"What is this?" Vice Director Fu stared at the long cannon barrel on the blueprint in silence. For the first time, an emotion resembling expression flickered across the otherwise unaffected face of the "turtle spirit."
"It's a cannon, but somehow this thing looks even thicker than the field artillery used by the army." Director Zheng scrutinized the specifications on the blueprint and clicked his tongue. "Good heavens, 150 mm, 45-caliber length, and it's smoothbore."
"A 150 mm smoothbore cannon isn't a problem for us. We can make it, easily even. Some folks are building monstrous 70-caliber length guns with a 150 mm bore diameter. In the realm of fortress artillery, this size isn't considered massive, but in field artillery, this would definitely qualify as heavy artillery. The army has a 200 mm variant, but that's vehicle-mounted. If it's brought into the skies, how would we handle its weight and ammunition loading mechanism?"
