Could optics and radar keep pace with longer-range guns?

What could the research programme achieve in optics for sighting and fire control?

It would encourage optical manufacturers to improve sights and lenses alongside the guns; radar before World War I remains doubtful, though sustained incentives could bring it forward.

Optical manufacturers would have reason to improve their products as guns reached farther. Vickers made sights, while firms such as Taylor Hobson supplied lenses that went into them. Better optical instruments would help a fleet use the range of its new guns. Radar faces more obstacles, making a working system before World War I doubtful in this scenario. Sustained incentives could nevertheless bring radar and radar-directed fire control forward, with the end of the war offered as a possibility.
