This is a suggestion for USS Marblehead (CL-12), an Omaha Class Light Cruiser, as of her experimental 1932 refit. The 1932 refit represents what was to have been a standard refit for most of the class to address various issues with the original top-heavy design. However, owing to the cost of the modifications and the ongoing economic issues, Marblehead would be the only ship to receive this fit. The 1932 fit would be a worthy addition to the US Bluewater Rank III lineup. It would give players a unique Omaha class Light Cruiser with a better broadside weight than the current standard 1930 and 1941 refits in the game. Gameplay-wise, the ship would function similarly to the other Omaha-class Cruiser in the game, apart from having a very slightly stronger broadside and less AA.

Background

Spoiler

The Omaha class was a group of 10 light cruisers ordered in 1918 by the United States Navy as high-speed scout cruisers. Their role would be to scout out enemy forces while being able to outrun most enemy destroyers and some cruisers. As part of this design requirement, the class would feature a top speed of 35 knots and would be of very light construction. Several designs were considered for this Battle Scout program, including ships with up to 16" guns, as there were doubts about whether a small cruiser could effectively breach an opponent’s cruiser line. The US Navy would later build upon these ideas and form the US Navy’s first and only Battlecruiser class, the Lexington class. However, in the end, the Navy rejected the concept of so-called “Battle Scouts” armed with 14"to 16" guns, and instead, development switched to the original goal of a Scout Cruiser armed with 6" guns. The finalized design would be designated as the Omaha-class after the lead ship. However, they would never serve in their intended Scout Cruiser role. Instead, they would be re-designated as Light Cruisers following the signing of the Washington Naval Treaty and act in the fleet screening role for most of their active service lives.

History

The general history of the Omaha class begins with the single constant aspect of naval design and development: delays. These delays came about because of the First World War. They were also caused by the US Navy Bureau of Engineering and the Bureau of Ordnance recommending various modifications and other changes to the design of the Omaha-class. With these delays, the construction of the later Omaha class cruisers, specifically CL-8 to CL-13, was delayed so the shipyards and designers could undertake the suggested modifications. The resulting modifications created numerous new problems for the Omaha-class, and despite the various refits and conversion proposals, they would never be resolved. These modifications and further redesigns would turn an already tight design into a badly overloaded design with even more serious flaws. For example, the ships did not have adequate space aboard for their crew, nor were they able to operate in tropical areas owing to their bare steel decks, which tended to heat up quite quickly and caused injuries among the crew. Despite these delays and other general issues with the class, the ships designated CL-7 through CL-13 were eventually laid down, albeit slightly behind schedule.

USS Marblehead (CL-12) was ordered by the US Navy on 1 July 1918, with the contract for the construction awarded to William Cramp and Sons shipyard in Philadelphia on 24 January 1919. The ship was assigned yard number 502 and would be laid down a year later, on 4 August 1920. Construction would last three years, and the vessel would launch on 9 October 1923. Marblehead would undergo nearly a year of fitting out and sea trials before being commissioned into the US Navy as USS Marblehead (CL-12) on 8 September 1924.

Following her commissioning, Marblehead was sent out on a massive shakedown cruise, which saw her take on a circumnavigation voyage. As part of this voyage, the ship visited the English Channel and the Mediterranean while visiting various countries. On the ship’s return voyage in 1925, she would also visit Australia and the Galapagos Islands.

Upon her return to the United States, she received orders to sail on another extended journey. In early 1927, Marblehead was on hand to assist in negotiations between the various factions of the Nicaraguan Civil War, which led to the Peace of Tipitapa. The ship would later be sent to the Pacific as a show of force to protect the delegates and foreign nationals living in the international settlement, which was then under siege during the Chinese Civil War. Aside from her assignment in Shanghai, she would also spend two months patrolling the Yangtze River before being sent home to the United States. However, she would stop in Nicaragua to assist in preparing for the Nicaraguan elections as specified under the Peace of Tipitapa.

In late 1932, the ship underwent a refit as part of an experimental proposal to correct some of the prevailing issues with the class, namely their overloaded design. As part of this refit, her aft upper casemate 6"/53 guns were removed and replaced with a single 6"/53 mounted centerline. Due to the expense of this refit, however, all further refits to the Omaha class were shelved. Marblehead would be the sole ship of the class to receive this experimental refit.

During the 1930s, Marblehead spent most of the decade split between the Atlantic Fleet and the Pacific Fleet, with her Atlantic service lasting from August 1928 until January 1933 and her Pacific service lasting from February 1933 until January 1938. However, in January of 1938, Marblehead’s assignment to the Asiatic fleet was extended owing to the tensions between the US and the Empire of Japan. Seven months later, she was permanently assigned to the Asiatic Fleet and homeported at Cavite in the Philippines. She would spend the next three years cruising the Sea of Japan and the South and East China Seas as tensions increased. In 1940, she would once again be refitted with her single upper aft casemate mount removed and replaced by an additional 3"/50 gun and several .50 (12.7mm) Machine Guns added.

WWII

On 25 November 1941, Marblehead and the other ships of Task Force Five (TF5) received an order from the commander of the US Asiatic Fleet to depart Manila Bay for seemingly routine exercises. However, in Marblehead’s War Diary, her commander noted that Asiatic Fleet Command had sensed that relations between the US and Japan had reached a critical state. Aside from this, there were also indications that the Japanese were deploying their warships. Marblehead and TF5 would thus sail to Tarkan, Borneo. They would anchor there on 29 November to await further instructions, which would come on 8 December 1941 as a note announcing the commencement of hostilities between the United States and the Empire of Japan.

As the ship was undamaged in the opening stages of the War in the Pacific, she and TF5 received orders to screen vital shipping that was moving south from the Philippines as part of a joint Australian, British, Dutch, and American squadron known as ABDACOM. Initially, Marblehead and the rest of the squadron could easily maintain their patrols, and as seen on 24 January 1942, they could disrupt Japanese operations. However, six days later, when attempting to recreate their earlier success, the squadron, after trying to chase and destroy two separate convoys that successfully evaded them, came under concentrated air attack from land—and sea-based bombers in what would become known as the Battle of Makassar Strait.

At 0949 on 1 February 1942, 37 Japanese Aircraft broke through the clouds and descended on Marblehead’s formation. As the ships scattered, a formation of seven Japanese twin-engine bombers in a “V-Formation” began a power glide toward Marblehead. However, Marblehead AA Gunners were able to put up an impressive defense that forced the Japanese bombers to abandon their attack run and turn around to try and get a better angle. Over the next several minutes, Marblehead was able to evade attacks and take down several Japanese Aircraft while taking no hits herself. However, at 1026, after numerous failed attacks, a flight of bombers lined up on Marblehead. Despite the crew’s best efforts, all seven were able to complete their drop on Marblehead to devastating effect. Of the at least seven bombs (according to Japanese sources 14 were dropped), two hit and four were near misses.

The first hit penetrated Frame 47 after hitting the ship’s motor launch, likely setting off the fuse delay. The bomb exploded on the main deck, obliterating the ship’s sickbay, rupturing all steam, water, and electrical lines, and destroying the ship’s forward fuel tank, causing a massive fire. The second bomb struck near the aft of the after 6" mount and penetrated the deck, exploding in the auxiliary steering room. This hit also severed all rudder control, leaving the ship locked in a hard-to-port turn and destroying several fuel tanks, which caused a massive fire aft. The near misses also caused devastating damage by opening up seams, shearing off rivets, and forming a three-by-nine-foot hole in the ship’s side, letting in hundreds of tons of water. Several more attacks followed, but eventually, Japanese aircraft began ignoring the ship as it seemed ever likely that she would sink. However, due to excellent damage control, the ship was able to return to port, where temporary repairs were made. In a twist of fate, however, Marblehead was further damaged in a collision with a Dutch tugboat that bent her bow 8 degrees to starboard. Marblehead would finally leave the port of Tjilatjap on 13 February for the Brooklyn Navy Yard for emergency repairs.

What followed was a long and arduous journey of over 30,000 kilometers to return to the Brooklyn Navy Yard for repairs. During this voyage, Marblehead operated with several compartments open to the seas and without an operational rudder. The ship spent most of the journey steering with her engines. Marblehead was eventually able to sail to Simonstown, South Africa, where she would arrive on 24 March 1942 for emergency repairs. The ship would depart on 15 April for the Brooklyn Navy Yard and arrived on 4 May 1942 for further repairs. While undergoing repairs, the ship also underwent a significant refit to strengthen its Anti-Air capabilities further.

Following a lengthy repair period from May 1942 and lasting until October of the same year, Marblehead was attached to the South Atlantic Force stationed out of Recife and Bahia, Brazil, until February 1944. In February 1944, she would undergo her final refit, further increasing her anti-air capabilities. She would then be ordered to sail to the Mediterranean, more specifically Palermo, to join the fleet staging for Operation Dragoon. During Operation Dragoon, the cruiser engaged shore defenses and provided coastal fire support for the troops landing in Southern France. Following this, she would withdraw to Corsica.

Marblehead spent the rest of the war patrolling the Mediterranean before finally being ordered home for a summer cruise for the US Naval Academy. Ultimately, however, she was decommissioned on 1 November 1945 and laid up until being sold for scrap on 27 February 1946, ending the career of USS Marblehead (CL-12).
