Kotlin provides some inspiration for China's Luda class, with selected features adapted to Chinese requirements. Its systems occupy discrete areas so that replacing one installation can be confined to a particular part of the ship. This arrangement helps explain how a gun-era hull can accept missile conversions. Gorshkov had supported upgradeability while involved with the design before becoming head of the navy. The advantages for refitting leave separate questions about survivability and long-term operation, which remain unresolved here.

Kotlin system layout eases upgrades and influences Luda
Separate system areas make Kotlin easier to refit, while China's Luda class adapts selected features of the Soviet design.
