The DCS Pacheco was a Vigilant-class WarShip in service to the Draconis Combine. One of the few remaining WarShips in the Inner Sphere after the First Succession War, it was deployed in the Combine's attack of the Hesperus system in 2853 as one of a trio of corvettes forming the zenith jump point blockade fleet (along with the Tamura and the Georgia).
The Lyran Commonwealth famously reactivated their ancient battlecruiser LCS Invincible to break through the Combine siege. The Invincible jumped to the Hesperus system's nadir jump point on 25 October 2853 and smashed through the Combine blockade vessels, with a relief fleet behind it. As the Lyran fleet moved towards Hesperus II, the Draconis Combine recalled the corvettes from the zenith jump point blockade fleet to a pirate jump point near the planet, to bolster the planetary blockade fleet. However, in the face of superior Lyran firepower the Draconis Combine fleet was quickly forced to retreat. It was not specifically spelled out which vessels were lost in the battle for either side, though all Draconis Combine WarShips that had participated in the blockade were destroyed.
