Phoenix breakwatersとは 意味・読み方・使い方

The Phoenix breakwaters were a set of reinforced concrete caissons built as part of the artificial Mulberry harbours that were assembled as part of the follow-up to the Normandy landings during World War II. They were constructed by civil engineering contractors around the coast of Britain. They were collected and sunk at Dungeness and Selsey, and then towed across the English Channel to form the Mulberry harbour breakwaters replacing the initial 'Gooseberry' block ships. Further caisson were added in the autumn of 1944 to re-enforce the existing structure to cope with the harbour continuing in use longer than planned.
