E-11 BACN/HAG

The E-11 BACN/HAG program is a specialized Air Force initiative focused on the procurement and integration of the Battlefield Airborne Communications Node (BACN) capability. BACN is designed to provide Combatant Commanders with a flexible, long-endurance, and responsive airborne communications platform. The primary objective of this program is to enable robust voice and data communications bridging, translation, and relay functions, particularly for beyond-line-of-sight (BLOS) operations. This capability is critical for ensuring seamless connectivity between disparate tactical data link networks and supporting warfighters in complex operational environments.

The BACN system is hosted on the E-11 aircraft, which serves as the airborne platform for this advanced communications payload. The program's goals include the procurement of both the host aircraft and the BACN payload, as well as the integration of emerging communications capabilities. This involves acquiring Supplemental Type Certificates (STC) and necessary provisioning supplies to ensure the aircraft and payload meet operational and safety standards. The program also encompasses initial maintenance, sustainment support, and associated system costs to guarantee the long-term viability and readiness of the BACN-equipped fleet.

For Fiscal Year 2026, the budget line item E011A1 for E-11 BACN/HAG does not request new procurement funding. The justification notes that funding for this capability is included in Program Element (PE) 0207238F, which covers BACN-related activities and investments. The FY 2024 budget included funding for the procurement of one E-11 BACN unit, reflecting an investment in maintaining and expanding the Air Force's airborne communications infrastructure. No additional procurement quantities or funding are projected for FY 2025 and FY 2026 under this specific line item.

The program's objectives are closely aligned with the Air Force's broader communications and interoperability goals. By providing a dedicated airborne gateway for tactical data links and voice communications, BACN enhances command and control capabilities across joint and coalition forces. This is particularly important in environments where ground-based communications infrastructure is limited or disrupted, allowing for continuous situational awareness and coordination during operations.

Procurement activities under the E-11 BACN/HAG line item include not only the acquisition of aircraft and payloads but also the integration of new technologies as they become available. The program supports the evaluation and incorporation of emerging capabilities to keep pace with evolving operational requirements and technological advancements. Additionally, initial spares, maintenance, and sustainment support are factored into the program to ensure that newly procured systems are fully operational and supported throughout their lifecycle.
