Ves faced numerous obstacles when it came to pushing the Final Drive Project.
They questioned its timing. The Design Department was too busy to divert time and resources to a side project of questionable usefulness.
They questioned its necessity. Why design a mech that was nothing more than a suicide vessel with a few added parts that were unique to Carmine mechs?
They questioned its value. If a population of a planet that had come under the threat of annihilation wanted to convert local resources into a means to strike back at the native aliens one last time, they could easily resort to more efficient alternatives such as plain surface-to-orbit rockets or fixed gun turrets.
The skeptics all raised good points, but their perspective was not as complete as that of Ves.
