Avondale Shipyard
In February 1992 she departed Norfolk, Virginia and returned to Avondale Shipyard. Between February and December "Platte" was "jumboized", meaning that, after cutting the ship into two sections, a 35.7 m long section was added to increase the fuel load. The new "mid-body" section included an ammunition elevator, a second Fairbanks Morse emergency diesel generator, additional a/c capabilities as well as several cargo holds. She departed Avondale Shipyard December 1992 being the last of the five ships to undergo this process and completing it in 10 months.
