The progress on warship modification is surprisingly faster.
The original fleet size of nearly four thousand armed battleships has been compressed to exactly two thousand.
Although many pieces of equipment have been added and many core components' performance parameters have been altered, the internal space of the warships hasn't expanded; rather, it has reduced somewhat.
The previous recreational and entertainment daily living spaces have all been dismantled and rebuilt into military capability-related modules. The crew capacity of each ship has increased to sixty thousand, with average living space reduced by a full 80%, changing from single rooms to shared dormitories. Ren Zhong and Zheng Tian don't see this as a problem.
The original armed battleships had to reserve so much living space primarily because their voyages were too long; the warships needed to have residential functions so people could live on them generation after generation without mental distress.
