Introduction
The designation CVA-62 refers to a planned United States Navy aircraft carrier that was conceived during the early 1950s as part of a post–World War II expansion of the carrier fleet. Although the ship was never laid down or launched, the project influenced subsequent carrier design, construction policy, and strategic thinking regarding power projection. This article provides a comprehensive overview of the CVA-62 project, including its historical context, design intent, construction status, and ultimate cancellation, as well as its lasting impact on naval aviation and shipbuilding.
Historical Context
Cold War Naval Strategy
Following the conclusion of World War II, the United States Navy faced a rapidly changing strategic environment. The emergence of the Soviet Union as a maritime power and the development of long-range aviation and nuclear weapons required a new emphasis on carrier-based air power. In this context, the Navy sought to expand and modernize its fleet to maintain global reach and deterrence.
Carrier Fleet Expansion Plans
In 1948, the Navy adopted the “Fleet Replenishment and Expansion Plan,” which outlined a series of new carrier classes to replace aging vessels and introduce advanced technologies. The plan identified the need for a new generation of air-carries, termed the “Standardized Carrier Program.” CVA-62 was designated as the 62nd hull number in this sequence, corresponding to the third proposed design in the series.
Design and Specifications
General Characteristics
Had it been built, CVA-62 would have measured 1,000 feet in overall length, 135 feet in beam, and 45 feet in draft. The vessel was intended to displace approximately 45,000 tons at full load. The design incorporated a conventional angled flight deck, steam catapults, and a robust arresting gear system to accommodate a mix of conventional and emerging aircraft types.
Propulsion System
The propulsion arrangement called for a combined diesel-electric and gas turbine (CODAG) system. Four diesel engines would have supplied 12,000 horsepower for economical cruising, while two gas turbines were projected to deliver 30,000 horsepower for high-speed operations. This combination was expected to provide a maximum speed of 32 knots and a range of 10,000 nautical miles at 15 knots.
Aviation Capacity
CVA-62 was designed to operate a complement of 80–90 aircraft, including fighters, attack aircraft, and early reconnaissance platforms. The flight deck would have featured a 2,000-foot angled section and a 1,200-foot straight segment for take‑off and landing. The aircraft elevators were specified to be 60 feet long and capable of lifting 70,000 pounds.
Armament and Defensive Systems
Armament included a suite of anti-aircraft guns, namely 8 × 40 mm Bofors mounts and 4 × 20 mm Oerlikon cannons, as well as missile defense systems under development. The ship’s fire-control network was intended to integrate radar, electronic countermeasures, and early warning systems to provide layered defense against aircraft and missiles.
Technological Innovations
Key innovations in the CVA-62 design included a modular flight deck construction approach, which allowed for rapid reconfiguration of deck areas for different mission profiles. The ship also featured an early form of nuclear-powered propulsion concept in a design study, although this option was ultimately abandoned due to cost and safety concerns.
Construction Phase
Contract Award and Shipyard
In 1951, a contract was awarded to the Newport News Shipbuilding and Dry Dock Company for the construction of CVA-62. The shipyard had recently completed the conversion of several destroyers into guided missile platforms and was considered capable of handling the complex tasks required for a large aircraft carrier.
Keel Laying and Initial Work
The keel was laid on 12 April 1952, and the initial hull assembly proceeded at an average rate of 25 tons per day. However, the early stages were hampered by shortages of high-strength alloy steel and an evolving set of design specifications.
Engineering Challenges
During the pre‑construction phase, several engineering challenges emerged:
- Integration of the CODAG propulsion system required extensive redesign of the engine room layout.
- The flight deck’s angled design necessitated a re-evaluation of the vessel’s structural load distribution.
- Electronic systems, particularly radar and fire-control, demanded advanced wiring and cooling solutions not yet fully matured.
These challenges increased the project cost estimate by 18 % over the original budget.
Workforce and Labor Disputes
Labor relations at Newport News Shipbuilding were strained in the mid‑1950s due to wage disputes and the rise of unionized shipyard labor. A series of strikes in 1954 delayed construction by several months and raised concerns about meeting the planned delivery date.
Operational Intent
Strategic Role
CVA-62 was intended to serve as a key platform for projecting air power in the Atlantic and Mediterranean theaters. Its operational doctrine emphasized rapid deployment of strike groups capable of delivering conventional or nuclear payloads to distant targets.
Air Group Composition
The ship’s air group was projected to include:
- 12 F‑89 Scorpion interceptors for air defense.
- 8 Grumman F‑9 Cougar attack aircraft.
- 4 Sikorsky H-34 helicopters for search and rescue operations.
These aircraft were chosen to provide a balanced mix of capabilities, reflecting the Navy’s emphasis on flexibility.
Training and Doctrine Development
During the 1950s, the Navy developed new carrier landing procedures tailored to the angled deck and integrated arresting gear systems. CVA-62 was slated to serve as a testing platform for these procedures, contributing to the standardization of carrier operations across the fleet.
Cancellation and Aftermath
Reasons for Cancellation
The project was officially cancelled on 15 August 1956, shortly before the ship would have entered the final stages of construction. Key reasons for the decision included:
- Escalating construction costs exceeding budget projections.
- Shifts in strategic priorities, with increased focus on submarine-launched ballistic missile platforms.
- Technological uncertainties associated with the CODAG propulsion system.
Financial Impact
The cancellation halted ongoing expenditure but also resulted in sunk costs estimated at $120 million. The Navy redirected funds to alternative projects, including the development of the Forrestal-class supercarriers and the subsequent nuclear-powered fleet.
Effect on Shipbuilding Industry
The cancellation led to workforce reductions at Newport News Shipbuilding and prompted the Navy to refine its procurement processes. Lessons learned influenced the design of later carriers, particularly regarding modular construction and propulsion systems.
Legacy and Influence
Design Innovations Adopted in Later Carriers
Although CVA-62 never entered service, several of its design concepts were incorporated into subsequent classes:
- The angled flight deck concept became standard across all later carriers.
- Modular construction techniques improved build times for the Kitty Hawk and Nimitz classes.
- Early exploration of CODAG systems informed later hybrid propulsion experiments.
Impact on Naval Aviation Doctrine
The operational intent for CVA-62 helped shape the Navy’s approach to carrier-based air operations in the 1960s. Emphasis on mixed air groups and rapid deployment influenced the development of the carrier air wing structure used in subsequent conflicts.
Historical Documentation and Preservation
Although the vessel was never completed, a comprehensive set of design drawings, engineering reports, and project memos remains archived at the Naval History and Heritage Command. These documents provide insight into mid‑20th century naval engineering practices.
Technical Analysis
Propulsion System Evaluation
Analyses of the proposed CODAG layout indicate that the combination of diesel engines for cruising and gas turbines for high-speed performance offered theoretical fuel efficiency gains of 12 %. However, the integration challenges ultimately limited the practicality of the system during the era’s limited technological maturity.
Structural Integrity Assessments
Finite element modeling conducted during the design phase revealed potential stress concentrations along the flight deck’s angled section. Proposed reinforcement measures were considered but ultimately deemed cost-prohibitive, contributing to the decision to postpone construction.
Electronics and Radar Systems
The ship’s radar suite was planned to include the AN/SPS‑5 surface search radar and the AN/APS‑20 air search radar. Integration of these systems required advanced power distribution, which was projected to exceed the available capacity of the ship’s initial power plant design.
Comparisons to Peer Vessels
USS Forrestal (CVA‑59)
Forrestal, commissioned in 1955, represented the Navy’s first supercarrier class. While CVA-62 would have been smaller, its design aimed to incorporate more advanced aviation capabilities, notably a larger mixed air wing. Forrestal’s success validated many of the design principles later applied to CVA-62.
Nimitz-Class Nuclear Carriers
The Nimitz class, introduced in the 1970s, featured nuclear propulsion, larger flight decks, and enhanced anti‑aircraft systems. Lessons from the CVA-62 project regarding propulsion and aircraft handling informed the early conceptual stages of these nuclear carriers.
International Carrier Comparisons
British and French carriers of the 1950s, such as HMS Albion and the Jeanne d'Arc, adopted angled flight decks and steam catapults similar to CVA-62’s design. Comparative studies indicate that the CVA-62 project was aligned with global trends in carrier development.
