However, the base assumption is that the battle is taking place at sublight speeds in relatively close proximity.
Why would they use a different set of sensors? For that matter, why engage in a "close proximity" fight with weapons that have effective range and power at superluminal speeds? Since the warp drive was obviously functional...
The Picard Maneuver belongs in the same fantasy tactics category as the "dogfighting" one-man ships in STAR WARS and BATTLESTAR GALACTICA.
The light delay between Earth and the Moon is about 1.3 secondsólong enough to matter when aiming weapons in a space battle. Yet 1.3 seconds is hardly an advantage worth mentioning with ships and weapons designed to engage at FTL speeds. So again, the Picard Maneuver is nonsense.
