The images, captured by photographer Ryan Watamura on November 5, 2025, show the bomber flying at high speed with an external pylon carrying the new weapon. This is the second time the missile has been seen attached to a B-52, reinforcing the ongoing integration and aerodynamic testing of the LRSO.

The AGM-181 was developed to replace the older AGM-86B, offering greater range, stealth, and survivability against modern air defenses. The missile will be compatible with the B-52 Stratofortress and B-21 Raider bombers, both nuclear-capable. As part of the Air Force’s extensive modernization program, the project also includes new engines, radars, and communication systems. Raytheon is the prime contractor, and flight tests have shown positive results since 2022.
Valued at around US$16 billion, the program envisions a gradual replacement of older missiles by 2030, with initial production expected to begin in 2027. The fact that the B-52 was seen operating with the new weapon under clear visibility conditions raises the possibility of a deliberate show of strength by the United States amid rising global strategic tensions.
