Members of the US Coast Guard Auxiliary anti-submarine forces, colloquially referred to as the “Corsair Fleet”
1938 The newly established “Coast Guard Reserve” (what would become the Coast Guard Auxiliary) enrolled its first members.

1943 Patrol Squadron 6 (VP-6 CG) was officially established. This was an all Coast Guard unit. Its home base was at Narsarssuak, Greenland, code name Bluie West-One. It had nine PBY-5As assigned. CDR Donald B. MacDiarmid, USCG, was the first commanding officer. As additional PBYs became available, the unit’s area of operation expanded and detachments were established in Argentia, Newfoundland and Reykjavik, Iceland, furnishing air cover for Navy and Coast Guard vessels. Hundreds of rescue operations and aerial combat patrols were carried out during the 27 months the squadron was in operation.
1969 For extreme and heroic daring on the morning of October 5, 1969, while on authorized leave, Coast Guardsman James P. Grier rescued two persons and attempted to rescue a third from drowning in the waters of the Atlantic Ocean at Rockport Harbor, MA. For his actions the Coast Guard awarded Petty Officer Grier a Gold Life-Saving Medal.

I have just discovered USCGC Northland (WPG-49).
I have a new favourite ship…………
@X, she did have quite a career.
USCGC Northland (WPG-49) – Wikipedia
There is a picture of her under full sail on Wikipedia.
When that picture first flicked across my screen I thought for a second it was a Hamilton.
Amazing ship.

“Your photo caption “Members of the US Coast Guard Auxiliary anti-submarine forces, colloquially referred to as the “Corsair Fleet”, is historically inaccurate. The Coastal Picket Force vessels were initially crewed by members of the Coast Guard Reserve (Temporary), aka Temporary Reservist or TRs. Many TRs, but not all, were recruited from the Auxiliary. You might find these two essays insightful. https://media.defense.gov/…/-1/-1/0/DESH-KEYES-MOHAWK.PDF https://media.defense.gov/…/DESH_SUBMARINES_AND_SAILING…
I have added these two articles to my Heritage page.
