The Assault-class was a type of starship utilized by the Hierarchy in the 24th century, equipped with advanced short and long range sensors, including micro-tunneling sensors. The Assault-class ship commanded by Loquar in 2377 was classified as a survey vessel not equipped to fight enemy ships. (VOY: "The Void") Other ships of this class used for raiding enemy ships were classified as assault vessels, more heavily armed, with three ships capable of outgunning a Starfleet Intrepid-class with heavy phaser armaments that could be set to fire on rotating frequencies. The assault ships were also equipped with stealth technology.
