TBH I'm fairly sure I saw a Fed ship disappear a couple of times when I was messing around with my Klingon in PvP the other day...
As everyone else has said, that's what Jam Sensors looks like on the receiving end. The enemy ship just disappears from your screen and you get the sparkly blue effect around your ship.

If they are the same I'd just acquire some of those skills and shove them back in their faces. On Fed side one of my BOs has Science team which can remove sensor debuffs.
They get access to all the same abilities. I'd just guess that most people don't know enough about the game to go to the skill trainer and swap out their starting BO abilities when they first make a Klingon.
