USS Illinois: The battleship that was about to become an aircraft carrier

The USS Illinois, one of the iconic battleships of World War II, was at the center of a historic crossroads. In a period of strategic changes in shipbuilding, proposals arose to transform this battleship into an aircraft carrier, which represented a radical change in the naval strategy of the time.

Advances in shipbuilding during World War II

The 1930s saw the rise of three new classes of fast battleships: the North Carolina, South Dakota, and the iconic Iowa class. These battleships were noted for their sheer size and impressive armor, becoming the most powerful ships in the world.

The new classes of fast battleships

The North Carolina, South Dakota, and Iowa classes represented a significant advance in shipbuilding. With a displacement of 45,000 tons, these battleships featured unique features and impressive firepower.

The Iowa-class battleships were equipped with nine 16-inch main guns in three triple turrets and twenty 127 mm secondary guns. These vessels demonstrated their firepower and became a symbol of America’s naval power.

The USS Illinois: A Historic Crossroads

In the midst of this era of strategic change, the USS Illinois found itself at a historic crossroads. As the United States Navy focused more and more on building aircraft carriers, some visionaries contemplated the possibility of taking advantage of the construction of the USS Illinois and transforming it into one of these ships.

With the gathering of the dark clouds of war in the 1930s, the US Navy prioritized constructing aircraft carriers. These airships were considered essential for battlefield power projection and air support.

As construction of the USS Illinois progressed in Illinois in 1945, events in the Coral Sea and Midway raised the possibility of converting the battleship into an aircraft carrier. Changes to her design were proposed, such as the installation of flight decks and armament similar to that of the Essex-class aircraft carriers.

Innovations in the design of the USS Illinois

USS Illinois featured key design innovations that set it apart from its predecessors and sought to improve strength and reduce weight.

One of the most notable innovations of the USS Illinois was its fully welded construction, which saved weight and increased the strength of the ship. This construction technique represented a significant advance in the shipbuilding industry of the time.

During the construction of the USS Illinois, the possibility of redesigning the hull with a Montana-type protection system was contemplated to deal with the threats of enemy torpedoes. However, this proposal was eventually scrapped.

Aircraft carrier conversion plans

As proposals to convert the USS Illinois to an aircraft carrier emerged, the requirements and limitations of such a conversion were evaluated.

It was proposed to equip the USS Illinois with flight decks and armament similar to that of the Essex-class aircraft carriers. However, these plans were quickly scrapped due to limitations in aircraft-carrying capacity and the high costs associated with the conversion.

Given the constraints and costs associated with the conversion to an aircraft carrier, the decision was made to continue construction of the USS Illinois as a battleship, albeit with low priority.

The end of the USS Illinois

Unfortunately, work on the USS Illinois was suspended in August 1945, just days after the atomic bomb turned the tide of the war in the Pacific.

The battleship was removed from the Naval Register of Ships, and various proposals for completion as a guided missile battleship were considered but ultimately abandoned due to cost and rapidly evolving missile technology.

The legacy of the USS Illinois

Although the USS Illinois failed to achieve its original destiny as a battleship, it remains a testament to the strategic evolution and challenges faced by shipbuilders during World War II. The unfinished hull of the USS Illinois stood as a reminder of a missed opportunity in American naval history until it was finally scrapped in 1958.

Conclusion

The USS Illinois represents a fascinating chapter in America’s naval history. Although she was about to turn her course into the skies as an aircraft carrier, the limitations and historical events of the time led to the completion of her as a battleship. Her innovative design and her conversion proposals show the constant evolution of naval strategies and technologies during World War II.
