Spanish Navy Completes Hornet Block 1 Interceptor Drone Test Aboard Frigate SPS Santa María
The Spanish Navy has successfully tested the Hornet Block 1 interceptor drone aboard frigate SPS Santa María (F-81) using a containerized launcher installed on the flight deck. The test validated a counter-UAS air defense capability requiring no structural modifications to the vessel. The Hornet Block 1 features a range exceeding 75 km, a 1.5 kg warhead, and combines radar mid-course guidance with an autonomous electro-optical/infrared terminal seeker.

Highlights
- The Spanish Navy successfully tested the Hornet Block 1 interceptor drone aboard frigate SPS Santa María (F-81) using a containerized launcher on the flight deck, requiring zero structural modifications to the ship.
- The Hornet Block 1 has a maximum range exceeding 75 km and carries a 1.5 kg warhead, targeting subsonic aerial threats including small drones and UAV swarms.
- The system uses a dual-mode guidance architecture: radar mid-course guidance combined with an autonomous electro-optical/infrared (EO/IR) terminal seeker for final intercept.
- The containerized deployment concept significantly lowers the upgrade threshold for existing vessels, and is expected to attract attention from other NATO member navies amid rising drone swarm threats.
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.
