Aircraft facilities: Aircraft fuel stowage was 303 000 l. There was 1 crane for handling seaplanes.

Project history: Unique American purpose-built small seaplane tenders. Intended for seaplane maintenance on distant Pacific islands and atolls with a harbour shallow depth that has predetermined occurrence in the design assignment of strong draught limitations. As in a wartime it was supposed to attract these ships as escorts of large tenders, the project provided fitting of anti-submarine armament and sonar.

Small seaplane tenders could provide basing of one seaplanes squadron. Designed armament was limited by two DP 127/38mm guns and 4 12.7mm MGs, but in 1942, when the first ships of this class were already commissioned, the new structure of armament has been approved: 4x1 127/38mm, 8x1 20mm MGs and 2 DCTs. Really ships were commissioned having from one to four 127mm guns and 6-8 20mm MGs.

In total 39 ships of this type have been ordered, the order for six of them later had canceled, four were completed as PT depot ships (AGP6-9).
