COMINPAC has recently conducted a short series of tests to determine the submarine classification capability of the small boat AN/SQS-19 sonar (high resolution minehunting son ar) presently installed on the USS COVE (MSI). The purpose of the tests was to demonstrate submarine classification by means of visual aspect as well as aural Doppler modulation produced by the submarine's propellers on the FM sonar target echoes. The test results were sufficiently successful that ADM Veth, COMINPAC, suggested to ADM Thach, ASWFORPAC, during a meeting of their combined staffs in Long Beach, California on 16 March, that such a device installed on a helicopter might be useful to ASWFORPAC. As an attendee at that meeting, I was requested to comment briefly on the technical feasibility of such an installation, and to present any background information pertinent to the suggestion. Later I was requested by ADM Thach and staff to forward to their headquarters the following information: (a) Tape recordings of actual runs on submarines which would demonstrate the type of propeller Doppler modulation to be expected; and (b) A proposal outlining how a helicopter might be effectively equipped with such a sonar givin size, weight, speed, cost, etc. This proposal, although somewhat delayed due to press of other business, fulfills that request.
