INTRODUCTION
This Statement of Objectives (SOO) provides the Governments
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.
- 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The existing BMEWS at Clear AS is obsolete and costly to support.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 sites 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]
- 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)
- 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]
- Ensure that the design is complete in time to order long-lead
items for delivery prior to the first construction period. [RM-27]
- Facility Construction
Construct a new PAVE PAWS radar facility at Clear AS, using the
site-adapted design.
- Ensure that the construction is in accordance with the facility
design.
- Ensure that the construction planning and schedule is appropriate
for the short construction seasons, arctic conditions, and remote
location found at Clear AS. [RM26]
- Ensure that all required environmental and construction permits
and approvals are obtained in time to avoid delays to IOC.
- 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]
- 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)
- 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.
- 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]
- 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]
- 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]
- 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.
- 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)
- 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]
- 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]
- 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)
- Installation/Integration
Ensure that all PAVE PAWS subsystems and configuration items are
properly integrated with the radar facility and other Clear AS
facilities. [RM21]
- 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]
- Implement the required hardware and software changes required
to meet the site-adapted design.
- Logistics
Augment the current PAVE PAWS logistics infrastructure as required
to ensure the upgraded Clear Radar is fully supportable at the
