It played various roles through the decades, including bomber operations in World War II and Cold War missions. In its modern incarnation, the 49th TES is primarily responsible for operational testing and evaluation of advanced bomber aircraft, such as the B-52 Stratofortress and B-1 Lancer, ensuring these platforms meet combat readiness standards.
