I stared at Bill for a moment. "Jeez. I must be getting old. Okay, so, some kind of radar-proofing, carbon-black exteriors to foil visual, low-power electronics combined with a super-cooled heat sink to counter infrared detection ..." I sat forward as my enthusiasm mounted. "We can coast in, we don’t need to use cloaking since they don’t appear to have SUDDAR. So we can use long-range SUDDAR to watch for patrols ... yeah, this is good!"
