By National Research Council, Division on Engineering and Physical Sciences, Mathematics, and Applications Commission on Physical Sciences, Naval Studies Board, Committee for Undersea Weapons Science and Technology

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

An overview of Undersea guns technological know-how and Technology assesses the healthiness of the present military application in undersea guns, evaluates the Navy's examine attempt to boost the features wanted for destiny undersea guns, identifies non-Navy-sponsored study and improvement efforts that may facilitate the improvement of such complex guns features, and makes suggestions to concentration the Navy's study application in order that it could actually meet destiny needs.

Example text

Bottom transponders could act as two-way store-and-forward communication links by communicating acoustically with sonobuoys that could link via satellite communication or line of sight to receivers at a command and data fusion center aboard ship. In this way, UUVs could be directed to a different search area, overridden, or recalled at any time. Similarly, UUVs could send status and mission data back to the command ship. Presumably the sonobuoys would also be used to receive data from the distributed arrays in locales where fiber-optic links to the command center are either inappropriate or unsustainable.

26 AN ASSESSMENT OF UNDERSEA WEAPONS SCIENCE AND TECHNOLOGY communication technology, which is being developed under ONR 32 sponsorship, offers the opportunity for relatively high bandwidth connectivity that can be synergistically deployed with or added to the arrays. The challenge of effectively confronting submarines in the littoral environment is not being addressed on the basis of a complete analysis and understanding of the physics involved. Acoustic methodology has long been the primary means of underwater communication and target identification and location, and the Navy has consistently been a leading performer in this area.

The DARPA effort is based on the concept that success in future undersea warfare (particularly in littoral regions) will involve the use of networked sensors and weapons. ” Quantitative operations analysis applied in this area, as in others, could assist in comparing the payoffs of different systems and CONOPS. In summary, interactions with related technology areas need strengthening. The committee believes that establishing more useful interactions between the management of the ONR undersea weapons S&T program, the DARPA undersea warfare program, and the ONR antisubmarine warfare S&T program would result in a more modern and forward-looking approach to undersea weapons research.
