U.S. President Donald Trump's Golden Dome missile defense concept revives a controversial, decades-old initiative whose ambitious construction could upend norms in outer space and reshape relations between the world's top space powers.

If you were worried about the possibility of World War III, fear not: Donald Trump has announced plans to develop a "golden dome" missile defence system to keep the U.S. safe — and Stephen Colbert has thoughts.

India's integrated air defence system consolidates data from Army, Navy and the Air Force to intercept and take on aerial threats through the Integrated Air Command and Control System (IACCS).

Chuck DeVore, expert at Texas Public Policy Foundation, argued a decreased cost to orbit made it less expensive to defend against nuclear missiles than to build a bigger nuclear arsenal, with Golden Dome changing the game of homeland defenses.
