Their military weapons are a joke to begin with.
Aircraft carrier:
Newest and latest is a diesel powered. It needs 48 hours to heat up the engine. It needed refuelling every 4 days. Furthermore, it needs another 2 hours just to accelerate.
Satellite Power :
Their Beidou is a complete joke. It looks good in China when you see the DIDI drivers used it. But in actual fact, comes to military used it F up. Recently, a ocean going fish trawling ship sunk in the middle of Indian Ocean. They could not even locate it. Their Beidou is not working. The military can't even locate where the location is. Because the fishing ship is a multinational fish trawler, it has a other national on board. So Australia and other country has to chip in and help. The Chinese came in 2 days later when it is found.
