Hunter X

First ship on my .21 sandbox save was the Ascendant I. This was soon replaced by a variety of constellation/mythical names, with the Orion series (14 models aimed at reaching orbit around Kerbin) and the Artemis series (6 models designed for Munar orbit and/or landing) being the most prominent. First ship on my new .22 career mode save was the Flying Brick series, which somehow managed to accumulate three different iterations before getting enough tech upgrades to reach orbit and being replaced by the Orbiter series (although my latest Orbiter model managed to leave Jeb stuck in orbit around Kerbin before a daring EVA attempt managed to decelerate the craft just enough to bring it into the atmosphere and eventually land after several days of aerobraking). Odds are future ships will follow a similar naming convention to my .21 save.
