 Work on the islands stopped in 1941 due to budgetary and resource shortages associated with the advent of World War II.In August 1947, construction of an airport on Kingman Island was again proposed, but the NCPPC disapproved the proposal in December.The project was proposed again in August 1948, because dredged material was still being placed on Kingman Island to build it up and large portions of the island remained undeveloped.
