Indra Unveils Squall and Drizzle Counter-Drone Concepts

Spanish defense company Indra has unveiled two related concepts: Squall, a low-cost cruise missile intended for massed attacks, and Drizzle, a faster interceptor designed to address the growing counter-drone problem.

Two systems for an increasingly crowded air picture

Aviation Week reports that Squall is being designed for ground and maritime launch, with a claimed range of about 300 kilometers and a low-level flight profile. Indra says the concept would use multiple guidance and navigation methods to remain effective in the presence of jamming and spoofing.

The company also presented Drizzle as a drone interceptor with a speed of roughly 250 miles per hour and a range of about 50 miles, with a longer reach possible when released from a high-flying mothership. These are company-described concepts, so performance figures should be treated as targets rather than independently verified operational results.

Why affordability is part of the design

Modern air defense has to manage an uncomfortable cost exchange. A defender may spend an expensive missile against a relatively cheap uncrewed target, especially when an attacker uses decoys or launches many aircraft at once. Low-cost offensive weapons and lower-cost interceptors are both attempts to make that arithmetic less one-sided.

The hard engineering problem is not just building a fast airframe. The system must find the right target, resist interference, receive useful track data, and complete an engagement without consuming more resources than the threat justifies. That pushes the design toward networked sensors, modular seekers, and repeatable manufacturing.

What to watch next

The important next milestones would be prototype construction, flight testing, seeker demonstrations, and evidence of integration with existing command-and-control networks. European buyers are also likely to ask how the systems fit into layered defense rather than operating as stand-alone weapons.

For the broader drone industry, Indra's announcement reinforces that counter-UAS requirements are expanding beyond small jammers and guns. Future systems will combine detection, electronic effects, kinetic interceptors, and affordable command software, with the right mix changing according to the mission and threat density.

The counter-drone market is becoming a systems market

Squall and Drizzle show two sides of the same trend: European defense planners want more affordable mass, while defenders need faster and cheaper ways to handle massed uncrewed threats. The concepts will be judged by testing and production, not by the unveiling alone.
