An evaluation of the USNS HAYES as a towing platform for the TTUMSTransportable Towed Underwater Measurement Unit or other towed array was performed as one of three evaluations to determine HAYES suitability as a replacement for MONOB. Of primary concern was the possibility that HAYES motion might impart unacceptably large motions to the TTUMS array. An experiment was performed in which USNS HAYES towed the TARP array, configured to simulate TTUMS. Both TARP and the USNS HAYES were instrumented to permit track and motion measurements on the AUTEC Weapons Range. The array generally towed straight and horizontally with a maximum deviation of 1.5 degrees from a straight line. The typical maximum transverse velocity was 0.1 msec. Array handling was performed without difficulty. It was concluded that, from the aspect of a towing platform, the USNS HAYES would be capable of satisfactory performance in replacing MONOB for the TTUMS mission.
