Genuine question: why does the USAF not do sick camo paint schemes? (Not counting aggressors) Is it just a cost vs. usefulness thing?

My bad for being stupid enough to get sucked into a stupid argument with stupid people.Platystemon posted:Stridsvagn 103 is a prime example of weird Swedish materiel. CommieGIR posted:And it kicked rear end. It's a bit like I-153, or the XB-70, which got rendered surplus even before it was finished by better missile technology, or the Saunders-Roe Princess. I'm trying to think of other aircraft that suffered the same fate. Something like the B-36 doesn't count because it was a successful design, even if it was clearly the last effort of an older technological era. Nor does something like the F-82 Twin Mustang, which was intended to be an interim solution from the beginning of its service.

Anything that could hit a military jet at distances where camo would be actually visually resolved (and camo against what? They are flying over all sorts of terrain etc) won't be put off or confused in the slightest by it. Visible range matters so little for fighter engagement that might as well paint it whatever is the hardest to spot at distance and call it a day.

F-18s should obviously be painted to look like another F-18 with buddy stores, so as to best blend in with their natural backdrop.

Luneshot posted:Genuine question: why does the USAF not do sick camo paint schemes? (Not counting aggressors) Is it just a cost vs. usefulness thing? The USA's current tactics are all based around flying big heavy airplanes way up high against enemies with no air force. Pale gray blends into the haze when you're trying to spot the F-15 dropping bombs on you from 25,000 feet. If hiding down in the weeds was still something that they needed to do, or if there were any threats coming from above instead of below, you'd probably see camouflage coming back. Look-down-shoot-down radar has made a lot of it obsolete, but a camo paintjob would still be beneficial in a low-altitude dogfight -- if there was anyone still doing that.

Combine the tower with a plane tracking app like Flightradar24 and it can be a nice way to kill 30 minutes.

CarForumPoster posted:Yes and the Navy publishes it here: http://www.navair.navy.mil/nawcwd/ewssa/downloads/NAWCWD%20TP%208347.pdf Just scanning through and I want to pull out a couple choice nuggets because the topic of AESA comes up fairly frequently: LOW PROBABILITY OF INTERCEPT posted:Since the AESA can change its frequency with every pulse, and generally does so using a pseudo-random sequence, integrating over time does not help pull the signal out of the background noise. Nor does the AESA have any sort of fixed pulse repetition frequency, which can also be varied and thus hide any periodic brightening across the entire spectrum. Traditional RWRs suffered significantly decreased effectiveness against AESA radars. HIGH JAMMING RESISTANCE posted:Since an AESA could change its operating frequency with every pulse, and spread the frequencies across a wide band even in a single pulse, jammers are much less effective. Although it is possible to send out broadband white noise against all the possible frequencies, this means the amount of energy being sent at any one frequency is much lower, reducing its effectiveness. In fact, AESAs can then be switched to a receive-only mode, and use these powerful jamming signals instead to track its source, something that required a separate receiver in older platforms. OTHER ADVANTAGES posted:Since each element in an AESA is a powerful radio receiver, active arrays have many roles besides traditional radar. One use is to dedicate several of the elements to reception of common radar signals, eliminating the need or a separate radar warning receiver. The same basic concept can be used to provide traditional radio support, and with some elements also broadcasting, form a very high bandwidth data link.

Sagebrush posted:This has reminded me of something I've always wondered about : is there a good (unclassified) article or publication somewhere that explains exactly what EW aircraft are doing? Like, on a level that's more technical than wikipedia's "they jam the radars " -- what sort of techniques do the electronics use, what's the technical basis for it, what are the EW officers doing moment-to-moment, how far away can they do it from, what does it actually do to the enemy radar, how do you counteract it, all that stuff. What you want is Lärobok i telekrigföring för luftvärnet: radar och radartaktik (Electronic Warfare Textbook for the Air Defense: Radar and Radar Tactics), a 440 page textbook published in 2004, going over all the basics on exactly how radars and jamming them actually works (in layman's terms - it is written to be understandable to someone with a high school education, i.e. officer cadets), as well as tactical fundamentals for the use of radar and radar countermeasures. Unfortunately, it is in Swedish, and since it's long as gently caress I can't really translate much for you. It does cite a bunch of English references/sources, but when I googled them they tend to be books that are $100 or so on Amazon...

LOVING that Swedish book, also loving the craftily translated terminology:Nice piece of fish posted:"Vilseledning", "åtgärder" Åtgärder is a normal phrase but vilseledning is fantastic. Perhaps it's in normal use as well, but as translation for spoof or decoy it does the job much better than the Norwegians who'll just say it in English with a local pronunciation. Maybe the Swedes do as well and are only linguistically strict in literature. "Kolla grabben, ryssjävlar! Skicka dikåis, spoofa dom för fan!"

Ask the scandithread and you'll get about fourty different opinions. It's more like the difference between south african english and heavily accented scottish, if it isn't officially completely seperate and not really mutually intelligible language, it's close enough to that to not really matter. Norwegians understand spoken swedish and written swedish and danish, swedes don't understand anything and nobody understands spoken danish. That's basically it.
