The improvised nuclear bomber that could never land on a carrier

In short: In 1948, the US Navy faced a crisis of relevance. To maintain its standing, it needed a nuclear strike capability. The solution was a desperate improvisation: modifying the land-based P2V Neptune with rocket boosters to launch from carriers, even though the aircraft was never designed to land on them.

The Lockheed P-2 Neptune was designed as a land-based maritime patrol and antisubmarine warfare aircraft. However, the geopolitical pressures of the early Cold War forced a radical shift in its mission. Following the 'Revolt of the Admirals,' the US Navy sought to secure a nuclear strike capability to ensure its continued relevance. Because the massive Fat Man nuclear munitions of the era required large aircraft, the Navy turned to the Neptune, modifying it for carrier launches using jet-assisted takeoff (JATO) rocket boosters.

This improvised role came with a lethal caveat: the Neptune was not designed for carrier landings. Pilots tasked with nuclear strikes had to either land at a friendly shore base or ditch the aircraft in the sea near a US Navy vessel. While the Navy eventually transitioned this role to the North American AJ Savage in October 1952—the first nuclear strike aircraft capable of both carrier launch and recovery—the Neptune's versatility allowed it to serve in many other capacities.

Beyond nuclear strikes, the Neptune became a vital tool for covert operations. Under the CIA's 'Project Cherry,' Lockheed's Skunk Works converted several aircraft into RB-69A variants for electronic intelligence (ELINT) missions. These were used by the Republic of China Air Force's 'Black Bat Squadron' to penetrate mainland China. The mission was high-stakes and high-loss; all five of the original CIA-provided aircraft were lost with all hands on board, either crashing in South Korea or being shot down over China.
