[edit] Error
"An F-117 was also detected by a British ship during the first Gulf War, in this case because the wavelength of the radar was twice the length of the aircraft. This caused the entire aircraft to act as a dipole, leading to a very strong radar return"
The F-117 is over 20m long, so was the radar transmitter 40m wide? Seems unlikely! Guinnog 20:42, 19 April 2006 (UTC) It says elsewhere that components inside Stealth planes may acts dipoles. That makes the dipole about 1m say, which is reasonable for a radar antenna. But if this is true ( and I can't see why the British radar might be unique )then Stealth planes are easy to detect in any case . 145.253.108.22 14:08, 20 February 2007 (UTC)
[edit] Comment on List of Stealth aircrafts
It seems to me that there has been an effort by some editors to elongate the list. Honestly, US is the only stealth aircraft producing country currently.
It's unnecessary to put aircrafts that "kinda" look stealthy. Some of them aren't stealthy at all.

- If you would actually read the articles associated with each of the aircrafts (sic) you deleted, you would see that there is rationale to their inclusion in the list that extends beyond "kinda" look stealthy. I'm fixing the list to the way it was. Give Peace A Chance 05:04, 17 July 2006 (UTC)
[edit] A lot of what press calls stealth is simply reduced RCS
We must differentiate between the few "full" stealth aircraft like the F-117 and B2 and the many limited radar signature (reduced RCS) planes like F-22, JSF, MiG 1-44 or Rafale. Because of the great cost and awkwardness of operation with true full stealth, the future of manned combat planes is with reduced RCS. Unmanned planes are more likely to become full stealth however, as the lack of a cockpit and canopy simplifies stealth design and their lower manouverability and lack of onboard brain means complete non-detection is more desirable. In a manned plane you can count on the pilot to do impressive aerobatics if needed, to save his/her own precious rear from a SAM. So full stealth is less desirable there, they choose supercruise instead.
So I split the manned list into full stealth and reduced RCS paragraphs and also added the Rafale, which is low RCS (and quite beautiful, as you would expect from a chic french airplane).
The swedes claim JAS-39 Gripen is low radar observability, which is laughable if you look at its boxy air intakes, so I did not include that. 195.70.32.136 18:45, 11 August 2006 (UTC)
[edit] Full Stop - Define "Full Stealth"
What's full stealth? Give a citation for it, or it's getting deleted. This article is a horrible accumulation of original research and speculation. Not suprising given the secret nature of it, but still, this is fairly bad. --Mmx1 22:35, 11 August 2006 (UTC) Stealth is the science of reduced radar cross-section,reduced dependence on aerofoil lift and reduced dependence on chemical propulsion. Demonstrated on B2A during 1999 UK. This article almost seems like disinformation. One of the potential drawbacks is defecting? This has never happened with any stealth aircraft. Only a Mig 25 that I am aware of (not stealth, though advanced for its time). Also, bombers like the B-2 very rarely circumnavigate the globe on an 19 hour flight based on a tactical mission. Instead many such aircraft B-1's, B-2's are on standbye in and around hot spot regions. The article also refers to shooting a stealth down with a canon mounted on an airliner. That is hard to do if you can't detect a plane on radar. The days of sacrificing performance for stealth are over...as evidenced by newer designssuch as the F/A - 22 an YF-23. Survivable future combat systems will combine stealth (visual, acoustic, ir, and radar) combined with supercruise and high performance to render a very low probability of intercept. Future stealth aircraft will be very lethal combat systems. 143.166.255.17 01:40, 16 August 2006 (UTC)Hans
- No, this article is the way it is because the people that know, don't tell. And the people that write, don't know jack shit. I fall into the "I have better things to do than speculate on highly classified info" camp; but it's sort of amusing to watch. --Mmx1 01:53, 16 August 2006 (UTC)
- I have tagged this article for expert review. Besides lack of source citations, it has undefined categories, technical errors, and seems to portray a negative POV on the subject. As it stands, I don't see any reason to have such an article as this; it could be more tidily handled in the Stealth technology article. --Askari Mark | Talk 04:14, 5 September 2006 (UTC)
[edit] Cleanup work
I've tagged this more accurately. Not only does it read like a school essay, it also contains enough bullet points that Jimbo may start having to ration them. Paragraphs, people. Sourced, verified paragraphs. Chris Cunningham 00:30, 14 October 2006 (UTC)
"In July 1999 two days prior to the Royal International Air Tattoo at RAF Fairford UK, a single B2A Spirit penetrated UK airspace at 01.30 hours. Passing overhead reporting point Whisky Delta 2 at approx. 250 feet it was traveling at just above stalling speed and was completely silent. The anterior half of the aircraft structure was covered in a green-white condensation cloud." I noticed this tacked into a bulletted bit in the Drawbacks section. Da hell is this?Dxco 01:37, 30 December 2006 (UTC)
- No idea. I've just removed it though as it didn't seem to fit anywhere in the article (which I agree is of poor quality). --Nick Dowling 06:36, 7 January 2007 (UTC)
[edit] Star Trek
Where the hell do we get 'plasma screens' on russian aricraft? Is there a basis for this ( apart form watching too much Star Trek )? 145.253.108.22 14:10, 20 February 2007 (UTC)
- Well, it is theoretically possible to create a "plasma bubble" around an object that traps incoming radio waves, thus getting the RCS of zero. Two problems with this idea are too big to be currently feasible. First, it's really hard to maintain the plasma around an object and aircraft's small size makes it difficult to carry all necessary equipments. Second, any object surrounded by plasma literally "shines" to someone watching it. It's almost like wearing black clothes to hide in the dark and then carrying a lantern around to find the way.--Revth 09:03, 26 February 2007 (UTC)
[edit] From a page comment
User:69.88.253.62 added this in-page on 19:14, 7 March 2007:
[I don't have enough time to incorporate this fact in, but the F-117 is able to carry AIM-9's. Someone with more time should be able to fix this.]

[edit] Question
Can stealth aircraft glide relatively silently, with engines off? kabbelen 22:31, 22 March 2007 (UTC)
- Welcome! First, new questions should be posted at the bottom of a talk page, rather than the top (so I have taken the liberty to move it).
- As to your question, it would have more to do with the design of the airplane's aerodynamics, flight controls and – particularly – the engines, not whether the airplane was "stealthy". Tactically, I'm not sure you would want to turn off your engines in mid-flight; it could make you an easy target for an enemy fighter who could visually acquire you.
