A U.S. B-52H Stratofortress in a test-aircraft paint scheme was photographed carrying a pair of mysterious stores under its wing — weapons that may be the new AGM-181A Long-Range Stand-Off (LRSO) nuclear cruise missile, appearing as a subtle response to russian boasts about nuclear-powered Burevestnik, Poseidon systems.
The photographs were taken by Instagram user lookunderocks and shared with The Aviationist. According to the spotter, he was engaged in routine aircraft spotting in the Owens Valley when the strategic bomber passed overhead.

Mounted on a Multiple Ejector Rack (MER) — which can hold up to six munitions — were two unidentified weapons featuring inverted T-tails, fold-out wings beneath the fuselage, and a wedge-shaped profile at both the nose and tail.
At first glance, they could be AGM-154 Joint Stand-Off Weapons (JSOWs), but several details don't match: the nose shape, partial wing fairings, and cruciform tail surfaces differ from known JSOW variants.
The unknown stores instead bear a striking resemblance to the only publicly released image of the alleged stealthy, nuclear-capable AGM-181A LRSO and its carriage configuration.
There are differences between the photograph and the render, for example, the latter lacks a visible air intake, but this could easily be explained by classification or an intent to conceal specific capabilities. Public reports indicate that the LRSO uses a jet or ramjet propulsion system, making the presence of an intake on the operational version entirely plausible.
Another interesting possibility is that the bomber's flight was intended as a quiet demonstration. It's conceivable that the aircrew deliberately flew over known spotting locations — a subtle display of strength in response to russia's nuclear theatrics.
Development of the AGM-181A began in 2020, with Raytheon selected as the prime contractor. By 2022, reports indicated that the missile had undergone multiple B-52H test flights — including as many as nine captive-carry and separation trials — and successfully demonstrated clean release from the aircraft.
In addition to the proven B-52H, the LRSO is also planned to serve as a principal standoff weapon for the next-generation B-21 stealth bomber. Notably, the LRSO is designed exclusively for nuclear use — no conventional variant has been reported.
What exactly appears in the photograph remains unconfirmed, and no independent verification has surfaced. Still, given the timing and design similarities, the possibility that these are indeed AGM-181A LRSOs appears highly credible.
