The second USS Menhaden (SS-377) was United States Navy Balao-class submarine. Launched in 1944, she operated out of Pearl Harbor until 1946, then continued in use out of various ports in the Pacific until the 1970s. She was then decommissioned and re-fitted as a remotely controlled, unmanned acoustic test vehicle known as the "Yellow Submarine", until she was scrapped in 1988.
