china needs to shift their strategy to 2x building more fighter jets and submarine. U.S seems to be very focused on sinking China's warship.
Fighter jets are better imo. They provide air superiority and less dangerous compared to a warship. Warship requires hundreds of crewmen to operate which is risky. Fighter jet only one guy. It can shoot all of their ammo and return back to base easier than a navy ship.
Your logic is flawed. Firstly, as if the US isn't also focusing on finding ways to shoot down Chinese fighters and hunting down Chinese submarines lmao.
Then, there is this fundamental fact where no equipment and platform works alone anymore. Pretty much all of them are parts and components of integrated systems of systems of warfare today and into the future.
Moreover, without (more than) sufficient number of capable surface warships - Who's going to escort amphibious assault forces to their destination landing beaches during Operation AR? Who's going to blockade certain islands to prevent enemy reinforcements to resupply and relieve enemy forces trapped on those islands? And who's going to guard the operational area against foreign/enemy military intervention on the high seas?
Furthermore, unlike the (CON)US which boasted three island chains spanning the entire Pacific, China has none to speak of. This means many of the major Chinese population, economic and industrial centers situated along and near her coastlines are exposed to enemy action coming from the WestPac, especially considering that many hundreds of millions of the Chinese populace do live within 1000 kilometers of the Chinese coastline. Without (more than) sufficient number of capable surface warships to fill the 1IC and 2IC, how is China going to be able to extend her shield outwards into the sea in order to defend her most populous and performing regions from enemy warplane and missile attacks during war, before those warplanes and missiles enters Chinese territorial airspace?
Last but not least - A submarine can house officers and crew in the many tens (for SSKs) if not more than 100 (for SSNs and SSBNs). If anything, while at least some number of officers and crew of a surface warship can escape on lifeboats when the warship goes down - More often than not, a submarine gets sunk with all hands lost.
