This is something the military, e.g. fighter jets worry about. The altitudes (in a given airspace) that form contrails are briefed as part of "tactical weather". You try to avoid them if able, because no matter how stealthy you are, you are lit up for all to see if you fly at those altitudes.
- aerostable_slug 1y agoFun fact: the B-2 bomber has a LIDAR-based contrail detection sensor, called the Pilot Alert System. https://tridsys.com/our-divisions/optical-precision-sensors/ https://tridsys.com/our-divisions/optical-precision-sensors/
- Den_VR 1y agoThere’s always been something disturbing about public internet advertisements of military equipment. I suppose it’s dual use, but it seems like baiting a malicious actor to play with it in detail.
- Agree2468 1y agoIf you're ever in DC, you should check out the ads in the metro stops near the Pentagon. Seeing those kinds of ads in real life is even more shocking.
- Retric 1y agoWalked into a weapons show a few decades ago that had a full scale Abrams tank + demo camera providing good 360 degree visibility. It was odd because I was like yea this is obviously a good idea, but also I’m not the person you need to convince here so WTF.
- kiba 1y agoIt's designed to convince their customers which are other countries.
- varenc 1y agoHow'd you find a weapons show? Which one? are these semi-open to the public? Sounds fascinating
- Retric 1y agoI was walking around Arlington VA area and saw some signs of fighter jets and such that looked interesting, no idea of the show beyond that really. I did have a pentagon badge at the time which let me in, not sure if it was necessary though.
- Cthulhu_ 1y agoYou're not but there may be people that are. Besides, tanks are cool and I'd go to shows like that for entertainment purposes. I went to the Dutch military museum the other day, it has a Leopard tank outside (and of course a collection of tanks and the like indoors, including a German V2 rocket suspended from the ceiling).
- extraduder_ire 1y agoI saw some photos of those ads on twitter a few years back about a certain manufacturer's engine being the correct choice for a specific in-development military plane. It's weird seeing physical advertising be so targeted. Like, multiple physical ads to target less than a dozen people total.
- jfengel 1y agoIt's a little broader than that, because these are general defense contractors who have their fingers in every pie. So it's seen by contracting officers, partners, potential employees, etc. It's a bit like a Coke ad -- you do not need to be informed about Coke, but it creates an atmosphere of nebulous positive feelings. Still, kinda weird.

- datadrivenangel 1y agoThe tech billboards in SF are also wild.
- Agentlien 1y agoI'm someone living far off in remote Sweden, could you explain with some examples?
- imglorp 1y agoIf you think advertising to a dozen people is wild, wait till you hear about bribery of six! It's more efficient!
- Cthulhu_ 1y agoIt makes sense though, given that those dozen people have decisive power to bring billions of dollars in revenue and decades of work to the companies advertising. Like, the Dutch airplane manufacturer Fokker went bankrupt and stopped manufacturing planes in 1996, but the brand and company are still very much alive, manufacturing parts and providing maintenance services to all their planes still in operation worldwide.

- ecshafer 1y agoIf you desire peace, prepare for war.
- quesera 1y agoIf your preparations for war are influenced by advertising in the DC Metro, you are not a serious professional who the public can trust to desire peace.
- philipallstar 1y agoThis is the sort of response I'd hope an AskJeeves AI would generate.
- bigfatkitten 1y agoThe billboards at Canberra airport almost exclusively advertise defence contractors. Lockheed Martin, BAE Systems, Northrop Grumman and Qinetiq know how to reach their audience.
- asdff 1y agoThere is something deeply sinister about seeing a defense contractor building in and around DC. Very nondescript 80s-90s dark plexiglass office box with a parking lot. Only with metal fencing, coated in cameras, anti ram bollards, and an armed guard at the gate, plus no doubt other security measures we can't see. The most secretive cutting edge science on death and killing being performed in the most otherwise happy go lucky seeming 90s model suburbia where there seemingly aren't any poor people around at all. Something deeply dystopian about this model utopia optimized for an ever present and unstoppable war machine.
- wil421 1y agoA malicious actor is probably not going to meet them at their place of business and do FBI background checks, in person DOD interviews, even polygraphs, to be able to really talk to them.

- protocolture 1y agoIf anything there should be more public info. Seeing people having to FOI request details of the chemicals they were exposed to in their service, is much more disturbing.
- tintor 1y agoB-2 is not dual use. There is no civilian use for it.
- LargoLasskhyfv 1y agoThere could be. As in "Fight fire with fire!" For stopping out of control forest fires, by bombing large and wide trenches, to stop them there.
- Angostura 1y agoSearch and rescue? /s
- aklemm 1y agoWe can bomb immigrants and protestors. Let your imagination soar in these innovative times!
- asdff 1y agoDOD says we can use thermonuclear bombs for making harbors and other civilian infrastructure so I'm sure there are some "peaceful" bullet points consultants came up with for B-2 as well.

- nickff 1y agoAvoiding con-trail creation has been a factor for military aviation since at least WWII; bomber pilots then were briefed on what altitudes to fly at to avoid them as well, but not because they were especially stealthy.
- thaumasiotes 1y agoThere's still some space between "not especially stealthy" and "drawing an enormous arrow in the sky pointing directly to you".
- citizenpaul 1y agoIts nice to see new tech being used to kill people for a change.
- aeternum 1y agoThis seems pretty useless in an age with super cheap 8k cameras and novice ability to do a delta-recorded image.
- Havoc 1y agoWhat do you mean by delta-recorded image?
- bob1029 1y agoThe fixed resolution of an image sensor can be augmented by capturing multiple frames over time. https://www.ipol.im/pub/art/2023/460/ https://www.ipol.im/pub/art/2023/460/
- zamadatix 1y agoSuper resolution is a thing but I think they mean to just take the differences and track based on the motions in that data directly. Any deltas which appear to move in a certain way are likely to be aircraft, especially if the same deltas show up on a 2nd camera, even if they aren't clear enough to directly identify. Basically the motion vector estimation step of video encode but tuned really tight and ignoring motions that don't look like aircraft motions. I'm not sure this is really all that perfect/foolproof though, especially with 8k visible light cameras. For one, clouds can be quite the problem (even at non-visible wavelengths). Atmospheric turbulence can also be annoying and the air can be plain hazy depending on the day - both limit detection accuracy at a given range. When night comes the detection ability is greatly hampered even with additional wavelengths (and IR has lower resolution anyways). It worked well enough in a weekend project many years back to use computer vision (the craze at the time) and compare to an ADS-B make by using a 4k 1 FPS image feed in a weekend project to mess with computer vision a decade back. I definitely see it as a valid addition to a detection system... but I would stop short of writing a "Military Dumbfounded at This One Simple Trick" article about it.
