The War Zone, a website specializing in military affairs, reported that a US B-52 strategic bomber was spotted carrying prototypes of new AGM-181A cruise missiles.
The website also stated that these missiles are intended to be equipped with nuclear warheads.
Photographer Jarrod Hamilton posted photos on Instagram of the aircraft flying in the skies over the Mojave Desert in California, where test flights are usually conducted from Edwards Air Force Base.
The images show two missiles or prototypes hanging under the left wing of the aircraft, one painted dark gray, while the other has gray, black and orange markings on its side.
These missiles were designed to carry advanced W80-4 fusion warheads.
The Pentagon had originally planned for the missile's combat version to be ready by 2030, with the B-52H and B-21 bombers serving as its carriers.
