Proliferation of unmanned systems in modern warfare has popularized the notion that traditional platforms have reached the end of their operational relevance. Particularly, the Russia-Ukraine war has deepened the perception that small, agile, and inexpensive drones have rendered manned platforms in land, air, and sea domain obsolete.

This argument gains credibility while assessing drones’ performance against manned armored vehicles which are now routinely labelled as outdated systems against drone-enabled precision strikes. Yet, what is often depicted in the media is only one side of the coin. Drones often fail to find targets, are intercepted, or manage to hit their target, thus not achieving intended results. Despite proliferation of first-person view (FPV) drones, armored vehicles continue to play a vital role in maneuver warfare and protected mobility. Modern armor strategies have evolved to include combined arms and dispersion rather than mass for increasing survivability and combat efficiency. In the Russia-Ukraine war, several rudimentary measures like installation of cope cages atop turrets, have been implemented by both militaries to enhance the survivability rate of tanks against kamikaze drones. Vehicle mounted jammers have also shown promising results. Defensive technologies, like active protection systems (APS) and electronic countermeasures (ECM), have proven their efficiency against FPV drones. Thus, it can be argued that drones have not turned armored vehicles obsolete; they have forced them to evolve into more refined systems.

Similarly, in the aerial domain, many analysts perceive unmanned aerial systems (UAS) as cost effective alternative vis-à-vis manned aircraft. Yes, UASs have shown impressive evolution. From dropping laser-guided bombs (LGBs) to firing cruise missiles, air-to-air missiles, torpedo, and even smaller drones, drones have come a long way in changing warfare. Increasingly, drones have pushed manned aircraft aside as a more efficient option for operational engagement. In Nagorno-Karabakh conflict, Azerbaijan innovatively employed aerial drones to expose Armenian air-defenses’ positions making them vulnerable to subsequent Azerbaijan’s targeted strikes. This unique use of drones as a crucial component of SEAD/DEAD (Suppression & Destruction of Enemy Air Defenses) kill chain marked a watershed moment in modern warfare.

However, the inherent limitations of drones are obvious too. UASs are more susceptibility to electronic warfare (EW) disruption and have unproven records in complex battlespace with dynamics rules of engagement (ROEs). Claims that unmanned systems will soon replace fighter jets overlook the enduring advantages of human decision-making in contested and escalation-sensitive environments. Manned aircraft provide operational flexibility and command judgment that are yet to be replicated through automation alone. The developmental trajectory suggests that instead of perceiving UAVs as one-one-one substitute for piloted aircraft, the future lies in Manned-Unmanned Teaming (MUM-T) where manned aircraft will serve as command nodes while accompanied unmanned systems will provide mass, persistence, and attainability.

In the naval domain, the successfully employment of kamikaze surface and aerial drones by Ukraine in the Black Sea conflict is now frequently cited as an indicator that large surface combatants will soon turn into relics of past. Besides sinking multiple Russian warships in the Black Sea, Ukraine has even damaged a Russian Kilo class submarine stationed at Novorossiysk harbor using an underwater suicide drone. The Russian Black Sea Fleet, despite having overwhelming superiority over Ukrainian counterpart, has failed to establish sea-control in the Black Sea primarily due to remarkable performance of Ukrainian naval drones.

Similarly, in the Red Sea crisis, the Houthis’ rudimentary drones have challenged the operational persistence of Western naval powers. Kamikaze drones have compelled American, British, French, and German warships to deplete expensive air-defense missiles, which in some cases resulted in pre-mature withdrawal. Close-in Weapon Systems (CIWS) is usually considered a potent point of defense against all types of aerial threats in the maritime domain. However, both gun-based and missile-based CIWS have limited magazine capacity and engagement range. This suggests that against a more capable adversary, drone swarms can saturate warships’ defenses and can cause mission-kill by damaging critical instruments onboard, rendering them inoperable for extended time duration.

Although naval drones have added an additional layer of threat for warships, they do not, in themselves, render them obsolete. Novel defensive capabilities for countering drone threats are already in the developmental phase. Few systems have been deployed and evaluated in real combat. For example, on 03 March 2024, an Italian Andrea Doria class destroyer shot down an incoming kamikaze drone threat in Red Sea using DART projectiles fired from 76mm deck gun, a move far more economically feasible than air-to-surface missile. Similarly, high-energy lasers (HELs) onboard warships are being tested for countering drones. Besides kinetic defensive application, soft-kill measures such as jammers and decoy systems are also emerging as critical components of warships defensive suite.

In addition, the Black Sea and the Red Sea are enclosed bodies of water, offering limited operational space for naval forces and providing tactical advantage to drone-based asymmetric tactics. In blue waters, however, the effectiveness of such drones would diminish considerably. In open seas, it is unlikely that even mass formations of drones would be able to penetrate modern naval armadas. Although suicide drones can be used in formation with cruise and ballistic missiles to outclass adversary air-defenses, but repeating such a feat against time-sensitive and well protected high-value naval ships would be a very challenging undertaking. Thus, it can be argued that sea drones can be employed as enablers or force-multipliers in conjunction with other systems, but not as decisive instruments of naval warfare.

The future of warfare will not be defined by the triumph of drones over manned platforms. Today, drones have turned into a potent tool of warfare and are also an integral part of the kill-chain of modern militaries around the globe. However, limitations cannot be ignored. In practice, drones work less as independent war-winning weapons but are enablers and force-multipliers. In the age of viral narratives and simplified conclusions, misperceptions regarding military technologies are bound to persist. No single military system determines the outcome of war, and no single innovation renders all others irrelevant. Military power is cumulative and contextual.

The ongoing conflict involving Iran, the United States, and Israel has produced one of the most significant case studies in the evolution of contemporary warfare. Iran, a state that lacks a competitive air force and possesses limited naval power, has demonstrated that ballistic missiles, cruise missiles, and unmanned aerial systems can offset some conventional disadvantages and impose serious costs on technologically superior adversaries. This development is not confined to the battlefield. It represents a doctrinal shift with lasting implications for American deterrence strategy, allied defense planning, and the long-term viability of current U.S. force structures. Understanding what Iran has and has not achieved is essential for making sound policy going forward.

The Cost-Exchange Problem 

At the operational level, Iran’s most consequential contribution has been exposing a structural vulnerability in layered air defense: the cost-exchange dilemma. Systems such as Patriot, THAAD, and Iron Dome were engineered to intercept high-value ballistic and cruise missile threats. When deployed against coordinated waves of low-cost drones and short-range missiles, these systems are forced to expend interceptors valued at hundreds of thousands or millions of dollars per shot against threats that cost a fraction of that amount. The arithmetic is unsustainable at scale. As analysts at the Center for Strategic and International Studies have noted, saturation attacks can exhaust defensive inventories faster than replenishment is possible, creating windows of vulnerability that adversaries are quick to exploit. For the United States, this is not merely a technical problem, it is a strategic one that requires urgent attention in both procurement and doctrine.

The development of the Golden Dome missile defense architecture and expanded investment in directed energy and electronic warfare systems reflect growing official awareness that current interception models are not cost-competitive. These are necessary steps. However, technology alone cannot resolve a dilemma that is fundamentally about the economics of offense versus defense. Adversaries will adapt their tactics faster than procurement cycles can respond unless the U.S. also changes the strategic logic driving their calculations.

Attrition Without Decision: The Limits of the Iranian Model

The Iranian approach has imposed genuine costs on its adversaries, but it has not produced decisive military outcomes. This distinction is critical. Iran’s missile and drone campaigns have disrupted logistics, strained defensive inventories, and created operational uncertainty. They have not, however, defeated U.S. or Israeli military power, seized or held territory, or forced a negotiated settlement on Iranian terms. The model is one of strategic attrition, not strategic victory. Survivability and persistence are not equivalent to effectiveness, and the broader narrative of a drone revolution rendering conventional military power obsolete requires significant qualification.

The claim that air superiority is no longer a necessary condition for strategic effectiveness also warrants scrutiny. Air superiority remains essential for intelligence, surveillance, and reconnaissance; for close air support of ground operations; and for denying adversaries freedom of movement. What Iran’s campaign demonstrates is that a state without air superiority can still impose costs and delay adversary operations—not that air power has been rendered irrelevant. The bar for what air superiority can guarantee has been raised. Its strategic value, however, has not disappeared. Policymakers and analysts should resist the temptation to draw sweeping conclusions from a conflict that remains ongoing and whose full operational record is still emerging.

Implications for American Deterrence

The proliferation of precision strike capabilities across state and non-state actors undermines the assumption that technological overmatch alone is sufficient to deter conflict. When adversaries can field asymmetric capabilities that challenge U.S. and allied defenses at an acceptable cost to themselves, deterrence by denial becomes increasingly difficult to guarantee. The U.S. must prioritize cost-effective interception technologies, particularly directed energy weapons, that can neutralize mass drone and missile attacks without depleting high-value interceptor stocks. This is a resource allocation problem as much as it is an engineering one, and it demands serious engagement at the budgetary and strategic planning levels.

The Iranian model is also exportable, and this may prove to be its most consequential long-term dimension. States with limited defense budgets that are aligned with China or Russia can observe the operational lessons from this conflict and apply them in their own regional contexts. The proliferation of domestically produced or externally transferred missile and drone capabilities across the Middle East, South Asia, and the Indo-Pacific represents a compounding deterrence challenge. American extended deterrence commitments to allies in these regions will become harder to sustain if the cost-exchange problem is not structurally resolved. As Defense News reported, the proliferation of drone technology is already forcing militaries worldwide to reconsider their approach to air and missile defense.

There is also a crisis stability dimension that deserves serious attention. Rapid, sustained missile and drone strikes compress decision-making timelines and increase pressure for early, and potentially disproportionate, responses. In a multipolar environment where multiple actors possess similar strike capabilities, the risk of miscalculation is elevated. The U.S. should pursue updated arms control frameworks and diplomatic mechanisms to manage the proliferation of these systems alongside its technical and procurement investments. Deterrence cannot be reduced to hardware alone.

Conclusion

Iran’s missile and drone campaign has not rewritten the principles of warfare, but it has exposed critical assumptions underpinning American deterrence in ways that cannot be ignored. Distributed, low-cost, high-impact systems are now accessible to a wider range of actors and the gap between offensive capability and defensive cost is widening. The United States requires a

deterrence posture that integrates cost-effective defense, credible offensive options, active non-proliferation diplomacy, and sustained alliance management. Meeting this challenge demands strategic adaptation across doctrine, procurement, and diplomacy, not simply an incremental increase in interceptor production.
