Except maybe for an early warning system. At any rate, it is not only like expecting an oxygen sensor to detect dirt, it is like expecting the oxygen sensor to detect that dirt while jetsetting around the system like bats out of hell. I am not certain that even a Geiger counter which is purpose-built to detect rads can detect a single rad at those speeds. They are recon drones, not magic wands.
Let's review the text that we already have to see why recon drones actually can find a spider drive ship; Mission of Honor, chapter 9: Unlike the starships of most navies, the MAN's scouts hadn't settled for simple smart paint. Other ships could control and reconfigure their "paint" at will, transforming their hulls—or portions of those hulls—into whatever they needed at any given moment, from nearly perfectly reflective surfaces to black bodies. The Ghosts' capabilities, however, went much further than that. Instead of the relatively simpleminded nanotech of most ships' "paint," the surface of Apparition's hull was capable of mimicking effectively any portion of the electromagnetic spectrum. Her passive sensors detected any incoming radiation, from infrared through cosmic rays, and her computers mapped the data onto her hull, where her extraordinarily capable nannies reproduced it. In effect, anyone looking at Apparition when her stealth was fully engaged would "see" whatever the sensors exactly opposite his viewpoint "saw," as if the entire ship were a single sheet of crystoplast. That was the theory, at least, and in this case, what theory predicted and reality achieved were remarkably close together. It wasn't perfect, of course. The system's greatest weakness was that it couldn't give complete coverage. Like any stealth system, it still had to deal with things like waste heat, for example. Current technology could recapture and use an enormous percentage of that heat, but not all of it, and what they couldn't capture still had to go somewhere. And, like other navies' stealth systems, the MAN's dealt with that by radiating that heat away from known enemy sensors. Modern stealth fields could do a lot to minimize even heat signatures, but nothing could completely eliminate them, and stealth fields themselves were detectable at extremely short ranges, so any ship remained vulnerable to detection by a sufficiently sensitive sensor on exactly the right (or wrong) bearing. In this instance, though, they knew right where the Graysons were. That meant they could adjust for maximum stealthiness against that particular threat bearing, and as part of his training, Sung had personally tried to detect a Ghost with the MAN's very best passive sensors. Even knowing exactly where the ship was, it had been all but impossible to pick her out of the background radiation of space, so he wasn't unduly concerned that Bogey Two would detect Apparition with shipboard systems as long as she remained completely covert. He was less confident that the spider drive would pass unnoticed at such an absurdly short range, however. Chernevsky's people assured him it was exceedingly unlikely—that it had taken them the better part of two T-years to develop their own detectors, even knowing what they were looking for, and that those detectors were still far from anything anyone would ever call reliable—but Sung had no desire to be the one who proved their optimism had been misplaced. Even the Spider had a footprint, after all, even if it wasn't something anyone else would have associated with a drive system. All it would take was for someone to notice an anomalous reading and be conscientious enough—or, for that matter, bored enough—to spend a little time trying to figure out what it was. And the fact that the Spider's signature flares as it comes up only makes that more likely, he reflected. The odds against anyone spotting it would still be enormous, but even so, they'd be a hell of a lot worse than the chance of anyone aboard Bogey Two noticing us if we just keep quietly coasting along. At the same time, he knew exactly why Tsau had asked his question. However difficult a sensor target they might be for Bogey Two's shipboard systems, the rules would change abruptly if the Grayson cruiser decided to deploy her own recon platforms. If she were to do that, and if the platforms got a good, close-range look at the aspect Apparition was keeping turned away from their mothership, the chance of detection went from abysmally low to terrifyingly high in very short order. Which meant what Sung was really doing was betting that the odds of the Grayson's choosing to deploy recon platforms were lower than the odds of her shipboard systems detecting the Spider's activation flare if he maneuvered to avoid her.
Thanks for producing that very important textev again. It is elsewhere on the forum, iinm. I almost included that vagueness of "absurdly short ranges" as a disclaimer. Like, maybe, if an RD hits the hull.  But I imagine inside energy range would be considered as absurdly short. But there does appear to be a chance for detection by RDs. I was wrong about that. Unless the Spider can keep its most stealthy face forward of the RD while inside those absurdly short ranges; which may be possible for a Spider that can move in eerie ways. Maybe not move quickly, but well enough. Also consider that the GA will not have the MA's specially designed sensors.
Son, your mother says I have to hang you. Personally I don't think this is a capital offense. But if I don't hang you, she's gonna hang me and frankly, I'm not the one in trouble. —cthia's father. Incident in ? Axiom of Common Sense
