The Qektoth Attack Cruiser was a design that was put in service for the Qektoth Confederacy four years after the Battle of Endor. It is unclear whether these ships were constructed from the keel up by the Confederation or were conversions of the ships received in the deal brokered by its leader, Trann Shoame. The first vessels in the line were the Scourge and The Heart of Flesh. While both vessels were designed concurrently, the Scourge was completed first, while the latter vessel was being perfected at a secret facility inside the Kathol Rift. Both of these vessels however, were destroyed in engagements against the New Republic Corvette FarStar. Many weeks after, at least three additional cruisers were completed.

    With each iteration improvements were made to the design. In the first, the Scourge, was a starfighter scale vessel. Due to the biological weaponry's incredible energy requirements, the design suffered from severely limited shield coverage. To partially offset this weakness, it could only attack a single foe and only if it had surprise on its side. The second iteration, The Heart of Flesh kept the same arms, but became a capital scale vessel and featured increased shield arc coverage. Interestingly, the ship's weapons were independent of the reactor, and thus could not sustain ionization damage. Meanwhile, the third iteration vessels took the characteristics of the previous generation, but introduced all capital scale weaponry.

    The bio-energy array is stored behind a circular hatchway in the ship's nose and is only revealed when the Qektoth Attack Cruiser does combat. Once revealed, the weapon mounted on a platform, is a dark green tangled mass of sinew with beige ovals, effectively appearing similar to that of a biological version of a sensor array. When fired, tendrils of blue electricity jump from one sinew to another, eventually unleashing fierce streaks rough, forked lightning at its target. This frightening weapon, along with the plasma cannons completely ignore shields.
