Project Excalibur was a Lawrence Livermore National Laboratory (LLNL) Cold War–era research program to develop an X-ray laser system as a ballistic missile defense (BMD) for the United States. The concept involved packing large numbers of expendable X-ray lasers around a nuclear device, which would orbit in space.
A ballistic missile is a type of missile that uses projectile motion to deliver warheads on a target. These weapons are powered only during relatively brief periods—most of the flight is unpowered. These weapons are powered only during relatively brief periods—most of the flight is unpowered.
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. [3] [4] It is slated to replace all 450 Minuteman III missiles from 2029 through 2075. The Minuteman missiles are currently stationed in ...
Missile defense is a system, weapon, or technology involved in the detection, tracking, interception, and also the destruction of attacking missiles.Conceived as a defense against nuclear-armed intercontinental ballistic missiles (ICBMs), its application has broadened to include shorter-ranged non-nuclear tactical and theater missiles.
The basic paradigm used for this purpose is a divert and attitude control system (DACS), with four divert thrusters and six attitude control nozzles attached to the KV. [8] This kind of design is found in many anti-missile and anti-satellite weapons, including the RIM-161 Standard Missile 3 [9] and THAAD. [10]
The United States was the first country to attempt to establish a space-based early warning system. The goal was to detect Soviet ballistic missile launches and give 20 to 33 minutes notice of the missile's arrival (against 10 to 25 minutes for the BMEWS ground-based radar network).
The US Army started their first serious efforts in the anti-ballistic missile arena when they asked the Bell Labs missile team to prepare a report on the topic in February 1955. The Nike team had already designed the Nike Ajax system that was in widespread use around the US, as well as the Nike Hercules that was in the late stages of ...
A penetration aid (or "penaid") is a device or tactic used to increase an aircraft's capability of reaching its target without detection, and in particular intercontinental ballistic missile (ICBM) warhead's chances of penetrating a target's defenses. [1]
