There's no big rush to get to that level- those they now have can strike N. America from the SC Sea & Hainan area, protected by CV/Ns, PLA/NAF, & surface ships. They can even sail up & down on the Yangtze river & 2 big lakes connected to it, camouflaged on the top as a barge. In some places, they could even dive with room to spare:When China gets a SSBN with Borei's capabilities you let me know.
Even before the river was inundated, its depth in the gorges was considerable, increasing to between 500 and 600 feet (150 and 180 metres) and giving the Yangtze the greatest depths of any river in the world. ...
At the edge of the Lake Liangzi plain the Yangtze widens markedly, the course of its stream wandering in the form of a large loop. The width of the river is up to 2,600 feet (800 metres), the depth is more than 100 feet (30 metres), ..
The width of the river increases at this point to between 3,000 and 6,000 feet (900 and 1,800 metres), and the depth in places approaches 100 feet.
