Here at LSOZI, we take off every Wednesday for a look at the old steam/diesel navies of the 1833-1954 period and will profile a different ship each week. These ships have a life, a tale all their own, which sometimes takes them to the strangest places. – Christopher Eger
Warship Wednesday, Oct. 11, 2023: Sink Em All
Above we see the Gato-class fleet boat USS Wahoo (SS-238) at Pearl Harbor, soon after the end of her Third war patrol, circa 7 February 1943. Her skipper, LCDR Dudley W. Morton, who would count four Navy Crosses in the war, is on the open bridge, in right-center while the officer to the left could be XO, LT Richard H. O’Kane, who would go on to earn the MoH.
If you will observe, there is a broom lashed to the periscope head, indicating a “clean sweep” of enemy targets encountered as well as an aloft pennant bearing the slogan “Shoot the Sunza Bitches” and eight small flags, representing claimed sinkings of two Japanese warships and six merchant vessels. What is not in the picture is the forward radar mast, which has been brushed out by wartime censors.
Just six months after this image was snapped, Wahoo would be broken on the bottom of the La Pérouse Strait, lost exactly 80 years ago today.
The Gatos
The 77 Gatos were cranked out by four shipyards from 1940 to 1944 for the U.S. Navy, they were impressive 311-foot-long fleet boats, diesel-electric submarines capable of extended operations in the far reaches of the Pacific. Able to swim an impressive 11,000 nautical miles on their economical power plant while still having room for 24 (often cranky) torpedoes. A 3-inch deck gun served for surface action in poking holes in vessels deemed not worth a torpedo while a few .50 and .30-cal machine guns provided the illusion of an anti-aircraft armament.
Developed from the Tambor-class submarines, they were the first fleet boats able to plumb to 300 feet test depth, then the deepest that U.S. Navy submersibles were rated.
Meet Wahoo
Our subject is the first U.S. Navy warship– and probably the first in any fleet– named for the wahoo, a beautiful (and delicious) sport fish in the Gulf of Mexico and the Caribbean.
Laid down a half-year prior to Pearl Harbor on 28 June 1941 by the Mare Island Navy Yard in Vallejo, California, Wahoo was launched on Valentine’s Day 1942– a sweetheart gift to the Japanese Navy.
She was commissioned on 15 May 1942, LCDR Marvin Granville Kennedy (USNA 1930) in command.
Kennedy, who had served in a mix of both surface warfare and submarine billets, was XO of the huge “V-boat” USS Narwhal (SS-167) at the beginning of the war, aboard her when her gunners opened up at incoming Japanese planes over Pearl Harbor. Wahoo was his first command, and he would be at her attack periscope for her first two patrols.
The new boat and green crew spent the next three months fitting out and conducting initial training along the California coast then, after a post-shakedown repair at Mare Island, left headed for Hawaii on 12 August.
War!
First War Patrol (23 Aug 1942, Pearl Harbor-17 Oct 1942, Pearl Harbor)
Her patrolling career began in August 1942 in the Carolines. On this patrol, Wahoo claimed the sinking of a freighter not confirmed by post-war review. Other attacks were spoiled by faulty torpedoes, a common refrain in the U.S. Submarine Force in the Pacific at this time.
Second War Patrol (8 Nov 1942, Pearl Harbor- 26 Dec 1942, Brisbane)
Her second patrol was in the Solomons, where she sank a freighter, the Japanese collier Kamoi Maru (5355 GRT) off Buin, on 10 December. Following this patrol, Kennedy, who earned a Silver Star for sinking the enemy collier, left the boat and joined the staff of Commander Service Force, Southwest Pacific.
Replacing the 37-year-old Kennedy was an old classmate of his from Annapolis, Florida-born LCDR Dudley Walker Morton, better known by his Academy nickname of “Mushmouth” or, just the simpler “Mush.” Morton had previously commanded the smaller boats USS R-5 (SS-82) and USS Dolphin (SS-169), then sailed as XO under Kennedy on Wahoo’s Second War Patrol. The new XO would be LT Richard Hetherington “Dick” O’Kane (USNA 1934)
It seemed like, in Wahoo’s case, that the third time was the charm when it came to patrols.
Third War Patrol (16 Jan 1943, Brisbane-7 Feb 1943, Pearl Harbor)
Wahoo conducted her third patrol from Australia through New Guinea to the Palau area of the Japanese-annexed Caroline Islands. She steamed 6,454 miles and expanded all her torpedoes.
Prior to leaving Australia, Morton reportedly told the crew:
“Wahoo is expendable. We will take every reasonable precaution, but our mission is to sink enemy shipping. . . . Now, if anyone doesn’t want to go along under these conditions, just see the yeoman. I am giving him verbal authority now to transfer anyone who is not a volunteer. . . . Nothing will ever be said about you remaining in Brisbane.”
She sank the destroyer Harusame on 24 January off Wewak, New Guinea.
Two days later chased down a four-ship convoy included sinking the large Japanese army cargo ships Buyo Maru (5447 GRT) and Fukuei Maru No.2 (1901 GRT) along with damaging the tanker Pacific Maru (5872 GRT).
Fourth War Patrol (23 Feb 1943, Pearl Harbor- 6 Apr 1943, Midway)
For her fourth patrol, Wahoo went to the Yellow Sea west of Korea and just ran amok, only returning after she expended all 24 of her torpedoes.
She sank the cargo ship Zogen Maru (1428 GRT) and damaged the freighter Kowa Maru (3217 GRT) east of Dairen on 19 March, sank the cargo ships Hozan Maru (2260 GRT) and Nittsu Maru (2183 GRT) on 21 March, on 23 March sent the cargo ships Teisho Maru (9849 GRT) and Takaosan Maru (2076 GRT) via torpedoes then finished up with the smaller Satsuki Maru (830 GRT) via gunfire.
She finished her run with the cable ship Yamabato Maru (2256 GRT) south of Kyushu, Japan, and two sampans.
Her claimed kills were a bit higher.
Fifth War Patrol (25 Apr 1943, Midway-21 May 1943, Pearl Harbor)
Going to the Kurile chain for her fifth patrol, Wahoo sank two confirmed freighters– Takao Maru (3204 GRT) and Jimmu Maru (1912 GRT) — off Kone Zaki, north-eastern Honshu on 9 May. She ended, again, with no torpedoes left, having steamed 6,828 nm.
Her 5th war patrol claims:
Following the end of the patrol, she was sent back to Mare Island for a much-needed overhaul, carrying almost 30,000 miles on her diesels and the effects of multiple depth charging runs from the Empire.
A series of photographs from the Bureau of Ships Collection in the U.S. National Archives remains to document her condition at this stage of her hard life.
Sixth War Patrol (2 Aug 1943, Pearl Harbor-29 Aug 1943, Pearl Harbor)
The sixth patrol of Wahoo, conducted in the target-rich Japan Sea, suffered from defective Mark 14 steam torpedoes. None of the 10 fish fired in nine attacks on enemy merchantmen resulted in a torpedo hit but she was able to sink a trio of sampans with surface gunfire.
The patrol reports of the failed attacks are crushing:
She made good in surface actions against fishing boats– at least her guns worked!
Across her first six patrols, she claimed 27 ships sunk, totaling 119,100 tons, and damaged two more, making 24,900 tons. Of these, most were on Mush Morton’s three patrols, in which Wahoo had sunk a claimed total of 93,281 tons of shipping in only 25 patrol days.
Leaving the boat was her talented XO, Dick O’Kane, who was called up to the big leagues and rewarded with a command of his own, the Balao-class boat USS Tang (SS-306).
Seventh (Last) War Patrol (9 Sep 1943, Pearl Harbor-lost on/about 11 October 1943, in La Perouse Strait)
Sent back to the Sea of Japan– armed with the new Mark 18 electric torpedo, instead of the hated Mark 14s– Wahoo was the only Allied warship active there when the fishing vessel Hokusei Maru (1394 GRT) was lost west of the Kuril Islands on 21 September, the gunboat Taiko Maru (2958 GRT) west of the Tsugaru Strait on 25 September, the freighter Masaki Maru No.2 (1238 GRT) in the Sea of Japan east of Hungnam on 29 September, the transport Konron Maru (7908 GRT) in Tsushima Straits on 5 October, the cargo ship Kanko Maru (1283 GRT) off Korea on 6 October, and the cargo ship Hankow Maru (2995 GRT) off the Oga Peninsula on 9 October. Good hunting!
However, the hunter became the hunted, and Wahoo never made it back to Pearl, with her war flags flying and crew beaming. Postwar, it was determined that Japanese E13A1 “Jake” floatplanes out of Wakkanai, supporting the submarine chasers Ch-15 and Ch-43, and minesweeper Wa-18, following up on the sighting of a strange submarine by the coast artillery battery on Soya Misaki, responded and chased Wahoo to the bottom of the in La Perouse Strait on the morning of 11 October 1943.
The wreck, found in 2004 resting 12 miles off the northeast coast of Hokkaido in the middle of the strait, confirms the place and cause of her destruction.
She was lost with all 80 hands. Declared officially dead in 1946, all are memorialized at the National Memorial Cemetery of the Pacific (Punchbowl) on the Court of the Missing.
Wahoo earned six battle stars for World War II service.

In all, “Mush” Morton would be awarded four Navy Crosses, the final one posthumously.
Epilogue
The fighting spirit of Mush Morton and the Mighty Wahoo would endure long after they were gone.
Wahoo’s plans, deck logs, and patrol reports (1-6) are digitized in the National Archives.
Wahoo’s ship’s bell and commissioning pennant, which had been stored at Pearl Harbor while she was on her wartime service, are preserved at the USS Bowfin Submarine Museum & Park along with a marker honoring her.
In 1995, the Wahoo Peace Memorial cenotaph was dedicated in Japan at Cape Soya near Wakkanai overlooking the La Perouse Strait where the submarine was lost.
The Forrest Sherman-class destroyer USS Morton (DD-948) was named in honor of Wahoo’s most famous skipper. Built at Ingalls and nicknamed “The Saltiest Ship in the Fleet!” due to the obvious Morton’s Salt reference, she served until 1982, chalking up several stints off Vietnam including close-in NGF support and Sea Dragon operations off North Vietnam.
Dick O’Kane, who according to the NHHC took part in more successful submarine attacks than any other American officer across five patrols with Wahoo and five more in command of Tang, earned the Medal of Honor, three Navy Crosses, three Silver Stars, and the Legion of Merit with Combat “V.” After Tang suffered a sinking via a runaway torpedo in the Formosa Sea, O’Kane and four of his surviving crewmen were “rescued” by the Japanese. After surviving the war at just 88 pounds and testifying as a witness at the Japanese War Crime trials, he returned to duty, retiring in 1957 as a rear admiral after having punched tickets as COMSUBDIV 32 and as the Officer in Charge of the Sub School at New London.
O’Kane’s legacy lives on. The USS O’Kane (DDG-73), a Navy destroyer, was commissioned in Pearl Harbor in 1999 and continues to serve based out of San Diego. The former rear admiral’s Medal of Honor is kept at the USS Bowfin Submarine Museum and Park in Honolulu. Further, his cribbage board, which he presented to the second Tang (SS 563) in 1957, is handed down to each oldest fast-attack submarine in the Pacific Fleet. Since that boat retired, it has been handed down to USS Kamehameha (SSBN 642), USS Parche (SSN 683), USS Los Angeles (SSN 688), USS Bremerton (SSN 698), USS Olympia (SSN 717) and now USS Chicago (SSN 721).
Wahoo’s legacy lived on as well. Two different Tench class submarines (SS-516 and then SS-518) were to have carried the name but never made it into service. A Tang-class boat, SS-565, did, however, in 1952. She served until 1980, one of the final diesel boats on active duty with the U.S. Navy.
A planned Block 5 Virginia-class submarine, SSN-806, will be the third USS Wahoo commissioned. Likewise, her sister SSN-805 will be the third USS Tang.
Ships are more than steel
and wood
And heart of burning coal,
For those who sail upon
them know
That some ships have a
soul.
