lol, this is a funny article.
US Naval Power is not just about the US Navy (even so, it have suggested way LESS ship than it should be) US Naval Power is very clearly defined, unlike PLAN, which is one stop for all, Total US Naval Power should be counted all element from US Navy (USS ship) for major off shore combatant, US Naval Service (USNS Ship) for support such as mine sweeping and logistic and US Coast Guard (USCG) ships for coastal support. On the other hand, every ship commissioned to PLA Naval Power were assigned into PLAN.
If you look at the ship disparity listed, you will see that Chinese is behind is large surface ships and aircraft carrier (Also carrier for US should be 22 instead of 11, 11 super carrier but there will be 11 America Class,) there are, US Navy have less small surface combatant. Also Amphibious Warfare ship is missing (Provided by 12 San Antonio Class, 12 Spearhead Class EPF)
The problem is that US Navy themselves does not operate the type (Small Warfare ship) which is the job for 283 USCG cutters (which serves as both Frigate and Mine Destroyer role) US Navy only tasked with off shore engagement. Every US Navy warfare are therefore, Ocean Going.
On the other hand, Majority of US Navy ship is forward deployed, which mean they were based OUTSIDE continental US, 3rd Fleet is based in Hawaii, 7th Fleet is based in Japan, 5th Fleet is based in Rota Spain, 4th Fleet is based in Puerto Rico. While almost 100% of USCG ship is based in Continental US. China, by definition only have 4 deep base and 11 coastal base, cannot literally have supported more number of ship than the whole US Naval Force.
In all, if you put all US Naval Power together (USN + USNS + USCGS) you are looking at around 800 ships altogether with USN about 320 Combatant (Aircraft Carrier, Amphibious ship, Destroyer, Cruiser, Corvette and PB), USNS about 180 Amphibious, Mine Laying and Troop support and USCG about 280 Cutter.
The guy who wrote this piece of crap article either do not understand US Naval Structure or intentionally misleading the reader..
