US Navy selects Lockheed-based Phoenix II as next-generation TACAMO replacement

Maintaining the current E-6B fleet has become increasingly difficult due to its age. To address these challenges, the Navy chose a modernized version of an established design—the C-130J—for improved reliability and easier maintenance because parts remain widely available thanks to ongoing production of C-130 variants.

Northrop Grumman secured a contract in 2024 to develop and deliver the E-130J Phoenix II, which is expected to enter service in 2028. The new aircraft will include advanced communications equipment aimed at ensuring secure command and control functions even under extreme conditions. Enhanced survivability features such as updated defensive systems and electronic warfare capabilities are also planned.

The Phoenix II’s versatility includes being able to operate from shorter or less developed runways than its predecessor—a capability not present in the larger Boeing-based Mercury aircraft.

Transitioning operations from the E-6B to the E-130J is scheduled for completion by early in the next decade. While offering technological advancements, Northrop Grumman will streamline some functionalities; notably, "the E-130J will not serve as an airborne command post." Instead of handling all strategic communications duties—including those with ICBM silos or submarines—the military plans to shift some responsibilities to future platforms like "the Air Force's upcoming E-4C Survivable Airborne Operations Center," which is being developed using a Boeing 747-8 base model by Sierra Nevada Corporation for anticipated entry into service around 2032.

With fewer onboard roles required for this new generation of TACAMO aircraft—and by leveraging commonality with existing fleets—the Navy expects operational cost savings while increasing flexibility through short-field performance.
