A laser-based system with laser detection and ranging ("LADAR") and semi-active laser ("SAL") system capabilities is disclosed. In a first aspect, an apparatus includes a gimbal capable of scanning in azimuth and in elevation and a sensor mounted on the gimbal capable of LADAR acquisition and laser designation. In a second aspect, a method includes flying an airborne vehicle through an environment, scanning a LADAR signal from a sensor into the field of regard to identify a target; and laser designating the identified target with the sensor.
