The IKS Ectacus was a Klingon battle cruiser in Imperial Defense Force service in the 23rd century.
Service history[]
In the year 2267, the Ectacus traveled to the neutral planet Eulus. The commander purchased exclusive dilithium mining rights to the planet, signed by treaty with the Grand Qaal, then returned to the Ectacus with a sample case of dilithium, unaware that they were being conned with cheap synthetic dilithium by Harry Mudd. After uncovering the fraud, James T. Kirk and Spock beamed aboard the Ectacus to recover the unstable crystals before they destroyed the ship and incited a war. (TOS comic: "Operation Con Game")
