The Larkinsons succeeded in bringing a warship online. They chose to spend their efforts on the Ailing Frey, as that happened to be the latest and most modern warship of the Allidus Alliance.
While it was too much to ask the incoming personnel to control the ship as well as the original crew, the Ailing Frey was not that difficult to bring online.
As long as the Black Cats hacked the ship systems and made sure to sweep them for traps and safeguards, the engineers and officers came face-to-face with friendly, user-friendly control systems.
This did not surprise Ves. A good maker always took his target audience into account. While the Allidus Alliance was certainly well-run, it couldn't ask too much of its own personnel! Most were pirates with mixed backgrounds. Expecting them to run a ship as complex as a CFA warship was way too unrealistic.
