Viasat has been selected by Lockheed Martin to provide high-bandwidth satellite communications technology for the National Oceanic and Atmospheric Administration’s (NOAA) next-generation fleet of C-130J Hercules “Hurricane Hunter” aircraft.
Advancing Airborne Environmental Monitoring
Operating under a subcontract through its Communication Services segment, Viasat will support the initial delivery of two specially modified C-130J vehicles, while the prime contract includes options for additional aircraft. These next-generation aircraft are scheduled to enter operational service by 2030, at which point they will replace legacy platforms and significantly enhance NOAA’s ability to gather mission-critical atmospheric data.
The aircraft will function as airborne laboratories, gathering vital environmental intelligence in extreme operating environments to improve hurricane forecasting and severe weather prediction. According to NOAA, access to this aircraft data substantially improves hurricane tracking and intensity forecasts, highlighting the importance of resilient airborne connectivity for the agency’s mission and the impact of real-time communications on emergency evacuations.
Integrating Hybrid SATCOM Technology
Viasat is tasked with providing engineering support, terminal hardware, and structural integration data to enable high-capacity satellite connectivity onboard the C-130J platform. The solution is intended to support the real-time transmission of both scientific and operational data collected during reconnaissance missions tracking hurricanes and tropical cyclones. This program represents the very first formal line-fit integration of Viasat’s Hybrid SATCOM Approach (HSA) technology onto the C-130J platform, establishing a factory-integrated connectivity solution designed to reduce the time, cost, and risk traditionally associated with post-delivery aircraft modifications.
Victor Farah, Senior Vice President of Government Services and Solutions at Viasat, Stated, “The selection validates the company’s open-architecture approach to resilient airborne communications and helps futureproof the aircraft for evolving mission requirements. To date, hundreds of C-130J models have been delivered and certified by 20 airworthiness authorities to support diverse, multi-mission global operations“.
Futureproofing Aerial Connectivity
The specialized configuration for NOAA will integrate HSA’s ARINC 791/792-compliant antenna baseplate alongside Viasat’s Ku/Ka broadband antenna system. This creates a standardized foundation and structure that supports robust mechanical integration immediately while also allowing for seamless technological upgrades in the future.
Although NOAA’s current application focuses specifically on Ku-band connectivity, the open and modular baseplate architecture will enable the C-130J aircraft to support future enhancements without requiring any structural rework. These potential enhancements include the ability to connect to additional frequency bands and multiple satellite constellations as network architectures evolve. This scalable approach aligns with the growing demand for resilient, high-capacity communications to support scientific research and emergency response missions worldwide.
