Long-Range Stand-Off (LRSO) nuclear cruise missile enhances U.S. strategic deterrence with extended-range precision strike capability, replacing the AGM-86B and enabling survivable engagement of high-value targets from outside contested airspace. |
The United States is accelerating development of a new nuclear-armed cruise missile, called LRSO (Long-Range Stand-Off), to ensure its bombers can strike from beyond heavily defended airspace.
- This move strengthens the survivability and credibility of airborne nuclear deterrence against advanced adversaries with modern air defenses.
- The Long-Range Stand-Off nuclear cruise missile will replace the aging AGM-86B and allow U.S. bombers to deliver nuclear strikes without entering contested zones, expanding operational reach and flexibility.
- Announced on April 30, 2026, the effort supports broader nuclear modernization and reinforces deterrence in high-end conflict environments.
AGM-181 LRSO
The
AGM-181 Long Range Stand Off Weapon is a nuclear-armed air-launched
cruise missile under development by Raytheon Technologies that will
replace the AGM-86 ALCM. Unlike the AGM-86, which is solely carried by
the B-52H Stratofortress, the LRSO will be carried on the B-52, B-2
Spirit, and forthcoming B-21 Raider.

New Nuclear Bunker Buster Bomb Plans Revealed
A U.S. Air Force B-1B Lancer has been shown in flight carrying an AGM-183A ARRW hypersonic weapon, introducing a new potential launch configuration for American long-range strike operations.
The image is operationally important because it places a supersonic heavy bomber within the U.S. hypersonic strike architecture, offering commanders a faster standoff option against protected, time-sensitive targets.
- ARRW is designed to accelerate to hypersonic speed before releasing a maneuvering glide vehicle toward high-value land targets.
- Integrated with the B-1B’s speed, range, payload capacity, and standoff employment profile, the weapon could expand U.S. strike geometry against integrated air defenses, missile-support infrastructure, command-and-control nodes, and other critical military targets inside contested environments.
