voyage home.  The warship stopped at Midway Island and Pearl Harbor before arriving in San Diego on 8 March.  On 16 August 1974, I shipped out and  headed for Keflvik Naval Air Station, Iceland.
