Are Kamikaze drones from Iran the ultimate threat to US aircraft carriers?

Modern warfare is evolving fast — most notably, and potentially, in the Gulf and the Strait of Hormuz.

Drones now form a central part of what's called "asymmetric war".

When two sides have unequal military power, instead of matching ships with ships, or missile with missile, the weaker side uses unconventional, lower-cost, high-impact tactics to offset the stronger side’s advantage.

Drones, generally known as unmanned aerial system (UAS), fit that model almost perfectly.

The types of drones used in warfare is increasing. The US military classifies UAS into five groups; Nato classifies them into three classes. 

Drones can disrupt shipping lanes, shutter airports, torch oil facilities, and damage critical infrastructure. They can force military ships into defensive posture.

The primary value of drones: low cost vs. high-value targets. For example, a $1,000–$20,000 drone can threaten:

That cost imbalance is classic asymmetric strategy.

In the Strait of Hormus, Iran's drone carriers like the Shahid Bagheri can unleash waves of Shahed-136 "loitering munitions" alongside Khalij Fars anti-ship ballistic missiles (ASBMs) and swarms of Peykaap fast attack boats.

They do. Iran's strategy pits inexpensive Shahed drones — carried by up to 60 per "carrier" — in massive swarms against a US carrier strike group like the USS Abrham Lincoln.

The carrier was recently targeted by a Shahed-139. A US F-35 fighter jet shot it down before it could get perilously close.

Traditional US defences like Aegis Combat System with SM-2 interceptors, CIWS Phalanx guns, and Rolling Airframe Missiles (RAM) could handle small numbers.

It's a serious challenge. In the Red Sea and Indian Ocean, for example, Houthi forces have launched hundreds of drones and anti-ship cruise missiles targeting commercial and military vessels.

Tackling every single one of them with 100% hit rate using conventional weapons would be pushing it: due to limited ammo of conventional weapons and high cost-per-shot — SM-2s cost millions of dollars each versus $1,000-$20,000 Iranian drones.

In an asymmetric war, electronic weapons are seen as increasingly relevant. They offer the potential to neutralise swarms without expending expensive interceptor missiles.

A 1,000-drone "swarm", if not more, poses a key threat to high-value assets protected by projectile-based weapons.

But new weapons have been developed to deal with such a threat, signifying a "quiet" shift towards electromagnetic warfare.

Yes — there are a number of options. Based on latest information by defence trade publication, these weapons of the future include:

A 2024 Defence Redefined report stated the US Navy planned to mount an HPM prototype on one of its combat vessels by this time (2026).

ODIN (Optical Dazzling Interdictor, Navy) is considered a lower-power "laser dazzler." Its primary function: to disrupt, blind, or disable the sensors of enemy drones, UAVs, and optical sensors, rather than destroying them through thermal destruction.

Currently installed on several Arleigh Burke-class destroyers, ODIN operates at the speed of light — literally 300 million metres per second.

Point it at a drone, pull the trigger, and it dies. No travel time, no lead calculations, no proximity fuses.

The best part about Odin: It runs on electricity. Carriers have nuclear reactors producing unlimited power, so Odin has infinite ammunition. The crew could take down 10,000 drones and never run dry.

HELIOS (High Energy Laser with Integrated Optical-dazzler and Surveillance): A 60-kilowatt (upgradable to 150 kW) high-energy weapon that can "hard-kill" (destroy) drones and small boats in addition to having dazzling capabilities.

It is integrated into the ship's combat system (Aegis) for faster target engagement. 

Raytheon (an RTX subsidiary) announced in December 2023 that it will design, build, and test high-power microwave antenna systems for the Navy to defeat airborne threats. The Navy has reported that METEOR project is managed by the Naval Surface Warfare Center Dahlgren Division.

It depends on who rules the sky, or the invisible spectrum. The current arms race is no longer just about who has the biggest boom.

It’ll be about who has the most energy, the smartest AI targeting, and the meanest electronic stack running at scale. It's beyond conventional battles — it's electronic warfare.

An electromagnetic hammer can knock these drones off. With unlimited ammo and high accuracy, numbers don't matter.

It's now become unthinkable how humanity could unplug this apocalyptic genie.

Drones blur the line between conventional war and proxy conflict.

In the shadows of modern battlefields, even limited drone attacks could unleash catastrophic ripple effects. They could choke supply chains, and ignite firestorms that dwarf conventional firepower.

So the drone nightmare isn't fading — it's evolving into humanity's deadliest epoch.

But now, we’re leveling up to full-on wizardy mode.

Turns out that war isn’t becoming louder, it’s becoming nerdier. The battlefield is ditching bullets and bombs for bandwidth and circuitry.

Whoever owns the spectrum owns the sky.

Welcome to the age where wars are won with watts, code, and control of the invisible.
