A beam director system comprising: a source of electromagnetic radiation for generating a high energy laser, HEL, beam; a secondary mirror for receiving the electromagnetic radiation and reflecting the electromagnetic radiation to a primary mirror for output of the HEL beam through a housing, wherein the secondary mirror is curved and angularly expands the electromagnetic radiation received from the source prior to outputting the HEL beam from the primary mirror; an illuminator for generating a tracking beam to be directed at the target; a track telescope coupled to the housing, wherein the track telescope has a track detector configured to receive a first and a second portion of the electromagnetic radiation of the HEL and at least a portion of the tracking beam reflected from the target; a first reflecting surface to route the first portion of the electromagnetic radiation of the HEL beam to the track detector; a second reflecting surface to route the first portion of the electromagnetic radiation of the HEL beam to the first reflecting surface, a third reflecting surface to route the second portion of the electromagnetic radiation of the HEL beam to the track detector and a fourth reflecting surface to route the second portion of the electromagnetic radiation of the HEL beam to the third reflecting surface; and a processor coupled to the track detector and a steering controller of the HEL beam, wherein the processor processes the first and second portions of the electromagnetic radiation of the HEL and the portion of the tracking beam reflected from the target and generates an input signal to the steering controller to steer the HEL towards the target. a source of electromagnetic radiation for generating a high energy laser, HEL, beam; a secondary mirror for receiving the electromagnetic radiation and reflecting the electromagnetic radiation to a primary mirror for output of the HEL beam through a housing, wherein the secondary mirror is curved and angularly expands the electromagnetic radiation received from the source prior to outputting the HEL beam from the primary mirror; an illuminator for generating a tracking beam to be directed at the target; a track telescope coupled to the housing, wherein the track telescope has a track detector configured to receive a first and a second portion of the electromagnetic radiation of the HEL and at least a portion of the tracking beam reflected from the target; a first reflecting surface to route the first portion of the electromagnetic radiation of the HEL beam to the track detector; a second reflecting surface to route the first portion of the electromagnetic radiation of the HEL beam to the first reflecting surface, a third reflecting surface to route the second portion of the electromagnetic radiation of the HEL beam to the track detector and a fourth reflecting surface to route the second portion of the electromagnetic radiation of the HEL beam to the third reflecting surface; and a processor coupled to the track detector and a steering controller of the HEL beam, wherein the processor processes the first and second portions of the electromagnetic radiation of the HEL and the portion of the tracking beam reflected from the target and generates an input signal to the steering controller to steer the HEL towards the target.
