The future of conflict in the Western Pacific will hinge on sustaining firepower over vast distances with finite magazines and vulnerable logistics. The Russia‑Ukraine war and much of history show that victory has never relied on a small inventory of exquisite, high‑cost weapons.1 Instead, success increasingly rests on combining massed, affordable drones with a more limited stock of precision‑guided munitions—a munitions‑centric high–low mix. To deter and, if necessary, defeat aggression, the U.S. should build a mix of long‑range, payload-modular drones. This approach is about designing an economically favorable, attrition‑resilient strike architecture that forces an adversary into unfavorable cost‑exchange ratios.
Originally a Cold War concept that paired high‑ and low‑end manned platforms against the Soviet Union, the high–low mix has re-emerged in a new form centered on munitions rather than platforms. A munitions‑centric high–low mix forces adversaries to choose between defending against slow, numerous drones or conserving interceptors for higher‑end threats, thereby creating gaps in their air defenses.2 In a theater defined by extended supply lines and constrained magazines, such a mix will be essential to sustaining combat power and imposing escalating costs on the People’s Liberation Army.
Lessons from Ukraine
At the onset of the war, Russia relied heavily on conventional combined arms but quickly transitioned—much as Ukraine did earlier—to a new toolset of drones to contest the land, sea, and air domains. Two lessons stand out for U.S. planners preparing for a conflict in the Pacific.
First, Ukraine has effectively combined maritime drones with traditional missiles and employed “mothership” drones to extend range at sea. The integration of sea drones with missile air defense systems significantly degraded Russia’s presence in the Black Sea by simultaneously threatening ships and their helicopter escorts.3, 4 The operations in the Black Sea demonstrate how relatively inexpensive unmanned systems, when integrated with existing traditional weapons, can constrain an adversary’s freedom of action and impose enduring costs.
Second, and most importantly, both sides utilized one‑way attack drones in conjunction with precision munitions to saturate and exhaust air defenses. Russia pummeled Ukraine with long-range drones, depleting valuable interceptors and straining Ukrainian air defense.5, 6 This pattern would likely repeat in any high‑intensity air and maritime campaign in the Western Pacific. Therefore, the grinding stalemate in Ukraine is less a model to emulate than a warning of the nature of future war.
Requirements for a Pacific High-Low Mix
In the Pacific, drones will require operational ranges approaching 2,000 nautical miles to be meaningful, with a minimum of 100 nautical miles for tactical systems if basing rights near key terrain can be established. Longer‑range systems provide greater operational leverage but will substantially increase costs and reduce temporal fires volume (the weight of effects delivered per unit of time). With these facts in mind, three key requirements emerge.
First, missiles and drones must be deployable from land, sea, and air. Cross‑domain employment or launch-system interchangeability reduces platform-specific dependencies and mitigates the need for extreme‑range systems that may arise in a contested single domain. Interchangeability will streamline supply chains and logistics, as a munition can be fired from multiple platforms with minimal modification, usually with a simple software update.7 The Harpoon anti-ship missile illustrates this principle by being employable from surface, subsurface, and airborne platforms. A surface launch from a ship or ground launcher achieves greater than 70 nautical miles. From an aircraft, the effective range is boosted by the aircraft’s range, often over 500 nautical miles, and can be extended via aerial refueling.8 The same logic should guide the integration of drones against integrated air defense systems.
The risk posed by Chinese long‑range ballistic missiles will likely push the effective denial boundary for surface forces greater than 1,000 nautical miles.9 The U.S. faces a shortfall in strategic sealift capacity, and any Pacific campaign will expose sustainment ships and aircraft to long‑range strike.10 To reduce risk, sustainment forces may be pushed even further from the fight. To sustain combat power, mass must be delivered efficiently and quickly at acceptable risk levels. Taken together, these constraints imply that the U.S requires families of drones binned by range: shorter‑range systems that exploit forward bases near key terrain and longer‑range systems that can operate from well outside threat weapons’ reach.
Because of the ranges involved, purpose‑built drones for the Pacific theater will be more expensive than those used in Europe or the Middle East. In Ukraine, Shahed or Geran drones, with ranges of up to roughly 1,600 nautical miles, provide Russia with coverage of the entire battlespace with multiple routing options, offering significant operational flexibility at relatively low cost.11 By comparison, a similar drone launched from Guam would be on a straight-line attack, approaching its maximum range.
Long-range drones typically use small reciprocating engines and thus avoid some of the solid‑rocket‑motor supply‑chain constraints that affect missiles, as well as the technical complexity associated with gas turbines.12 LUCAS, a new one‑way attack drone reportedly based on the Iranian Shahed‑136, has an estimated range of approximately 1,500 nautical miles and may be among the most promising near‑term options.13 Other candidates include systems such as Altius and Barracuda, with ranges from roughly 100 to over 500 nautical miles.14, 15, 16 While the exact design line between drones and cruise missiles may be blurred, their ability to carry multiple payloads and operate autonomously places them conceptually within the drone portion of the high–low mix. Forcing an adversary to divert resources or believe that one effort is more important than another can have far-reaching strategic effects.
For example, expending large numbers of expensive interceptors against relatively cheap drones increases an adversary’s defensive missile expenditures and creates temporary windows when their air defenses are saturated. During those windows, U.S. forces can employ exquisite missiles against high‑value targets at lower risk, as already seen in Ukraine.17 This tactic increases the effectiveness of individual exquisite munitions and, over time, reduces the cost per target of the combined effect. It also forces adversaries into persistently unfavorable spending patterns and increasing long‑term operational costs. This may potentially force a shift in money or production away from other key weapon systems to fill gaps in air defenses.
For example, the conflict between Israel and Iran following the October 7th attacks. Across three major engagements in October 2024, April 2025, and June 2025, Iran employed more than 1,000 drones and 500 missiles.18 By the end of the exchange, reports indicated that Israel was running critically low on interceptors, and the U.S. had significant shortages of THAAD missiles, while Iran was assessed to still have thousands of missiles and drones remaining in its inventory.19, 20
Moreover, Iranian attacks became increasingly effective over time. By the final round of strikes, more than 60 missiles were impacting Israeli territory—over twice the number that got through in the initial October attack.21 The most consequential aspect of this campaign was not the tactical success but the operational effects Iran achieved. The time and cost required for Israel to repair infrastructure and replenish high-end interceptors are many times greater than the expense of the relatively low-cost, improvised missiles and drones that Iran employed. Iran consumed valuable maintenance hours and sortie-generation capacity that would otherwise support offensive strike missions. If Iran possessed a more capable air force, this kind of coercive, resource‑draining approach could be decisive in shifting the operational balance in its favor by steadily degrading Israel’s ability to generate credible offensive power.
The core operational lesson is that a sustained high–low mix can impose continuous defensive burdens, consume precious economic capital, and erode an opponent’s ability to sustain offensive operations. For the Indo‑Pacific, U.S. and allied forces must be prepared to wage a drawn‑out contest in which the key question is not who fields the most exquisite platforms on day one, but who can afford to keep firing on day one hundred.
The U.S. fields broad capabilities but limited depth in its weapons inventory. A perfect example is the U.S. pursuit of hypersonic weapons since the early 2000s, with little advancement in programs’ operational numbers despite Russia and China likely now fielding operational systems at scale.22 The simple fact regarding U.S. weapons is this: specialized but less scalable than many of their potential adversaries. That creates limits and risks for the platforms that provide the “punch” in potential conflict. To remain competitive, U.S. planners should prioritize modular, cross‑domain-capable drone and missile platforms that can be field-modified and mass‑produced, with an emphasis on range, speed, and flexibility.
Sustainment and Modularity for the High-Low Mix
Modern war is a voracious consumer of munitions. Therefore, the ability to conduct sustainment at scale is critical. Containerization for transport and employment should be the baseline requirement for any drone adopted into U.S. military service. Standardized launch containers can be dispersed on ships, barges, trucks, and austere airstrips across the theater. This distribution complicates adversary targeting, reduces the risk of preemptive strikes on centralized depots, and eases movement into the theater, potentially allowing contracted non-traditional shipping to carry containerized drones and freeing dedicated military sealift for other cargo. The CONSOL concept, in which fuel from civilian tankers is delivered to U.S. Navy oilers and warships, could serve as a model for sustaining containerized drones with minor modifications.23 In practice, this would allow containerized drones to move through commercial and military logistics channels much like fuel or standard cargo, enabling surge munitions flows into the theater without overexposing scarce sealift and major logistics hubs.
The final key enabler is the use of modular drone payloads. A common airframe that can be configured as a jammer, decoy, sensor, or one‑way attack munition allows commanders to tailor each salvo to the mission. Existing systems already demonstrate this potential, carrying payloads ranging from electronic‑attack packages to surveillance sensors.24, 25, 26, 27 Modularity achieves two ends. First, it reduces sustainment risk by minimizing the number of unique systems or components that must be transported into the theater. Second, it increases the probability of a salvo’s success by integrating jammers, decoys, and attack drones into a single, coordinated attack. Determining the optimal drone-to-missile mix requires experimentation to identify force packages that achieve the desired outcomes at minimal cost. Modularity also improves cost‑exchange performance by allowing commanders to reconfigure existing airframes for new tasks rather than fielding separate, specialized systems for each mission set.
Drone-from-Drone and Mothership Concepts
Recent testing of a Switchblade 600 one‑way attack drone launched from a larger MQ‑9A Reaper, the same drones synonymous with the War on Terror, illustrates how drone‑from‑drone concepts can extend the reach and responsiveness of unmanned systems.28 Because the MQ‑9 has roughly twice the speed and greater range than a LUCAS‑type drone, this approach could increase engagement options and compress timelines.29
A more resilient system would include theater‑range modular drones and a dedicated mothership, such as the MQ-9 or other long-range drone, which would carry shorter‑range attack drones. Modular theater drones conduct missions requiring greater payload and power, such as jamming. This nested architecture reduces dependence on manned, high‑value platforms and provides additional means to generate the force mass required to penetrate layered defenses.
Mothership concepts introduce additional command‑and‑control and deconfliction challenges that will require rigorous experimentation and wargaming before adoption at scale. Yet if implemented effectively, they would confront adversary commanders with overlapping dilemmas: theater‑range modular drones launched from ground, sea, or air; shorter‑range munitions deployed from motherships; and exquisite missiles capable of rapid, penetrating strikes. Together, these elements complicate air defense planning and increase the likelihood that some portion of each salvo reaches its targets. Crucially, the U.S. must not lose sight of the fact that China is also experimenting in this field. To maintain its edge, the U.S. must begin rapid live‑fire experimentation to formalize doctrine, create feedback loops for software, and refine command‑and‑control architectures for the inevitable drone‑on‑drone fights.
Conclusion
A future war in the Western Pacific will not be decided by which side fields the most exquisite platforms on the opening day of combat, but by which side can afford to keep firing on day one hundred. The U.S. is currently organized around a force-and-munitions paradigm that assumes short, decisive campaigns that do not exist in reality. Against a peer with a large, industrialized economy and an asymmetric approach designed to circumvent U.S. short-range precision strike, the result is likely paralysis if not outright defeat.
This is not a call for more technology for its own sake, but for different economics in how we design and employ firepower. Containerized, cross‑domain‑launchable drones; modular payloads that can be rapidly reconfigured between jamming, sensing, decoy, and strike; and drone‑from‑drone or mothership concepts that multiply the reach of each sortie—all are tools for building a strike architecture that can absorb attrition and generate effects at scale.
If the U.S. fails to make this shift, it risks entering a Pacific conflict on China’s terms: overextended logistics, shallow magazines, and a force trapped in a defensive, interceptor-driven pattern of expenditure. But if senior leaders move now and implement the suggested changes, the balance changes.
The choice, then, is straightforward. The U.S. can continue to organize its Pacific posture around a shrinking set of exquisite platforms and munitions and hope they survive long enough to matter. Or it can accept that the defining contest of a Western Pacific war will be industrial and economic output at scale. The window to make that choice is closing fast.
