A U-30 Aircraft Tow Tractor is positioned to tow a KC-135 Stratotanker assigned to the Hawaii Air National Guard 203rd Air Refueling Squadron, July 18, 2019, Joint Base Pearl Harbor-Hickam. The tow tractor was powered by hydrogen fuel cells and was part of a demonstration on the capabilities of hydrogen fuel cell technology to power some Airforce operations. The Air Force Research Laboratory on behalf of the Hawaii Center for Advanced Transportation Technologies conducted a demonstration towing on the Stratotanker utilizing a hydrogen fuel cell powered tug. This was the first tug demonstration on a large U.S. Air Force aircraft using the hydrogen fuel cell equipment. The project is a proof of concept demonstration to validate hydrogen vehicle technologies in supporting Air Force mission requirements. (U.S. Air National Guard photo by Tech. Sgt.
