"Gentlemen! The time to test us has arrived!" the factory manager, just back from a meeting, called out loudly to the few engineers awaiting him as he entered.
Their factory was a cannon factory of the Great Tang Empire, mostly producing 75mm caliber long-barreled tank guns.
It was the same 75mm caliber tank gun mounted on the Panther Tank, now also being widely used on the No. 4 Assault Gun.
Unfortunately, the latest Model 59 Tank used a 105mm caliber tank gun, which was manufactured by a dedicated factory and wasn't much related to their factory.
The factory system of the Tang Empire was somewhat different from that in the normal world: a typical heavy industrial factory elsewhere would continue its legacy, upgrading equipment and transitioning from producing old products to new products, meeting market demands.
