Technology & Combat Characteristics
The Temptation class was used as a mid range shuttle for use between colonies and for ascent to orbit. The shuttle would seem to lack substantial thrust even with boosters as one such vessel launched in the École du Ciel manga with a booster module larger than the shuttle itself from a Garuda-Class Transport Aircraft, this implying it already needed to be at high altitude.
The Valentine was a Temptation class shuttle employed by the Earth Federation and used to transport the students of École du Ciel to space. The Valentine was seen only briefly when ferrying the École du Ciel students from a Garuda to the Ericsson. It performed this through the use of a booster system.
