What early landing-ship docks would change in 1939

How would four Ashland-class landing ships have helped the Royal Navy by 1939?

They would have been useful command and amphibious assets for Norway, raids such as Claymore, the Mediterranean, and the Indian Ocean.

Four Ashland-class landing-ship docks would give Britain purpose-built command and amphibious assets at the outbreak of war. Norway offers the clearest early use, where well-deck ships could support operations that otherwise relied on improvised transport. Operation Claymore and similar raids would gain a dedicated platform for landing craft and command arrangements. Comparable work would also be available in the Mediterranean and Indian Ocean.
