I had a hand in placing THAAD in SK and Guam and still have numerous contacts in the area. I travel to the region regularly for a defense contractor on mundane stuff but that is not the purpose of this post.
I received a call yesterday from a .mil source that said a chinese frigate tried to ram a US destroyer. I hadn't seen anything on the news so took it with a grain of salt. This evening I received three contacts that each provided the following with some overlapping information:
Four days ago in the sea of Japan a US destroyer found it was being followed by two Chinese subs believed to be type 39s. Two attack submarines were tasked to assist the destroyer along with a Japanese frigate and it was typical cat and mouse. However, yesterday a Chinese frigate along with over a dozen large fishing boats attempted to block navigation of the US destroyer, inciting a bow scrape between the frigate and destroyer. At this time one of the two type 39s opened torpedo doors which caused the destroyer to engage and sink it.
China is furious and is threatening to sink any US warship that enters the SCS area without warning.
