News that Lockheed Martin had successfully mated the spacecraft bus
and the payload for the first Space Based Infrared System (SBIRS)
geosynchronous orbit (GEO) satellite was overshadowed by a scathing new
report on the troubled programme from the GAO. The report notes that
"Since its inception, SBIRS has been burdened by immature
technologies, unclear requirements, unstable funding, underestimated
software complexity, poor oversight, and other problems that have
resulted in billions of dollars in cost overruns and years in schedule
delays."
SBIRS is intended to provide early warning of ballistic missile
launches and support other missions simultaneously, including missile
defense, technical intelligence and battlespace awareness. The programme
was initially launched in 1996, at which time the DoD expected to field
SBIRS by 2004 at a cost of about $4.2 billion. However, over the past 11
years, SBIRS has proven to be technically challenging and substantially
more costly. In an effort to stem cost increases and schedule delays,
DOD has restructured the programme multiple times, including revising
programme goals. SBIRS is now estimated to cost over $10.4 billion, and
the first satellite launch is expected in 2008. Because of continuing
problems with SBIRS, DOD began a parallel alternative effort in 2006
known as the Alternative Infrared Satellite System (AIRSS), to compete
with SBIRS and ensure that the nation's missile-warning and defense
capabilities are sustained, or possibly provide a follow-on capability
to SBIRS.

The GAO report concludes that, although the Air Force has acted to
reduce risks in the SBIRS programme and has had some recent successes,
the programme still faces risk of not delivering promised capabilities
within its revised goals. To reduce risk, the SBIRS program cut back on
quantity and capability in e face of escalating costs. It deferred
capabilities, such as mobile data processors for the Air Force and the
Army and a fully compliant backup mission control facility, and it
pushed off a decision to procure the third and fourth satellites. The
Air Force also concurrently initiated AIRSS as a secondary means of
achieving the same capability. However, about 11 months after the most
recent SBIRS restructuring, a November 2006 assessment report by the
Defense Contract Management Agency (DCMA) showed that some efforts
within the programme were experiencing significant cost increases and
schedule overruns and that the outlook is worsening. Furthermore, the
programme is rapidly spending its management reserves--funds set aside
to address unexpected problems.
The GAO comments that the Air Force has not positioned the AIRSS
program for success. First, not enough time is budgeted for developing
and launching the first satellite--only 12 months from preliminary to
critical design review, and 4 years from critical design review to
satellite delivery. Second, the AIRSS program may be optimistic in its
assumptions about technology/ risk, since it is working to build an
infrared telescope with a large viewing capability that has never before
been developed and it is planning to use "cryocoolers" that
have yet to demonstrate low levels of jilter, high efficiency, and long
life, and a sensor chip whose assembly s performance level has yet to be
verified.
Third, the Air Force's research laboratory officials have
stated that on-orbit testing is the only way to validate the proposed
capability for AIRSS and reduce risk to an acceptable level. To achieve
these results, the Air Force is proposing to launch a small-scale
demonstration satellite in late 2010. However, the results from the
on-orbit demonstration satellite will not be ready in time to fully
inform the development of the first AIRSS satellite. Furthermore, AIRSS
officials plan to award contracts for the first satellite before data
from on-orbit testing is completed.
The report concludes that SBIRS continues to face risks that
endanger DOD s ability to sustain, replace, and expand its current
missile-warning and defence capabilities. Moreover, the programme still
has complex and difficult work ahead as it undertakes efforts to
integrate technology. Recognizing these risks, the Office of the
Secretary of Defense made a sound decision in pursuing the AIRSS
programme to act as an alternative to the third SBIRS GEO satellite.
However, the programme has since diverged from this purpose and opted to
pursue a higher-risk effort in order to advance capability. Moreover,
the Air Force has added risk to this effort by compressing the schedule
and limiting the knowledge gained from the demonstration effort. While
it is acceptable in any given portfolio to take some high risks, the GAO
declares, it is not sound for all investments to be
high-risk--particularly when the capability is as critical to the
conduct of military operations as the mission-warning capability is.
