HitchAI read

U.S. Air Force funding falls 19% to a $26.4M request in FY2027, sustained across the five-year plan. In the FY2027 defense authorization, the House cut 10.0% (to $23.8M); the Senate funded it in full; House appropriators funded it in full. NSA leads the industry work, though an unusually large share flows to government labs and warfare centers.

Common Data Link Executive Agent (CDL EA) provides the DoW standard for interoperable, multi-service, multi-agency, Intelligence, Surveillance, and Reconnaissance (ISR) datalinks for 15,000 DoW manned/unmanned airborne and ground terminals. The project advances CDL through partnership with each of the Services, NSA, JITC, FFRDCs, and Industry. As the DoW CDL EA, the Air Force applies CDL RDT&E Military Intelligence Program (MIP) funds, using cross-Service teams, ensuring compliance with DoW waveform mandates. The CDL EA develops, modifies, distributes, and maintains specifications for the CDL waveform family; ensuring design configuration control, commonality, and interoperability among ISR platforms. The CDL EA also funds and supports cross-Service teams that manage development, maturation, and migration of CDL technologies. CDL EA enables compliance with OSW mandates to effectively utilize spectrum, use approved cryptographic equipment, and provide direct support to current operations. CDL is a vital link in DoW's existing and emerging communication architectures, providing flexibility to accommodate Command and Control (C2) data and myriad types of Signals Intelligence (SIGINT), Geospatial Intelligence (GEOINT), and Full-Motion Video (FMV) data. The CDL specifications enable interoperable operations of current and future ISR assets worldwide by providing sensor data directly via point-to-point and networked air-to-air or compatible satellite broadcast links to ground sites, surface ships, airborne platforms, and dismounted users, supporting Combined Joint All-Domain Command and Control (CJADC2) warfare. The CDL EA effort advances top-line CDL capabilities while maintaining compatibility with fielded U.S. and Allied terminals CDL EA's research and development activities support a broad array of tactical (including tactical data links (TDL) and high capacity backbone (HCB)), operational, and strategic ISR users. High priority investment activities support and include: achieving higher data rates, open architecture development, multi-access and multi-node network management, cryptographic modernization, advancements needed to operate in contested environments, terminal design enhancements, and operations in other spectral bands for spectrum efficiency.

FY2026 to FY2027 change The reduced budgetary allocations for Accomplishments/Planned Programs come from a department of War program funding cut of 20% across the FYDP. The Common Data Link (CDL) program focused on core competencies of waveform specification maintenance and updates, as well as cryptographic core modernization and SERD 2.0 compliance.

FY2026 plans — current year - Continue to research and evaluate developing technologies to minimize the National Security Agency (NSA) required certification requirements for terminals while standardizing Communications Security (COMSEC) implementation. - Continue incorporating data Transmission Security (TRANSEC) support, data handling capabilities, and new cryptographic algorithms into all cryptographic core form factors (i.e., Nano, Mini and Mega). - Continue to upgrade Nano and Mini crypto cores with customer requested Engineering Change Proposals (ECP) and complete Security Validation Testing (SVT) and subsequent National Security Agency (NSA) Cyber Security Certification. - Continue to ensure CDL family of…

Mission & acquisition strategy

Common Data Link Executive Agent (CDL EA) provides the DoW standard for interoperable, multi-service, multi-agency, Intelligence, Surveillance, and Reconnaissance (ISR) datalinks for 15,000 DoW manned/unmanned airborne and ground terminals. The project advances CDL through partnership with each of the Services, NSA, JITC, FFRDCs, and Industry. As the DoW CDL EA, the Air Force applies CDL RDT&E Military Intelligence Program (MIP) funds, using cross-Service teams, ensuring compliance with DoW waveform mandates.

The Air Force serves as the DoD Common Data Link Executive Agent, with support from each Service's designated CDL lead and AFLCMC/HNA (Airborne Network Division). The CDL EA develops interoperable ISR data links mandated for use by DoW CIO policy. Once CDL technology development matures and a specification is published, services are responsible for CDL compliant platform and terminal procurement; National Security Agency (NSA) and Joint Interoperability Test Command (JITC) ensure compliance certifications; integration; and installation. Acquisition strategy varies by Service and contract. Whenever possible, contracts are awarded under full and open competition.
