(U) MISSION DESCRIPTION AND BUDGET ITEM JUSTIFICATION: This program supports innovative research and development in submarine technologies and the subsequent evaluation, demonstration, and validation for submarine platforms. It will increase the submarine technology base and provide subsystem design options not currently feasible.

(U) Project S2033 identifies the most promising and emerging technologies and transitions them into specific demonstration/validation efforts. The project transitions technologies developed by Navy technology bases, the private sector, and the Defense Advanced Research Projects Agency (DARPA) Tactical Technology Office. Advanced systems developed under this program have potential for backfit into existing classes of submarines, supporting emerging requirements, and systems technology insertion into future submarine designs. Research and development (R&D) investment factors used to select these technologies include: economic environment and return on investment; mission enhancement; and safety and survivability. The project also conducts an SSN Security Program (SSP) to develop techniques and devices that decrease the detection vulnerability of attack submarines, specifically operating in littoral environments; supports two Information Exchange

Programs with the United Kingdom (UK), one on submarine electromagnetic silencing and the second on submarine platform equipment, systems and hull technology; operates the Large Scale Vehicle (LSV) to provide at-sea test capability for propulsor, acoustic and non-acoustic signature reduction, remote vehicle R&D, and large scale hydrodynamic experimentation; operates the Integrated Measurement System (ISMS) in support of structural acoustics technology development; operates the

Hydrodynamic/Hydroacoustic Technology Center (H/HTC) to enhance our ability to accurately, computationally predict hydrodynamic and hydroacoustic performance of submerged bodies; and provides life cycle support for the R&D Submarine modifications.

(U) Project S2034 provides resources to convert an attack submarine to a dedicated R&D platform without loss of mission capability. This project provides a dedicated at-sea platform for testing and evaluating advanced systems technologies applicable to existing and the next generation SSN.

(U) Project F2177 is dedicated to the New Attack Submarine (New SSN). The primary goal of the project is to develop affordable yet capable submarine platform specific systems by evaluating a broad range of system technology alternatives and examining cost reduction, producibility improvement, and technical risk reduction.

(U) JUSTIFICATION FOR BUDGET ACTIVITY: This program is funded under DEMONSTRATION & VALIDATION because it develops and integrates hardware for experimental tests related to specific ship or aircraft applications.
