When a SCUL pilot christens their first ship, they must choose a three letter prefix to all the ships they build henceforth. The christening ritual can vary, but typically the builder presents their ship at the launch pad, says a few words about how it was build, thanks those who helped in the process, then pours their preferred liquid over the ship. Pilot usually yell "ON THE SEAT!", but the builder has the option to ignore the request. Once the builder completes their first successful mission on their new ship, they receive a builder medal.
