US Military Seeks Cheaper Drones to Counter Iran's Air Defenses

The US military has lost dozens of Reaper drones collectively worth more than $1 billion while carrying out surveillance and attack missions over Iran. The Pentagon is now seeking large numbers of cheaper drones that can perform such missions despite the expectation that many will be lost in combat. The Defense Innovation Unit's notice described the US military's current reliance on drones and crewed aircraft, each costing more than $30 million, as being "unsustainable against adversaries utilizing layered defenses enabled by increasingly low-cost antiaircraft capabilities." It envisions deploying more "cost-effective" drones to "overwhelm enemy air defenses even while experiencing numerous [drone] losses." Ukraine's military has been demonstrating a similar approach with its long- and mid-range strike campaign against Russian supply lines, oil refineries, and various energy or industrial targets within Russia or occupied Ukraine.

The Ukrainian campaign has been overwhelming Russia's overstretched air defense capabilities by launching hundreds of relatively inexpensive drones and missiles on a daily basis to attack targets far behind the frontlines, while continuing to damage or destroy Russia's most sophisticated air defense systems. This strategy allows for a saturation of enemy air defenses, making it difficult for them to respond effectively to the sheer volume of incoming threats. The US military aims to adopt a similar tactic, utilizing cheaper drones to saturate and overwhelm Iran's air defenses.

Why this matters: The US military's pursuit of cheaper drones reflects a broader shift in its approach to modern warfare, where the increasing availability of affordable, capable unmanned systems is redefining the cost-benefit analysis of military operations. For developers and businesses, this trend presents opportunities to create innovative, cost-effective solutions that can withstand the rigors of combat. As the US military moves to deploy these drones, it will be crucial to balance the need for affordability with the requirements for reliability, range, and payload capacity.

The success of this strategy will also depend on the ability to integrate these cheaper drones into existing command and control structures, and to develop effective tactics for maximizing their impact while minimizing losses. Ultimately, the outcome will have significant implications for the future of military aviation and the role of drones in modern warfare.
