Variable Depth Sonar

Ultra’s new generation of Variable Depth Sonar (VDS) is a single in-line active-transmit and passive-receive array. In its full specification it can include an active horizontal projector array, a towed low-frequency source, a flexible, towed torpedo acoustic countermeasure body and a directional receive array. Ultra’s fully-modular VDS marks a step change in technology and capability, away from the constraints of traditional towed sonars. It needs only a single, lightweight winch, which can be operated by two personnel. Additionally, the low weight and footprint of the VDS allows it to be fitted to vessels not specifically designed for Anti-Submarine Warfare operations.
