Source-derived summary

USS Cubera (SS-347), a Balao-class submarine, was a ship of the United States Navy named for the cubera, a large fish of the snapper family found in the West Indies.

Cubera (SS-347) was launched 17 June 1945 by Electric Boat Co., Groton, Conn.; sponsored by Mrs. J. Taber; commissioned 19 December 1945 and reported to the Atlantic Fleet.

After shakedown training off New London, Cubera arrived at Key West, Fla., 19 March 1946. She tested sonar equipment, provided services to experimental antisubmarine warfare development projects in the Florida Straits, and joined in fleet exercises until 4 July 1947 when she sailed to Philadelphia Naval Shipyard for an extensive GUPPY II modernization.

Returning to Key West 9 March 1948 Cubera continued to operate locally out of this port, as well as taking part in fleet exercises in the Caribbean and Atlantic until 3 July 1952 when she arrived at Norfolk, her new home port.

Cubera appeared in Ray Harryhausen's It Came from Beneath the Sea (1955), playing an "atomic sub" used to dispatch the film's giant octopus.

Through 1957 Cubera conducted local operations, and participated in fleet exercises in the Caribbean, as well as cruising to Sydney, Nova Scotia, in June 1955. During 1959 and 1960, she was assigned to Task Force Alfa, a force conducting constant experiments to improve antisubmarine warfare techniques. With this group she cruised the western Atlantic from Nova Scotia to Bermuda.

Editorial analysis

Why this record matters

“USS Cubera” is worth following because a concise public description often conceals a longer documentary argument. Here, Cubera, Balao-class and submarine provides the most credible route into that argument.

Evidence profile

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 Dec 12, 2025. The linked authority identifier is Q3267965. None of the 0 selected statements returned an explicit reference. The first chronological checks are 1945, 1946, 1947 and 1948.

Critical limits

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.
