[Strike Witch]

During its conceptual phase, the series was titled Freedom Fighter Gunboy, or simply Gunboy for the gun the robot was armed with, and the primary target demographic were shōnen (boys). In the early production stages, there were numerous references to the word "freedom": the White Base was originally "Freedom's Fortress", the Core Fighter was the "Freedom Wing", and the Gunperry was the "Freedom Cruiser". The Yatate team combined the English word "gun" with the last syllable of the word "freedom" to form the name Gundom. Tomino then changed it to the current title, suggesting that Gundam signified a powerful unit wielding a gun powerful enough to hold back enemies, like a hydroelectric dam holding back floods.

Basically, "a warrior with a Gun who is strong enough to hold back enemies like a dam."
