New Mosquito Boat gets a tryout. Washington, D.C., June 19. The PT-9, first of the new 'Mosquito Boats' to be delivered to the U.S. Navy under the President's $15,000,000 experimental small craft program had a preview for the press today. This is the same type of boat that the government is in process of releasing to the British Navy, causing great unrest and indignation in Capitol circles. Eight other boats will be based at the naval operating base, Norfolk, Virginia, to undergo severe seagoing tests. The squadron will be known as the Mosquito Fleet and the insignia which was designed by Walt Disney consists of a mosquito riding on the top of a high speed torpedo. Shown in the picture is Lieutenant Earl S. Caldwell, USN, Commander of the squadron
