What Is the Seaspray Radar? Leonardo’s Maritime-Surveillance AESA Radar Family
Seaspray is Leonardo’s lightweight AESA radar family for maritime patrol and surveillance aircraft and helicopters. Known for high-resolution detection of small surface targets and periscopes, it equips platforms from UAVs to coast-guard aircraft — and represents Leonardo’s strong electronics footprint in the U.S. market.

What Seaspray Is
Seaspray is a radar family that scans the sea surface with AESA technology, specialised in detecting small, low-profile targets — smuggler boats, periscopes, life rafts. With high-resolution imaging modes (SAR/ISAR), it does more than detect a target; it builds a radar image to help classify it. Its light, compact build lets it integrate even onto limited-payload platforms like UAVs.

Mission Profiles
Seaspray is used for maritime patrol, border and coast-guard security, support to anti-submarine warfare, search-and-rescue, and detection of smuggling and illegal crossings. As the core sensor of the AW159 Wildcat helicopter, it moves beyond a surveillance radar to become a weapon-system engagement sensor.
Leonardo’s Role
Seaspray is a radar family developed entirely in-house by Leonardo. Its selection on various U.S. and allied maritime-surveillance platforms shows that Leonardo holds a strong position not only in Europe but in the U.S. — the world’s most competitive defence-electronics market.

Competing Systems
| System | Maker | Country | Difference |
|---|---|---|---|
| Osprey / SeaVue | Raytheon | USA | American maritime-surveillance rival |
| Searchmaster | Thales | France | European maritime radar rival |
| AESA maritime radars | Aselsan | Turkey | Turkish indigenous equivalents |
Turkey Relationship
Turkey is moving to meet its maritime-surveillance radar needs with indigenous Aselsan solutions. Domestic AESA maritime radars developed for Turkish UAVs and maritime-patrol platforms cover the missions Seaspray performs. The Seaspray is therefore seen in Turkey less as a direct procurement option and more as an equivalent that may compete with Turkish systems in export markets, particularly in the UAV surveillance-radar segment.
Strengths and Weaknesses
Strengths: a light/compact build, superiority in small-target detection, broad platform compatibility and a strong U.S. market position. Weaknesses: intensifying UAV-radar competition, rising indigenous alternatives, and more limited range than large maritime-search radars.
