The Strategic Defense Initiative (SDI), was a proposed missile defense system intended to protect the United States from attack by ballistic nuclear missiles. The program was announced in 1983, by President Ronald Reagan. Reagan called for a system that would render nuclear weapons obsolete, and to end the doctrine of mutual assured destruction (MAD), which he described as a "suicide pact". Elements of the program reemerged in 2019 under the Space Development Agency (SDA).
Non-lethal weapons, also called nonlethal weapons, less-lethal weapons, less-than-lethal weapons, non-deadly weapons, compliance weapons, or pain-inducing weapons are weapons intended to be less likely to kill a living target than conventional weapons such as knives and firearms with live ammunition. It is often understood that unintended or incidental casualties are risked wherever force is applied, however non-lethal weapons minimise the risk of casualties as much as possible. Non-lethal weapons are used in policing and combat situations to limit the escalation of conflict where employment of lethal force is prohibited or undesirable, where rules of engagement require minimum casualties, or where policy restricts the use of conventional force. However, these weapons occasionally cause serious injuries or death due to allergic reactions, improper use and/or other factors; for this reason the term "less-lethal" has been preferred by some organizations as it describes the risks of death more accurately than the term "non-lethal", which some have argued is a misnomer.
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.
The Stryker is a family of eight-wheeled armored fighting vehicles derived from the Canadian LAV III, itself derived from the Swiss Mowag Piranha. Stryker vehicles are produced by General Dynamics Land Systems-Canada (GDLS-C) for the United States Army in a plant in London, Ontario. It has four-wheel drive (8×4) and can be switched to all-wheel drive (8×8).
Riot control measures are used by law enforcement, military, paramilitary or security forces to control, disperse, and arrest people who are involved in a riot, unlawful demonstration or unlawful protest.
A directed-energy weapon (DEW) is a ranged weapon that damages its target with highly focused energy without a solid projectile, including lasers, microwaves, particle beams, and sound beams. Potential applications of this technology include weapons that target personnel, missiles, vehicles, and optical devices.
The Air Force Research Laboratory (AFRL) is a scientific research and development detachment of the United States Air Force Materiel Command dedicated to leading the discovery, development, and integration of direct-energy based aerospace warfighting technologies, planning and executing the Air Force science and technology program, and providing warfighting capabilities to United States air, space, and cyberspace forces. It controls the entire Air Force science and technology research budget which was $2.4 billion in 2006.
Space warfare is combat in which one or more belligerents are in outer space. The scope of space warfare includes ground-to-space warfare, such as attacking satellites from the Earth; space-to-space warfare, such as satellites attacking satellites; and space-to-ground warfare, such as satellites attacking Earth-based targets. Space warfare in fiction is thus sub-genre and theme of science fiction, where it is portrayed with a range of realism and plausibility. In the real world, international treaties are in place that attempt to regulate conflicts in space and limit the installation of space weapon systems, especially nuclear weapons.
A dazzler is a non-lethal weapon which uses intense directed radiation to temporarily disorient its target with flash blindness. They can effectively deter further advances, regardless of language or cultural barriers, but can also be used for hailing and warning. Targets can include electronic sensors as well as human vision.
A guided bomb is a precision-guided munition designed to achieve a smaller circular error probable (CEP).
A laser weapon is a type of directed-energy weapon that uses lasers to inflict damage. Whether they will be deployed as practical, high-performance military weapons remains to be seen. One of the major issues with laser weapons is atmospheric thermal blooming, which is still largely unsolved. This issue is exacerbated when there is fog, smoke, dust, rain, snow, smog, foam, or purposely dispersed obscurant chemicals present. In essence, a laser generates a beam of light that requires clear air or a vacuum to operate.
The GBU-44/B Viper Strike glide bomb was a GPS-aided laser-guided variant of the Northrop Grumman Brilliant Anti-Tank (BAT) munition which originally had a combination acoustic and infrared homing seeker. The system was initially intended for use from UAVs, and it was also integrated with the Lockheed AC-130 gunship, giving that aircraft a precision stand-off capability. The Viper Strike design is now owned by MBDA.
Iron Dome is an Israeli mobile all-weather air defense system, developed by Rafael Advanced Defense Systems and Israel Aerospace Industries. The system is designed to intercept and destroy short-range rockets and artillery shells fired from distances of 4 to 70 kilometres (2–43 mi) away and whose trajectory would take them to an Israeli populated area. From 2011 to 2021, the United States contributed a total of US$1.6 billion to the Iron Dome defense system, with another US$1 billion approved by the US Congress in 2022.
A precision-guided munition (PGM), also called a smart weapon, smart munition, or smart bomb, is a guided munition intended to hit a specific target, to minimize collateral damage and increase lethality against intended targets. During the Persian Gulf War guided munitions accounted for only 9% of weapons fired, but accounted for 75% of all successful hits. Despite guided weapons generally being used on more difficult targets, they were still 35 times more likely to destroy their targets per weapon dropped.
The GBU-39/B Small Diameter Bomb (SDB) is a 250-pound (110 kg) precision-guided glide bomb that is intended to provide aircraft with the ability to carry a higher number of 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) 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.
Martlet or the Lightweight Multirole Missile(LMM) is a lightweight air-to-surface, air-to-air, surface-to-air, and surface-to-surface missile developed by Thales Air Defence for the United Kingdom. It is named after a mythical bird from English heraldry that never roosts, the Martlet.
The DF-ZF is a hypersonic glide vehicle (HGV) developed by the People's Republic of China. It is launched by the DF-17 medium-range ballistic missile. The combined weapon system was likely operational by October 2019.
Iron Beam, officially מגן אור, magen or, Shield of Light is a directed-energy weapon air defense system unveiled at the Singapore Airshow on February 11, 2014 by Israeli defense contractor Rafael Advanced Defense Systems. The system is designed to destroy short-range rockets, artillery, and mortar bombs; it has a range of up to 7 km (4.3 mi), complementing the Iron Dome system which was designed to intercept missiles launched from a greater distance. In addition, the system could also intercept unmanned aerial vehicles. Iron Beam will constitute the fifth element of Israel's integrated missile defense system, in addition to Arrow 2, Arrow 3, David's Sling and Iron Dome.
A loitering munition, also known as a suicide drone, kamikaze drone, or exploding drone, is a kind of aerial weapon with a built-in warhead that is typically designed to loiter around a target area until a target is located, then attack the target by crashing into it. Loitering munitions enable faster reaction times against hidden targets that emerge for short periods without placing high-value platforms near the target area and also allow more selective targeting as the attack can be changed mid-flight or aborted.
