The AGM-181 Long Range Stand Off Weapon (LRSO) is a nuclear-armed air-launched cruise missile under development by Raytheon Technologies that will replace the AGM-86 ALCM.
As of August 24, 2017, Raytheon and Lockheed Martin received separate $900 million contracts from the Department of Defense and US Air Force and are developing their own versions. [2] [3] [4] Contracts were intended to end in 2022, when the Department of Defense will select one design to continue further developments. [5]
To replace the ALCM, the USAF planned to award a contract for the development of the new Long-Range Stand-Off weapon in 2015. [6] Unlike the AGM-86, the LRSO will be carried on multiple aircraft. The LRSO program is to develop a weapon that can penetrate and survive integrated air defense systems and prosecute strategic targets. The weapons are required to reach initial operational capability (IOC) before the retirement of their respective ALCM versions, around 2030. [7]
The technology development contracts were to be submitted before the end of 2012. [8] In March 2014 a further three-year delay in the project was announced by the Department of Defense, delaying a contract award until fiscal year 2018. [9] The House Armed Services Committee moved to reject this delay. [10] The delay was caused by financial pressures and an uncertain acquisition plan, and allowed by the long remaining service life left for the AGM-86 and lack of urgent necessity compared to other defense needs. [11] The designations YAGM-180A and YAGM-181A have been allocated to the LRSO prototypes from Lockheed Martin and Raytheon Technologies respectively. [12] The FY2020 defense authorization bill passed by Congress repealed the requirement for a conventional warhead version of the LRSO, leaving only the nuclear armed variant. The Air Force will use the JASSM-ER and the longer-ranged JASSM-XR to fulfill the conventional standoff missile role. [13]
In April 2020, the Air Force announced plans to continue the Long-Range Standoff Weapon’s development with Raytheon Company as a sole-source contractor. [14]
On 1 July 2021, the USAF awarded Raytheon a cost-plus-fixed-fee contract for the engineering and manufacturing development stage of the LRSO program, with options that could take the contract to about US$2 billion. DefenseNews reported that the USAF could buy more than 1,000 AGM-181 missiles, which are projected to have a range in excess of 1,500 miles (2,400 km). [15]
The AGM-181 will be integrated with the B-52H and B-21 bomber. [16] The missile's nuclear warhead will be the W80-4 warhead. [17] [18] [19]

The AGM-88 HARM is a tactical, air-to-surface anti-radiation missile designed to home in on electronic transmissions coming from surface-to-air radar systems. It was originally developed by Texas Instruments as a replacement for the AGM-45 Shrike and AGM-78 Standard ARM system. Production was later taken over by Raytheon Corporation when it purchased the defense production business of Texas Instruments.
The AGM-65 Maverick is an air-to-ground missile (AGM) designed for close air support. It is the most widely produced precision-guided missile in the Western world, and is effective against a wide range of tactical targets, including armor, air defenses, ships, ground transportation and fuel storage facilities.
A cruise missile is an unmanned self-propelled guided vehicle that sustains flight through aerodynamic lift for most of its flight path and whose primary mission is to place an ordnance or special payload on a target. Cruise missiles are designed to deliver a large warhead over long distances with high precision. Modern cruise missiles are capable of traveling at high subsonic, supersonic, or hypersonic speeds, are self-navigating, and are able to fly on a non-ballistic, extremely low-altitude trajectory.
The AGM-154 Joint Standoff Weapon (JSOW) is a glide bomb that resulted from a joint venture between the United States Navy and Air Force to deploy a standardized medium range precision guided weapon, especially for engagement of defended targets from outside the range of standard anti-aircraft defenses, thereby increasing aircraft survivability and minimizing friendly losses. It is intended to be used against soft targets such as parked aircraft, trucks, armored personnel carriers (APCs), and surface-to-air missile sites (SAMs). Prior to launch, it is given a destination through either a predesignated waypoint or a point marked through a targeting pod. It glides, using two wings that pop out for added lift, to the marked destination and dispenses submunitions in a short, roughly linear pattern. The designation of the Joint Standoff Weapon as an "air-to-ground missile" is a misnomer, as it is an unpowered bomb with guidance avionics, similar to the older GBU-15.
The AGM-86 ALCM is an American subsonic air-launched cruise missile (ALCM) built by Boeing and operated by the United States Air Force. This missile was developed to increase the effectiveness and survivability of the Boeing B-52H Stratofortress strategic bomber. The missile dilutes an enemy's forces and complicates air defense of its territory.
An air-to-surface missile (ASM) or air-to-ground missile (AGM) is a missile designed to be launched from military aircraft at targets on land or sea. There are also unpowered guided glide bombs not considered missiles. The two most common propulsion systems for air-to-surface missiles are rocket motors, usually with shorter range, and slower, longer-range jet engines. Some Soviet-designed air-to-surface missiles are powered by ramjets, giving them both long range and high speed.
The AGM-129 ACM was a low-observable, subsonic, turbofan-powered, air-launched cruise missile originally designed and built by General Dynamics and eventually acquired by Raytheon Missile Systems. Prior to its withdrawal from service in 2012, the AGM-129A was carried exclusively by the US Air Force's B-52H Stratofortress bombers.
The W80 is a low to intermediate yield two-stage thermonuclear warhead deployed by the U.S. enduring stockpile with a variable yield ("dial-a-yield") of 5 or 150 kilotonnes of TNT.
The Northrop AGM-137 TSSAM was a standoff cruise missile developed for the three branches of the United States Armed Forces, hence "tri-service". Missile development began in 1986 but revelation of cost-overruns in 1991 prompted the Army to pull out of the project and an investigation of the procurement process by the General Accounting Office. The TSSAM program was eventually cancelled in December 1994 pursuant to a GAO recommendation and the loss of support of the United States Army after going as far as several test launches.
The Popeye is a family of air-to-surface missiles developed and in use by Israel, of which several types have been developed for Israeli and export users. A long-range submarine-launched cruise missile variant of the Popeye Turbo has been speculated as being employed in Israel's submarine-based nuclear forces. The United States operated the Popeye under a different designation according to US naming conventions as the AGM-142 Have Nap.
The AGM-158 JASSM is a low detection standoff air-launched cruise missile developed by Lockheed Martin for the United States Armed Forces. It is a large, stealthy long-range weapon with a 1,000-pound (450 kg) armor piercing warhead. It completed testing and entered service with the U.S. Air Force in 2009, and has entered foreign service in Australia, Finland, and Poland as of 2014. An extended range version of the missile, the AGM-158B JASSM-ER, entered service in 2014 as well as an anti-ship derivative, the AGM-158C LRASM, in 2018. By September 2016, Lockheed Martin had delivered 2,000 total JASSMs comprising both variants to the USAF.
Standoff weapons are missiles or bombs which may be launched from a distance sufficient to allow attacking personnel to evade the effect of the weapon or defensive fire from the target area. Typically, they are used against land- and sea-based targets in an offensive operation. The name is derived from their ability to engage the target while standing off outside the range at which the defenders are likely to engage the attacker. Typical stand-off weapons include cruise missiles, glide bombs and short-range ballistic missiles.
The Counter-electronics High Power Microwave Advanced Missile Project (CHAMP) is a joint concept technology demonstration led by the Air Force Research Laboratory, Directed Energy Directorate at Kirtland Air Force Base to develop an air-launched directed-energy weapon capable of incapacitating or damaging electronic systems by means of an EMP.
The AGM-158C LRASM is a stealth air launch anti-ship cruise missile developed for the United States Air Force and United States Navy by the Defense Advanced Research Projects Agency (DARPA). Derived from the AGM-158B JASSM-ER, the LRASM was intended to pioneer more sophisticated autonomous targeting capabilities than the U.S. Navy's current Harpoon anti-ship missile, which has been in service since 1977.
The Ra'ad, is a subsonic, standoff, and an air-launched cruise missile (ALCM) designed and jointly developed by the National Engineering & Scientific Commission (NESCOM) and Pakistan Air Force's Air Weapons Complex.
The SOM is a next-generation autonomous, stealth, high precision air-launched cruise missile developed by TÜBİTAK SAGE, Defence Research and Development Institute of Turkey. It was first revealed during the 100th anniversary celebrations of the Turkish Air Force at the Çiğli Air Base in İzmir, on 4 June 2011. Developed since 2006, the SOM is Turkey's first domestic guided missile for striking both stationary and moving targets at a stand-off distance of over 180 kilometers. Although being developed by TÜBİTAK SAGE which still holds authority over the design of the missile, ROKETSAN has been given the role of manufacturing and marketing the missile for export.
An air-launched cruise missile (ALCM) is a cruise missile that is launched from a military aircraft. Current versions are typically standoff weapons which are used to attack predetermined land targets with conventional, nuclear or thermonuclear payloads.
The Ra'ad-II is a standoff and an air-launched cruise missile (ALCM) derived from the Hatf-VIII Ra'ad. It was first publicly unveiled on the Pakistan Day Parade on 23 March 2017,
The AGM-183 ARRW is a hypersonic air-to-ground ballistic missile planned for use by the United States Air Force. Developed by Lockheed Martin, the boost-glide vehicle is propelled to a maximum speed of more than Mach 5 by a rocket motor before gliding toward its target. The program was cancelled in March 2023 after multiple failed tests. The program, however, continued despite the cancellation and was announced to still be in development following additional, undisclosed testing.
Rapid Dragon is a palletized and disposable weapons module which is airdropped in order to deploy flying munitions, typically cruise missiles, from unmodified cargo planes. Developed by the United States Air Force and Lockheed, the airdrop-rigged pallets, called "deployment boxes," provide a low cost method allowing unmodified cargo planes, such as C-130 or C-17 aircraft, to be temporarily repurposed as standoff bombers capable of mass launching any variant of long or short range AGM-158 JASSM cruise missiles against land or naval targets.
