Description: PE 1203873F BALLISTIC DEFENSE RADARS - Radar Due to obsolescence of unsupportable mission and capital equipment and Initial spares, coupled with the lack of vendors, COBRA DANE faces a critical parts shortage. Procurement of these parts are critical to maintain operational access and sustainment of the COBRA DANE radar residing on Shemya Island,AK.

PE 1203909F BALLISTIC MSL EARLY WARNING SYSTEM (BMEWS) - P-40A PE 1203909F The Early Warning System (BMEWS) is a ground based radar system with missions to support the Missile Correlation, Space Surveillance, and Centers. The BMEWS radars provide United States Strategic Command (USSTRATCOM) with credible Integrated Tactical Warning/Attack Assessment (ITW/AA) data on all Inter-Continental Ballistic (ICBMs) and Sea-Launched Ballistic Missiles (SLBMs) penetrating the coverage area including Launch and predicted impact (L&PI) data for attack assessment and response determination. BMEWS also supports the Space Situational Awareness (SSA) network providing near-earth satellite surveillance and tracking, reporting observational (metric), SOI on man-made satellites and maintenance of the space catalog as required by the Joint Space Operations Center, Alternate Space Operations Center, and the National Air and Space Intelligence Center mitigating the significantly increasing potential for collisions with national assets, including manned space platforms. The BMEWS shares a common baseline and mission with the PAVE Phased Array Warning System (PAVE PAWS) while deploying more array elements on its faces. The Upgraded Early Warning Radar (UEWR) sites at Thule and Fylingdales also have a Missile Defense (MD) mission supporting the Missile Defense Agency. These radars are located at Thule Air Base, Greenland; Clear Air Force Station, AK; and Royal Air Force (RAF) Fylingdales, UK. Additionally there is a site for testing (System Program Agency) located in the Centralized Integration Support Facility (CISF) at Peterson AFB, CO.

PE 0305114F - Air Traffic Control and Landing Systems (ATCALS). ATCALS procures and supports fixed-base and tactical radar, navigation aids, voice communications, and data processing/automation capabilities which enable Air Force (AF) air traffic controllers to provide advisory, sequencing, separation, and landing guidance services to all aircraft in AF-assigned airspace. In support of Global Mobility, Agile Combat Support, Global Strike, Homeland Security, and Global Response concepts of operation, ATCALS centrally manages the Air Force's air traffic control capability to ensure air traffic control facilities/ equipment can safely and expeditiously support en route an terminal operations in benign and combat areas of responsibility. ATCALS modification efforts maintain system reliability and supportability of legacy until replaced by new technology or next generation of equipment.

PE 0305137F - National Airspace System (NAS). NAS is a program which entered full rate production in 2005 and is now in the operations and support phase. NAS modernizes the Department of Defense (DoD) air traffic control (ATC) system in concert with the Federal Aviation Administration (FAA) Modernization effort. The FAA is the overall NAS program lead and the Air Force is the DoD lead. Equipment procured includes ATC automation systems, surveillance radars, voice switches, voice recorders, and other ancillary equipment. As the program is now in the sustainment phase, main focus in on reliability and maintainability upgrades, ensuring compliance with the FAA maintained standard system configuration, and incorporation of low cost modifications as required.

Description: The Gen 4 equipment and ATC Surveillance Radar upgrades are being procured as a centrally managed commodity as part of the National Airspace System (NAS). NAS Gen4 (software/hardware) and surveillance radar system configurations are centrally maintained and certified by the Federal Aviation Administration which has system engineering responsibility for the NAS. The (NAS) Gen 4 Modification continues mitigation of diminishing manufacturing source issues for the NAS program which has transitioned to the Operational Support Phase. Over its 15 year production/implementation phase, NAS was fielded in multiple hardware configurations and software builds. Current NAS processors and associated network equipment have gone end of life. The NAS Gen4 equipment and Standard Terminal Automation Replacement Systems (STARS) interface to Digital Airport Surveillance Radar (DASR) modification establishes standard radar hardware and software configurations and ensures continued system supportability and availability. Configuration consolidation also reduces multiple, simultaneous efforts associated with system hardware and software upgrades and test while reducing cost outlays.

JUSTIFICATION:

FY19 funds will procure 2 upgrade kits (2 AD/0 ANG/0 AFR).

Milestone/Development Status

Modification kits have already been kit proofed by FAA and are available off FAA contract.

Footnotes: (1) Unit cost in FY17 is lower than unit cost in FY18 through FY19 as FY17 kits are for 4 Enhanced Local Integrated Tower Equipment (ELITE) mod kits which is a smaller system than the Gen 4 system kits being procured in FY18/19 for the much larger radar approach control facilities.
