EXECUTIVE SUMMARY
Title: The need for a Greater Expeditionary Capability in the
United States Air Force
Author: Major Richard A. Fryer Jr., USAF
Thesis: The changing world scene implies the USAF must be an
expeditionary force to be able to project significant power in
all contingencies.
Background: The Chief of Staff of the Air Forces sees a major
challenge for the USAF as the need to move toward a more
expeditionary Air Force. An expeditionary capability requires
the right organizations, logistics network, and, perhaps most
importantly in the near term, hardware. World events bear this
out as the U.S. either voluntarily or involuntarily falls back
from its overseas basing network; a network the USAF is heavily
dependent upon to project significant combat overseas. But, what
constitutes an expeditionary air force is not clear. The author
presents his view of the "ideal" expeditionary capabilities of an
air force which include low reliance on developed basing
structure, various necessary support organizations, and the
logistically infrastructure which best supports expeditionary
operations. When this "ideal" is compared to present USAF
capabilities the most glaring limitation to Air Force expeditionary
operations would appear to be the operational limitations of its
primary fighter aircraft. More specifically, the.lack of
capability of present USAF aircraft to operate from the austere
bases. Follow-on aircraft such as the ATF, and perhaps the
A-X, appear to be capable of overcoming this limitation. In the
meantime, the USAF should consider means of overcoming these
limitations.
Recommendation: The USAF should study means of overcoming the
limitations of its present fighter aircraft to operate from
austere airfields.

THE NEED FOR A GREATER EXPEDITIONARY CAPABILITY
IN THE UNITED STATES AIR FORCE

Major Richard A. Fryer Jr.
INTRODUCTION
The world political scene is in transition; this is not
new news. Nor is it new that no one can predict the future
world political steady-state with absolute certainty
(assuming such a "steady-state world" lies in store for us).
In this paper, I will not discuss possible outcomes of this
transition, but instead will discuss a major implication of
this "new world order" for the United States Air Force (USAF).
This implication is what General Merrill A. McPeak,
Chief of Staff of the United States Air Force, sees as one of
two larger challenges facing the Air Force. One involves a
blurring of the distinction between tactical and strategic
"air forces" resulting in the need for what he calls
"composite structures." The other challenge is. the need to
move toward a more expeditionary Air Force, one "that moves
quickly from a CONUS [continental United States] location to
a forward position and is ready to fight immediately when it
gets there."(7:4) The former challenge is presently being
addressed in a major, USAF-wide re-organization. However, it
is the latter, more difficult challenge the USAF must
overcome if it is to remain the premiere air force of the
United States and, consequently, the world. An expeditionary
capability requires the right organizations, logistics net-
work, and, most importantly in the near term, aircraft.
It is this latter challenge to which I turn my attention
in this paper. The intent of this paper is to examine in
broad terms the capabilities the USAF needs to be expedition-
ary. Specifically, I intend to discuss the changing global
political scene and how it implies the need for a more
expeditionary Air Force. Then, I will present the capabil-
ities of an "ideal" expeditionary Air Force and determine
which expeditionary capabilities the USAF presently
possesses. Finally, I will discuss what I see as the critical
limiting factor the Air Force must overcome to fulfill
General McPeak's challenge, the limits of our aircraft.
WORLD POLITICAL SCENE IS CHANGING
The world political scene is in transition. The
Director of Strategic Plans and Policy for the Joint Chiefs
of Staff, Lieutenant General George Butler, put it this way,
[T]he global arena in which these aims [fundamental U.S.
security objectives] find their context is undergoing
such a profound transformation that virtually all of the
givens that have shaped our national strategy for four
decades have been called into question.(3:1)
However, this is not to say that this new "context" means an
end to threats to U.S. security. "These changes do not
promise a tranquil world nor an end to threats to American
interests around the globe."(11:2) Yet, the apparent death
of the Soviet Union with the resultant lessening of tensions
for a major conventional/nuclear conflict fought on the
European continent has brought questions about national
defense postures in European countries as well as in the
United States. Cut-backs are planned in most NATO (North
Atlantic Treaty Organization) countries and are already
underway in the United States. Politicians, both at home and
in Europe, are questioning the need for a continued U.S.
presence overseas. (9)
The same questioning of U.S. presence is on-going in the
Pacific despite the continued existence of major regional
threats such as North Korea. In one area, the pull-out has
begun as we depart from major, long-held installations in the
Phillipines. In another area, the Republic of Korea (ROK),
the U.S. has unilaterally removed its nuclear weapons.
Moreover, slight reductions of U.S. forces in the ROK have
been proposed. However, these reductions could conceivably
mirror that of the Phillipines should further reconciliation
occur between North" and South Korea. Additionally, with
increased trade tension between the United States and Japan,
it is not inconceivable that Japan could limit our presence
or operations at any point in the future in retaliation for
trade disagreements.
IMPACT OF WORLD CHANGES ON THE USAF
The overarching effect of these world events upon the
USAF is the potential loss of overseas bases critically
needed to carry out its missions. An inescapable fact of
airpower is that it must to come back to the surface for
refueling, maintenance, rearming, crew-changing, and
redirecting. Effectively, an air force is tethered to the
airbases from which it is launched, whether they be land-
based or sea-based.
The USAF is especially vulnerable in this regards due to
its need for in-theater bases with long, well-paved surfaces
for its fighter aircraft. As the Secretary of the Air Force
put it, "typically, land-based fighter forces require forward
basing to sustain power projection options."(10:9) The Air
Force does the nation a disservice if it cannot "get" to a
war due to an inability to use existing, austere in-theater
bases. To be an effective force capable of what the
Secretary of the Air Force calls "global reach/global power,"
the USAF must have this capability.
Additionally, the USAF needs expeditionary capabilities
to free itself from being a "hostage" of overseas basing
agreements. I refer to the ability of other nations to
deny or constrain our operations overseas. A fairly recent
example of this dependency was demonstrated during Operation
El Dorado Canyon (the 1986 Libyan Air Raid) when striking F-
111s were required to fly a long, indirect route from the
United Kingdom to Libya because Spain denied basing and
France denied overflight.
An answer to this dilemma, put forth by some, would
seemingly be that the United States will not fight further
regional conflicts without partners (i.e. coalition warfare
such as we saw in Desert Storm).(8) Clearly, under such a
philosophy, the U.S. would always expect to have access to
regional basing rights in any theater of operations where we
would fight. In other words, "when the interests of our
allies are threatened, basing will normally be made avail-
able."(10:9) Indeed, some prominent leaders in America
believe the U.S. will not go to war again without partners.
Yet, there are potentialities unaccounted for in the
answer presented above. Specifically, it ignores circum-
stances where only our vital interests are threatened and
where, consequently, others would have no national self-
interest in assisting us. Additionally, it ignores circum-
stances where others may have a self-interest, or where
others are threatened as "well, but they choose to deny us
bases and access for reasons of fear, for cultural reasons,
or for some other reason valid to that government.
In the National Security Strategy of the the United
States, President Bush delineates the nation's strategy for
regional conflicts as one that always seeks allied support,
while still retaining a credible U.S. capability for global
reach and power projection (hence, the ability to "go it
alone" if necessary).(2) Clearly, the armed forces of the
U.S., including the USAF, must be prepared to respond to any
eventuality. As stated in Joint Pub 1, Joint Warfare of the
US Armed Forces,
The strategic context confronting the United States is
unique, and our friends, allies, and interests are
worldwide. Accordingly, the arena of our potential
operations is the entire planet.(6:2)
The U.S. must be prepared to go it alone, anywhere on
the globe to defend our vital interests. For the USAF, this
means being able to project airpower beyond our shrinking
overseas basing ring. To do this, the USAF must have the
capability for expeditionary operations.
CAPABILITIES OF AN IDEAL EXPEDITIONARY AIR FORCE
At this point, I will examine the operations, and
necessary capabilities, of an ideal expeditionary Air Force.
To do this, I will present what I believe to be the worst
case scenario for employment of the Air Force: a conflict in
a remote part of the world without in-theater friends or
allies (and thus without basing). Then, I will present what
1 believe are the capabilities the USAF requires to operate
ideally in such unfavorable circumstances. Finally, I will
review these expeditionary capabilities and their possible
effect in other types of conflicts including a coalition air
effort similar to that of Desert Storm.
The scenario I present involves the need to conduct
combat in an area remote from the United States and its
overseas bases. To add to this, the scenario will assume no
regional country will allow our forces to operate from or
through their territory. In sum, these are the worst case
conditions for a conventional war from the USAF viewpoint.
Admittedly, it is possible to apply some USAF combat airpower
independently in the form of unescorted bomber strikes
launched from the U.S. or U.S. territories. However, over-
whelming combat airpower can not be brought to bear until
aircraft can be brought into the theater and operate out of
seized territory.
Clearly, the first step to Air Force operations in such
a scenario would involve the seizing of territory containing
airfields by ground troops. Then, support forces would be
introduced to secure the base (security police), repair and
expand critical airfield surfaces to the minimum necessary
for preliminary operations (engineers), and establish the
initial logistics infrastructure (logisticians). Next,
fighter forces would be introduced into thee seized territory
with an initially constrained tempo of operations due to
logistics and support limitations. Delivery and build-up of
logistics and the development of the infrastructure necessary
for sustained high-level operations would be an on-going
priority operation, heavily dependent upon available sea- and
air-lift reception facilities (ports and airfields). Initial
flight operations would likely center on combat air patrol
(CAP) and limited offensive counter-air missions as these
require the least mass of munitions (although fuel require-
ments are still sizable). As the logistical infrastructure
grows, operations could shift to a full-scale air superiority
campaign to include CAP and offensive counter-air operations
against enemy airfields, command and control, air defenses,
and communications. Once most forces were in place, full
logistics support available, and the air superiority campaign
essentially won; air operations could shift priority of
effort to "strategic" targets, air interdiction, battlefield
isolation, and/or close air support at the choice of the
joint task force (JTF) commander. Clearly, all this hinges
on that first step, seizing ground somewhere in theater for
the introduction of Air Force airpower.
But, to make this task practical, there must be air-
field(s) suitable for the introduction of the Air Force.
That is to say the Air Force hardware must be expeditionary
itself to a certain degree or there would be no place
available in-theater for ground forces to secure capable of
sustaining USAF air operations. For instance, if all USAF
aircraft could only operate from 7,000 foot runways and only
3,000 foot runways existed in theater, the USAF would be
unable to contribute its airpower to the conflict until
adequate airfields were constructed (which takes considerable
time and resources). However, the problem would still not be
solved even if there were one or two airfields with the
necessary facilities. An opponent would know our needs and
would, accordingly, concentrate his defensive and denial
efforts on those particular airfields. Clearly, the more
expeditionary the capabilities of the USAF, the greater
flexibility ground forces have in securing adequate
facilities. Moreover, the chance of success will be greater
due to the enemy's greatly increased defensive problem.
I believe the "ideal" expeditionary Air Force is
one that could deploy from the United States, fly to any
point on the globe and conduct combat operations out of a
small pocket of captured enemy territory. Obviously, the
first capability needed is aerial refueling; both long-range
aircraft with the capability to refuel and others with the
capability to be refueled. Next, the expeditionary Air Force
operating out of hostile territory must be flexible in its
basing needs to allow for operations off of any available,
long, straight strip of pavement (to interject a note of
practicality, say longer than 2,000 feet). Thus, either the
Air Force's aircraft must be capable of operating unassisted
off such a surface or systems must be provided to assist them
in doing so (such as barriers and catapults). Additionally,
the expeditionary Air Force needs its own organic maintenance
and support organizations capable of supporting it in any
environment and requiring the minimum of people, equipment,
and supplies. Amongst the support organizations must be
security, services, logistics, and engineering. The latter
must be capable of infrastructure development to include
runway and parking repair and expansion as well as facility
and utility repair and expansion. In that line, the expedi-
tionary Air Force should require minimal facilities beyond
pavements and packaged airbase kits. These kits containing
personnel shelters, generators, field kitchens, and such
equipment could be transported with other bulky items such as
equipment, spares, fuel, and munitions. However, adequate
airlift would unlikely be available to bring in anything but
the most urgently needed bulk items. Thus, the ideal
expeditionary Air Force would use pre-packed maritime pre-
positioning to save time transporting bulk requirements.
Having identified what I see as ideal capabilities of
the expeditionary Air Force, a review of these capabilities
as applied in other types of conflicts indicates no incompat-
ibility. In a coalition theater war such as Desert Storm,
all the capabilities above would only serve to enhance the
Air Force's effectiveness. For instance, systems that allow
for operations off of austere airfields would allow for
greater basing flexibility and enhance force protection by
allowing greater dispersion. Additionally, maritime pre-
positioning enhances rapid build-up of bulk logistics and
equipment, thereby, enabling sustained, high-tempo combat
operations earlier. These capabilities are-not limited to
enhancing just maid- and high-intensity conflict.
Low-intensity conflict can occur in remote locations
with no secure rear area. With adequate security forces and
the ability to operate out of austere facilities, the
flexibility is available to choose the most secure option (if
that is the important factor) from a wider variety of
options. Moreover, the flexibility inherent in expeditionary
engineering and medical forces can provide added "forces" to
fight a low-intensity conflict through civic action.
EXPEDITIONARY CHARACTERISTICS OF THE USAF POSSESSES TODAY
The USAF has made great strides preparing for high tempo
combat, improving its supportability, and, to a certain
extent, improving its expeditionary capabilities. An example
of the first is provided by the close integration of assets
we have achieved to fight and survive in today's more
sophisticated combat environment. Airborne warning and con-
trol, fighter escort, electronic warfare, and reconnaissance
are routinely orchestrated and synchronized in conjunction
with air strikes.
Moreover, the USAF has championed airlift and aerial
refueling to provide all U.S. forces with the mobility to
reach any area on the globe.(5) The Air Force has not
ignored the need to update its strategic lift as exemplified
by its commitment of resources and focus to the replacement
for the C-141. This aircraft, the C-17, will incorporate
expeditionary features such as "survivability, ability to
operate from short, unimproved airfields, agility and
enhanced maneuverability in the air and on the ground, and
the ability to employ various methods of airdrop."(5:2l-22)
Additionally, the USAF has spearheaded the development
and fielding of better munitions; better in terms of accur-
acy, lethality, and range. Aircraft range, endurance, and
all-weather operating abilities have also been extended.
Maintenance has been greatly improved resulting in more
aircraft in service, requiring a smaller logistics train, and
(important for support and sustainment considerations) less
maintenance personnel.(12) For example, "the F-16C
requires, in terms of dollar value, only one sixth the spares
needed to support the F-111, and less than half that of the
F-15C. "(12:2)
The Air Force has also learned lessons from past
conflicts and recognized some of its vulnerabilities and
shortcoming. In response, it has developed, structured, and
improved organizations for airbase security (using relatively
heavily-armed, air-transportable security police squadrons),
combat "services" support (specifically food, laundry,
billeting, and mortuary support provided by mobile services
teams), and engineering support.
This last organization factors heavily upon the expedi-
tionary capabilities of the USAF. The Air Force, by Depart-
ment of Defense directive, is required to rely upon U.S. Army
support for airbase construction. However, in recognition of
the failure to receive that support in the Korean and Vietnam
wars, the USAF developed and still maintain its own organic
engineering capability. These engineers are structured to be
able to repair and develop existing in-theater bases. Two
types of engineering organizations exist to provide the
necessary expedient base development capability.
The first, Prime BEEF (Primary Base Emergency
Engineering Force), is resident in the base civil engineering
squadron at every active Air Force base. Prime BEEF teams,
consisting of trained military engineers, are linked to the
wing's flying squadrons and, ideally, deploy in advance of
the aircraft to prepare receiving base facilities for flying
operations. However, they rely heavily on either pre-
positioned kits, host nation support, or equipment and
supplies flown or shipped to the base.
The other, RED HORSE (Rapid Engineer Deployable Heavy
Operations and Repair Squadron, Engineer), are Major Command-
owned squadrons designed to accomplish major repair and
development of airbases. Similar to a small Army construc-
tion battalion ore a Navy "SeaBee" battalion, they possess a
large amount of heavy construction equipment that requires
sealift or a great many airlift sorties to transport. While
a great capability, USAF engineers require a friendly port or
significant airfield in-theater in order to receive their
necessary equipment and supplies.
Additionally, the USAF has recognized to some degree its
reliance of bases and has developed and pre-positioned
airbase kits at strategic points around the globe. One type
of kit, Harvest Bare, is designed to provide all the
facilities and equipment needed for a 4,000 man airbase.
Another kit, Harvest Eagle, provides the same for a 1,000 man
force, which could operate at a co-located operating base or
augment a main operating base. However, use of both kits is
predicated upon an existing runway and parking area and water
source suitable for combat operations.(4) Moreover, use of
these kits requires a great deal of transportation.
Finally, the USAF has used maritime pre-positioning to
store necessary bulk supplies such as munitions. These
assets were tapped during Desert Storm to supply- deploying
combat forces. Reconfiguration, and possibly expansion, of
maritime pre-positioned supplies, as a result of Desert Storm
lessons, is likely.
THE CRITICAL LIMITATION TO AN EXPEDITIONARY USAF
As presented above, the USAF has, or is, acquiring many
of the capabilities necessary to be an expeditionary Air
Force. However, the above discussion should have made it
clear the greatest single factor Influencing further develop-
ment of an expeditionary capability is the hardware
(specifically, the fighter aircraft) the USAF owns.
The great majority of the Air Force's present combat
aircraft are the multiple-purpose fighter, F-16 (over 1,000
as of 30 September 1989), and the air superiority and ground
attack fighter, F-15 (over 700). (1:52) These are very
capable aircraft with good range and a good maintenance
history, but with poor austere-field operating capability.
One aspect of this manifests itself as minimum runway length
(MRL); the design length and clearance pilots require to
"recover safely from emergencies."(4:4-2) For the F-15 and
F-16, this design distance is 6,000 feet at forward operating
locations and 8,000 feet in rear areas. This is high
compared to the MRL for a more austere capable aircraft such
as the C-130 (MRL of 3,500 feet for forward locations and
6,000 in rear areas).(4:4-2)
Another aspect of austere field capability is the rough
field operability of an aircraft. This generally measured by
the capabilities of an aircraft's landing gear and airframe
to absorb the shock of "bumps" in airfield pavements
(referred to as sink rate of landing gear struts). Both the
F-15 and F-16 are poor in this regards compared to other
"tougher" aircraft such as the A-7 or A-10. Additionally,
the F-16, because of its low engine inlet, requires pavements
completely free of debris to forestall foreign object damage
(FOD) to the engine. Thus, spalling airfield pavements
(where runway surfaces are breaking up), found in many third
world countries, are unacceptable for F-16 operations without
repair.
However, aircraft presently under development for the
USAF will have far better austere capabilities. While exact
figures are classified, minimum runway length and rough field
operability for the Advanced Tactical Fighter (ATF) will be
significantly improved over present fighters. Additionally,
the ATF will self-contain much of what is presently needed
for ground support equipment and provide easy access for
maintenance crews.
Also, the Air Force's next generation ground attack
aircraft may well be the A-X, the Navy's attack aircraft
under consideration. By its very nature as a carrier
aircraft subject to great stress from catapults for take-off
and barriers for landing, the A-X should be capable of
operating under rough conditions in austere environments.
Unfortunately, we will be into the next century before both
aircraft become fully operational.
However, given the aircraft the USAF presently owns and
operates and the likely period before they are replaced with
aircraft more favorable to expeditionary operations, the Air
Force must come up with solutions to cover the difficulties
I have outlined herein. An answer to one aspect of this
problem, that of landing aircraft on austere bases, may
already be found in modifications to the barrier systems the
USAF uses to catch aircraft with brake problems or other
emergencies. While these are not presently designed for
continuous engagements, modifications may allow them this
capability. Perhaps a solution to the take-off portion of
the problem may be expeditionary catapults or cheap, dispos-
able rockets designed to provide the extra thrust necessary
to take-off in shorter distances.
CONCLUSION
The Air Force has many of the capabilities necessary to
be an expeditionary air force. However, one critical factor
limits the ability of the Air Force to deploy in strength,
fly, and then fight in any region on the globe. This is the
inability of the majority of its fighters to operate from
austere airfields. A long-term solution appears already
available with the next generation of fighter aircraft under
dvelopment. But, in order for the Air Force to have an
expeditionary capability soner as senior leadership feels is
necessary, a near-term solution to this problem must be
found.
