The Stand-in Attack Weapon (SiAW) is a tactical air-to-surface missile under development for the United States Air Force (USAF) by Northrop Grumman.
It is primarily designed to attack air-defences and high-value targets such as command-and-control sites, surface-to-surface missile launchers, anti-satellite systems, and GPS jamming systems. [1]
In May 2022, the USAF awarded contracts to L3Harris Technologies, Lockheed Martin and Northrop Grumman to begin the first phase of development for the Stand-in Attack Weapon (SiAW). [3] On 28 September 2023, the USAF awarded a US$705m contract to Northrop Grumman to develop and test the SiAW. The SiAW is intended to attack relocatable targets including theater ballistic missile launchers, cruise and anti-ship missile launchers, GPS jamming platforms and anti-satellite systems. It will have a shorter range than standoff weapons, being fired by an aircraft after penetrating enemy airspace. The SiAW will fit inside the F-35 Lightning II's internal weapon bays. The design leverages work on the United States Navy's AGM-88G Advanced Anti-Radiation Guided Missile - Extended Range (AARGM-ER). The USAF plans to have an operational weapon by 2026. [4] [5]
In November 2024, Northrop Grumman delivered the first SiAW to the USAF for flight testing. [6] [7]
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 Northrop B-2 Spirit, also known as the Stealth Bomber, is an American heavy strategic bomber, featuring low-observable stealth technology designed to penetrate dense anti-aircraft defenses. A subsonic flying wing with a crew of two, the plane was designed by Northrop as the prime contractor, with Boeing, Hughes, and Vought as principal subcontractors, and was produced from 1987 to 2000. The bomber can drop conventional and thermonuclear weapons, such as up to eighty 500-pound class (230 kg) Mk 82 JDAM GPS-guided bombs, or sixteen 2,400-pound (1,100 kg) B83 nuclear bombs. The B-2 is the only acknowledged in-service aircraft that can carry large air-to-surface standoff weapons in a stealth configuration.
The Lockheed Martin F-35 Lightning II is an American family of single-seat, single-engine, supersonic stealth strike fighters. A multirole combat aircraft designed for both air superiority and strike missions, it also has electronic warfare and intelligence, surveillance, and reconnaissance capabilities. Lockheed Martin is the prime F-35 contractor with principal partners Northrop Grumman and BAE Systems. The aircraft has three main variants: the conventional takeoff and landing (CTOL) F-35A, the short take-off and vertical-landing (STOVL) F-35B, and the carrier variant (CV) catapult-assisted take-off but arrested recovery (CATOBAR) F-35C.
The Joint Direct Attack Munition (JDAM) is a guidance kit that converts unguided bombs, or "dumb bombs", into all-weather precision-guided munitions (PGMs). JDAM-equipped bombs are guided by an integrated inertial guidance system coupled to a Global Positioning System (GPS) receiver, giving them a published range of up to 15 nautical miles (28 km). JDAM-equipped bombs range from 500 to 2,000 pounds. The JDAM's guidance system was jointly developed by the United States Air Force and United States Navy, hence the "joint" in JDAM. When installed on a bomb, the JDAM kit is given a GBU identifier, superseding the Mark 80 or BLU nomenclature of the bomb to which it is attached.
Northrop Grumman Corporation is an American multinational aerospace and defense company. With 95,000 employees and an annual revenue in excess of $30 billion, it is one of the world's largest weapons manufacturers and military technology providers. The firm ranked No. 101 on the 2022 Fortune 500 list of America's largest corporations.
The Northrop/McDonnell Douglas YF-23 is an American single-seat, twin-engine, stealth fighter technology demonstrator prototype designed for the United States Air Force (USAF). The design team, with Northrop as the prime contractor, was a finalist in the USAF's Advanced Tactical Fighter (ATF) demonstration/validation competition, battling the YF-22 team for full-scale development and production. Two YF-23 prototypes were built.
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-52G and B-52H Stratofortress strategic bombers, allowing the aircraft to deliver its payload from a great distance. The missile dilutes an enemy's forces ability to respond and complicates air defense of its territory.
The GBU-57A/BMassive Ordnance Penetrator (MOP) is a precision-guided, 30,000-pound (14,000 kg) "bunker buster" bomb used by the United States Air Force. The GBU-57 is substantially larger than the deepest-penetrating bunker busters previously available, the 5,000-pound (2,300 kg) GBU-28 and GBU-37. Due to its size it can only be carried by large bombers—for instance, the B-2 Spirit.
The ADM-160 MALD is an air-launched, expendable decoy missile developed by the United States. Later variants (MALD-J) are additionally equipped with electronic countermeasures to actively jam early warning and target acquisition radars.
The AGM-158 Joint Air-to-Surface Standoff Missile 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. In August 2024 the US was reportedly considering supplying JASSM missiles to Ukraine.
A large number of variants of the General Dynamics F-16 Fighting Falcon have been produced by General Dynamics, Lockheed Martin, and various licensed manufacturers. The details of the F-16 variants, along with major modification programs and derivative designs significantly influenced by the F-16, are described below.
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 GBU-39/B Small Diameter Bomb (SDB) is a 250-pound (110 kg) precision-guided glide bomb that is intended to allow aircraft to carry a greater number of smaller, more accurate bombs. Most US Air Force aircraft will be able to carry a pack of four SDBs in place of a single 2,000-pound (910 kg) Mark 84 bomb. It first entered service in 2006. The Ground Launched Small Diameter Bomb (GLSDB) was later developed to enable the SDB to be launched from a variety of ground launchers and configurations.
The Long Range Strike Bomber (LRS-B) is a development and acquisition program to develop a long-range strategic bomber for the United States Air Force, intended to be a heavy-payload stealth aircraft that can deliver thermonuclear weapons. Initial capability is planned for the mid-2020s. A request for proposals to develop the aircraft was issued in July 2014. The Air Force plans to procure at least 100 and potentially up to 200 of the LRS-B aircraft for an estimated $550 million each. A development contract was awarded to Northrop Grumman for its B-21 Raider in October 2015. Much about the project is highly classified and little information is available to the public. As of late 2019, it was known that construction of the aircraft had begun, and on December 2, 2022, it was unveiled to the public.
The Northrop Grumman RQ-180 is an American stealth unmanned aerial vehicle (UAV) surveillance aircraft intended for contested airspace. As of 2019, there had been no images or statements released, but evidence points to the existence of the RQ-180 and its use in regular front-line service.
The Northrop Grumman B-21 Raider is an American strategic bomber in development for the United States Air Force (USAF) by Northrop Grumman. Part of the Long Range Strike Bomber (LRS-B) program, it is to be a stealth intercontinental strategic bomber that can deliver conventional and thermonuclear weapons. Named "Raider" in honor of the Doolittle Raiders of World War II, the B-21 is meant to replace the Rockwell B-1 Lancer and Northrop Grumman B-2 Spirit by 2040, and possibly the Boeing B-52 Stratofortress after that.
SPEAR is a family of air-launched effectors under development by MBDA UK for the Royal Air Force's Select Precision Effects At Range (SPEAR) Capability 3, or SPEAR 3 programme, from which the system also derives its name. The SPEAR family currently consists of two variants: SPEAR, a 100kg class air-to-surface cruise missile; and SPEAR-EW, an electronic warfare variant for stand-in jamming or for use as a decoy.
The LGM-35 Sentinel, also known as the Ground Based Strategic Deterrent (GBSD), is a future American land-based intercontinental ballistic missile system (ICBM) currently in the early stages of development. It is slated to replace all 450 Minuteman III missiles from 2029 through 2075. The Minuteman missiles are currently stationed in North Dakota, Wyoming, Montana, and Nebraska.
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. However in 2024 it was announced that in the fiscal year 2025 budget, no funding would be provided for procurement or further research and development.
The Hypersonic Attack Cruise Missile (HACM) is a scramjet-powered hypersonic air-launched cruise missile project, the successor of the Hypersonic Air-breathing Weapon Concept (HAWC) and the SCIFiRE hypersonic programs.
