No, Russians were really trying to push the plasma stealth bullshit, and were researching it hard. The US did some work into it too, during the A-12/SR-71 program, with the Kempster A program. Which were basically ion cannons placed close to the intake ducts pointing forward to shield the frontal return from the engine nacelles that generated ion clouds to absorb the radar energy before it can reflect back to the radar. They also added a cesium based additive to the JP-7 fuel in the A-12/SR-71 to, again, create an ion cloud to shield the exhaust plume and turbine rotors/blades against radar from the rear. It was supposed to help with limiting the exhausts IR radiation, too. It was called A-50, or "Panther Piss". I don't really like linking TWZ, but, the info is accurate and all there without me having to go through my docs to find the books and CIA/NRO documents that talk about these efforts, and I really don't feel like doing that right now.

The Soviets were also working on seeding the wake behind their ICBM RVs with sodium to do a similar role as Panther Piss did for the A-12/SR-71. This comes from a declassified report on Soviet stealth efforts and technologies during the '80s that I have somewhere on my comp, just don't feel like digging it out.

THOUGH, stealth plasma can work, but, most of the time it's actually going to increase your RCS substantially, and only reduce it a little when it does actually work.
