In a missile tracking and guidance system, a fiber optic link is maintained between a missile and the launcher. Tracking after launch is via a video link between the missile seeker and a video imager at the launcher. Guidance signals are derived from the video signal input to the imager and transmitted back to the missile. Additionally, rate sensors and an interrupt or reaim circuit within the launcher allows an operator to reacquire the target for refining the missile seeker look axis toward a target during flight. After the target aimpoint is refined the operator can then release the interrupt circuit, allowing the system to continue tracking from the video input, with a newly established seeker heading established during the aimpoint refinement.
