A system configured to be carried by a guided ordnance for in-flight target coordination with other guided ordnances, the system comprising: a forward-pointing optical imager configured to capture in-flight images of a scene aligned with an ordnance axis in a forward direction of ordnance travel, each of the captured images comprising a two-dimensional array of pixel data; and an image processor, characterised in that the system further comprises: an aft-pointing optical emitter configured to emit a first optical beacon in an aft direction of ordnance travel, thereby communicating to trailing guided ordnances, wherein the image processor is configured to identify, within the captured images, a second optical beacon emitted by a leading guided ordnance; a Guidance, Navigation, and Control,GNC, module configured to: chart a trajectory of the leading guided ordnance; a target identifier configured to identify one or more image portions within the captured images, each image portion comprising a subset of the two-dimensional array of pixel data corresponding to a target in the aligned scene; and a target selector configured to predict a first target selected by the leading guided ordnance, the first target corresponding to a first one of the one or more image portions, the first target based on the charted trajectory of the leading guided ordnance, the target selector further configured to select a second target corresponding to a second one of the one or more image portions, the second target located within a navigable range of the guided ordnance. a forward-pointing optical imager configured to capture in-flight images of a scene aligned with an ordnance axis in a forward direction of ordnance travel, each of the captured images comprising a two-dimensional array of pixel data; and an image processor, characterised in that the system further comprises: an aft-pointing optical emitter configured to emit a first optical beacon in an aft direction of ordnance travel, thereby communicating to trailing guided ordnances, wherein the image processor is configured to identify, within the captured images, a second optical beacon emitted by a leading guided ordnance; a Guidance, Navigation, and Control,GNC, module configured to: chart a trajectory of the leading guided ordnance; a target identifier configured to identify one or more image portions within the captured images, each image portion comprising a subset of the two-dimensional array of pixel data corresponding to a target in the aligned scene; and a target selector configured to predict a first target selected by the leading guided ordnance, the first target corresponding to a first one of the one or more image portions, the first target based on the charted trajectory of the leading guided ordnance, the target selector further configured to select a second target corresponding to a second one of the one or more image portions, the second target located within a navigable range of the guided ordnance. an aft-pointing optical emitter configured to emit a first optical beacon in an aft direction of ordnance travel, thereby communicating to trailing guided ordnances, wherein the image processor is configured to identify, within the captured images, a second optical beacon emitted by a leading guided ordnance; a Guidance, Navigation, and Control,GNC, module configured to: chart a trajectory of the leading guided ordnance; a target identifier configured to identify one or more image portions within the captured images, each image portion comprising a subset of the two-dimensional array of pixel data corresponding to a target in the aligned scene; and a target selector configured to predict a first target selected by the leading guided ordnance, the first target corresponding to a first one of the one or more image portions, the first target based on the charted trajectory of the leading guided ordnance, the target selector further configured to select a second target corresponding to a second one of the one or more image portions, the second target located within a navigable range of the guided ordnance.
