New 'Mosquito Boat' ready for action. Washington, D.C., June 19. The PT-9, first of the American Motor Torpedo Boats to be delivered to the U.S. Navy under the President's $15,000,000 experimental small craft program had a preview showing for the press today. The 'Mosquito Boat' and eight other ones will be based at the naval operating base, Norfolk, Virginia, where they will undergo service tests under various sea conditions to determine their capabilities and limitations. This is the same type of boat that the government is in the process of releasing to the British Navy. Chairman David L. Walsh of the Senate Naval Affairs Committee expressed indignation over the Navy's action in this respect in view of the fact that this government is trying to build up its own sea power
