    Support Ship Cimarron class

    The Cimarron class of fleet oilers (AO) was introduced in the early 1980s but their design proved to be too small to satisfy the Navy needs so the ships were cut into two sections and a third about 35.7 m long was added in order to increase the fuel load. Further ten planned ships were cancelled and the more capable Henry J. Kaiser class was build instead
