Unless the unit has CASE, or is packing a Gauss rifle or improved heavy lasers (in which case one would worry about the weapon), or perhaps has an IS XL engine. Though it's not smart for Gundam to pick a fight with a universe that has vastly superior space based mobility than it dose (as even a "slow" and under fueled Aerospace fighter has over 70km/s of Delta V and can accelerate at 3G)

I was just making a joke from not-so fond memories of of ammo critical hits subdividing precious battlemechs in unpleasant ways.
None the less 17ish tons carrying some 800 rounds of ammo between the two pods should be more than enough for the Xeku Eins, this leaves 32ish tons for the fuel and weapons.
Good, it seems like something workable now.
Edit: I wonder if I should post my B-tech ASF performance stats I worked up.
Well, it might help as an example of "how things work" concerning propulsion & energy consumption in space for those of us who didn't make it past basic physics.
