An underwater disruptor comprises a water tight chamber formed by a modified housing, a modified breech, and a modified backplate sealed together by a plurality of O-rings. The underwater disruptor is configured to discharge a firing pin to shoot a water bullet from the modified barrel at a specific underwater explosive threat responsive to receiving a fire command from a remote operator. The water bullet is formed from water ejected from the barrel due to the discharge. The underwater ROV physically hosts the underwater disruptor and is configured to provide video feedback during underwater travel remotely to the specific underwater explosive and to activate shooting of the water bullet responsive to the fire command.

Wind for speed, direction, and temperature measurement is passed along a plane. A sound wave generating transducer (speaker) is addressed to the plane. At least two, and preferably three sound wave receiving transducers (microphones) surround the sound wave generating transducer and are preferably located on the plane. A phase locked loop circuit maintains the same sound wave length between the sound wave generating transducer and one fiducial sound wave receiving transducers. By noting differing phase of sound wave at the two remaining sound wave receiving transducers, temperature compensated wind speed and direction can be determined. Additionally, and with the input of the change of frequency necessary to maintaining the same sound wave length between the sound wave generating transducer and the one fiducial sound wave receiving transducer, temperature of the passing air can be determined. In the preferred embodiment, a sound reflector plane overlies and underlies the plane within which the wind to be measure passes. This latter configuration decreases instrument sensitivity to surrounding obstacles. A highly accurate, durable, compact and temperature insensitive sonic anemometer/thermometer is disclosed.
