USS Skywatcher
1945 Guardian-class radar picket ship
USS Skywatcher (YAGR/AGR-3) was a Guardian-class radar picket ship, converted from a Liberty Ship, acquired by the US Navy in 1954. She was converted into a radar picket ship and assigned to radar picket duty in the North Atlantic Ocean as part of the Distant Early Warning Line.
Construction
Skywatcher (YAGR-3) was laid down on 30 November 1944, under a Maritime Commission (MARCOM) contract, MC hull 2337, as the Liberty Ship Rafael R. Rivera, by J.A. Jones Construction, Panama City, Florida. She was launched on 16 January 1945; sponsored by Mrs. Evelyn Anderson; and delivered 25 June 1945, to the States Marine Corporation.
Service history
Seacowboys
In 1946, after World War II, Rafael R. Rivera was converted to a livestock ship, also called a cowboy ship. From 1945 to 1947, the United Nations Relief and Rehabilitation Administration and the Brethren Service Committee of the Church of the Brethren sent livestock to war-torn countries. These "seagoing cowboys" made about 360 trips on 73 different ships. The Heifers for Relief project was started by the Church of the Brethren in 1942; in 1953, this became Heifer International. Rafael R Rivera was one of these ships, known as cowboy ships, as she moved livestock across the Atlantic Ocean.
This brief starts where responsible research should: with the source description of “USS Skywatcher” as 1945 Guardian-class radar picket ship. Everything that follows is an evidence route, not borrowed authority.
Why this record matters
The subject matters to the general reference register because the source frames it as 1945 Guardian-class radar picket ship. Its deeper value depends on whether names, dates, institutions and citations support that framing.
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 Aug 14, 2026. The linked authority identifier is Q7874207. None of the 0 selected statements returned an explicit reference. The first chronological checks are 1954, 1944, 1945 and 1946.
The absence of detail may reflect summary conventions rather than a lack of surviving documentation. 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.
