So all it needs is a few plates to cover the barrel. No light!
On another note: The Type One is a subflight unit like Justice's Fantum(sans the cool wing beam blades).
But I'm envisioning the Type One being able to mount onto the Minerva as a backpack thruster unit without having the Minerva jump off and re-mounting(In other words, mid-flight gattai! style) the Type One on its back...
