The US Air Force Research Laboratory (AFRL) says it has begun early research into a miniature air-to-air missile that would be carried on the next-generation of advanced fighter jets.
Known as the Small Advanced Capabilities Missile (SACM), AFRL officials say the conceptual missile would be far smaller and cheaper than today’s advanced air-to-air missiles like the Raytheon AIM-9X and AIM-120D, and therefore might be purchased and fielded in greater quantities.
SACM is one of many next-generation munitions concepts being pursued by AFRL as the US Air Force matures its so-called sixth-generation or air dominance fighter jet that would be introduced in the 2030s.
“SACM would be an affordable, highly lethal air-to-air missile with reduced size and weight compared to current air-to-air missiles,” AFRL tell Flightglobal in a prepared statement.
“By enabling a high loadout capability and increased missile effectiveness, future fighters would be able to survive in the contested anti-access/area-denial environment and complete their missions with minimal losses.”

AFRL is also looking at the next-generation of general purpose bombs known as GBU-X, and a powered air-to-ground missile (AGM-X) the would be rocket boosted for greater range and impact energy. GBU-X and AGM-X would also be “distributed, collaborative and cooperative” weapons for net-enabled, coordinated attacks on high-value targets.
Other concepts presented at the Air Force Association’s Air Warfare Symposium in Orlando, Florida this week include hypersonic boost-glide and scramjet-powered missiles pursued in the High-Speed Strike Weapon (HSSW) programme. According to fact sheets by AFRL, those weapons could be also wirelessly linked for coordinated attacks on integrated air defence systems.

AFRL is also focused on earth and concrete penetrators to attack reinforced underground facilities.
One option being considered was the rocket-boosted High-Velocity Penetrating Weapon (HVPW), although laboratory officials haven’t seen that project move forward since their technology demonstrations wrapped up.
Air Combat Command director of operations Maj Gen Thomas Deale, during a panel on close air support, called for every platform to carry more low collateral damage weapons with precision targeting and effects.
His ideal close air support platform would carry 3,000 to 4,000 rounds of ammunition and bombs that can be used reliably in close proximity to friendly forces in urban areas. “We need deeper magazines,” he says, adding that laser weapons with an unlimited amount of shots might someday solve that issue.
Missile experts at the Raytheon Co. are researching how to increase capabilities for next-generation air-launched tactical missiles under terms of a potential $14 million contract.
Officials of the munitions directorate of the U.S. Air Force Research Laboratory at Eglin Air Force Base, Fla., are asking researchers at the Raytheon Missile Systems segment in Tucson, Ariz., to increase the number of missiles carried on a single military aircraft sortie, increase the effectiveness of each missile, and enhance the platform survivability against all threats in an anti-access, area denial (A2AD) environment.
Specifically, the Air Force as asking Raytheon to conduct additional research and development on the Small Advanced Capability Missile (SACM) and Miniature Self-Defense Munition (MSDM) concepts.
The SACM will support affordable, highly lethal, small size and weight ordnance with advanced air frame design and synergistic control capabilities for air dominance enabling high air-to-air load-out, Air Force researchers say.
The SACM project seeks to provide flexible hyper-agile airframes, high impulse propulsion, affordable wide field of view seeker, anti-jam guidance integrated fuze, and aimable kinetic and non-kinetic effects.
The MSDM, meanwhile, will support miniaturized weapon capabilities for air superiority by enabling close-in platform self-defense and penetration into contested A2AD environment with little to no impact to payload capacity.
The MSDM seeks to develop an affordable guidance system for a future air-to-air munition designed for aircraft self-defense. The project will develop a conceptual design for the optics and algorithms of an affordable seeker front end for an air-to-air weapon for aircraft self-defense.
The program involves aerodynamics, propulsion, warhead, and the seeker front end. Cost is a primary driver. Raytheon experts will define system and subsystem requirements, explore design trades between subsystems and critical components, identify design risks, as well as model the launch aircraft, the miniature self-defense munition, and two threats.
On this contract Raytheon will do the work in Tucson, Ariz., and should be finished by January 2021.
