USS Oregon City (CA-122) was the lead ship of four heavy cruisers built for the US Navy. The class was ordered in 1944 as a revised design of the Baltimore class. The Oregon City class featured a similar "compact pyramidal" superstructure with a single trunked funnel, intended to provide better firing angles for the guns on board, similar to the design of the Fargo-class light cruiser in relation to the Cleveland class. However, due to significant budget cuts at the end of the war, along with the advent of anti-ship missiles, only four ships out of the ten originally ordered were completed, and they were effectively decommissioned at the end of the Korean War.

As for Oregon City, she was laid down on 8 April 1944 at the Bethlehem Steel shipyard in Pennsylvania, launched on 9 June 1945, and commissioned on 16 February 1946. Due to budget cuts, along with the later introduction of the Des Moines class, Oregon City was considered obsolete and was decommissioned just about a year later, on 15 December 1947. She spent over 26 years in the Mothball Fleet before finally being scrapped on 17 August 1973.

USS Oregon City was introduced in Update "Spearhead". Essentially an optimised version of USS Baltimore, Oregon City features slightly fewer but still numerous AA guns, though the change in layout allows more guns to be aimed at enemy aircraft and effectively creates a "no-fly zone" around it. Aside from this, Oregon City is largely similar to Baltimore in other aspects. Her slow-firing 8-inch guns have access to super-heavy APCBC shells, which allow her to damage most ships she faces, in addition to versatile 127 mm secondary guns. However, despite the large crew count for a cruiser and the optimised layout, Oregon City will often have to face battleships, which often possess enough firepower to negate its protection, even at range.
