This month, a photo of USS Black Hawk during minesweeping operations in the North Sea. On the starboard side are two U.S. minesweepers, USS Penguin with hull mark PD, and another marked PK which according to this page is USS Seagull, although I have not seen a photo where it's clearly shown.
On the port side are at least two chasers. The outer chaser is SC 356, and I think the inner one is SC 48. SC 356 was built at College Point Boat in New York, and served at Plymouth and Queenstown during the war. SC 48 was built at New York Naval Shipyard, and also served at Plymouth and Queenstown.
You can see a larger version of this photo along with some other minesweeper images on this page.
Hope you are enjoying the spring.
