Project history

This is an LHA derivative capable of handling the new air-cushion landing craft. Construction was originally planned for the FY87 programme, but it was moved up to FY84 to fill a perceived gap in Marine assault shipping. LHDs beyond the first five or six were intended to replace the lwo Jimas in the 1990s, so that by 1983 a total of about twelve was envisaged.

Unlike the original LHA, the LHD was conceived with a secondary sea-control role; they therefore incorporate maintenance facilities for at least twenty Harriers and for four to six ASW helicopters. The flight deck is so long that no ski-jump is required (were one provided, it would interfere with rolling helicopter take-offs). Quite aside from sea control, Marine Harriers might provide very useful support in an amphibious operation.

Differences from the LHA include use of an LSD/LPD-type lowering stern gate, vice the sectional, rising gate of LHA, provision for 3 LCAC in a single-bay, longer and narrower (98.1x15.2m) and 8.5m-high docking well, revised and strengthened aircraft elevators , internal stowage of a ship's boats, a bulbous forefoot to the bow, a squared-off flight deck forward, making entire deck capable of spotting 9 CH-53E helicopters at once, using HY100 steel for the flight deck, additional cargo elevators, new superstructure and better ballistic protection. They have 2127m² of vehicle parking space and 3087m³ of dry cargo space. Hospital facilities include 6 operating rooms, intensive care units and 47-bed ward expendable up to 578 beds.

Hangar bay area is 1923m², hangar is 6.4m-high and 25.9m-wide, it can accommodate 28 CH-46 equivalents. There are 2 34t capacity, 15.2x13.7m elevators, one at port side as on Tarawas and one at starboard side aft from the superstructure. 28 Harriers can be carried in absence of all helicopters. In a mine-countermeasures role ships carry 20 CH-46E, 6 MH-53E helicopters and 6 Mk 105 countermeasures sleds.
