U.S. Air Force ACE: Preparing Aircraft for a New Reality
Agile Combat Employment: A Doctrinal Shift for a Contested Era
Can an air force built around massed formations and permanent bases learn to fight from a network of improvised runways, austere roads and tiny island strips — all while under threat from precision missiles, electronic attack and cyber intrusion? The U.S. Air Force answered that question with Agile Combat Employment, a 2021 doctrine intended to make aircraft and their crews harder to find, faster to move, and more resilient once they arrive. Agile Combat Employment is less a new weapon than a new way of thinking: dispersal, speed, devolved decision-making and redundancy replace reliance on single, hardened hubs.
Agile Combat Employment recognizes the strategic shift toward great-power competition. Adversaries now field anti-access/area-denial capabilities, long-range precision fires, advanced sensors and electronic warfare suites that make large, static bases attractive targets. The doctrine seeks to complicate an opponent’s targeting calculus by multiplying possible launch points, shrinking windows for engagement and forcing adversaries to spread scarce long-range munitions across a wider battlespace.
What ACE Demands: People, Processes and Technology
At its core, ACE requires profound changes to everyday airpower practices:
– Dispersal: Spread forces across multiple locations to complicate enemy targeting and create redundancy.
– Mobility: Move aircraft, personnel and sustainment assets quickly to exploit fleeting opportunities and reduce predictability.
– Agility: Empower lower-level commanders with authorities to act in time-sensitive situations so tempo, not bureaucracy, governs survival.
– Resilience: Harden operations against kinetic strikes, electronic attack and cyber intrusion while ensuring redundant sustainment pathways.
Putting these principles into practice is hard work. Aircraft must be prepared to fly from surfaces with limited support. Maintenance teams must execute more tasks with fewer facilities and thinner logistics tails. Commanders must accept operational risk by distributing forces across many sites instead of concentrating them in one defended hub.
Where ACE Is Being Tested
ACE is more than theory; it’s being exercised where the threat is real. Pacific Air Forces and U.S. Air Forces in Europe have run drills emphasizing short-notice basing, palletized maintenance kits, rapid runway repair and distributed command. Air Mobility Command has explored new ground-handling techniques and palletized logistics to speed turnarounds. Across the force, training pipelines now teach expeditionary skills — from rapid runway repair and fuel distribution to field sanitation — skills once reserved for specialized units.
Technological innovation is a double-edged sword for ACE. Modular maintenance kits, 3D printing, autonomous ground vehicles and untethered communications can enable operations in austere sites. The Air Force Research Laboratory and industry partners are trialing predictive maintenance, mobile maintenance shelters and autonomous logistics to shrink footprints and accelerate sortie generation. At the same time, reliance on networked tools increases cyber attack surfaces, and small, dispersed teams are inherently harder to defend physically.
Operational and Political Tradeoffs
Policymakers face clear tradeoffs. ACE reduces vulnerability but demands investment in training, prepositioned supplies, and authorities that liberate frontline leaders to act — investments that compete with modernization priorities like new aircraft and missile systems. There are diplomatic implications too: temporary basing on allied or partner territory requires negotiations over sovereignty, duration and risk sharing, and amplifies the need for interoperable logistics and legal frameworks among partners.
Logistics becomes the pivotal challenge. Distributed operations strain supply lines in novel ways: a small site with a damaged airframe needs timely parts and skilled labor. Command and control, deliberately devolved, invites miscommunication unless secure, resilient communications are maintained. In crises, the convenience of concentrating forces often tempts planners back to large forward bases because they are easier to support and command, undermining the goal of habitual dispersal.
Synergies and Vulnerabilities
ACE doesn’t stand alone; its most promising applications come when paired with complementary capabilities. Longer-range weapons that require fewer launches, integrated unmanned systems for ISR and logistics, and resilient space and airborne networks all amplify the value of dispersed basing. Conversely, superior adversary ISR and attrition of sustainment networks can blunt the advantages of dispersal. Dispersal complicates targeting, but it is not invulnerability.
Practically, distributed operations introduce new vulnerabilities: small teams are easier to isolate, logistics tails become more exposed, and network dependence multiplies potential cyber points of failure. Success will hinge on balancing lighter, faster sustainment with robust protection of data links, supply caches and maintenance capabilities.
The Stakes: Institutional Change or More Complexity?
If ACE succeeds, it will change the geometry of airpower. Commanders will generate fights from many small nodes rather than a few large hubs, forcing adversaries to expend more resources en masse and increasing operational uncertainty for opponents. If it fails, the Air Force risks creating a network of delicate outposts that are neither well defended nor easily sustained.
The central question for policymakers and airmen is straightforward: can the Air Force transform doctrine, logistics, maintenance and command culture so aircraft are truly prepared for the new reality? Success requires sustained funding, persistent training, legal and diplomatic frameworks for temporary basing with partners, and an institutional willingness to trade some short-term convenience for long-term survivability. Agile Combat Employment has already forced an overdue rethink: in an era of long-range precision, mobility and resilience are not optional — they are operational necessities.
