The 49th Test and Evaluation Squadron partnered with Small Business Innovation Research (SBIR) contractors to improve the communication capabilities in the B-52 Stratofortress. This event culminated in a June 29, 2021 demonstration that connected the B-52 to the International Marine/Maritime Satellite (INMARSAT) constellation with the ultimate goal of fielding this commercial off the shelf (COTS) system with an Iridium Certus terminal.
