Ballistic Missile Defense Sensors
Abstract
The Ballistic Missile Defense System (BMDS) network of layered Sensors provides essential situational awareness and fire control data for the command and control of BMDS weapon systems, such as Ground-based Midcourse Defense (GMD), Aegis Ballistic Missile Defense, and Terminal High Altitude Area Defense (THAAD). The suite of remote ground-based sensors provides early warning, midcourse and terminal ballistic missile defense threat data enabling layered detection and tracking of ballistic missile targets, providing fire-control quality position, velocity, and discrimination data through Ground-Based Midcourse Defense Fire Control (GFC), or Command and Control, Battle Management, Communications (C2BMC). Overlapping coverage of geographically diverse sensors provides improved threat track data, reduces the impact of the loss of any one sensor, and reduces the potential impact of countermeasures. The extended coverage and accuracy provided by a network of layered sensors increases the defensive footprint and reduces the number of target engagements required, thereby conserving interceptor inventory and maintaining a high probability of successful engagement. Networked forward-based sensors enable C2BMC to pair the best sensor coverage with the best available weapon system to provide the most effective defense against ballistic missile threats. This Program Element includes BMDS threat discrimination improvements, which will enhance BMDS effectiveness against the evolving adversary threat. The result will be a BMDS architecture more capable of discriminating and destroying reentry vehicles with a higher degree of confidence, improving Warfighter shot doctrine, and more efficiently using interceptor inventory. BMDS threat discrimination improvements are funded from the Enabling (0603890C), Midcourse (0603882C), BMD Sensors (0603884C), C2BMC (0603896C), and Aegis BMD (0603892C) PEs. The BMD Sensors Program contributes to regional missile defense through the development, delivery and deployment/redeployment of Army Navy/Transportable Radar Surveillance and Control (AN/TPY-2) radars for operations or tests. AN/TPY-2 radars can be configured to operate either as a THAAD Fire Unit Radar (terminal mode) or Forward-Based Radar. These radars are transportable, adding flexibility to respond to geographical changes in threats. Radars provide early warning tracking and discrimination data through all phases of ballistic missile flight. Through the BMDS C2BMC and coalition data links, the AN/TPY-2 provides fire control data to enable remote Standard Missile (SM)-3 engagements by Aegis BMD, to allow earlier engagement by the Arrow Weapon System, and to cue deployed THAAD and U.S. and partner PATRIOT batteries. The BMDS sensor network also includes the COBRA DANE Radar at Eareckson Air Station, Alaska, and the Upgraded Early Warning Radars (UEWRs) at Beale Air Force Base, CA; Fylingdales Royal Air Force, United Kingdom, and Thule Air Base in Greenland. The Clear Ultra High Frequency Early Warning Radar (EWR), at Clear Air Force Station, AK, and the Cape Cod EWR, at Cape Cod Air Force Station, MA, are also being upgraded to include missile defense functionality against long-range threats in addition to their existing Missile Warning and Space Surveillance missions. Upgrade activities began in CY 2012 and are expected to be completed in CY 2017 and 2018 respectively. The addition of the Clear UEWR and Cape Cod UEWRs to the BMDS sensor architecture will improve BMDS sensor coverage and provide new engagement options against long-range missile threats. The Pacific Radar is a new sensor within the Ballistic Missile Defense System that addresses NORTHCOM and PACOM radar requirements for the defense of Hawaii. The Pacific Radar is an long range ballistic missile defense sensor that provides a persistent operational capability for the defense of the Pacific region and improves the discrimination capability to address multiple threats including the no warning strategic challenges of the road mobile ICBM. The radar will leverage development efforts from other sensors projects to reuse discrimination, low elevation acquisition, and tracking algorithms. The Pacific Radar final testing/integration and delivery is planned for CY 2023. Cyber Operations sustains the Risk Management Framework (RMF)and Controls Validation Testing (CVT) activities, analysis of validation results, risk assessments and reviews of Plans of Action and Milestones (POA&Ms) for the Sensors mission system. This Program Element also investigates concepts and performs systems engineering to address hypersonic threats.

- Change Summary Explanation
- The increase from PB17 to PB18 in FY2018 reflects funding for the new Pacific Radar, a long range BMD sensor that addresses NORTHCOM and PACOM radar requirements for the defensive of Hawaii, and studies for a potential Atlantic Radar. The increase also reflects AN/TPY-2 transition to Gallium Nitride (GaN) Transmit/Receive module technology, software improvements to implement C2BMC interface updates, and Objective Debris Mitigation (ODM). Increased funding for Cyber Operations reflects compliance with new Cyber Supply Chain requirements. Also includes reduced contract spending for Mission Support Services in accordance with Department Service Requirement Review Board reductions through increased competition.
