Civilian contract air refueling: the ability to project and sustain military power over vast distances is a basic requirement of deterrence. (Innovative or Insane?).


Simply put, America's National Security Strategy, built on the imperative of world-wide engagement, demands nothing less than the best global transportation system the world has ever known, one capable of projecting U. S. strength and resolve--anywhere, anytime.

General Charles T. Robertson, Jr (1)

The ability to project and sustain military power over vast distances is a basic requirement of deterrence-the first line of our national security. (2) General Charles T. Robertson, Jr, commander of US Transportation Command (USTRANSCOM USTRANSCOM United States Transportation Command ), stressed this point when he noted the importance of rapid global mobility to the nation's ability to project and sustain military power.

As a force multiplier, it bridges the gap between the continental United States United States, officially United States of America, republic (2005 est. pop. 295,734,000), 3,539,227 sq mi (9,166,598 sq km), North America. The United States is the world's third largest country in population and the fourth largest country in area.  (CONUS) and various theaters of operation, accelerating the deployment cycle and reducing dependency on forward staging bases and host-nation support.

While deterrence is the first line of national security, the ability to fight and win, regardless of the level of conflict, is the bedrock of our national security. (4) Air refueling's second role, force enhancement, is critical to military activities in this regard. As a force enhancer, it extends the range, payload (1) Refers to the "actual data" in a packet or file minus all headers attached for transport and minus all descriptive meta-data.

These unique capabilities, force multiplication Force multiplication is a military tactic that is supposed to visually magnify a force, such as a division or an army, through means using decoy vehicles or use of terrain to deceivingly create a much larger force than it really is.  and force enhancement, make air refueling an indispensable military resource.

Despite their importance to national security, air-refueling assets have dwindled. A June 2000 General Accounting Office (GAO) report on military readiness concluded the Department of Defense (DoD) is 19 percent short of the air-refueling capability required to execute wartime plans. (5) Additionally, the Air Mobility Command's (AMC (Advanced Mezzanine Card) See AdvancedTCA. ) Air Mobility Strategic Plan 2000 identifies two deficiencies directly related to air-refueling capabilities. (6) The first is increased depot-maintenance cycle time for the aging KC-135 tanker fleet, and the second is the unknown service life of the KC-135 airframe. (7) AMC planners predict a need to begin retiring KC-135s in fiscal year(FY) 2013. Currently, there is no replacement tanker on the drawing board or in the budget.

These shortfalls have spawned the question: is it feasible and/or desirable for the Air Force to pursue a civilian contract air-refueling (CCAR CCAR Central Conference of American Rabbis

) capability?

Civilian contract air refueling is a unique concept that presents a near-term solution to the air-refueling shortfall. The Air Force could realize three advantages from pursuing a CCAR capability. First, it would fill the gap in projected deficiencies--now and in the future. Second, it would give receiver units greater opportunity to maintain currency and proficiency in air-refueling operations. Finally, it would enhance air-refueling flexibility and improve airpower air·pow·er or air power

Air-Refueling Doctrine

Air and space power employment is guided by the principles of war and tenets of airpower, implemented through core competencies. Airmen must understand these fundamental beliefs as they apply to air and space power.

Air Force Doctrine Document 1 (10)

Air refueling provides the capability to increase levels of mass, surprise, economy of force, and security and concentrates more assets for offensive or defensive operations. (11) The overall effect of this capability is to enhance and multiply airpower employment capabilities. For example, air refueling an attack aircraft en route to its target allows greater payloads, which enhances the ability to achieve mass and concentration of firepower fire·pow·er

 at any level in an adversary's battlespace. It also allows attacking aircraft to use indirect target approaches, terrain masking, and multiple axes of attack to create surprise. Air refueling other support aircraft increases time aloft and decreases the number of aircraft and aircrews needed to build an air bridge or provide 24-hour command and control capability, thus achieving economy of force. It also enhances maneuver by providing additional fuel to attacking aircraft, which generates a valuable maneuver advantage during air-to-air engagements, while putting the adve rsary at a distinct disadvantage. Air refueling mobility airlift aircraft presents another opportunity to achieve maneuver flexibility. Increasing the range and cargo load of these aircraft increases flexibility by allowing commanders to insert troops and cargo into theaters at decisive moments. Ultimately, this allows maximum use of resources and multiplies the force available, allowing greater persistence in engagements, operations, and campaigns. Finally, because air refueling increases range, airpower assets can be based beyond the effective range of enemy weapons. This increases security and frees up assets for offensive or defensive operations.

Air Force Core Competencies

Six elements comprise Air Force core competencies: rapid global mobility, precision engagement, global attack, air and space superiority The degree of dominance in space of one force over another that permits the conduct of operations by the former and its related land, sea, air, space, and special operations forces at a given time and place without prohibitive interference by the opposing force. See also space. , information superiority That degree of dominance in the information domain which permits the conduct of operations without effective opposition. See also information operations. , and agile combat support. Air-to-air refueling capabilities both enable and are enabled by these competencies as shown in Table 1.

Air Refueling in Action

Air refueling means we can get anywhere very quickly, take off anywhere, attack anywhere and return anywhere, without landing en route. No spot on the globe is more than 20 hours flying from combat aircraft stationed in the United States.

In June 1948, the Strategic Air Command stood up the first squadron of KB-29M Superfortress tankers and created a unique force capability for worldwide power projection--a completely new military capability.

While the first combat use of air refueling occurred during the Korean War Korean War, conflict between Communist and non-Communist forces in Korea from June 25, 1950, to July 27, 1953. At the end of World War II, Korea was divided at the 38th parallel into Soviet (North Korean) and U.S. (South Korean) zones of occupation. , Vietnam was the first major combat operation that clearly demonstrated the utility of air refueling. In just a little more than 9 years, KC-135s flew 194,687 sorties, conducted 813,878 inflight refuelings, transferred 8.9 billion pounds of fuel, and logged 911,364 flight hours. (15) In an article saluting air refueling's contribution to the prosecution of the Vietnam War Vietnam War, conflict in Southeast Asia, primarily fought in South Vietnam between government forces aided by the United States and guerrilla forces aided by North Vietnam. , John L. Frisbee wrote:

They made it possible for Guam-based B-52s to reach their targets and for fighters to range from one end of Vietnam to the other, greatly increasing the flexibility of tactical air operations. Fighter strikes in the northern route packages were totally dependent on the tankers. (16)

Tanker employment procedures matured throughout Vietnam and the Cold War, paving the way for the most intensive operational use of air refueling to date--the Gulf War. (18)

The term Western Asia is sometimes used in writings about the archeology and the late prehistory of the region, and in the United States subregion . Deployments covered 6,900 nautical miles, took 15 hours of flight time, and required 7 to 15 air refuelings.

In addition to refueling coalition attack aircraft, tankers refueled the entire array of airborne warning, reconnaissance, targeting, and command and control aircraft that provided 24-hour coverage throughout Operation Desert Shield/Desert Storm.

Post-Gulf War

Since the Gulf War, air-refueling support has been used extensively for a wide range of operations. In 1995, tankers flew 383 Operation Deliberate Force support sorties that made the North Atlantic Treaty Noun 1. North Atlantic Treaty - the treaty signed in 1949 by 12 countries that established NATO  Organization's 17-day air campaign possible. These air-refueling flights comprised nearly 11 percent of the total missions flown during Deliberate Force. (22) More recently, tankers flew 4,347 sorties, offloading 188,100,000 pounds of fuel to more than 17,750 receivers during Operation Allied Force. (23)

A State of Emergency

If there were no falsehoods in the world, there would be no doubt, if there were no doubt, there would be no inquiry; if no inquiry, no wisdom, no knowledge, no genius.

--Walter Savage Landor (24)

Air-refueling capability has dwindled despite its proven importance to national security. The GAO concluded the DoD is 19 percent short of the air-refueling capability required to execute wartime plans. (25) As air-refueling shortfalls approach a state of emergency, visionaries are focused on a long-term solution: the next generation tanker, dubbed KC-X, which is scheduled to enter the inventory in 2013. However, the shortfall exists today and needs to be addressed with a near-term solution.

Analyzing the-Air Refueling Emergency

The Defense Department would need a one-third increase in budget simply to maintain the forces and capability it already has.

--Secretary of the Air Force F. Whitten Peters (26)

Four factors complicate AMC's long-term solution: force structure determination, one-for-one KC-135 replacement, time line for KC-X delivery, and unknown KC-135 service life, all of which open the door for a unique near-term solution-civilian contract air refueling.

Quantifying Air-Refueling Capability

Current air-refueling capability is defined by two measures of effectiveness Tools used to measure results achieved in the overall mission and execution of assigned tasks. Measures of effectiveness are a prerequisite to the performance of combat assessment. Also called MOEs. See also combat assessment; mission. : the number of tankers required and amount of fuel offload To remove work from one computer and do it on another. See cooperative processing.  required. Historically, boom-intensive operations make the number of tankers available the most critical measure of effectiveness during the employment or strike phase of a campaign. Figure 1 shows AMC's current and forecasted air-refueling capability as a function of aircraft availability.

As Figure 1 depicts, there are 547 KC-135s and 59 KC-l0s in the Air Force inventory. In 2013, AMC expects to begin replacing KG-135s with KG-Xs on a one-for-one basis, keeping the overall number of tankers at approximately 600.

During the deployment phase of operations, fuel available for offload is the critical measure of effectiveness because CONUS-based fighting forces require large fuel onloads to fly nonstop to distant theaters of operation. Figure 2 shows AMC's current and forecast air-refueling capability as a function of fuel offload available.

As Figure 2 depicts, the current offload capacity is 120 million pounds of fuel per day. Further, it was assumed that offload capability will increase in 2013 when KC-Xs replace KG-135s on a one-for-one basis.

Evaluating Current and Future Air-Refueling Capability

The tanker fleet must be able to support the requirements for both fuel offload and aircraft availability. According to according to

 a June 2000 GAO report on military readiness, the KC-135 fleet falls below the required mission capability (MICAP MICAP mission capable/mission capability (US DoD)
MICAP Mission Impaired Capability Awaiting Parts
MICAP Mission Impaired Cause Awaiting Parts
MICAP Mission Incomplete, Awaiting Parts
) rates for ensuring execution of wartime plans. In fact, the GAO's findings state KC-135s maintained a 67-percent MICAP rate for execution of wartime plans as opposed to the 85-percent MICAP requirement. While this rate is significantly lower than the requirement, AMC officials claim they could implement management practices to improve mission capability. They cited deferring depot maintenance That maintenance performed on materiel requiring major overhaul or a complete rebuild of parts, assemblies, subassemblies, and end-items, including the manufacture of parts, modifications, testing, and reclamation as required. , accelerating aircraft through their final days of depot maintenance, and flying some aircraft with missing or broken parts, which would not affect flight safety but would normally make them not mission capable (MC), as practices that could improve MICAP rates. While these actions would improve the MICAP rates, the length of time they could be sustained and the extent to which they would co unter the nearly 20-percent shortfall are not quantified by AMC officials. (29)

Table 2 and Figure 3 show the Kc-135 MC rate of 67 percent, which, when coupled with the KC-l0's 88-percent MC rate, still leaves AMC 84 aircraft short of wartime plan requirements.

The low MC rates for KC-135s are attributed to two factors: increased depot-level maintenance cycle times and availability of spare parts Spare parts, also referred to as Service Parts is a term used to indicate extra parts available and in proximity to the mechanical item, such as a automobile, boat, engine, for which they might be used.

Spare parts are also called “spares.
. Since 1991, depot-level maintenance cycle times have doubled. Secretary Peters described the dilemma to Washington reporters: "... 40% of the 40-year old KC-135R tanker fleet is down for repairs at any given time... it takes a year to get a KC-135 through depot maintenance because of all the age-related problems discovered during the periodic overhauls." (32) Shortage of spare parts has plagued KC-135 operations for nearly a decade. General Michael Ryan There are many notable people with the name Michael Ryan:

Force Structure

* KC-10. The newest aircraft in the air-refueling fleet is the KC-10, with an average age of 13 years. The 59 KC-l0s comprise only 10 percent of the Air Force tanker fleet but, because of their large offload capability, account for 33 percent of the total available offload capability. In addition to the KC-l0's air-refueling role, it also comprises 12 percent of the total military organic airlift capability The total capacity expressed in terms of number of passengers and/or weight/cubic displacement of cargo that can be carried at any one time to a given destination by available airlift. See also airlift requirement; allowable load; payload. . The crew ratio for the KC-10 is 2.0 for active duty units and 1.5 for associate reserve units. There are no plans to replace the KC-l0 through FY25.

* KC-135. With an average age of 41 years, the KC-135 is one of the oldest aircraft in the Air Force inventory. The 547 KC-135s make up 90 percent of the Air Force's tanker fleet but account for only 67 percent of the available fuel offload capability. The crew ratio for CONUS-based, active duty KC-l35 units is 1.36. For active duty, Air National Guard, and Air Force Reserve Command forces outside the CONUS, the crew ratio is 1.27. AMC is planning to begin KC-135 replacement in FY13. The current AMC force structure plan is presented in Figure 4.

Force Structure Determination

Despite the value of tankers to airpower projection and engagement, a rather indirect approach is used to determine the tanker force structure. AMC's Air Mobility Strategic Plan 2000 highlights the shortfalls of this approach:

The tanker requirements study justified the current tanker force structure and identified significant shortfalls in both aircraft and aircrews. This study was based on the requirement statement found in the FY99-03 Defense Planning Guidance This document, issued by the Secretary of Defense, provides firm guidance in the form of goals, priorities, and objectives, including fiscal constraints, for the development of the Program Objective Memorandums by the Military Departments and Defense agencies. Also called DPG.  (DPG DPG

). Unfortunately, the air-refueling requirement was omitted from the FY00-05 and FY01-05 DPG. This omission also eliminated the basis used for determining the tanker requirement.

The current FY01-05 DPG directs the Air Force to program "to sustain at least the current air-refueling support forces (KC-10 and KC-135 aircraft) through the FYDP FYDP Five-Year Defense Program
FYDP Five-Year Defense Plan
FYDP Fiscal Year Defense Plan
FYDP Future Years Defense Program/Plan
 (Future Years Defense Plan) period." This document no longer contains an actual "requirement" but a fiscally constrained statement that equals the current capability. Primarily due to a large number of PMAI PMAI Photo Marketing Association International
PMAI Primary Mission Aircraft Inventory
PMAI Photographic Manufacturers Association International
 (Primary Mission Aircraft Inventory) aircraft (547 KC-135s and 59 KG-l0s), it is widely assumed that tanker support will be available for all contingencies. However, depending upon the scenarios addressed, previous studies have identified significant capability shortfalls in both aircrews and aircraft. (35)

One-for-One Replacement

AMC planners assume a one-for-one replacement of the KC-135 with the KC-X. While a large requirement for aircraft availability exists, no aircraft replacement in recent history has been procured on a one-for-one basis. In fact, the actual procurement numbers of the KC-10, B-1, B-2, and C-17 have fallen well short of the numbers the Air Force said it needed. Robert Wall, in his article "USAF Reviews KC-135 Life Expectancy Life Expectancy

1. The age until which a person is expected to live.

2. The remaining number of years an individual is expected to live, based on IRS issued life expectancy tables.
," noted, "The number of KC-Xs the Air Force would buy to replace the more than 500 KC-135s is still undetermined." (36) Brigadier General Paul W. Essex, who oversees airlift and tanker acquisition programs, is wrestling with the KC-X procurement issue. He believes the KCX will be more efficient than the KC-135, allowing fewer aircraft to provide a greater amount of offload availability; "a new aircraft would be more efficient and allow for a higher utilization rate, which makes a one-for-one replacement unlikely." Yet, General Essex recognizes the need for booms in the air, which drive a larg e tanker fleet for aircraft availability. "A relatively large number of aircraft would be required because worldwide tanker support couldn't be accommodated with a small fleet." (37) General Robertson, addressing the House Armed Services Readiness Subcommittee in October 2000, emphasized the availability issues that arise when a large force is replaced by a smaller one: "Even though tonnage capabilities remain close to the same, we lose tremendous flexibility with so many fewer tails. The 135 C-17s can be only in half as many places as 270 C-141s." (38) The plan presented in AMC's Air Mobility Strategic Plan 2000 fails to account for the possibility that the KC-135 will not be replaced on a one-for-one basis by the KC-X and should investigate a solution that accounts for this very likely contingency.

Time Line for KC-X Delivery

AMC's Air Mobility Strategic Plan 2000 presents a KC-135 replacement model that assumes the design, testing, procurement, and training cycles for the KC-X will be complete by FY13. While replacing the KC-135 is near the top of the Air Force's priority list, a procurement cycle of this proportion has not been accomplished, in this short a time, for any major weapon system in recent history. As Secretary Peters pointed out, "We have no significant replacement programs on the books for our aging tankers." (39) Given the magnitude of this undertaking, AMC needs to account for the likely contingency that the KC-X will not enter service in FY13.

Unknown Service Life

Currently, the service life of the KC-135 is unknown. AMC's Air Mobility Strategic Plan 2000 points out that the major limiting factor A factor or condition that, either temporarily or permanently, impedes mission accomplishment. Illustrative examples are transportation network deficiencies, lack of in-place facilities, malpositioned forces or materiel, extreme climatic conditions, distance, transit or overflight rights,  for structural service life of the KC- 135 is corrosion. (40) The Air Force is conducting an economic, service-life study because previous studies failed to include corrosion as a factor. As a result of this study, AMC may have to accelerate the retirement of the KC-135 fleet and procurement of the KC-X. (41) Additionally, the current AMC replacement plan counts on the KC-135's continuing in service until FY40. In light of current plans, which indicate half the tanker force will still be KC-135s in FY25, AMC's retirement plan will need updating once the valid service life of the KC-135 is established.

Operations Tempo and Crew Manning

The combination of increased operations tempo and the lowest manning authorizations of any major weapon system causes problems for both retention and execution of wartime plans.

, North Dakota North Dakota, state in the N central United States. It is bordered by Minnesota, across the Red River of the North (E), South Dakota (S), Montana (W), and the Canadian provinces of Saskatchewan and Manitoba (N). , for example, KC-135 crews are deployed, on average, 137 days per year. This can aggravate crew-retention problems since crews are required to be away from their families for extended periods. Crew manning and operations tempo not only cause retention problems but also affect wartime plan execution. According to Lieutenant Colonel Scott Wilhelm, chief of the Modeling Branch in the AMC Office of Studies and Analysis, current KC-135 crew manning will leave the Air Force unprepared to meet wartime demands, "There would not be enough crews to do what we want to do." (42) During Operation Allied Force, the Air Force had to resort to an early presidential callup of KC-135 crews because there were not enough active-duty crews to meet the need. In fact, four reserve tanker units were activated under the Presid ential Selective Reserve Gallup to execute a 78-day air campaign. (43)

Summarizing the Air-Refueling Emergency

The previous discussion presents two factors critical to understanding the air-refueling emergency. First and foremost, the air-refueling shortfall is now. The KC-135 is an extremely old airframe, depot-level maintenance takes more than a year, aircraft availability is decreasing, and MC rates are falling. Second, the shortfalls in aircraft availability will continue after the KC-X is purchased. In all likelihood, AMC will not receive a one-for-one exchange for KC-135s, and the change out will not be instantaneous. Therefore, even if the KC-X delivers an increase in efficiencies that leads to greater fuel availability for the deployment phase of operations, it will not solve the aircraft availability issues associated with the employment phase of operations. Furthermore, KC-135s will still account for half the tanker fleet in 2025, and the problems associated with its maintainability will continue to be persistent. These factors necessitate a near-term solution to the air-refueling emergency.

Civilian Contract Air-Refueling: Innovative or Insane?

The single greatest power in the world today is the power to change. The most recklessly irresponsible thing we could do in the future would be to go on exactly as we have in the past ten or twenty years TWENTY YEARS. The lapse of twenty years raises a presumption of certain facts, and after such a time, the party against whom the presumption has been raised, will be required to prove a negative to establish his rights.

Karl W. Deutsch (48)

The most significant oversight in AMC's plans for addressing the air-refueling emergency is a failure to develop a near-term solution. The shortfall exists today, it will not improve tomorrow, it might get worse before the next generation tanker is delivered, and it is likely the shortfall will not improve entirely after the next-generation tanker is delivered. Secretary Peters described his concerns:

We have no significant replacement programs on the books for our aging tankers. It is not that we aren't going to have the tankers immediately, but what we are seeing on the KC-135 fleet are what appears to be an increasing mission-incapable rate due to technical surprises. ... These are the kinds of problems, which can put a whole fleet down, or 200 aircraft down overnight for a period of time and those are the kinds of worries we have. (45)

Solving the Air-Refueling Emergency

In August 1997, the commander in chief of USTRANSCOM, General Walter Kross, directed a feasibility study "A Feasibility Study" is an episode of the original The Outer Limits television show. It first aired on 13 April, 1964, during the first season. It was remade in 1997 as part of the revived The Outer Limits series with a minor title change.  for a civilian contract air-refueling proposal. Unfortunately, the CCAR proposal was limited to contracting for probe-and-drogue-type refueling only. The feasibility study The analysis of a problem to determine if it can be solved effectively. The operational (will it work?), economical (costs and benefits) and technical (can it be built?) aspects are part of the study. Results of the study determine whether the solution should be implemented.  concluded that a 1-percent increase in wartime capability would cost approximately $25.5M annually. (46) Because of the costs associated with a relatively small increase in wartime capability, excitement for the CCAR concept did not exist at USTRANSCOM or AMC. Undoubtedly, the CCAR proposal that USTRANSCOM studied did not present a viable solution to the air-refueling shortfalls. However, it provides four valuable lessons for a CCAR force. CCAR operations are feasible, must be capable of accomplishing boom and probe-and-drogue-type refuelings, are best suited for deployment and training operations, and are cost-effective.

CCAR Feasibility

First and foremost, the USTRANSCOM report established that CCAR operations are feasible. In its concluding remarks, the report states, "There are no known equipment or technical obstacles to preclude program development." (47) The accuracy of this statement was demonstrated in the fall of 2000 when Omega Air, Inc--an internationally based company specializing in aircraft sales, leasing, and parts--used a modified Boeing 707 to refuel a Navy FA-18C. (48) Omega received certification from the Federal Aviation Authority for the operation, contracted for its own insurance, and paid the Naval Air Warfare Center The Naval Air Warfare Center was a former U.S. Navy military installation located in Warminster, Pennsylvania and Ivyland, Pennsylvania.

The U.S. Navy purchased the grounds to establish this facility from the Brewster Aeronautical Corporation following its bankruptcy in the
 Aircraft Division $1M to certify the Boeing 707 for air-refueling operations. Following this successful demonstration, the Navy entered into a contract with Omega to provide civilian contract air refueling for its training operations. In addition to its 707s, Omega owns a fleet of about 20 DC-9s and DC-10s that could be modified for air-refueling operations, and recently, the president of Omega, Gale Matthe ws, voiced interest in purchasing KC-135s for use in Omega's air-refueling program. (49) Clearly, CCAR operations are feasible.

CCAR Operational Suitability

CCAR operations are best suited for deployment and training missions. USTRANSCOM' s Concept Development Report concluded, "Due to legal, policy, and liability considerations, the primary utility of contracted aerial refueling Aerial refueling, also called Air refueling or in-flight refueling (IFR) or air-to-air refueling (AAR) or (in the UK) tanking. Note that AAR also stands for "After Action Review" (de-briefing) and in aviation, IFR also stands for  is in training and deployment operations outside areas of hostilities." (50)

CCAR Capability Requirements

CCAR capability must include boom-type refueling capability, not just probe and drogue. The reasons for this are twofold. First, AMC annual probe-and-drogue missions do not exceed 2,000 hours. (51) These hours account for a small portion of the nearly 85,000 training hours allocated to tankers and, when divided among the 800 tanker crews, are highly valuable for currency and proficiency. AMC cannot afford to lose a significant portion of this training to a civilian contractor. Second, the preponderance of probe-and-drogue requirements arises during combat-strike operations for which civilian contract air refueling is not suitable. USTRANSCOM's finding about probe-and-drogue operations is valid: "AMC does not have a sufficient amount of peacetime probe-and-drogue refueling business to sustain a useful contracted AIR [air refueling] fleet." (52)

CCAR Operations are Cost-Effective

The report presented initial cost options for CCAR operations that ranged from $4,862 to $9,878 per flying hour and noted, "The figures are not meant to be analyzed from a contract perspective ... but rather as benchmarks for report purposes." (53) Since UTSTRANSCOM completed its report in 1999, Omega refined its cost estimate to about $5,500 per flying hour and recently entered into a contract with the Navy to provide air refueling for $5,995 per hour. (54) The KC-135R cost per flying hour was $2,232 in FY99 and increased by more than 50 percent between FY99 and FY01 to its current cost of $3,673 per flying hour, primarily because of maintainability issues. (55) While the cost projections Omega presented for CCAR operations are higher than reimbursement rates for KC-135Rs, it is proportionately lower than the KG-10s. According to Air Force Instruction (AFI AFI American Film Institute
AFI Awaiting Further Instructions
AFI Armed Forces Insurance
AFI A Fire Inside (band)
AFI Air Force Instruction
AFI Australian Film Institute
AFI Agencia Federal de Investigación
) 65-503, US Air Force Cost and Planning Factors, the FY01 reimbursement rate for KC-10s is $7,527 per flying hour. (61) At approximately $5,500 per flying hour, the cost of CCAR operations fits squarely in the middle of organic air-refueling costs ($3,673 to $7,527 per flying hour), and when compared to reimbursement rates for organic tankers, civilian contract air refueling presents a cost-effective option.

Contract Air Refueling: A Near-Term Solution

I think and think for months and years. Ninety-nine times, the conclusion is false. The hundredth time, I am right.

 records air refueling's contribution.

A robust aerial-refueling force provides numerous force multipliers that are critical in today's global environment. It gives virtually "unlimited" range to any air asset (bomber, fighter, airlift, special forces, or rescue) that has aerial refueling capability--U. S. or allied ... it gives military leaders tremendous flexibility in both planning and execution. It makes one fighter capable of doing the job of several by increasing the time it can stay aloft and the number of targets it can strike. It permits heavy airlift aircraft to carry greater payloads over much longer distances in significantly less time. An aerial refueling force makes all U. S. military forces (Army, Navy Marine, and Air Force) more influential and more capable. Aerial refueling is an incredible force multiplier. (57)

Civilian Contract Air Refueling: The Findings

Civilian contract air refueling is a unique concept that presents a near-term solution to AMC's air-refueling shortfall. The Air Force could realize three advantages from pursuing a CCAR capability. First, it would fill air-refueling deployment gaps in wartime plan deficiencies--now and in the future. Second, it would give receiver units a greater opportunity to maintain currency and proficiency at air-refueling operations. Finally, it would enhance air-refueling flexibility and improve airpower employment effectiveness.

CCAR Fills the Gap in Wartime Plan Deficiencies. AMC needs a cost-effective, near-term measure to fill the gap in wartime plans and relieve the peacetime operations tempo. As previously noted, the KC-135's increased depot-level maintenance cycles have decreased peacetime aircraft MICAP rates to almost 20 percent below those acceptable for wartime mission accomplishment. (58) Additionally, the service life of the KC-135 is still unknown, operations tempo is at an all-time high, and AMC says crew manning is at a level below that required for mission execution. (59) Finally, AMC does not have a plan to fill near-term requirements, and its long-term KC-135 replacement plan ignores the historical and financial realities of garnering a one-for-one replacement for any major weapon system. A CCAR force would help eliminate these shortcomings.

CCAR Increases Training Opportunities. CCAR capability serves two roles: force deployment and training enhancement. In its force deployment role, it would be available to relieve air-refueling tanker taskings and ensure AMC's ability to execute wartime plans. Additionally, it could be used to relieve tanker taskings during air expeditionary force Deployed US Air Force wings, groups, and squadrons committed to a joint operation. Also called AEF. See also air and space expeditionary task force.  swap-outs, giving overtasked tanker crews a relief from the demanding operations tempo. In the training role, it is available to meet receiver air-refueling currency and proficiency requirements.

CCAR Increases Airpower Flexibility. Air refueling, when properly employed, enhances, enables, and multiplies the strategic, operational, and tactical effects of any air operation. (60) Air refueling allows airpower forces to increase levels of mass, surprise, economy of force, and security and concentrates more assets for offensive and defensive operations. Since its inception, air refueling has been the force multiplier that is inherently critical to achieving the rapid, global mobility essential to maintaining deterrence--first line of national security for the United States. Moreover, air refueling's second role, force enhancement, is critical to winning the nation's wars--the bottom line of national security. (61) Increasing the availability of air-refueling assets with a CCAR capability is of insurmountable value to the flexibility required in peacetime operations and wartime mission execution. Undoubtedly, a CCAR capability would increase that flexibility and capability.

Civilian Contract Air Refueling: The Desired End State

Given the magnitude of air refueling's importance to national security and the dwindling state of air-refueling capability, the recommendation is singular: USTRANSCOM, in conjunction with AMC, should actively pursue a civilian contract air-refueling capability.

                           * Reduces force-protection concerns and
                             number of aircraft required for
                             defensive operations, which frees
                             aircraft for offensive operations.
