The Air Force is preparing to shut down a specialized airborne communications fleet
The U.S. Air Force is seeking to retire its E-11 Battlefield Airborne Communication Node aircraft in fiscal 2028, according to written testimony submitted to the House Appropriations defense subcommittee. The move would close out a program that has operated since 2005 and has served as an airborne data-relay capability for forces operating across large, difficult theaters.
An Air Force spokesperson told Breaking Defense that the current fleet consists of seven E-11 aircraft. The same spokesperson said the service plans to replace the capability with the emerging Department of the Air Force Battle Network, signaling a shift away from a dedicated communications relay aircraft and toward a broader, more distributed architecture.
What BACN has done
The BACN system, integrated on a modified Bombardier Global business jet by Northrop Grumman, has often been described as providing "Wi-Fi in the sky." In practical terms, the aircraft functions as a communications bridge, helping connect platforms and users that might otherwise struggle to exchange data directly. That role has been especially valuable in large operational areas and in situations where line-of-sight communications are limited.
Its importance has come from translation and relay as much as from raw bandwidth. A platform like the E-11 can sit above the battlespace and help stitch together different users, sensors, and networks. For years, that made it a recognizable example of how the Pentagon tried to solve command-and-control problems with purpose-built airborne nodes.
Why the service is changing course
The Air Force's fiscal 2027 budget documents zero out funding for the E-11 program. Breaking Defense reported that the service has spent a total of $296 million on the program since its inception. Budget decisions at that level usually reflect more than a desire to trim a single fleet. They also show where leaders believe future operational advantage will come from.
In this case, the answer appears to be an enterprise network rather than a stand-alone aircraft type. By pointing to the Department of the Air Force Battle Network as the replacement path, the service is aligning the retirement with its wider push to create more connected, resilient command-and-control systems across aircraft, satellites, and other nodes.
The testimony also indicates that the service sees a near-term gap that has to be managed rather than ignored. For now, officials say a Hybrid SATCOM Terminal program will serve as a bridge capability. That suggests the Air Force is not assuming the new architecture will instantly reproduce every function the E-11 provided.
A transition with operational implications
The Air Force budget documents and testimony show plans to integrate satellite communications terminals on other aircraft, including the KC-135 Stratotanker and the B-1 Lancer. That approach spreads connectivity tools across a wider set of platforms instead of concentrating the mission in a small dedicated fleet.
There are advantages to that strategy. A distributed network may be harder to disrupt and easier to scale across force packages. It may also reduce dependence on a tiny inventory of unique aircraft. But the transition carries risk because a niche platform often survives precisely because it solves a real operational problem that general-purpose systems do not fully match.
The E-11's planned modifications underscore that point. Future upgrades had included software enabling use of the GPS system's jam-resistant M-code, a capability considered important for operations in highly contested electromagnetic environments. If the fleet is retired before that evolution occurs, the burden shifts to other platforms and network programs to deliver equivalent resilience.
What this retirement says about the next phase of air combat networking
The proposed divestment is less about declaring airborne communications relay unnecessary than about redefining how the mission should be performed. The Air Force appears to be betting that future connectivity will come from a mesh of systems rather than from a single recognizable platform circling overhead.
That is a familiar pattern across military modernization efforts. Specialized fleets that once solved urgent operational challenges are increasingly being judged against larger concepts built around integration, software, and multi-domain networking. The E-11 now seems to be entering that category.
Whether that proves efficient or premature will depend on how quickly the replacement architecture matures. For the moment, the clearest fact is that one of the Air Force's most distinctive communications aircraft is on a path toward retirement, and that the service wants its next answer to the connectivity problem to be broader, more distributed, and more tightly tied to the future battle network it is still building.
