Abstract:

This report covers the experimental work and service tests performed in the development of the False Target Shell FTS Mark I. This device, on ejection from a submarine, is designed to generate a bubble cloud serving as a false target for submarine echo-ranging attack. It is suitable for training of sound operators as well as for submarine evasion. Information from the Commanding Officer of the USS SEMMES concerning the deep water tests of the False Target Shell at Portsmith, N. H. on April 17, 1943 arrived after publication of this report. This information 1. Bibliography concurs with that given in the report. Successful prosecution of this problem was made possible by the cooperation of officers and civilians of the Sound Division.
