Saturation ballistic missile at-tacks against littoral
forces, ports, airfields, storage facilities, and staging
areas could make it extremely costly to project US
forces into a disputed theater, much less carry out
operations to defeat a well-armed aggressor. Simply
the threat of such enemy missile attacks might deter
the US and coalition partners from responding to aggression
in the first instance."
Gen. Ronald R. Fogleman, the Air Force Chief of Staff,
conjured up this bleak scenario in a recent statement
about the threat posed by Third World missiles and
the Air Force's determination to help counter it.
USAF leaders say it is the threat elaborated on by
General Fogleman that has pushed the Air Force more
deeply than ever into the world of missile defense.
The Air Force's existing system of air- and spacebased
sensors, communications channels, and intelligence
systems has improved dramatically since the Persian
Gulf War, when US forces put together an ad hoc system
to feed launch detection data picked up by Defense
Support Program (DSP) satellites through USAF's communications
channels to the Army's Patriot antimissile batteries.
USAF today is assuming a key role in plans for active
defense of US and allied forces against missile attack.
The Air Force, with its fleet of attack fighters, surveillance
systems, and communications, would, in most cases,
be a prime instrument for preemption of enemy missiles
on the ground. Moreover, it is developing a laser weapon
that it believes would be able to shoot down missiles
shortly after they were launched. [See
"The
Airborne Laser," January 1996, p. 54.]
USAF also is cast for a major support role, providing
the means for the complex task of commanding and controlling
US forces engaged in finding missiles, monitoring their
status, detecting their launch, and shooting them down.
The Air Force has the job of building the architecture
for missile defense command and control, and USAF's
authority over the joint-force command-and-control
function has been enshrined in joint doctrine. A Defense
Department memorandum of understanding to this effect
was signed July 8, 1994, designating the Air Force
as the lead agency in this area.
Last year, the Air Force established a Theater Air
Defense Office within the Air Staff, directed until
recently by Maj. Gen. W. Thomas West. Setting up a
definable entity with responsibility for all aspects
of theater air defense, including missile defense,
was a major step for the Air Force. The office's functions
were recently placed under the deputy chief of staff
for Plans and Operations.
Theater Missile Defense (TMD) has not traditionally
been an Air Force priority, but the service's substantial
budget commitment to its programs appears solid.
Attack Operations
For their part, the Army and Navy are developing six
terminal- and wide-area TMD systems. The Army entries
are the standard Patriot system, the Patriot Advanced
Capability-3 system, the Medium Extended Air Defense
System (also known as Corps SAM), and the Theater High-Altitude
Area Defense system. The Navy has a pair of seabased
systems known as Lower Tier and Upper Tier, the latter
a wide-area defense viewed as the most promising.
The Air Force expresses no institutional interest
in embracing such "catcher's mitt" systems--designed
to intercept speeding warheads late in their flight
as they are about to strike the target.
"When you look at terminal defense, the Air Force
really doesn't have a dog in that fight," said
General Fogleman. "That's a combination of Army
and Navy systems. . . . We think the major contribution
we're making is in the areas of battle management,
attack operations, and boost-phase intercept" (BPI)--areas
focused on the early stages of an enemy's missile attack.
"What we would like to do is get those things
[ballistic missiles] with attack operations before
they ever have a chance to launch," said Col.
William R. Carter, the Air Force official heading the
command-and-control combat integration requirements
division. "That's really the first line."
To that end, the service has been developing new means
of detection and ways to get information instantly
to the pilot flying Scud-hunting missions. However,
the Air Force concedes that direct attack will always
be hampered by skillful use of camouflage, mobility,
and concealment.
Colonel Carter acknowledged this, adding, "If
[the missiles] do launch, we would really like to get
them in a boost phase [just after launch, before the
rocket engines burn out], where the bad stuff falls
all over the bad guys. And maybe that's a disincentive,
so if they [prepare to] light the wick on that thing
the next time, they'll think twice about it falling
back on them."
The deterrent would be especially strong if the missiles
were armed with nuclear, biological, or chemical warheads.
USAF officials warn that attack and BPI operations
should not be regarded as a complete missile defense.
A complete system would require other layers, such
as the Army and Navy area and point-terminal defenses.
The Second Line
The Air Force has adopted BPI as the second line of
defense after attack operations. The BPI mission initially
went on the drawing board as a high-speed interceptor
missile that would be fired from a fighter aircraft.
The Clinton Administration asked for a relatively
small amount--$49 million in the current fiscal year--for
kinetic-kill missile research, out of a missile defense
budget request of $2 billion. The future of this system
is uncertain.
The most important Air Force BPI TMD system being
developed is the airborne laser (ABL). "As we
look at boost-phase intercept, it's no secret that
we're looking at the ABL as really the weapon that
will probably provide us with the most capability in
that area, so we're engaged there," General Fogleman
said.
The service is working hard to build a chemical-fired
laser gun fitted aboard a Boeing wide-body jet, and
tests so far have been encouraging.
"We're going to intercept [the missiles] when
[they are] in powered flight," said Col. Richard
Tebay, program director for the ABL. "If we can
get them in the boost phase, it's a way of reducing
the number of targets subsequent tiers have to deal
with."
The ABL is in the concept design phase. Competing
for the program are two industry teams--one led by
Rockwell International (teamed with Hughes and E-Systems)
and a second led by Boeing (teamed with Lockheed Martin
and TRW).
Once the design has been worked out, a demonstrator
phase will begin, probably in 1997. Plans call for
this phase to culminate in 2002 with the shootdown
of an actual theater ballistic missile, said Colonel
Tebay, who added, "We've come a tremendous way" with
the program.
The system will have its own infrared sensors capable
of picking up a missile launch hundreds of miles away.
The ABL also has its own tracking, detection, and acquisition
sensor, with a 360° sweep and can use external
target "cuing" from spacebased sensors.
The ABL is strictly a theater weapon that would operate
over friendly territory and yet be able to fire at
threatening missiles as they rise through enemy airspace--all
without violating borders.
Col. Patrick Garvey, an Air Combat Command officer
serving as an advisor to ABL officials, sees great
value in the system, as in the protection of forces
deployed abroad for military operations. "We are
committed to the airborne laser development," he
said.
Colonel Tebay noted that the ABL would be able to
deploy rapidly from the United States and go into action
almost right away. "You don't deploy it and then
spend a month getting it ready to go," he said. "It
arrives ready to do its mission."
Once the first demonstrator is fielded in 2002, the
Air Force will have the capability to position aircraft
outside enemy territory and set up on-orbit combat
air patrols that can protect arriving friendly troops.
Battle Management
General Fogleman believes USAF will play the key role
in battle management and command and control, adapting
and upgrading systems once focused on the Soviet threat
to support forces threatened by short- and medium-range
missiles.
He asserted that the Air Force is committed to its
role as the lead missile defense command-and-control
agency. The General pledged that the Air Force "will
integrate existing architectures and develop future
ones that provide warfighting CINCs a flexible and
seamless command-and-control system."
Colonel Carter noted that the problem has always been
the high speed needed to attack enemy missiles and
the lack of time available for making decisions. "We
haven't had the command and control to use the destructive
capability or the intrusion capability or the attack
capability to do much about it," he said.
"In the Gulf War, we were not very effective" against
Iraqi Scuds, he added. "We just didn't have the
intelligence fusion, the rapid decision-cycle capability,
[or] the target-recognition tracking capabilities to
get those things, on the ground or in the air."
Of all the elements of battle management/command,
control, communications, computers, and intelligence
(BM/C4I), control over forces
is most important, in the view of Colonel Carter. "If
you don't have control, you can be the best commander
in the world and it does not matter," he said.
Communications is the medium for working; computing
is merely one of the tools. Intelligence was brought
into the function because of the surveillance and reconnaissance
mission.
"Information on the battlespace is what I need,
and I don't care if it comes off X sensor or Y platform," Colonel
Carter said, adding that command-and-control functions
must make sense of the vast amounts of data that systems
provide and then be able to sift through and use the
data in making battlefield decisions.
A recent joint military exercise in the Atlantic illustrated
the problems of not having strong central control over
the battlespace. During a simulation, a Patriot antimissile
battery acted unilaterally and unintentionally shot
down a Navy F-14. During a second simulated engagement,
a Patriot shot down an incoming missile armed with
a mass destruction warhead at the worst possible time,
spreading deadly debris over a large civilian population
area.
"This is what happens when you don't have integrated
command and control," one Pentagon official remarked.
The Combat Integration Center, another command-and-control
element, is being developed by the Air Force, along
with the Ballistic Missile Defense Organization and
the Marine Corps. The CIC is a version of the Command
Report Center used in tactical air defense efforts.
It will be improved and adapted for missile defense.
The goal is to decentralize attack operations against
mobile theater ballistic missiles. The center takes
sensor data from satellites and joint radar and flashes
the information throughout a battle theater.
A prototype CIC used during a recent exercise helped
to connect sensors with shooters effectively within
two minutes.
In addition, the Air Force has developed a new system
that provides intelligence fusion to the air commander
in regional conflicts. The Joint Force Air Component
Commander Situational Awareness System (JSAS) was also
used successfully during Roving Sands, a Joint Chiefs
of Staff exercise held each year in Texas and New Mexico.
The system puts tactical intelligence imagery into
what General Fogleman said is an easily viewed presentation
on a laptop computer.
"Marine Corps and Air Force users lauded its
contribution to the conduct of the air battle [during
Roving Sands], particularly missile defense operations," said
the Chief of Staff.
As part of the BM/C4I function,
the Air Force also is upgrading its theater air control
systems to adapt them to deliver the type of command
and control needed for missile defense operations.
In April 1995, initial operational capability was
declared for the Attack and Launch Early Reporting
to Theater system, an array of satellite ground stations
that collect and pass on information from spacebased
sensors. ALERT will give the Air Force quicker warning
of missile launches detected from spacebased sensors
and will provide better cuing data to missile defenses
than is provided by the groundbased equipment that
is part of the weapons.
Space and Airborne Sensors
A crucial part of the Air Force role in missile defense
is the contribution of its sensors, and the centerpiece
of that effort is a new advanced satellite constellation
being built to replace the DSP satellites. Right now,
DSP is the mainstay for providing missile warning information
to strategic and theater commanders and their forces.
The new system being developed is a layered constellation
of satellites that goes by the generic name Spacebased
Infrared system. Lt. Col. Robert R. Fisher, an SBIR
system program official, said Operation Desert Storm
showed that the DSP missile launch warning systems
needed improvement, and, after several false starts,
the Air Force is moving ahead.
"DSP was built for strategic operations during
the Cold War," Colonel Fisher noted. "Its
secondary mission was to support theater operations
and obviously [we] can only do so much improvement
with the Defense Support Program satellites."
DSP satellites were used successfully in the Gulf
War to help Patriot missile batteries target Iraqi
Scud missiles, but the data transfer rate from Cheyenne
Mountain AS, Colo., where US Space Command received
the satellite information, was slow. A system had to
be cobbled together during the war to link the data
to the Patriot batteries.
The new system will be composed of three levels of
spacecraft. One will be a group of low-Earth-orbit
space and missile tracking system satellites, formerly
known as Brilliant Eyes. Another level will comprise
two satellites that orbit Earth's poles. The last will
be composed of four geosynchronous-orbit satellites
that will provide wide coverage of Earth. The first
elliptical and geosynchronous orbiting satellites will
be launched in 2002; the lower satellites will be launched
starting in 2006.
The new system will have improved data-processing
hardware and software, with improved communications
systems.
Colonel Fisher said the SBIR system will provide greatly
improved warning of missile launches around the world
and better data for active defenses, such as attack
operations against missile sites on the ground, as
well as for various phases of interception. It will
provide more information for situational awareness.
"This system will report ballistic missile launches
directly to affected theater forces and provide critical
midcourse tracking and discrimination data for terminal
defenses," General Fogleman said. "This cuing
by the SBIR system will, in effect, extend an interceptor's
range and increase its effectiveness against ballistic
missile warheads."
