Heavyweight Match

Posted on by Leave a comment

A special Warship Wednesday today. A moment frozen in time, some 80 years ago today.

The afternoon of 6 August 1945.

President Harry S. Truman and his party aboard the Northampton-class “medium-heavy” cruiser USS Augusta (CA-31) for the return trip from the Berlin (Potsdam) Conference are seen watching boxing bouts. 

The bespectacled Missouri National Guard artillery colonel and Great War veteran is seen ringside, wearing a driving (newsboy) cap. He is flanked by Secretary of State James F. Byrnes (left) and Fleet Admiral William D. Leahy (right). Note the crew in crisp summer whites and an obsolete Curtiss SOC-1 Seagull floatplane on the catapult above.

Laid down on 18 December 1924 as a “treaty” light cruiser, Augusta was nominally a 9,000-ton ship with a veneer of armor plate (as thin as 0.75 inches on the turrets, only 1.25 inches on the Conning Tower, and a maximum belt of 3.75 inches). She was later reclassified as a heavy cruiser because she and her sisters carried 8″/55 guns.

Serving with the Asiatic Fleet pre-war, a 1940 refit saw her as one of the first dozen warships to receive the early RCA CXAM-1 radar, and she was sent to the Atlantic in 1941 where ADM King used her as a flagship and she was pressed into service as FDR’s flagship for the Newfoundland conference, tied up next to the much larger battleship HMS Prince of Wales which had carried Churchill to Argentia.

Very active during WWII, she remained a ship that “stars fell upon,” carrying Patton during the Torch Landings in North Africa, Bradley during Overlord off Normandy, Chidlaw to Corsica, and hosted Forrestal during the Dragoon landings in Southern France (during which she also fired all but the last 50 rounds of 8-inch in her magazine during NGFS ashore).

Augusta was further key to history as Truman was on the ship when he got the news that Hiroshima had been hit by the first atomic bomb (Little Boy) used in warfare, and held the first press conference on the matter with embarked war correspondents. 

The news hit right before the above boxing match.

Besides all the American “who’s who,” Augusta also hosted King George VI at least twice while in Europe for the conference.

She put into Norfolk on 7 August 1945 to disembark Truman and company, spent several months in “Magic Carpet” operations, bringing GIs home from Europe, and decommissioned on 16 July 1946.

Augusta was lucky; three of her five sisters– Northampton, Chicago, and Houston— were sunk in the Pacific during the war.

Laid up in mothballs at Philadelphia while Truman was still in office, Augusta was disposed of in 1960 and sold to the breakers.

Augusta received but three battle stars for her World War II service. Her name has been recycled for an Independence-variant littoral combat ship (LCS-34) that was commissioned in 2023.

Battleship Nukes

While a number of battleships met their end at the hand of atomics at Bikini Atoll, likely the only dreadnoughts to carry nuclear weapons for tactical use were the Iowa class.

Those fast battleships “may have” toted such devices in two forms.

Between 1956 and 1962, the Navy had a limited stockpile of about 50 MK-23/W23 “Katie” nuclear shells for the Iowas‘ 16-inch guns, each with a yield of some 15-20 kilotons, with most ships of the class equipped to carry as many as 10 of these mushroom makers. Of note, Hiroshima’s Little Boy was a 15kt bomb.

Per NavWeaps:

USS Iowa, USS New Jersey, and USS Wisconsin had an alteration made to Turret II magazine to incorporate a secure storage area for these projectiles (the Nuclear projectile). USS Missouri was not so altered as she had been placed in reserve in 1955. This secure storage area could contain ten nuclear shells plus nine Mark 24 practice shells.

These nuclear projectiles were all withdrawn from service by October 1962 with none ever having been fired from a gun. One projectile was expended as part of Operation Plowshare (the peaceful use of nuclear explosive devices) and the rest were deactivated. USS Wisconsin did fire one of the practice shells during a test in 1957. It is not clear whether or not any of the battleships ever actually carried a nuclear device onboard, as the US Navy routinely refuses to confirm or deny which ships carry nuclear weapons.

At least one inert Mark 23 shell body still exists at the National Atomic Museum in Albuquerque, New Mexico.

Enter TLAM-N

Then in the 1980s came TLAM-Ns, the so-called nuclear Tomahawk cruise missile with its W80 150 kiloton warhead. First fielded in selected fleet units, only about 300 made were produced and the Obama administration dismantled them in 2010.

Below is a great video done by the curator of the USS New Jersey (BB-62) Museum, where he shows off the (possibly) TLAM-N related areas of the ship, including the panels, Marine guard post, and ABLs.
