Militarisation of outer space – selected problems

This article aims at indicating a significant problem from the point of view of international security, i.e. militarisation of outer space and the ongoing race for domination with the participation of the United States, the Russian Federation, China and India. The ongoing development of military resources in the outer space and the existing gaps in the international law regulations concerning space law result in the fact that the concept of the cosmic theatre of war is gradually realised. One of the biggest challenges that are contemporarily faced by the international security is the proliferation of missile technology, especially in those countries that are seeking to obtain a favourable regional geopolitical position or aspiring to become supra-regional leaders. Missile defence system consists of four inter-related and complementary elements: land, sea, air and outer space.
