The first attempt at a plasma ring weapon was successful enough to be classified immediately and nobody has heard anything since. Usually that's a sign that the project was successful and further research classified/suppressed.
I've seen similar happen with Free Election Lasers and EMP weapons in recent years. And with radar stealth before that.
Another tech that seems to have been suppressed is visual/IR stealth technology dating back to Yehudi Lights. https://en.m.wikipedia.org/wiki/Yehudi_lights . God knows what's out there now but it isn't hard to believe that we have nearly perfect visual stealth
