This navy “mystery” comes on June 2, 2021, the 153rd day of the year, which is the 17th triangular number. As per usual, gematria tells the tale. Keep in mind the date can be written 6/2, like 62.
–Navy = 62 / 17
–Sink = 17

And notice it is another “incident” with Iran’s navy in the Gulf of Oman.
-Gulf of Oman = 47
–News = 47
