Check Range Sensor Pod

Undersea operational supremacy is foundational to continued U.S. security. This supremacy is partly rendered through clandestine operations. Though Navy submarine and surface ship signatures are measured at land-based silencing facilities or test ranges at sea, these signatures can degrade over time for a variety of reasons, making the platform more vulnerable to detection. Vulnerability levels can be exacerbated if signature degradation occurs. As it is expected that certain missions present high levels of risk, it would be advantageous to create a self-test range at sea rather than transiting to the nearest permanent installation. SeaLandAire Technologies, together with its partners will utilize our extensive experience in expendable Navy sonobuoy platforms to develop an inexpensive, simple, yet highly functional expendable sensor pod to autonomously characterize submarine signatures for increases in in-situ tactical awareness. This in-situ calibration sensor pod will be deployed from a submerged submarine utilizing existing platform capabilities. It will be able to measure underwater magnetic and acoustic fields, with E-fields measured by proxy through their induced magnetic response. The pod will collect meaningful and timely data, while remaining covert.
