The division of the military strives to keep up, via its workplace of Naval learn (ONR), a lively technological know-how and expertise (S&T) application in these parts thought of severely very important to U.S. naval superiority within the maritime surroundings, 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. learn potential to paintings on long term S&T difficulties in parts of curiosity to the dep. of the military and the dept of safeguard is continued, (2) an enough offer of latest scientists and engineers in those parts is maintained, and (3) S&T items and methods essential to make certain destiny superiority in naval battle are supplied. one of many serious components for the dept of the military is undersea weapons.
An overview of Undersea guns technological know-how and Technology assesses the overall healthiness of the present army software in undersea guns, evaluates the Navy's study attempt to advance the services wanted for destiny undersea guns, identifies non-Navy-sponsored learn and improvement efforts that would facilitate the improvement of such complicated guns services, and makes innovations to concentration the Navy's examine application in order that it could meet destiny needs.

The need for S&T is a constant, and ONR must maintain a reservoir of S&T from which it can draw for weapons development. As discussed below, the committee believes that S&T needs to go beyond the torpedo in its present or upgraded form. 4 Acoustic 3The Navy master plan road map (see Appendix A) indicates an insertion of this technology as an MK-54 product improve- ment in 2001. 4At the present time, the advanced deployable system requires a cable termination on a friendly shore. 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.
With broadband sensors and processing implemented on each weapon, an attack could be prosecuted wherein each weapon operates monostatically in its own band and bistatically in the band of the coordinating weapon. In this way, search geometries could be devised and would regain much of the robustness provided by the receipt of spectral returns. In addition, with fiber-optic connectivity, the weapons could share raw data, leading to large baseline coherent processing 18 AN ASSESSMENT OF UNDERSEA WEAPONS SCIENCE AND TECHNOLOGY between them and three-dimensional imaging possibilities.
TECHNOLOGY ISSUES Maturity of the Key Technology Areas and Associated Challenges As presented to the committee, the ONR undersea weapons S&T program is largely devoted to developing incremental improvements that can be inserted into either or both the MK-48 and MK-50 torpedoes. In the case of the MK 50, the plan is to retrofit with MK-46 open-cycle engines and replace the directed-energy warhead with a bulk charge. The MK 50 has a SCEPS engine that will be replaced with an MK-46 engine in the MK 54.
