Spanish Navy Completes Hornet Block 1 Interceptor Drone Test Aboard Frigate SPS Santa María

According to a report by Naval News, the Spanish Navy has conducted a successful test launch of the Hornet Block 1 interceptor drone aboard frigate SPS Santa María (hull number F-81), as part of a demonstration program for containerized shipborne air defense systems.

Containerized Launcher Requires No Structural Modifications

For this test, the Hornet Block 1 launch system was installed in containerized form on the frigate's flight deck, successfully validating the integration of a counter-UAS air defense capability without any modifications to the warship's core structure. This flexible deployment concept significantly lowers the threshold and cost for upgrading existing vessels.

Hornet Block 1 System Specifications

The Hornet Block 1 is an interceptor drone designed to engage subsonic aerial threats, with primary targets including small drones and coordinated UAV swarms. The guidance system uses a dual-mode design:

• Mid-course guidance: Radar-guided mid-course corrections
• Terminal guidance: Autonomous electro-optical (EO)/infrared (IR) seeker for independent target tracking during the final intercept phase

According to manufacturer-published technical data, the system's key specifications are as follows:

Specification	Data
Maximum Range	Over 75 km
Warhead Weight	1.5 kg
Target Types	Subsonic aerial threats, small drones, UAV swarms

Modular Air Defense Capability Draws NATO Attention

As drone swarm attack tactics become increasingly prevalent in modern conflicts, navies worldwide are facing growing demand for rapidly deployable and reliable counter-UAS systems. The Spanish Navy's test demonstrates a viable pathway for equipping active-service vessels with new air defense capabilities at minimal retrofit cost — a development expected to attract significant interest from other NATO member states.
