Human Events estimated that by 2025, Chinese attack submarines will outnumber U.S. submarines in the Pacific by five to one. Chinese military modernization has accelerated since the mid-to-late 1990s in response to central leadership demands to develop military options against Taiwan scenarios. China is likely to continue making large investments in high-end, asymmetric military capabilities, emphasizing electronic and cyber-warfare; counter-space operations; ballistic and cruise missiles; advanced integrated air defense systems; next generation torpedoes; advanced submarines; strategic nuclear strike from modern, sophisticated land and sea-based systems; and theater unmanned aerial vehicles. The People’s Liberation Army Navy (PLAN) submarine modernization program oversaw the acquisition of four modern Russian-built KILO subs, including the stealthy Type-636. Orders for eight more are on the books, with the first new boats
to be delivered this month. China has also increased production -- to 2.5 boats per year -- of the Song-class diesel-electric submarine. China is also testing a new diesel-electric that the defense intelligence community has designated the Yuan. The Yuan is heavily inspired by Russian designs, including anechoic tile coatings and a super-quiet seven-blade screw.
