Check-Range Sensor Pod (CRSP) is a low-cost, expendable sensor system to measure submarine acoustic and electro-magnetic (EM) signatures at depth in forward areas. Although CRSP’s measurement capabilities are not as extensive as existing test ranges, the ability to perform the characterization in the field represents a significant increase in operational flexibility and capability. Intended for use throughout the submarine force, initial deployment will focus on the Ohio and Virginia classes. Phase II prototype testing is underway to demonstrate the feasibility of the CRSP concept, after which SeaLandAire and its partners will focus on integration, production, and transitioning the technology to the fleet. SeaLandAire Technologies is a small business focused on research and development of autonomous sensor platforms particularly expendable sensors for underwater applications.
DDEMS (Deep Drifting Environmental Measurement Sonobuoy) is an A-size long life, test and engineering measurement sonobuoy supporting development and evaluation of technology components for the deep drifting sonobuoy being developed by the NGAPS (Next Generation Airborne Passive System) FNC program. DDEMS features the ability to deploy sensor payloads to a deep depth in the ocean and collect broad bandwidth data from the sensors. This data is then relayed via a high data rate fiber optic cable to a surface unit containing an RF radio link for easy data collection in a real time or at a time late data recall mode. While needed by the NGAPS FNC program, DDEMS is also a unique sonobuoy vehicle to support cost effective deep depth ocean measurements using a variety of sensor payloads.
SeaLandAire Technologies, specializing in rapid development of advanced engineering solutions in a broad range of applications, is developing the Digital DIFAR Vertical Line Array (DDVLA) sonobuoy to complement the U.S. Navy’s emerging technologies in low frequency sonar detection. The buoy utilizes a vertical line high-gain array of miniaturized directional detectors for a high signal-to-noise ratio in noisy environments. DDVLA will be used in aircraft-based Anti-Submarine Warfare (ASW) operations as part of a growing family of low-frequency sonobuoy systems. Initial prototypes of the acoustic system show promising results, and leverage SeaLandAire’s experience in sonobuoy development. The end objective of this Phase II is to have a field-proven buoy system design that can then be moved to production and qualification, with the assistance of a transition partner.
