The increased EW capability that UFP dreadnoughts demonstrated was apparently not only a function of more space available to fit in various systems but also a power budget that left even Federation heavy cruisers in the shade. Starfleet dreadnought type ships in general were known not only for their heavy firepower, armor and shielding, but also for having a more extensive & comprehensive Electronic Warfare capability than other Starfleet warships, for example Federation-class vessels were known to be equipped with a holographic decoy system that could fox even sophisticated sensor systems, while the Star Empire-class had a holographic camouflage system that could disguise the ship as another ship altogether, among other things. The third comes from Star Trek Into Darkness, where the USS Vengeance was identified as a Dreadnought-class warship.

Another is Dreadnought, the name B'Elanna Torres chose for the captured ATR-4107 missile in VOY: " Dreadnought". The outline of a three nacelled Federation-class ship is briefly glimpsed in Star Trek III: The Search for Spock computer screens on the USS Enterprise. The dreadnought named Entente, was derived from Franz Joseph's Star Fleet Technical Manual, which also states that it is a Federation-class dreadnought. There are only three known direct on-screen references to a dreadnought one comes from the radio chatter in the first Epsilon IX scene in Star Trek: The Motion Picture. The Dreadnought-class USS Vengeance was an example of this type of vessel in the alternate reality.

B'Elanna Torres spent nearly a month reprogramming its computer and upgrading its systems, and eventually named it Dreadnought owing to its formidable nature. In 2370, the Maquis captured a defective Cardassian ATR-4107 missile. The Federation-class USS Entente was an example of this type of vessel.
