Ground Based Strategic Deterrent
The LGM-35 Sentinel, also known as the Ground Based Strategic Deterrent (GBSD), is a land-based intercontinental ballistic missile (ICBM) system under development for the United States Air Force. It is intended to replace all 450 LGM-30 Minuteman, Minuteman III missiles beginning in 2029, with service expected through 2075. The Minuteman III missiles are currently deployed in North Dakota, Wyoming, Montana, and Nebraska. In 2020, the Department of the Air Force awarded Northrop Grumman a sole-source contract to develop the Sentinel after Boeing withdrew from the bidding process. Subcontractors include Lockheed Martin, General Dynamics, Bechtel, Honeywell, Aerojet Rocketdyne, Parsons Corporation, Parsons, Textron, and others.

Nuclear Triad
A nuclear triad is a three-pronged military force structure of land-based intercontinental ballistic missiles (ICBMs), submarine-launched ballistic missiles (SLBMs), and strategic bombers with Nuclear weapon, nuclear bombs and missiles. Countries build nuclear triads to eliminate an enemy's ability to destroy a nation's nuclear forces in a Pre-emptive nuclear strike, first-strike attack, which preserves their own ability to launch a second strike and therefore increases their nuclear deterrence. Four countries are known to have complete nuclear triad: United States, the United States, Russia, India, and China. Israel is suspected to possess a nuclear triad, but its status is not confirmed. France and Pakistan are considered partial triad powers. Components of a strategic nuclear triad While traditional nuclear strategy holds that a nuclear triad provides the best level of deterrence from attack, most nuclear powers do not have the military budget to sustain a full triad.

Missile
A missile is an airborne ranged weapon capable of self-propelled flight aided usually by a propellant, jet engine or rocket motor. Historically, 'missile' referred to any projectile that is thrown, shot or propelled towards a target; this usage is still recognized today with any unguided jet- or rocket-propelled weapons generally described as rocket artillery. Airborne explosive devices without propulsion are referred to as shells if fired by an artillery piece and bombs if dropped by an aircraft. Missiles are also generally guided towards specific targets termed as guided missiles or guided rockets. Missile systems usually have five system components: targeting, guidance system, flight system, engine, and warhead. Missiles are primarily classified into different types based on firing source and target such as surface-to-surface, air-to-surface, surface-to-air and air-to-air missiles. Terminology Missile is derived from Latin "missilis" meaning "that may be ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Surface-to-surface Missile
A surface-to-surface missile (SSM) is a missile designed to be launched from the ground or the sea and strike targets on land or at sea. They may be fired from hand-held or vehicle mounted devices, from fixed installations, or from a ship. They are often powered by a rocket engine or sometimes fired by an explosive charge, since the launching platform is typically stationary or moving slowly. They usually have fins and/or wings for lift and stability, although hyper-velocity or short-ranged missiles may use body lift or fly a ballistic trajectory. The first operational surface-to-surface missile was the V-1 flying bomb, it was powered by a pulsejet engine. Contemporary surface-to-surface missiles are usually guided. An unguided surface-to-surface missile is usually referred to as a rocket (for example, an RPG-7 or M72 LAW is an anti-tank rocket), whereas a BGM-71 TOW or AT-2 Swatter is an anti-tank guided missile. Examples of surface-to-surface missile include the MGM-140 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
