The division of the army strives to take care of, via its place of work of Naval study (ONR), a full of life technological know-how and expertise (S&T) software in these components thought of severely vital to U.S. naval superiority within the maritime surroundings, together with littoral waters and shore areas. In pursuing its S&T investments in such parts, ONR needs to make sure that (1) a powerful U.S. examine strength to paintings on long term S&T difficulties in components of curiosity to the dept of the army and the dept of security is continued, (2) an sufficient provide of recent scientists and engineers in those parts is maintained, and (3) S&T items and approaches essential to ascertain destiny superiority in naval battle are supplied. one of many severe components for the dep. of the army is undersea weapons.

An evaluate of Undersea guns technology and Technology assesses the overall healthiness of the prevailing army software in undersea guns, evaluates the Navy's examine attempt to enhance the services wanted for destiny undersea guns, identifies non-Navy-sponsored examine and improvement efforts that would facilitate the advance of such complicated guns features, and makes concepts to concentration the Navy's learn software in order that it will probably meet destiny needs.

Although ONR undersea weapons S&T is tightly coupled to Program Manager, Naval Sea Systems Command (PMS) 404’s road map and so is of necessity evolutionary in nature, the committee observes 1See Appendix B for further details. 24 AN ASSESSMENT OF UNDERSEA WEAPONS SCIENCE AND TECHNOLOGY that some of its components could bring about changes that might be characterized as relatively revolutionary. Specifically, the effort on propulsion energetics that is being pursued at ARL/PSU will, if successful and introduced into operational torpedoes, permit a decrease in the length of a torpedo that is assigned to propulsion.

In addition, the weapon and high-frequency submarine sonar outputs could be processed coherently to enhance passive detection and to perform target localization by estimating the Doppler components and the time difference of arrival. Weapon-Weapon Connectivity The high-bandwidth connectivity between weapon and platform enables another important opportunity. The platform can now act as a node to connect two weapons in the water. The spectral response (or beam aspect, for a monostatic system) of the target gives the best opportunity for detection.

In the case of surface ship defense, weapon guidance is semiactive and a fire control radar is tasked with providing weapon guidance. Decoys may be launched simultaneously in an attempt to spoof the guidance of the incoming missile. If long- and mid-range weapons fail to engage and destroy the incoming missile, close-in weapons are employed. The performance requirements for the analogs of this process for torpedo defense have not been enunciated. What sensors will be used to detect and track the incoming torpedo?
