Doesn't need to be undetected, just fast enough that the escapee doesn't get shot and slow enough that the escapee doesn't die from the G-forces. There's a lot of room between those two extremes. You'd have to install drone guns to protect against the escape drones, but are invulnerable to attacking drone guns. This could get ugly.
