"The USG Ishimura (石村) , named after astrophysicist and inventor of the ShockPoint Drive, Hideki Ishimura, was the flagship of the Concordance Extraction Corporation and the first Planet-Cracker class ship. The Ishimura was also the first vessel of its size to utilize the ShockPoint Drive for large-scale commercial and deep space expeditions.

Built in 2446, the Ishimura was hailed as the savior of Earth and the colonies, and a symbol of Mankind's innovation. She was created for mining and smelting entire planets and moons. She was also the first ship capable of the "scan and catch technique" for harvesting mineral-rich asteroids using huge gravity tethers. The Ishimura had the ability to lock onto asteroids and pull them into her massive collection bays for smelting. Despite being designed primarily as a mining vessel, the Ishimura also functioned as a medical research vessel. She had a dedicated medical wing, where extensive research into virology, toxins and genetics was conducted.

At the time the Red Marker was discovered on Aegis VII, the Ishimura was 62 years old. She was still in remarkable shape, with much of her equipment upgraded and many sections refitted to take advantage of continuing advances in technology. Despite her long years of service, the Ishimura was still the pride of the C.E.C fleet, along with her venerable prestige as the largest Planet-Cracker class ship.
Ishimura arriving

When the C.E.C learned of Aegis VII Colony's discovery, the Ishimura was dispatched to recover the Marker and transport it back to Earth. Upon arriving at Aegis VII, the Ishimura's commanding officer and devout Unitologist Captain Matthius gave a no-fly order with the exception that the Marker, all related data and corpses be moved to the Ishimura. Once this was accomplished, the crew of the Ishimura began planet crack operations, with the cover put in place to hide their true agenda.
Coinciding with the planet crack, the Ishimura briefly lost all contact with the colony. Once contact was re-established, the crew discovered that the entire colony had been slaughtered. Further contact with one of the mining teams revealed nothing of the colony's fate, as they were soon killed by unknown hostiles. Several survivors attempted to reach the Ishimura using the colony's remaining shuttles. After navigating through the debris field created by the planet crack, the shuttles were fired upon by the Ishimura's ADS cannons for violating the no-fly order. Two shuttles successfully reached the Ishimura; the first, flown by Colin Barrow, crash landed into the hangar bay. The second, flown by Gabe Weller, crash landed on the hull near the Crew Deck."
