USS SC-151
SC-1-class submarine chaser

USS SC-151, prior to July 1920 known as USS Submarine Chaser No. 151 or USS S.C. 151, was an SC-1-class submarine chaser built for the United States Navy during World War I. She operated as part of the Otranto Barrage during the war.
After World War I, the former SC-151 became the fishing boat Usona. She returned to U.S. Navy service during World War II as the yard patrol boat USS YP-191. After World War II, she again became a fishing boat, named Sea Queen III.
Construction and commissioning
SC-151 was a wooden-hulled 110-foot (34 m) submarine chaser built by the Gibbs Gas Engine Company at Jacksonville, Florida. She was commissioned at the Charleston Navy Yard in Charleston, South Carolina, on 14 December 1917 as USS Submarine Chaser No. 151, abbreviated at the time as USS S.C. 151.
Service history
World War I
Assigned to operate as part of the Otranto Barrage in the Strait of Otranto between Brindisi, Italy, and Corfu, S.C. 151 arrived at Corfu on 5 June 1918 as part of a convoy consisting of 21 submarine chasers and their mother ship, the former collier and survey ship USS Leonidas. Operating from Base 25, a newly constructed U.S. Navy submarine chaser base in a bay on the east side of Corfu northwest of the city of Corfu, she was assigned along with the submarine chasers USS S.C. 94 and USS S.C. 227 to Unit F of Squadron 1.
On the evening of 18 June 1918, Unit F was on an antisubmarine patrol in the Strait of Otranto when it became involved in a friendly fire incident.

Why this record matters
“USS SC-151” is worth following because a concise public description often conceals a longer documentary argument. Here, SC-151, SC-1-class and submarine provides the most credible route into that argument.
The citation trail is more important than the brevity of the summary: it shows where individual claims can be examined in context. The source revision retrieved here is dated Mar 5, 2026. The linked authority identifier is Q117379183. None of the 0 selected statements returned an explicit reference. The first chronological checks are 1920, 1917 and 1918.
A concise general-reference account can conceal disagreements about scope, terminology or the weight assigned to individual sources. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
