no i havent been out of states in years...

if they say they build one, then they surely have a one that works

btw, Tu-180:


"Last week (April 1st, aka April Fool's or Den' Duraka) ANTK Tupolev revealed their latest strategic bomber designated Tu-180. Although Tu-180 was in service with Dal'naya Aviatsia for almost five years, it remained the Russia's best kept secret until now. The aircraft was developed alongside of Tu-160 bomber and it was designed to complement the supersonic Blackjack which was to become the backbone of the Russia's strategic command. Unlike Tu-160 it incorporates considerable amount of stealth (nevidimka in Russian) and it is believed that Tu-180 RCS is about 1/20 of Tu-160. New Tupolev bomber is a first true stealth design known to be in service outside of the United States."

"Tupolev claims that first flight was made on March 14, 1985"

Russia Working on Stealth Plasma

Russia is working to develop plasma-cloud-generation technology for stealth applications and achieved highly promising results, reportedly reducing the radar cross-section (RCS) of an aircraft by a factor of 100.

Russian research into plasma generation is spearheaded by a team of scientists led by Anatoliy Korotoyev, director of Keldysh Research Center. The institute has developed a plasma generator weighing only 100 kg, which could easily fit onboard a tactical aircraft. For the system to work, there has to be an energy source on the aircraft that ionizes the surrounding air,probably at the leading surfaces. Since the resulting ions are in the boundary layer of the aircraft, they follow the airflow around the plane. But the system is not without drawbacks. First, the amount of power required is quite high, so it will likely only be activated when an enemy radar is detected. The other is that the plasma also blocks the radar of the aircraft being protected, necessitating holes in the plasma field to look through it.

The plasma generator was tested first on flying models and then on actual aircraft. The new Su-27IB strike aircraft (known in export - certainly without the plasma generator - as the Su-32) utilizes the system and is likely the first production combat aircraft with this critical technology.

As you see Russia is not that bad at tech uh?

They do have plasma stealth that WORKS!

Folks,
There are two important points being missed on the topic of Plasma Stealth. 1st, Plasma Stealth is not needed because US designed technologies in conventional stealth technologies, such as shaping, RAM, IR supression, and LPI emitters, have already produced LO aircraft which are virtually indistinguishable from background noise and clutter. The challenge is to design an LO aircraft with advanced combat capabilities that incorporate these LO technologies without sacraficing performance.

I know for a fact that the USAF has designed prototype systems that are so LO that they can be detected by the "hole" in the clutter and multipath that they produce as they transit the battlespace. To go that LO is pointless. Up to a certain degree stealth is pretty much a moot point and begins to demand too much from your airframe. And besides, as it has been repeatedled pointed out but rarely acknowledged, the object of stealth is to provide a tactical advantage on the battlefield, not to produce total invisibility for an aircraft, otherwise it would be called "invisibility" and not "stealth". A large portion of stealth involves mission planning and electronic warfare, anyways.

2nd, why would anybody waste their time on developing a stealth system that runs on electrical power? The whole point of stealth is to reduce your signature....all signatures...including electromagnetic. Produce a signature, not matter what spectrum you are using, and the enemy will devise a system to detect to emanations. Ionized plasma is a high-power energy source, which can be detected at extended ranges. And besides, what happens when your crappy Czech electrical generator konks out over enemy territory? No more plasma - no more reduced radar signature.

Now I'm not saying that the Russian industrial base is incapable - we all know that is not the case. Just look at the aircraft Suhkoi is producing. Masterful. However, plasma stealth will never be a practical way of providing low observability in the tactical battlespace, especially at low altitudes, for combat aircraft. Maybe, just maybe, it could be useful on large, high-altitude recce and spacial mission aircraft of high value. But not on a fighter or attack aircraft.
