Though you would think GuP is prime material for shipping, and my yuri glasses are not the thinnest around, I never really felt it from most of the cast. Not that it is a negative, seeing as the sensha-do action itself is so entertaining. When it comes to Yukarin and Nishizumi-dono though---
squeals uncontrollably
Yeah, that.
I don't think you're the only one who thinks like that. Seeing as GuP's fanfiction sub-section is generally filled with het works in which Oorai becomes a Co-ed school, usually they also try to add in something like Tankery, only with planes or infantry instead. It's really just an excuse to get their OCs to hang out with the main characters though, so they can start shipping them together.
