Shipboard laser weapons do not simply point at a moving target and fire. A ship’s sensors first build a target track; an electro-optical director then acquires and holds the target in view; the system applies the effect it was designed for; and sensors help assess what happened. Public Navy reports document parts of this chain and several specific demonstrations, but do not publish universal accuracy, dwell-time, range, or weather limits.
How does a shipboard laser track a moving target?
The engagement is a sequence of cueing, optical tracking, authorization, and assessment. A laser director has to keep the target in a usable line of sight long enough to produce the intended effect. The Navy’s public descriptions identify these broad tasks, but do not disclose a single tracking method or set of performance figures that applies to every system.

1. Detect the threat and build a track
A ship’s combat system or another sensor detects a possible threat and estimates where it is and how it is moving. The resulting track can cue a laser director, rather than requiring its optics to search the entire scene unaided. In a 2014 account of LaWS development, the Office of Naval Research (ONR) said tracks from the Phalanx Close-In Weapon System could be handed to LaWS’s targeting and tracking system. The report established that this handoff was demonstrated; it did not describe the data format or handoff logic.
2. Acquire the target optically and lock
The optical director points toward the cued target, uses its imaging or viewing equipment to acquire it, and maintains a more precise track. NAVSEA’s May 2026 account of training for the Optical Dazzling Interdictor, Navy (ODIN), specifically describes operators learning to track and lock on targets using the system’s console. It mentions cameras and a telescope, but that description is not a specification for all naval lasers.

- Versatile Use — Perfect for classroom teaching, business presentations, and professional meetings.
3. Select and apply the intended effect
“Engage” does not always mean burn through a target. ONR described LaWS as capable of effects ranging from disabling to complete destruction. NAVSEA describes ODIN as a dazzler designed to blind unmanned aerial system sensors. These are distinct missions: a system intended to interfere with a sensor should not be described as though every engagement destroys the airframe.
4. Keep aim and assess the result
Once the system is firing, the director must continue to track as the target moves and the ship may move as well. Public accounts confirm tracking and locking tasks and describe successful tests, but do not give the dwell time, stabilization accuracy, or tracking-error figures needed to quantify that challenge. ONR’s 2022 report on the Layered Laser Defense (LLD) also describes a high-resolution telescope used to track inbound air threats, support combat identification, and conduct battle-damage assessment.
What have Navy reports demonstrated?
The demonstrations below show that moving targets have been part of reported testing, but they differ in system, setting, date, and purpose. They should not be read as proof of a universal capability against every threat.

| System and report | What the report describes | Scope to keep in mind |
|---|---|---|
| LaWS, ONR, 2014 | Phalanx target tracks handed to LaWS’s targeting and tracking system; an operator used a laser weapon control console. | A reported development demonstration. The account does not publish handoff logic or quantitative tracking performance. |
| LaWS aboard USS Ponce, NAVSEA | Trials included engagements against targets on a speeding small boat, a ScanEagle unmanned aerial vehicle, and other moving targets at sea. | A historical prototype demonstration, not evidence that every current shipboard laser has the same capability. |
| LLD, ONR, April 2022 | A test at White Sands tracked or shot down fixed-wing UAVs, quadcopters, and high-speed drones representing subsonic cruise missiles. | A ground-based system test, not a shipboard combat engagement. |
| ODIN, NAVSEA, May 2026 | A new operator-training program covered tracking, locking, firing the dazzler, and managing alerts. | The report describes a sensor-dazzling mission and said ODIN was not a Navy program of record at that time. That status is specific to the report date. |
How does the laser stay on target from a moving ship?
The director has to maintain a usable line of sight despite motion by the target and the ship. An initial sensor track helps point the optics in the right direction; optical acquisition and tracking then support continued aim. That is the public-facing outline, not a complete engineering description.
The cited Navy accounts do not state quantitative limits for ship motion, spray, humidity, cloud, haze, rain, or sea state. Nor do they publish general range thresholds, tracking error, beam dwell requirements, or the algorithms used. Those factors can constrain an engagement, but the reports cited here do not support assigning them universal numerical limits.
What these reports do—and do not—show
- They show that a naval laser can be cued by a wider defensive sensor or combat system, then optically tracked by its director.
- They document particular moving-target trials, including LaWS tests at sea and a separate LLD test at White Sands.
- They describe different intended effects, from LaWS’s reported range of disabling through destruction to ODIN’s sensor-dazzling role.
- They do not establish that any one system can defeat every drone, missile, or boat in all weather and sea conditions, or that a historical prototype test represents current fleet capability.
Why laser safety remains a military procedure
NAVSEA’s laser-safety materials address Navy and Marine Corps procedures for identifying and controlling laser-radiation hazards, along with review responsibilities for products not already approved by the Navy Laser Safety Review Board. These are controlled military systems; consumer laser pointers and ordinary laser safety glasses are not substitutes for the applicable military safety procedures.
