Intercept: Most systems can be used in different phases of ballistic missile flight, i.e., boost [73] (where surface or air-launched anti-aircraft missiles might also be effective because the ballistic missile is moving relatively slowly at low altitude), requiring proximity to the launch site and immediate response, mid-course/exo-atmospheric ...
Personnel Armor System for Ground Troops (PASGT, pronounced / ˈ p æ z ɡ ə t / PAZ-gət) is a combat helmet and ballistic vest that was used by the United States military from the early 1980s until the early or mid-2000s, when the helmet and vest were succeeded by the Lightweight Helmet (LWH), Modular Integrated Communications Helmet (MICH), and Interceptor body armor (IBA) respectively.
Non-ballistic atmospheric entry is a class of atmospheric entry trajectories that follow a non-ballistic trajectory by employing aerodynamic lift in the high upper atmosphere. It includes trajectories such as skip and glide. [1] [2] Skip is a flight trajectory where the spacecraft goes in and out the atmosphere.
Ablative armor is armor which prevents damage through the process of ablation, the removal of material from the surface of an object by vaporization, chipping, or other erosive processes. In contemporary spacecraft, ablative plating is most frequently seen as an ablative heat shield for a vehicle that must enter atmosphere from orbit, such as ...
In contrast to ballistic body armors, which usually focus on protecting the torso and head, a bomb suit must protect all parts of the body, since the dangers posed by a bomb's explosion affect the entire body. Parts of the bomb suit overlap for maximum protection. The suit protects in several different ways.
The lighter weight and non-ballistic nature of these helmets allowed the fitting of additional accessories without putting undue strain on the neck or requiring the drilling of holes through Kevlar to affix night vision mounting brackets, compromising the Kevlar helmet's protective ability if not done precisely.
Measuring the ballistic performance of armor is based on determining the kinetic energy of a bullet at impact (E k = 1 ⁄ 2 mv 2). Because the energy of a bullet is a key factor in its penetrating capacity, velocity is used as the primary independent variable in ballistic testing.
The High Risk Modular (HRM) tactical vest is a body armour used by the LAPD SWAT teams, [1] [2] NYPD ESU and the United States Marine Corps The vest was manufactured by Point Blank Body Armour and was issued from 1987 to 2006 when it was replaced by a standard III-A Soft armor vest.
