No. 874. From Vice Admiral Sims for Secretary of Navy. Mystery ships are of little use without motive power. In any case they must stimulate <simulate> merchantmen perfectly in rig and all respects and should be as nearly unsinkable as possible. The great need for any type craft which can keep sea and carry gun and radio. The need is immediate. Losses are not decreasing while demands on anti-submarine craft are steadily increasing. Numbers of craft are the necessities of the situation.
