Project history

These ships were intended as successors to the Landing Ship Dock with much increased troop (930, 840 in flagships) and cargo (about 2500t) capacity and a smaller well deck (51.2x15.2m), accommodating one LCU and three LCM-6 or four LCM-8 or twenty LVT; in addition there was a large crane at the after end of the superstructure which can launch craft carried on the flight deck, typically two LCM-6 or four LCPL. Ships after the Austin (LPD 4) have a hangar 17.7-19.5m in length and 5.6-7.3m in width, extensible to about 24.5m. The deck has two helicopter spots, but ships have deployed with up to six CH-46 embarked.

Austins were somewhat enlarged than Raleigh. The LPD Coronado served as Middle East Flagship (AGF11 vice LPD11).

LPD7-13 were fitted as amphibious squadron flagships and had an extra bridge level. A proposed LPD16, to have been built under the FY66 programme, was deferred in favour of the LHA programme then cancelled in 1969. The other LPDs were built under the FY59 (prototype), FY60 (1), FY61 (1), FY62 (3), FY63 (4), FY64 (3) and FY65 (2) programmes.

Ponce in 2012 was reclassified as Interim Afloat Forward Stating Base AFSB(I). Her role became support of mine countermeasures, coastal patrol, small boat and RIB operations in the Persian Gulf area.

All ships of class later can carry 1 LCAC.
