SC 309 and SC 310 served in Alaskan waters, during and after the war. A short New York Times article dated 21 June 1919 reports the following: "JUNEAU, Alaska, June 21. - Submarine Chaser SC 310 was ordered by Governor Thomas Riggs, Jr., to the vicinity of Yukutat Village to quell a reported native uprising today..."
These are two photos of SC 310 in Alaska.
