USAF Agile Combat Employment: Forward Basing Fighters for Pacific Warfighting
The vast expanse of the Pacific Ocean has become the modern battlefield’s most challenging theater, where traditional military strategies meet their match against advanced threats. Gone are the days when air power could operate from massive, fixed installations with impunity. Today’s reality demands something entirely different: the ability to disperse, adapt, and strike from unexpected locations across thousands of miles of ocean.
The United States Air Force has answered this challenge with Agile Combat Employment (ACE), a revolutionary approach that’s reshaping how fighter aircraft deploy and operate in contested environments. This isn’t just a tactical adjustment — it’s a complete reimagining of air power projection that could determine the outcome of future conflicts in the Indo-Pacific region.
What is Agile Combat Employment (ACE)?
Defining ACE: A Proactive and Reactive Scheme of Maneuver
According to Air Force Doctrine Note 1-21, Agile Combat Employment is “a proactive and reactive operational scheme of maneuver executed within threat timelines to increase survivability while generating combat power.” This official definition captures the essence of a concept that prioritizes speed, adaptability, and survivability over the traditional model of operating from large, heavily fortified bases.
The core objectives of ACE are straightforward yet revolutionary: increase aircraft survivability by making them harder to target, maintain the ability to generate combat power even when dispersed across multiple locations, and complicate enemy decision-making by presenting them with a constantly shifting array of potential targets.
This approach represents a fundamental shift in military thinking. Instead of concentrating forces at a few well-defended locations, ACE spreads them across numerous smaller, more agile positions that can be rapidly established, used, and abandoned as tactical situations demand.
The Strategic Imperative: Why ACE is Crucial for the Indo-Pacific
The numbers tell a stark story about modern air power vulnerability. The USAF operated from 93 air bases during World War II, but today maintains only 33 permanent overseas installations — a 65% reduction in global footprint. While this consolidation made sense during peacetime, it’s created a dangerous vulnerability in an era of advanced threats.
Modern adversaries have developed sophisticated intelligence, surveillance, and reconnaissance (ISR) capabilities combined with long-range precision fires that can devastate traditional air bases. As Mark Gunzinger, Director of Government Programs and War Gaming at the Mitchell Institute for Aerospace Studies, bluntly states: “The best place to kill an enemy’s air force is on the ground.”
This reality is particularly acute in the Indo-Pacific, where potential adversaries have invested heavily in anti-access/area denial (A2/AD) capabilities specifically designed to neutralize American air power at its most vulnerable moment — while parked on predictable airfields.
The Core Principles of ACE for Fighter Operations
Dispersal and Survivability: Avoiding the “Ground Target” Dilemma
Traditional air operations concentrate valuable aircraft at major installations, creating what military strategists call “lucrative targets.” A single successful strike on a major air base can eliminate dozens of aircraft, pilots, and support personnel in one devastating blow. ACE fundamentally changes this calculus by scattering assets across multiple locations, forcing adversaries to divide their attention and resources among numerous smaller targets.
Fighter aircraft operating under ACE principles don’t just disperse randomly — they follow carefully planned patterns that maximize their operational effectiveness while minimizing their vulnerability. This might mean operating from a combination of established airfields, repurposed civilian airports, and even temporary strips carved from suitable terrain.
Generating Combat Power from Austere Locations
The true test of ACE isn’t just survival — it’s maintaining the ability to fight effectively from locations that lack the comprehensive infrastructure of major air bases. Fighter aircraft require fuel, ammunition, maintenance, and command connectivity to remain combat-effective. ACE proves its worth by demonstrating that these needs can be met even in austere environments.
Small teams of multi-capable airmen become force multipliers, performing tasks that would traditionally require dozens of specialists. Expeditionary equipment replaces permanent installations, and innovative logistics solutions ensure that fighters can maintain high sortie rates even when operating from locations that appeared on no military map just days before.
Speed, Agility, and the OODA Loop: Outpacing the Adversary
Military strategist John Boyd’s OODA Loop — Observe, Orient, Decide, Act — becomes critical in ACE operations. The side that can complete this cycle faster gains decisive advantages. ACE enables air forces to compress their decision-making timelines while forcing adversaries to grapple with constantly changing scenarios.
When fighter aircraft can appear at new locations faster than enemy intelligence can track and target them, they gain what amounts to tactical invisibility. This speed advantage compounds over time, as adversaries struggle to maintain accurate targeting data on dispersed, mobile forces.
How ACE Enables Forward Basing of Fighters in the Pacific
Distributed Operations and Minimal Footprint for Fighter Jets
The Pacific’s geography — thousands of islands scattered across millions of square miles of ocean — actually becomes an advantage under ACE doctrine. What once seemed like an impossible logistics challenge transforms into the ultimate dispersal opportunity.
Fighter aircraft operating under ACE principles can utilize everything from major allied air bases to small civilian airstrips on remote islands. The key is maintaining a minimal footprint that can be established quickly and abandoned without significant loss if threatened. This might involve pre-positioning fuel and munitions at multiple locations, or developing the capability to rapidly transport these essentials by air when needed.
Multi-Capable Airmen (MCAs): The Backbone of Fighter Agility
Traditional air operations rely on large teams of specialists — fuel system technicians, weapons loaders, communications experts, and dozens of others. ACE turns this model on its head by training multi-capable airmen who can perform multiple critical functions.
An MCA might arrive at a remote airstrip and within hours establish fuel pumping capabilities, set up secure communications with higher headquarters, and prepare to service arriving fighter aircraft. These versatile professionals become the human foundation that makes ACE possible, enabling small teams to accomplish what previously required large organizations.
The training for MCAs is intensive and ongoing. They must master not just multiple technical skills, but also the ability to make rapid decisions in austere environments where backup and supervision may be hours or days away.
Rapid Refueling and Resupply: Sustaining the Fight
Fighter aircraft are fuel and ammunition-intensive platforms. An F-35 Lightning II carries approximately 18,500 pounds of fuel internally, while an F-15E Strike Eagle can carry over 23,000 pounds. Traditional operations assume abundant fuel supplies at established bases, but ACE operations must plan for scenarios where every gallon counts.
Expeditionary fuel systems become critical enablers. These might include portable fuel bladders that can be rapidly deployed by cargo aircraft, mobile refueling trucks that can operate on minimal infrastructure, or even innovative solutions like fuel barges that can supply island airstrips directly from the sea.
Ammunition presents even greater challenges. Modern air-to-air missiles and precision-guided munitions are complex, expensive systems that require careful handling and storage. ACE operations develop solutions for rapidly moving these weapons to forward locations and maintaining them in environments that lack climate control and sophisticated security systems.
Adaptive Command and Control (C2) for Dispersed Fighter Assets
Coordinating fighter operations across vast distances with minimal infrastructure requires revolutionary approaches to command and control. Traditional C2 relies on large, sophisticated communications centers that are themselves vulnerable to enemy action. ACE demands more resilient, distributed solutions.
Modern fighter aircraft carry sophisticated communications and data-sharing equipment that enables them to coordinate directly with each other and with higher headquarters. Satellite communications provide global connectivity, while advanced data links allow fighters to share targeting information and coordinate attacks in real-time.
Ground-based C2 elements become smaller and more mobile. Instead of massive command bunkers, ACE employs small teams with portable equipment that can establish command capabilities anywhere with suitable communications infrastructure.
Leveraging Diverse Operating Locations: From Main Bases to Austere Airfields
The Pacific offers an unprecedented variety of potential operating locations for fighter aircraft. Major allied air bases provide full-service capabilities when available, but ACE’s true advantage lies in its ability to utilize less obvious alternatives.
Civilian airports throughout the region often have runways suitable for military aircraft and basic fuel and maintenance facilities. With minimal preparation, these locations can support fighter operations for limited periods. Some facilities might require only the addition of secure communications and ammunition storage to become viable military airstrips.
Even more austere locations become possible with proper planning. Many Pacific islands have airstrips built during World War II that, while not currently active, could be rapidly restored to operational status. In extreme scenarios, suitable beaches or flat terrain could serve as temporary operating surfaces for aircraft equipped with appropriate landing gear modifications.
ACE in Action: Exercises and Real-World Application in the Pacific
Tropic ACE and Pacific Iron 21: Testing Fighter Forward Basing
Exercise Tropic ACE has become the proving ground for Pacific Air Forces’ ACE concepts. These exercises demonstrate the practical reality of deploying fighter aircraft to austere locations across the Pacific, testing everything from initial deployment logistics to sustained combat operations.
During these exercises, fighter aircraft deploy to locations they’ve never operated from before, often with minimal advance preparation. Teams of multi-capable airmen establish basic operations capabilities, while the aircraft themselves prove their ability to maintain combat effectiveness despite the challenging conditions.
Operation Pacific Iron 21 took these concepts even further, demonstrating sustained operations across multiple locations simultaneously. Fighter aircraft rotated between different bases, maintaining high operational tempos while proving that ACE concepts work not just in theory, but in the complex reality of Pacific operations.
Geopolitical Context: Deterring Aggression in Great Power Competition
ACE serves a crucial deterrent function in the current era of great power competition. Potential adversaries must now plan not just for attacking a few well-known air bases, but for dealing with fighter aircraft that could appear anywhere across the vast Pacific theater.
This uncertainty complicates enemy planning and forces them to spread their defensive resources more thinly. Instead of concentrating anti-aircraft systems around a few major bases, adversaries must now consider threats from dozens of potential locations, many of which may not even be active until hostilities begin.
Strategic Impact for Pacific Warfighting
Complicating Enemy Targeting and Decision-Making
From an enemy perspective, ACE creates a targeting nightmare. Intelligence systems that once needed to track a few dozen major installations must now monitor hundreds of potential locations across thousands of miles. This exponential increase in complexity strains enemy resources and creates opportunities for friendly forces to exploit.
The psychological impact shouldn’t be underestimated either. Enemy commanders facing ACE operations must plan for threats that could materialize anywhere within range of their forces. This uncertainty can lead to defensive postures that reduce their own operational flexibility and effectiveness.
Enhancing Deterrence and Credibility in the Indo-Pacific
ACE demonstrates American commitment to maintaining air superiority across the Pacific theater even in the face of advanced threats. This capability assures allies that American air power remains viable and relevant despite enemy advances in anti-access technologies.
The ability to rapidly establish fighter operations at new locations also provides unprecedented flexibility for responding to crises. Whether supporting humanitarian operations after natural disasters or responding to military aggression, ACE-enabled forces can establish presence where needed rather than being constrained by existing base locations.
Strengthening Alliances and Partnerships in the Region
ACE operations inherently require close cooperation with regional allies and partners. Many of the airfields and facilities that enable dispersed operations belong to allied nations, creating opportunities for enhanced military cooperation and interoperability.
Joint training exercises under ACE concepts build trust and understanding between allied forces. When American fighters train alongside allied aircraft at diverse locations, they develop the personal relationships and procedural understanding that prove crucial during actual operations.
Challenges and Future of ACE for Fighter Basing
Overcoming Logistical Hurdles in a Contested Environment
The logistics of supporting distributed fighter operations remain one of ACE’s greatest challenges. Traditional military logistics assume secure supply lines and predictable demand patterns. ACE operations must plan for scenarios where supply lines are under constant threat and demand can spike unpredictably at any location.
Innovation in logistics delivery becomes essential. This might include developing new classes of cargo aircraft optimized for austere airstrip operations, creating more efficient ammunition and fuel packaging systems, or even exploring autonomous delivery systems that can operate in contested environments.
Training and Cultural Shifts for a Distributed Force
ACE requires fundamental changes in how air force personnel think about their roles and responsibilities. The traditional model of specialized technicians working at well-equipped bases gives way to versatile professionals who must adapt to constantly changing environments and requirements.
This cultural shift extends beyond technical training to include leadership development, decision-making skills, and the ability to operate independently for extended periods. Future airmen must be comfortable with uncertainty and capable of innovation when standard procedures don’t address novel situations.
Technological Advancements and Integration
Future ACE operations will likely incorporate advancing technologies in artificial intelligence, automation, and connectivity. AI systems might optimize aircraft routing and logistics scheduling across dispersed locations, while automated systems could reduce the human footprint required at forward operating locations.
Advanced connectivity solutions could enable even more distributed operations, with fighter aircraft coordinating seamlessly across vast distances and sharing sensor data in real-time to create a comprehensive picture of the battlespace.
Conclusion: The Evolution of Air Power Projection in the Pacific
USAF Agile Combat Employment represents more than just a new operational concept — it’s a fundamental reimagining of how air power operates in contested environments. By enabling fighter aircraft to deploy and operate from diverse, austere locations across the Pacific, ACE ensures that American air superiority remains viable even against the most advanced threats.
The transformation isn’t without challenges, but the exercises and real-world applications already demonstrate ACE’s potential. As the concept continues to evolve and mature, it promises to provide the foundation for maintaining peace and stability across the Indo-Pacific region for decades to come. The future of Pacific warfighting will be shaped not by the forces that can build the biggest bases, but by those that can fight effectively from anywhere they’re needed.
