Boeing Unveils Roadmap for Sustainable Aviation Fuel in Military Aircraft
“No Technical Objection” paves the path for Sustainable Aviation Fuel (SAF) implementation at sanctioned blending ratios on Boeing-manufactured military aircraft
Boeing has issued recommendations to defense clients indicating that aircraft produced by the company can function on sustainable aviation fuel (SAF) at presently authorized levels of up to 50% blend with traditional fuels. The announcement, made at RIAT, seeks to assist global military forces considering the integration of SAF into their fleets.
The global No Technical Objection (NTO) indicates there are no technical complications with Boeing defense aircraft operating on synthetic aviation turbine fuels, which encompass SAF. The NTO is applicable to all Boeing-manufactured defense aircraft and their variations.
“SAF is broadly recognized today as a compatible alternative that integrates seamlessly with existing aircraft, offering opportunities for international interoperability and strategic resilience through localized fuel production,” stated Steve Parker, senior vice president and chief operating officer at Boeing Defense, Space and Security. “We anticipate this NTO will facilitate more extensive SAF adoption among our military clients and foster greater synchronization between commercial and military fuel standards, benefiting all parties involved.”
Unblended, or “neat” SAF, which is entirely devoid of fossil fuels, can significantly lower lifecycle carbon emissions by up to 84% in comparison to traditional jet fuel and presents the industry’s greatest potential to reduce carbon footprints across all aviation sectors over the next three decades.
At present, the highest permissible levels for SAF involve a 50-50 blend with conventional fossil fuels.
Synthetic aviation turbine fuels are generated via alternative processes from resources other than petroleum. SAF is one category of synthetic fuels and utilizes recycled carbon from renewable sources such as waste oils, municipal solid waste, and agricultural residues.
SAF is a completely certified fuel source that is entirely interchangeable with conventional fuels like Jet A or Jet A-1. Moreover, several SAFs have been incorporated into military fuel specifications, including JP-8/NATO F-34 or JP-5/NATO F-44.
“Valid synthetic aviation turbine fuels, which includes SAF, enhance the DOD’s operational capabilities and are crucial for Navy readiness,” said Rick Kamin, Operational Energy Manager for the U.S. Naval Air Systems Command and head of the Tri-Service Petroleum, Oil, and Lubricants Users Group’s synthetic aviation turbine fuels qualification team. “The global NTO promotes the swift approval of synthetic aviation turbine fuels by the U.S. Department of Defense, essential for ensuring worldwide interoperability.”
Boeing has been at the forefront of making SAF a reality and has a longstanding history of promoting alternative fuels. In 2010, the company partnered with the U.S. Air Force on a comprehensive fuel study as part of their initiative to certify the C-17 Globemaster for SAF blends. That same year, Boeing also endorsed the supersonic flight of a U.S. Navy F/A-18F “Green Hornet” using a 50/50 SAF blend.
