Ballistic Missile Defense Mid-Course Segment
Abstract
To counter the Intercontinental Ballistic Missile and Intermediate Range Ballistic Missile threat, the United States deploys Ground-Based Midcourse Defense (GMD) interceptors in silos at Fort Greely, Alaska (FGA) and Vandenberg Air Force Base, California (VAFB) to defend our Homeland from Intercontinental Ballistic Missiles or Intermediate Range Ballistic Missile attack. In Fiscal Year 2010, we will continue the development of long-range Ground-based Midcourse Defense capabilities with missile fields at Fort Greely, Alaska and Vandenberg Air Force Base, where we will maintain 26 and four Ground-Based Interceptors (GBI), respectively. This work will improve protection of the United States against a limited number of rogue state launches of Intermediate Range Ballistic Missiles s and Intercontinental Ballistic Missiles s. Given the small inventory of long-range ballistic missiles deployed by rogue states, thirty highly-ready Ground Based Interceptors in hardened silos will provide the United States substantial fire power. Ballistic Missile Defense Systems engineering provides System Description Documents and System Specifications for elements to design, build, integrate and test Ballistic Missile Defense System components. These products optimize performance at the system level and further ensure that the assessment of the designed Ballistic Missile Defense System is based on sufficient flight tests, ground tests, modeling and simulation, and engineering analysis. Compliance of Ground Based Midcourse Defense to Ballistic Missile Defense System level requirements is monitored in a series of requirements and design reviews both at the system and element levels. The Ground Based Midcourse Defense capability requires quality of service from other Ballistic Missile Defense System elements such as Sensors, Aegis, and Command & Control, Battle Management and Communications to enable successful ballistic missile engagements to protect the U.S. Homeland. This includes the following data: accurate object location tracks and classification/discrimination from radar sources such as Sea-Based X-Band radar and Upgraded Early Warning Radars (UEWR) at Beale, Fylingdales, and Thule. Also on forward deployed radars such as Army Navy/Transportable Radar Surveillance and Aegis, object location track information is required from Command & Control, Battle Management and Communications which provides additional time for the Warfighter to plan defense engagements. Missile Defense Agency has a set of Unifying Missile Defense Functions, which increase the effectiveness of the Ballistic Missile Defense System (including probability of engagement success, increase in defended area and raid size capacity, additional redundancy of architecture, unity of command) through the integration of Missile Defense Agency developed capabilities. These Unified Missile Defense Functions efforts are Sensor Registration (reporting of sensor errors / biases), Correlation (ensuring the information from multiple sensors seeing a threat relates to the same object), System Track (creating a single engageable track of a threat from multiple reports provided by different land, sea, and space based multiple sensors), Discrimination (identifying object details to determine the target from debris or decoys), Battle Management (combining the best sensors and shooters to ensure the highest probability of a kill), Hit / Kill Assessment (determining if the target selected was destroyed after missile impact), and Communications (providing the worldwide connection of sensors and shooters to command authorities). Unified Missile Defense Functions are implemented across the Ballistic Missile Defense System elements to create and utilize system level data and decisions that allow Combatant Commanders the ability to automatically and manually optimize sensor coverage and interceptor inventory to defend against all ranges of ballistic threats. Common Threat Engineering produces common and consistent adversary trajectory and signature data to enable Ballistic Missile Defense System and sub-system concept and requirements, design, verification, and assessment. Common threat data is contained in the Adversary Capability Document (ACD) and Adversary Data Packages (ADP) and drives Ballistic Missile Defense System ground tests, flight tests, digital simulations, and pre-mission analysis activities. It is also used to develop the Ballistic Missile Defense System Description Document and Ballistic Missile Defense System Specification. Modeling and simulation (M&S) activities support all phases of Ground Based Midcourse Defense development, including development of modifications to the Ground Systems and Ground Based Interceptor development, flight test missions, ground tests, war-games, exercises, and performance assessment. Models and simulations are tailored to the specific need of a component in its current phase of development, ranging from low-to-medium fidelity analyses supporting concept definition studies, to high-fidelity models used to support engineering development, or testing and are integrated into the Ballistic Missile Defense Digital Simulations Architecture. Digital simulations support Performance Assessment events, which provide critical system level performance data relative to all elements, the system engineer, Models and Simulations developers, Operational Test Agency (OTA) and the Warfighter. Further, the Models and Simulations digital tools are accredited for each application and for specific objectives; tools are put through a rigorous verification and validation process, reviewing coding and specifications, and comparing analyses against actual flight test results. Planning support is required to assist in the V&V plan development, test execution, analysis for Verification and Validation (V&V) reports and program office Models and Simulations certification. The Digital End-to-End simulation of the Ballistic Missile Defense System requires a Performance Assessment (PA) Integrated Verification & Validation (V&V) Plan and Report (at both element and system level), and a PA-system level Accreditation Plan and Report. Ground Based Midcourse Defense Element consists of a complex communications system, fire control capability, and ground-based interceptors. The Ground Based Midcourse Defense element is a key component of the Ballistic Missile Defense System, providing Combatant Commanders capability to engage ballistic missiles in the midcourse phase of flight. This phase, compared to boost or terminal, allows significant time for sensor viewing from multiple platforms and thus provides multiple engagement opportunities for hit-to-kill interceptors. Ground Based Midcourse Defense provides the capability to engage and destroy long-range threats in the midcourse battle space to protect the U.S. Homeland. The Ground Based Midcourse Defense program is described as follows: Ground Based Midcourse Defense capability consists of communications systems, fire control capabilities, and ground-based interceptors. We will continue the development and fielding of the Ground Based Midcourse Defense capability to defend the U.S. against a limited number of rogue state launches of Intermediate-Range Ballistic Missiles and Intercontinental Ballistic Missiles. To prove the Ground Based Midcourse Defense capability works, we will execute a rigorous test program that includes expanding our flight and ground test programs to test our capability against intermediate and long-range threats to build the confidence of U.S. and allied stakeholders in the Ballistic Missile Defense System, bolster deterrence against their use, and send a powerful message to potential adversaries looking to acquire ballistic missiles. We will continue to provide for the operations and sustainment of Ground Based Midcourse Defense fielded capability at Fort Greely, Alaska, Vandenberg Air Force Base, the Missile Defense Integration Operations Center (MDIOC), and across the nation-wide Ground Based Midcourse Defense Communications Network. Ground Based Midcourse Defense will pursue a competitive Development and Sustainment Contract (DSC) for future development; fielding; test; systems engineering, integration and configuration management; equipment manufacturing and refurbishment; training; and operations and sustainment support for the Ground Based Midcourse Defense system and associated support facilities. We will continue execution of a lifecycle management plan to sustain the Ground Based Midcourse Defense system through 2030 and beyond. To increase reliability of the Ground Based Interceptor fleet we will rotate newer Ground Based Interceptors into operational fleet and refurbish older Ground Based Interceptors for flight testing and operational spares. To improve the reliability of Ground Based Midcourse Defense Ground Systems, we will execute an obsolescence and technology refresh program for Ground Systems components to mitigate obsolescence issues. To improve the reliability of Ground Based Midcourse Defense Ground Systems, we will complete Missile Field 2 (MF2) at Fort Greely, Alaska and plan for the decommissioning of Missile Field 1 (MF1). We will execute an obsolescence and technology refresh program for Ground Systems components to mitigate obsolescence issues.
