Radar Development

Radar Development under the Army's Research, Development, Test & Evaluation (RDT&E) budget activity, aims to support the Sentinel Radar program and provide an incrementally fielded Integrated Air and Missile Defense Fire Control System for the composite Army Air and Missile Defense Brigades. The program's specific objectives include the development of Sentinel A4, an advanced three-dimensional battlefield X-Band air defense phased-array radar with an instrumented range of 75 kilometers. This radar system is designed to automatically detect, classify, identify, and report targets such as cruise missiles, unmanned aircraft systems, rotary wing and fixed-wing aircraft. Additionally, the program focuses on enhancing survivability, resiliency, and effectiveness against advanced threats from near-peer adversaries through integration with common fires mission command and annual test and evaluation efforts.

The funding for FY 2024 will be utilized for Defense Guam in support of the Pacific Deterrence Initiative. The program aims to integrate five Initial Operational Test and Evaluation (IOT&E) systems and develop additional survivability enhancements for inclusion into Sentinel A4. It also includes efforts to enhance the Sentinel A4 configuration to support Defense of Guam mission set to enable fielding in-country by requested timelines. Furthermore, the program will continue to build and integrate five IOT&E assets for delivery in support of system IOT&E while addressing electronic countermeasure gaps through Electronic Attack/Electronic Protect (EA/EP) efforts. These initiatives align with the broader goal of contributing sensor support for mitigating current and future Indirect Fire Protection Capability Increment 2 mission requirements as well as Mobile Short Range Air Defense (M-SHORAD) battalions.
