“America’s not funding us to be a large Air Force anymore.”- Air Force Secretary Michael Wynne, 19 September 2007
The Air Force is simultaneously getting smaller and busier. In doing so it's entering uncharted territory. Or is it really uncharted territory? For the Airmen who serve in low density/high demand (LDHD) weapon systems, smaller and busier has been ‘ops normal’ for some time.
In the late 1990s the Air Force concluded it lacked enough of certain weapon systems to adequately fill the new Air Expeditionary Force (AEF) deployment structure. These systems, which came to be known as LDHD, operate under different pressures and conditions than ‘right sized’ forces. As a result, observable behaviors and characteristics unique to these communities have emerged over time. In this paper, I lay out eleven of these unique traits.
These traits provide a vocabulary for awareness and understanding of why LDHD systems emerge, perpetuate, and behave in certain ways. This paper provides some tools for managing short term effects in LDHD organizations, and explores the implications of having significant numbers of weapon systems exhibiting these traits within the Air Force.
Officially designated LDHD forces are figuratively the ‘canary in the coal mine’ . As the Air Force continues to ‘right size’ and taskings mount, Airmen should pay closer attention and draw lessons from what their LDHD brethren are experiencing.
LDHD Defined.
The Air Expeditioary Force(AEF) structure organizes forces around capabilities and provides deployment predictability, and fairness. Originally, it called for 90 days of temporary duty every 15 months. In some cases, there were not enough of some systems to supply every AEF. These LDHD forces were called enablers. The Joint Staff has officially recognized LDHD weapon systems since 1996 and attempted to manage them with the Global Military Force Policy (GMFP). This policy requires war fighting commanders request needed capabilities, not specific platforms. Annually, each service nominates its systems to be defined as LDHD under GMFP.
According to law:
“High-demand, low-density military capability (forces are) combat, combat support or service support capability, unit, system, or occupational specialty that the Secretary of Defense determines has funding, equipment, or personnel levels that are substantially below the levels required to fully meet or sustain actual or expected operational requirements set by regional commanders.”
This explanation says we don’t have enough, but enough of what? The Air Force has acknowledged several LDHD weapons systems, including RC-135 Rivet Joint, E-8 JSTARS, U-2, E-3 AWACS, HH-60G, and AC-130.
AEF deployments have increased to 120 days every 20 months and the force is still shrinking.With this in mind, many non-LDHD commanders will say they don’t have enough assets to do their mission. This alone, however, doesn’t make a weapon system LDHD.
11 Traits of an LDHD Force.
1. LDHD forces do not emerge by design, but underestimating demand, not providing adequate resources, or through management.
LDHD forces arise unintentionally, whether from underestimated demand, under-allocated resources, mismanaged programs, or a combination of all three. The most important thing to understand about demand is it an uncontrollable variable. ‘Density’ results from policy, programming and budgeting decisions, but ‘demand’ lies with the actions of our adversaries. Therefore, demand is often poorly forecast. The impact may not be apparent for years until events force a reassessment of accepted assumptions. Density is defined, demand depends.
Under-allocated resources are perhaps the most common reason LDHD forces emerge. Budgets are cut, programs are delayed, production lines prematurely close - the list goes on.
Sometimes LDHD systems emerge because they are mismanaged. A timely example is the F-22 Raptor. The Air Force states it requires over 381 planes. Policy makers concluded 183 will suffice. Either senior Air Force officials have grossly miscalculated demand by a factor of two or an LDHD weapon system has been born; only time will tell.
Policymakers recognize there are not enough of these forces but choose to perpetuate the status quo.
If a system is recognizably in short supply one would logically assume policymakers would act quickly to increase force strength. Unfortunately, in today’s grim budget realities this is not always true. Instead, policy makers often choose not to increase forces to meet demands. They may plan force increases, but don’t follow through. This usually remains the case until some event forces the issue.
The F-22 Raptor example applies here as well. Senior policymakers, not the Air Force, are quite satisfied with only 183 aircraft. However, the recent F-15 crash due to structural cracks resulted in the indefinite grounding of 40% of the F-15 fleet. This one event turned a normal mission area, air superiority/air dominance, into an LDHD mission area overnight. The status quo changed and may have reopened the case for buying new Raptors.
Most weapon systems can avoid from falling into the LDHD trap by policy makers consciously addressing traits 1 & 2.
2. LDHD weapons systems are expensive, highly capable platforms which are few in numbers and difficult, if not impossible, to replace.
LDHD systems fall into two broad categories: antiques and exotics.
Antiques are no longer built. Like a classic car, once wrecked it’s gone forever; and just like an old car, sustainment becomes increasingly expensive. Updating antique systems is also very expensive. For example, the C-5 fleet is undergoing upgrade and life extension modifications at a current cost of $83 million per aircraft. If not replaced in a timely manner, right-sized antique systems may become LDHD through wear and tear. The recent F-15 grounding is not the only example of this. The C-130 fleet instantly, if temporarily, became an LDHD asset when in 2005 about 100 C-130Es where grounded due to wing cracks.
While exotics may have open production lines, they’re so expensive or complex they are only built at low rates. For example, it takes 30 months to make a single F-22. If we quickly needed another 180 F-22s we wouldn’t get them for quite some time.
Antiques and exotic numbers are static or cannot be quickly surged. They may not be classified as LDHD for current requirements but may quickly become LDHD in the event of unexpected and sustained contingencies. As we will see, this contributes to trait.
3. When increasing resources or decreasing demands is not possible, LDHD forces compensate in other ways.
Translation: Doing more with less.
LDHD compensatory behavior occurs at the highest levels. GMFP itself is a compensatory measure. It establishes a protocol to help manage the personnel tempo (PERSTEMPO) of highly tasked units. Like other compensatory measures, it eases the pain but doesn’t fix the underlying problem.
The Air Force often compensates in lieu of aggressively increasing numbers of LDHD weapon systems. To gain efficiencies with the service devises other options such as increasing simulator capability and capacity, increasing manpower-to-platform ratios, using suitable substitutes, using retention tools such as bonuses, and using more reserve forces. Efficiency is generally a good thing but can sometimes have unintended consequences, as we will see when reserves are routinely used as operational forces. I will discuss this more under trait 10.
Management tools such as Total Quality Management and Lean processes naturally gain momentum in LDHD organizations. In many cases these programs are successful, resulting in smaller but more capable forces.
An emerging compensatory behavior is outsourcing to private contractors. While a mainstay for missions like logistics support and security, this phenomenon is just starting to creep into air operations. We have yet to see long term consequences.
Unfortunately, proponents of efficiency processes forget that the military, unlike industry, has very different funding processes. Industry can better flex to dynamic market realities and tap new resources. Militaries, however, exist within government budgeting realities. In government, the reward for doing more with less is getting less to do more.
Another compensatory behavior is leveraging new technologies to increase the performance of existing forces. Stealth and information technology are two good examples. The downside is that these forces become very expensive. This is a driving factor in trait 3 and contributes to traits 5, 6, and 7.
4. LDHD forces rely on precision (or precision-effects) instead of mass.
As LDHD forces become more sophisticated and efficient, they come to rely on precision effects instead of using mass to achieve desired outcomes. AFDD-1 defines “precision engagement” as the ability to command, control, and employ forces to cause specific strategic, operational, or tactical effects.
Precision and survivability are inseparable. The more effective a given weapon system is, the fewer are needed. This means not only are fewer munitions required to achieve the desired effect, but fewer platforms are required to reach the objective. If fewer are needed, then fewer are bought and retained. When combined with trait 4, this drives LDHD systems into downward spirals to the point where mass is no longer an option. Precision/precision-effect is no longer just one of many tools, it’s the only option. The weapon system becomes too rare and expensive to accept any losses. Systems such as the E-3, E-8 and the B-2 fit this description.
Originally, the Air Force planned to buy 132 B-2 Spirit bombers. As originally designed, it had only half the ‘precision’ equation, survivability, as it could only deliver non-precision conventional bombs or nuclear weapons. Eventually, only 21 B-2s entered service. Now the Spirit can deliver precision guided munitions, adding precision to survivability. With only 21 bombers, the B-2 cannot achieve mass as a delivery platform. In other words, if for some reason its stealth capability were compromised it could not use strength of numbers to reach its objective. Precision and survivability are the only options.
AFDD-1 also says, “Mass is an effect that air and space forces achieve through effectiveness of attack, not just (emphasis added) overwhelming numbers.” Yes, but sometimes mass means just that, overwhelming numbers.
Trait 5 logically combines with trait 3 to create the next trait.
6. LDHD forces are not optimized for defensive operations.
LDHD forces are delicate, they lack mass (as measured by sheer numbers of weapons platforms) and depth (as measured by the ability sustain and regenerate losses).
LDHD weapons systems create LDHD, or narrow, training pipelines and logistics chains. They are pared and tailored to meet the needs of small communities with few platforms. Training pipelines are discussed further under trait 8.
These forces have narrow logistics chains since they are few in number, such as exotics. In the case of antiques, they are no longer built and any production is limited to component replacement parts. At this point trait 4 becomes a factor. Logistical compensatory behavior seeks to shift supply costs to commercial suppliers through strategic sourcing initiatives such as direct-vendor delivery and vendor-managed inventory. These techniques reduce inventory costs by reducing inventories themselves, relying on “just in time” deliveries. Traditionally, large military inventories protect against uncertainty by forming a strategic reserve. These practices yield measurable savings, but remove mass from logistic chains, making them even more narrow and susceptible to external forces out of military planners’ control.
Unfortunately, this very narrowness makes these systems easier to target. They are few in number and often consolidated in centralized locations. Centralization and narrowness combine to present fewer “critical nodes” for potential enemies to target. Antique weapon systems are critical nodes as adversaries need only target the system itself. Worse yet, narrowness and centralization make LDHD weapon systems uncomfortably susceptible to weapons of mass destruction.
LDHD platforms are sometimes lynchpin systems, or critical enablers for other non-LDHD weapon systems. Most C2ISR systems, like the E-3 AWACS, are examples of this. When a lynchpin system is lost it can simultaneously and seriously degrade numerous other systems.
Age is a threat. Being delicate, LDHD forces are highly susceptible to random events. The F-15 and C-130 examples show how unexpected technical problems can be just as disastrous as enemy action. Nature can also inflict disproportionate damage on an LDHD force, such as a tornado sweeping across a ramp of irreplaceable antiques.
LDHD forces cannot sustain losses; they fare poorly in defensive operations or attrition warfare. They make enticing targets for potential adversaries and are susceptible to Murphy’s Law.
7. LDHD forces are inherently offensive in nature.
If a force is not best suited for defense it had better be good at offense. Weapon systems achieving precision-effects and emphasizing platform-based survivability are, by nature, good at taking the fight to the enemy. In other words, the more survivable a given platform, the better suited it is to attack. This is a natural outcome of traits 4 and 5, which create effective and efficient weapon systems. They are ‘born to attack,’ or enable other systems to attack. This may be why the Air Force, which believes airpower is inherently offensive, has many LDHD systems. This, however, is only half of the offensive equation.
Being delicate, LDHD forces may not survive an attack and still be viable. Traits 3 and 6 reinforce the old cliché the best defense is a good offense. Since LDHD forces are not suited for sustained conflicts or attrition combat, adversaries must be defeated in short order. Optimally, these forces are best used preemptively.
8. LDHD personnel are highly trained specialists requiring extensive training and are difficult to replace.
As briefly mentioned in trait 6, LDHD forces have narrow training pipelines. They cannot readily surge to meet increased personnel demands.
First, they’ve been tailored to meet smaller production quotas. LDHD weapon systems breed LDHD training units.
Second, they are often highly selective, draw from small pools of qualified candidates who are subjected to long periods of expensive training, and possibly have high washout rates. Special operations forces are good examples.
Third, because they are part of an LDHD community, there’s no excess of platforms or personnel. Training surges usually occur during contingencies, when aircrew and aircraft are needed in the field. It’s therefore unlikely that training units will get additional resources when they need them most. This scenario played out in the buildup to OIF, when there where no E-3 AWACS to spare. During that time, when training was critically needed, no extra aircraft were available.
Trait 8 stands apart from trait 6 due to its dynamic relationship with the next trait.
9. LDHD forces have greater difficulty retaining personnel.
High workload is a natural result of high demand. There are many ways to measure workload, one of which is PERSTEMPO, the amount of time personnel engage in duties that preclude spending off-duty time at home station. However, workload is not a good indicator of an LDHD weapon system. First, there isn’t a standard PERSTEMPO definition agreed upon by all the services. Second, most commanders probably think their units are overworked.
Wouldn’t high workload impact retention? The answer is yes. A 1999 RAND study found “further additions of long or hostile duty…incrementally reduce(d) reenlistment propensity…” If such a relationship exists then shouldn’t there be an objective metric? Follow the money.
Weapon systems with high levels of career fields receiving reenlistment and retention bonuses are probably LDHD. For example, 27% of the enlisted career specialties receiving selective reenlistment bonuses are associated with LDHD systems, such as flight engineer, pararescue, and airborne battle manager. In fact, retirees and reserve component members from LDHD weapon systems can switch to active duty and earn a hefty bonus. Another indicator is the presence of mandatory retention measures to prevent members from separating or retiring.
There are always exceptions. Some stressed units have good retention. Intangibles, like unit esprit de corps, can keep people in the fight when incentives can’t.
Combined, traits 8 and 9 indicate brittleness unique to LDHD forces. Their training pipelines are narrow, they cannot effectively surge when necessary, and they have difficulty retaining people. Simply put, if you use them too much, you’ll break them.
10. LDHD forces have fewer reserves of equipment and personnel; if they exist, they are operational reserves.
“It's [active component] simply too shortly manned to do the many tasks that are out there and do them in a way that doesn't put stress on both the active force and the reserve force.”
- Rep. John McHugh, House Armed Services Personnel Subcommittee Chairman May 2005
Trait 4 states LDHD commanders compensate for not having enough of what they need. One way is to use strategic reserves for current requirements. This is like paying today’s bills with savings.
As demand increases, reserves are employed with increasing frequency as operational reserves, forces used regularly to support active duty military operations at home and abroad. If a community cannot meet sustained AEF obligations without the reserve component, then it has an operational reserve.
Logically, operational reserves have higher PERSTEMPO. Therefore, traits 8 & 9 would increase reserve component brittleness as retention and turnover place further stress on narrow training pipelines.
Sometimes, reserve forces are disbanded altogether so needed equipment can be used by active forces. In the long run this conversion strategy, cannibalization, hurts both the reserve and active components.
Reserve manpower is usually lost or transferred to other weapon systems – it rarely converts directly to the active component. This further stresses narrow training pipelines, per trait , as they struggle to increase active manpower to fill the converted reserve platforms. Fewer reserve units now exist to retain separating active duty personnel, making Trait 9 even worse. Subsequently, their experience is lost.
If a weapon system has no strategic or operational reserve, or is cannibalizing its reserves then it has attained operational overreach. This exacerbates Trait 3 and 6. These forces may be overwhelmed in the event of unexpected and sustained contingencies - a rainy day comes and the savings account, the strategic reserve, has been spent.
11. LDHD forces are risk averse.
No man is worth his salt who is not ready at all times to risk his body, to risk his well being, to risk his life, in a great cause."
- Theodore Roosevelt
More so than properly balanced forces, LDHD communities foster heightened cultures of risk management. LDHD commanders are understandably reluctant to risk these precious assets. Risk management is a cornerstone in any military organization, but LDHD communities sometimes take it a step further and become risk averse. Risk aversion surfaces operationally, culturally, and strategically.
Operational risk aversion manifests itself with several behaviors. On their own, these behaviors are not always wrong, but in risk averse organizations they are often applied inappropriately. First, the ‘most-conservative response rule’ (always follow the most conservative course of action) is usually taken, even when other properly risk-managed courses of action would be more effective. Next, decisions and subsequent actions are delayed until every possible variable is known, considered, and weighed, even in time critical situations. Decision authority is often pushed to higher levels, even when not appropriate.
Often regulatory overhead increases to the point where instructions become overly detailed and inflexible. In extreme situations, decisions may be delayed to the point of self-imposed operational paralysis.
Culturally risk averse organizations can no longer find creative ways to meet mission demands. They operate in ‘survival mode’ with fatigued personnel unwilling to allocate precious resources to effect change, no matter how promising. As these organizations become more conservative, there are fewer incentives for change. Finally, communication breaks down as PERSTEMPO increases; time and opportunities to exchange ideas decrease as workload increases; and creative thinking withers.
Long-term planning suffers in creatively barren organizations. Strategically risk averse units become stagnant, focus on immediate goals and are less receptive to new ideas. At this point an LDHD organization can no longer compensate as detailed in trait 4 and is in true crisis. When taken to an extreme, these organizations may become risk intolerant - in practice they accept no risk except those explicitly defined in regulatory guidance. In such cases, personal initiative and autonomy are discouraged in all instances, even combat.
Using the 11 Traits.
Unlike the official static definition, these traits are comprehensive, dynamic, and interrelated. But what good are they? First, they give Airmen, especially those in non-designated LDHD weapon systems, awareness of a problem. Because that’s exactly what LDHD is: a problem.
Awareness is necessary for understanding. These traits provide a vocabulary to understand why and how LDHD forces behave the way they do.
With awareness and understanding, commanders can then manage the acute effects inherent to LDHD systems. For starters, commanders can identify the policies which create and perpetuate their weapon system’s LDHD status. They can also accurately quantify weapon system delicateness and brittleness; good metrics are critical when requesting additional resources. Commanders can also gain organizational and technological efficiencies without falling into the trap of increasing system delicateness. Policy makers can reduce weapons system brittleness by bolstering training pipelines and aggressively addressing retention. Finally, commanders can avoid the risk-aversion trap by reevaluating decision making and risk management processes. All of these are short-term fixes and are an extension of trait 4. They don’t solve the chronic problem.
Sometimes, there’s no suitable substitute for having more. The only real fix for chronic LDHD weapon systems is to increase force strength or decrease demand, and decreasing demand is not always an option. Why should policy makers concern themselves with this if they’ve accepted LDHD forces as a fact of life?
The more LDHD weapon systems a force has, the more that force is in a state of strategic overreach. The Global War on Terror (GWOT) is increasing pressure on both LDHD and non-LDHD communities. Now the Air Force is shrinking, cutting both personnel and weapon systems under the Force Shaping initiative. As end-strength glides to 316,000 and the GWOT continues unabated, Airmen serving in weapon systems not officially defined as LDHD will find they share more and more in common with their LDHD brethren. Unabated, it becomes systemic and the entire service will begin to exhibit LDHD traits, becoming an LDHD Air Force. Such an air force would be overextended and highly vulnerable.
“Therefore, a smaller army that is inflexible will be captured by a larger one.”
- Sun Tzu
Conclusion
These 11 traits are just that, traits, not quantifiable metrics. They are theories, not laws, of how these organizations behave. Overworked units, with or without an LDHD designation, need a lexicon from which to work. This conceptual framework gives form and voice to what many Airmen are experiencing but haven’t been able to express. In this light I hope this will help readers see if their weapon system is effectively LDHD or not.
As stewards of American airpower every Airman must look to the future. For those finding themselves in LDHD organizations, it’s important not only to be aware of the reasons and implications of being in an overextended weapon system, but what can be done about it. With awareness comes responsibility. In this paper, I detail some measures commanders can implement at the unit level[, but the real work is at the policy-making level. The Air Force has been at war for 17 years and is approaching its smallest force level since 1947. This alone justifies more detailed studies on the long term health, culture, and viability of LDHD communities. More information is needed if we are to avoid becoming an LDHD Air Force.
I hope this generates open discussion and dialogue about what happens when too few have been asked to do too much, with too little, for too long.
