U.S. Fires JAGM Missiles from Saildrone Surveyor USV to Expand Distributed Firepower at Sea.

Lockheed Martin and Saildrone launched two JAGM missiles from a Surveyor-class unmanned surface vessel during RIMPAC 2026, demonstrating that the platform can receive external targeting data and execute a remote engagement. The test advances the US Navy’s effort to distribute sensing and firepower across unmanned vessels while reducing reliance on crewed combatants for forward presence.

Conducted near Hawaii and announced on August 20, 2026, the trial paired the 20 m Surveyor with a dual AGM-179 JAGM launcher and the US Navy’s Adjunct Remote Engagement System. Operating with the USS Theodore Roosevelt Carrier Strike Group, the vessel engaged a surrogate high-speed surface craft after receiving targeting information from the wider force. The Surveyor can remain deployed for up to 100 days between maintenance stops, cruises at about 6 knots in mapping operations, and provides 3 kW of continuous payload power. Follow-on work is expected to move toward the larger Spectre-class USV, including integration of heavier containerized systems such as the Mk 70 launcher.

The Surveyor is primarily an endurance platform rather than a high-speed vessel. Measuring 20 m in length with a 3.6 m draft, it combines an 80 hp diesel engine with auxiliary propulsion provided by Saildrone’s wing system. Its mapping speed reaches 6 knots, while its logistical endurance can extend to 100 days between maintenance stops. These figures are also reflected in missions already completed by the class. One Surveyor carried out a 4,000-nautical-mile round trip to reach an operating area in the Aleutians, while another autonomous mission between San Francisco and Honolulu covered 2,250 nautical miles in 28 days. Its military value therefore lies less in speed than in the ability to keep a sensor, or now an effector, deployed thousands of nautical miles from its point of departure, with 3 kW of continuous payload power and up to 6 kW at peak demand.

In a communication published on August 20, 2026, Lockheed Martin stated that this endurance was combined during RIMPAC with a dual AGM-179 JAGM launcher and the US Navy’s ARES fire control system. The missile uses a dual-mode seeker combining semi-active laser guidance and millimeter-wave radar, allowing it to engage moving targets in a maritime environment without requiring the Surveyor itself to provide the entire detection and designation chain. JAGM’s range of around 8 km remains short by naval combat standards, but this was not the main focus of the trial. The platform received targeting data generated by other assets within the USS Theodore Roosevelt Carrier Strike Group and converted that information into a kinetic effect. The test therefore focused as much on networked engagement as on the physical integration of the missile.

The tactical role becomes clearer when placed in the context of missions already considered for US unmanned surface vessels. A Surveyor positioned at the entrance to a strait, along an approach route to a carrier strike group or near an amphibious landing area could remain on station for several weeks while combining passive surveillance with the ability to engage fast surface craft. During RIMPAC, this concept was illustrated by the engagement of a target representing a high-speed surface vessel. In a scenario comparable to those seen in the Red Sea since 2023, where Western warships have had to commit surface-to-air missiles and flight hours against drones and surface threats, an armed USV could handle some of the less complex contacts at a distance from the main combatant. Its speed of 6 knots, however, rules out a rapid interception role. The Surveyor is better understood as a pre-positioned surveillance and firing node than as a surface interceptor, and its effectiveness depends directly on the communications and targeting network to which it is connected.

This logic also explains the planned move toward the Spectre, a 52 m platform rated at 27 knots in operational configuration, with a range of more than 8,000 nautical miles at 12 knots and the capacity to carry multiple 20 or 40 ft containers. Saildrone has identified the Lockheed Martin Mk 70 launcher and towed acoustic systems among the planned integrations. The difference from the Surveyor is substantial. While the first demonstrator carries two short-range JAGMs, a Spectre fitted with an Mk 70 could potentially accommodate missiles from the Standard or Tomahawk families depending on the configuration selected by the US Navy. The concept would therefore move beyond local area defense and toward distributing part of a naval force’s missile inventory across unmanned platforms operating over hundreds or thousands of nautical miles.

The geopolitical implications are particularly relevant in the western Pacific, where US forces face the growing density of Chinese detection and strike systems around Taiwan and the first island chain. USVs able to travel several thousand nautical miles and remain on station for extended periods could allow the US Navy to increase the number of sensing points and, eventually, launch cells without routinely exposing an Arleigh Burke-class destroyer or another crewed combatant. This approach responds directly to the challenge posed by the size of the Chinese fleet and by the concentration of sensors and missiles on a limited number of large US platforms. The RIMPAC firing also reflects a broader trend already seen in combat in the Black Sea, where Ukraine has gradually developed its USVs from explosive attack craft into reusable systems equipped with rockets and air-to-air missiles. That experience shows how relatively light unmanned naval platforms can expand beyond reconnaissance or direct attack roles and force an opposing fleet to adapt its surveillance, protection and interception measures.
