In addition to their defensive function, the Sentinels also use any opportunity to expand their financial assets. The artificial intelligence keeps its developments secret, but some of its projects are still commercial by nature. For instance, at the end of 4623, the development of a new covert ops ship was announced to a narrow circle of people. Y40-Q290 was one of the most unconventional of the Sentinels’ projects. In addition to the control unit and adapted AI core, a new manual piloting system was developed for the ship, allowing even individuals without implants to control it. The ship also had a set of unique systems, including a new thermal weapon, as well as special and active modules.

In 4624, the finished ship went on sale to different factions and the UMC under the name “Pilum”. People immediately noticed the unconventional (for a Jericho ship) shape of the interceptor, and rumours about the ship’s connection to the sudden establishment of a Sentinels’ outpost on the border with the Damned Flotilla and the possible theft of Imperial technology immediately began to circulate. However, the rumours had no effect on the sales, and the videos of onboard systems and weapons tests provided by the Sentinels impressed the public.
