"Ah, yes, I have read that file," Takao Hiyashi said. "The modified engines were a very creative and inspired approach. I believe we're going to use a version of those in our future heavy transports, even. Yokohama really has great engineers."
He continued, "It should be able to fly across the border without any problems legally right now, as it's just the modified transport. If you wanted advanced hull plating, you'd probably have to get that installed at your destination. Samura is happy to sell anyone with correct papers ship hull panels, though you'll need your own engineers."
After handing the man a brochure with the publicly available parts, he said, "Unfortunately, we are unable to help with weapons of any sort. That's beyond our scope. Only the government can deal with them, whether through our new elected officials, the KNF, the State Police, or our various intelligence and security agencies."
"Rumor has it though," Takao rubbed his chin and said, "that the Renzu Corporation's shipyard in Oita does all manner of private work to order. We at Samura are focused on corporate dealings, of course. You may want to speak with them. The modified Big Dragon, which I've taken to calling the Biggest Dragon, is more than structurally stable enough to fly wherever using transport-class weaponry."
Takao Hiyashi bowed again to the potential customer.
