dreadnought

Perturbed at being overtaken, the USS Texas is leading the 6th Battle Squadron at 22-and-a-half knots as the engineers pour everything they have into the effort. Behind the colossal clouds of smoke and cinders they put out come a seemingly-endless stream of dreadnoughts, battle flags flying from every mast and line they can find. It is the Grand Fleet.

Sovereign is the flagship of the rogue Spectre Saren. An enormous dreadnought larger than any other ship in any known fleet, Sovereign is crewed with both geth and krogan. At two kilometers long, its spinal-mounted main gun is likely capable of penetrating another dreadnought's kinetic barriers with a single shot.

"Much obliged to you, ma'am!" says Mr. Guppy, divesting himself of his wet dreadnought in the hall.
