Ghostbuddy:Human Air vehicles (Bombers) : Longsword ,Broad sword , and Shortsword . All names of classifications of swords.
1. Broadsword is not an official name of anything.
2. Longsword is the class of ship (as in space)-based fighters. It is not the name of the ships, even though they are now seemingly interchangable - blame Halo 1's ending.
3. The Longswords are therefore NOT in the bomberclassification, hence nullifying your catgorization of Shortsword.
3. Even if Longsword were a valid name, and also in the bomber category, using "shortsword" as the name/title of another such vessel would be ... unimaginative at best.
