The MIM-104 Patriot is a mobile interceptor missile surface-to-air missile (SAM) system, the primary such system used by the United States Army and several allied states. It is manufactured by the U.S. defense contractor Raytheon and derives its name from the radar component of the weapon system.
Equal-area Mick Dyer: Cylindrical equal-area projection with standard parallels at 37.5°N/S and an aspect ratio of 1.977. Similar are Trystan Edwards with standard parallels at 37.4° and Smyth equal surface (=Craster rectangular) with standard parallels around 37.07°. 1855 Gall–Peters = Gall orthographic = Peters: Cylindrical Equal-area ...
Trophy is a system that enables connectivity to other technologies, such as soft-kill, C4I systems, remote-controlled weapons stations, etc. The system is designed to defend against many types of anti-tank guided missiles , rockets, and high-explosive anti-tank (HEAT) rounds, shoulder launched weapons such as rocket propelled grenades and ...

An acute triangle (or acute-angled triangle) is a triangle with three acute angles (less than 90°). An obtuse triangle (or obtuse-angled triangle) is a triangle with one obtuse angle (greater than 90°) and two acute angles. Since a triangle's angles must sum to 180° in Euclidean geometry, no Euclidean triangle can have more than one obtuse ...
A Ukrainian defense initiative is making steel armor plates to wrap around the control unit of the Patriot battery.
Fearing China will deploy hypersonic weapons to sink ships in the Pacific, the U.S. Navy is moving forward with a plan to arm some of its vessels with Patriot interceptor missiles, two senior ...
The summit angles of a Saccheri quadrilateral are acute if the geometry is hyperbolic, and right angles if the geometry is Euclidean. The sum of the measures of the angles of any triangle is less than 180° if the geometry is hyperbolic, and equal to 180° if the geometry is Euclidean.
