INTRODUCTION

This Statement of Objectives (SOO) provides the Government’s objectives for the Clear Radar Upgrade (CRU) program. The CRU program provides for the replacement of the current Ballistic Missile Early Warning System (BMEWS) radars at Clear Air Station (AS), Alaska, with a PAVE PAWS phased-array radar.

  1. BACKGROUND

The BMEWS detection radars and tracking radar currently operational at Clear AS provide tactical warning of intercontinental ballistic missiles (ICBMs) and submarine-launched ballistic missiles (SLBMs) launched from Eurasia and from the Arctic Ocean against North America, in particular, against the CONUS.

The existing BMEWS at Clear AS is obsolete and costly to support. A more modern radar is required to maintain the site’s operational availability requirements in the future and to reduce the annual operations and maintenance (O&M) costs.

In addition, the BMEWS at Clear was fielded in the 1960s; evolution of the threat mandates that the radar sensors be upgraded. Technical improvements provided by phased array radars provide the capability to meet the expected threat.

Air Force Space Command (AFSPC) placed the southern PAVE PAWS sites, located at Eldorado AS, TX, and Robins AFB, GA, into a warm storage mode in 1995. These sites each contain a full complement of prime mission equipment (PME) and support equipment for a two-faced PAVE PAWS radar.

The Air Force has determined that replacement of the existing Clear BMEWS radars with a PAVE PAWS radar will meet the required operational performance and availability.

PROGRAM OBJECTIVES

The overall objective of the CRU program is to replace the existing BMEWS radars at Clear AS with a PAVE PAWS radar, in the most efficient manner possible, using existing Air Force resources when deemed cost effective, and with minimal disruption to operations of the existing Clear radar during construction, integration, and test, while meeting an initial operational capability (IOC) date of January 2001.

The CRU program has been divided into four phases: System Integration Design, Facility Construction, System Integration, and Test and Evaluation. Specific objectives for each of the phases are stated below:

System Integration Design

Adapt the PAVE PAWS design to operate in the environment at Clear AS, so that current PAVE PAWS performance can be achieved. [RM-6]

  1. Design the Clear Radar facility to meet the facility requirements and integrate correctly with the radar prime mission equipment (PME) and support equipment, and document the facility design in a set of design documents. (CDRL “Facility Design Package”)
  2. Ensure that the facility design is adequate for the expected environment at Clear AS, including the effects of arctic conditions, seismic events, ice fog, ionospheric reflectivity, ionospheric scintillation, and polar cap absorption. [RM-19, RM20, RM26]
  3. Ensure that the design is complete in time to order long-lead items for delivery prior to the first construction period. [RM-27]
  4. Facility Construction

Construct a new PAVE PAWS radar facility at Clear AS, using the site-adapted design.

  1. Ensure that the construction is in accordance with the facility design.
  2. Ensure that the construction planning and schedule is appropriate for the short construction seasons, arctic conditions, and remote location found at Clear AS. [RM26]
  3. Ensure that all required environmental and construction permits and approvals are obtained in time to avoid delays to IOC.
  4. Ensure the safety of workers from hazards due to construction or due to operation of the existing radar (i.e., radiation hazards) while the new radar facility is being built. [RM-3]
  5. Provide facility “as-built” documentation and real property installed equipment (RPIE) manuals so that proper operations and maintenance of real property and RPIE can be performed by the Government after IOC. [RM-28] (CDRL “As-Built Drawings” & “RPIE Manuals”)
  6. System Integration

Integrate the PAVE PAWS radar PME into the new radar facility at Clear AS, using the site-adapted design.

Equipment Reuse

Define and implement a cost-effective approach to reusing existing PAVE PAWS equipment from the southern PAVE PAWS sites.

  1. Ensure that the southern PAVE PAWS sites retain the ability to reconstitute an operational capability within nine months for single-face operation and 24 months for two-face operation. [RM-10]
  2. Ensure that any reused equipment from the southern PAVE PAWS sites is safely removed, packaged, and transported to and stored at Clear AS. [RM-4, RM23]
  3. Ensure that the equipment reuse approach mitigates problems resulting from existing PAVE PAWS equipment that is found to be unavailable, unsupportable, or unacceptable for use during removal at the southern sites or integration and test at Clear AS. [RM-1, RM5]
  4. System Engineering

Perform the necessary system engineering tasks to ensure that the upgraded Clear radar meets its requirements and is fully operational by the IOC date.

  1. Using the Government-provided CRU Technical Requirements Document and the existing PAVE PAWS System Performance Specification, define the required performance for the upgraded Clear radar and provide appropriate changes to the existing PAVE PAWS specifications and other configuration documentation. (CDRL “Specification Change Notices” & “Product Drawings and Associated Lists”)
  2. Ensure that the radar design is adequate for the expected environment at Clear AS, including the effects of arctic conditions, seismic events, ice fog, ionospheric reflectivity, ionospheric scintillation, and polar cap absorption. [RM-19, RM20, RM26]
  3. Ensure that the design of the upgraded Clear Radar and its facility will allow safe operation and minimize electromagnetic interference to the surrounding community. [RM-3]
  4. Ensure that proper hazardous materials planning and reporting is performed in accordance with applicable environmental statutes. (CDRL “Hazardous Materials Management Program Plan” & “Hazardous Materials Management Program Report”)
  1. Installation/Integration

Ensure that all PAVE PAWS subsystems and configuration items are properly integrated with the radar facility and other Clear AS facilities. [RM21]

  1. Ensure that the upgraded Clear Radar properly interfaces with the communications facilities that will be operational at Clear AS at the IOC date. [RM-11, RM-16]
  2. Implement the required hardware and software changes required to meet the site-adapted design.
  1. Logistics

Augment the current PAVE PAWS logistics infrastructure as required to ensure the upgraded Clear Radar is fully supportable at the IOC date.

  1. Identify, recommend, and provide any needed support equipment for RPIE and PME that is unique to the upgraded Clear Radar. (CDRL “Support Equipment Recommendation Data”)
  2. Identify any new spares which are unique to the upgraded Clear Radar, and provide recommended quantities sufficient for a two-year period following IOC. [RM-24] (CDRL “Recommended Spare Parts for Spares Acquisition Integrated with Production”)
  3. Identify any necessary changes to the current PAVE PAWS training program and provide recommended changes to the Government, including updates to existing PAVE PAWS training materials. (CDRL “Training Material Change Package”)
  4. Provide change pages to existing PAVE PAWS technical manuals and existing commercial off-the-shelf (COTS) manuals to include supplements to both RPIE and PME manuals where required by upgraded Clear Radar configuration. (CDRL “Publication Correction Instructions”)
  5. Test and Evaluation

Conduct a test and evaluation program to ensure that the upgraded Clear Radar meets all requirements and is ready for operational use. [RM-9]

  1. Define a test strategy that accounts for the environment at Clear AS, including the impact of aurora. [RM-2]
  2. Define a test strategy that requires acceptance testing on complete subsystems, not on separate components.
  3. Verify during Qualification Test and Evaluation (QT&E) that the upgraded Clear Radar meets all requirements of the updated PAVE PAWS System Performance Specification, through a combination of tests, demonstrations, inspections, and analyses. (CDRL “Test Plan/Procedures/Report”)
  4. Support and correct deficiencies found during the Air Force’s CRU operational testing, which demonstrates the operational effectiveness and suitability of the upgraded Clear radar.
  5. Provide corrections for deficiencies found during the CRU Trial Period.
  1. Management

Manage the CRU program using a disciplined management system to deliver the upgraded Clear Radar within budget and no later than the required IOC date. [RM-23]

  1. Provide management controls to ensure that communication and coordination with all subcontractors and vendors is effective. [RM-8, RM-13, RM-26]
  2. Negotiate appropriate associate contractor agreements to ensure proper coordination with other contractors providing products and services for CRU, such as the Training System contractor. [RM-25, RM26]
  3. Provide the Government with insight into the program’s progress against the baselined schedule and budget. (CDRL “C/SSR” & “Integrated Master Schedule”)
  4. Ensure that the program minimizes the impact to operations of the existing Clear radar through proper planning and use of AFSPC and site planning processes. [RM-15]
  5. Ensure that the Government has visibility into and access to internal data generated by the contractor in performance of the CRU program. (CDRL “Data Accession List”)
  1. Treaty Compliance

Following IOC of the upgraded Clear radar, dismantle the existing BMEWS radar antennas. [RM-12] (CDRL “Radar Dismantling Report”)
