## What project 3301 buys

Improved Capabilities for SPY-1 Radar: These Reliability, Maintainability, and Availability (RM&A) improvements and solid state technology insertions are intended to reduce cascading failures, mitigate obsolescence issues, and improve reliability in support of Anti-Air Warfare (AAW) and Ballistic Missile Defense (BMD) missions while still providing AN/ SPY-1 Radar Total Ownership Cost Reductions. Improvements, such as Solid State Insertion to address Diminishing Manufacturing Sources and Material Shortages (DMSMS), will yield reductions in annual fleet maintenance costs and is a top fleet requirement as part of the AEGIS Wholeness initiative. In addition to RM&A improvements, warfighting improvements funded in this line includes the following: Transmitter Noise Cancellation (TNC) development includes hardware/software to counter low radar cross section, low altitude threats. The Ship-Based Non-Cooperative Target Recognition (SBNCTR) program Phase 2A will develop algorithms to provide classification for targets. Advanced Calibration Experiment (ACE) Phase 2 is being incorporated into Baseline 9. Elevated Radar Advanced Calibration Experiment (ERACE) Backfits and Phase 3 will incorporate into Baseline 9. Electronic Attack (EA) and Rapid Radar Capability Improvement Program (R2CIP) develop solutions for evolving EA threats. The development of MMSP provides simultaneous Anti-Air Warfare (AAW)/Ballistic Missile Defense (BMD) multi-mission capability for DDG 51 class ships as part of the Aegis Modernization Program. This capability is utilized for DDG 113 and follow new construction and Aegis Ashore. Modifies SPY-1D transmitters to enable dual beam for reduced frame times and better reaction times, provides stability for all D(V) waveforms, and avoids operational degradation. The SPY-1 radar system detects, tracks, and supports engagements of a broader range of threats. MMSP improves performance in littoral, ducted clutter, electronic attack (EA), and chaff environments and provides greater commonality in computer programs and equipment. This effort also provides for the development of MMSP-Restoration (MMSP-R) to support system security requirements on Destroyers Commercial Off The Shelf (COTS) refresh and MMSP/MMSP-R technology refresh.

**R-3 lines of work:** Product Development; Management Services.
