| | REGULUS II CRUISE MISSILE |
 | | However, the Regulus II cruise missile project was cancelled on December 18, 1958, as the United States Navy decided to develop the submarine-launched Polaris ballistic missile, instead, and the Regulus I cruise missile remained in service until 1964, on the USS Halibut, with 514 of them being built. |
 | | The 11-ton Regulus II cruise missile, which was powered by a General Electric J79 jet engine, had a wingspan of 20 feet and 1 inch (6.12 meters), a length of 57 feet and 6 inches (17.5 meters), a range of 1,380 miles (2,220 km), and 54 of them were built. |
 | | The only submarine-based firing of the Regulus II cruise missile, from the USS Grayback, occurred in September 1958 and some of these were still in use by the USN after 1958, as reuseable supersonic target drones, equiped with landing gear. |
