USS Ranger (CV-4)

The USS Ranger (CV-4) was the first US Navy aircraft carrier to be entirely conceived as such from the outset, from the keel up. However, it was designed to comply with the limitations of the Washington Naval Treaty of 1922. Being the only one of her class, she was laid down on September 26, 1931. She was built by Newport News Shipbuilding & Dry Dock, at the shipyards in Virginia. She was launched on February 25, 1933, being commissioned on June 4, 1934.

Technical Characteristics

When she was commissioned in 1934, the USS Ranger introduced several features that would become common in future US Navy prewar carrier designs. Although her original design did not have an island, it would soon be added to the plan right after construction had begun. She was also fitted with an open hangar, a gallery deck around the flight deck, and provision for cross-deck catapults mounted on the hangar deck. She had six hinged funnels, three on each side of the ship aft portion. However her narrow hull was provided with no underwater protection.

The Ranger's design was optimized to support the maximum number of aircraft. Her hangar deck was actually larger than that of the Lexington class. Two elevators were fitted close together amidships in an unusual arrangement, with the purpose of clearing space for the hangar deck catapults, although they were never really mounted. Thus, her aircraft capacity was 76 combat planes, including 36 fighters and 36 dive-bombers. At the time of her design, dive-bombers were seen as the most destructive anti-ship weapons. Despite being an advanced aircraft carrier when she was launched, the USS Ranger had several shortcomings. Her sea-keeping was relatively poor as heavy seas restricted flying to a significant degree. However, she would be fitted with the RCA CXAM-1 radar in November 1942.

Service

Since she was not fast enough for major fleet operations in the Pacific Theater of World War II, the USS Ranger (CV-4) was assigned for support operations in the Mediterranean Theater. In late 1942, she took part in Operation Torch, which was the Allied landings on the coasts of North Africa. In 1943, after taking part in an air raid against German bases in Norway, she would be sent home and refitted and, from then on, she would become a training carrier off the coast of Rhode Island for the new US Navy's pilots. After the war, in 1947, she was sold for scrap.
