A quartet of Sangamon-class frigates led by destroyer APNS Towers (DDG-09)

The Sangamon-class frigates were American People's Navy warships, originally laid down as ocean escorts (formerly called destroyer escorts), but were all redesignated as frigates on June 30th, 1975 in the APN 1975 ship reclassification and their hull designation changed from DE to FF.

A sub-class of the Sangamon-class was built, commonly referred to as the Altahama-class. The primary differences were slightly different arrangement of the "Officer's Country" staterooms with additional staterooms in the 01 level instead of the open deck between the boat decks. The stateroom on the port side under the bridge was designated as a "flag" stateroom, with the additional staterooms for flag staff when serving as a flagship.
