Ukraine and weapons of mass destruction
From Wikipedia, the free encyclopedia
Ukraine, formerly a republic of the Union of Soviet Socialist Republics (USSR) from 1922–1991, once hosted Soviet nuclear weapons and delivery systems on its territory.[1] The former Soviet Union had its nuclear program expanded to only four of its republics: Belarus, Kazakhstan, Russia, and Ukraine. After its dissolution in 1991, Ukraine became the third largest nuclear power in the world and held about one third of the former Soviet nuclear weapons, delivery system, and significant knowledge of its design and production.[2] Ukraine inherited about 130 UR-100N intercontinental ballistic missiles (ICBM) with six warheads each, 46 RT-23 Molodets ICBMs with ten warheads apiece, as well as 33 heavy bombers, totaling approximately 1,700 nuclear warheads remained on Ukrainian territory.[3]
While all these weapons were located on Ukrainian territory, Russia controlled the launch sequence and maintained operational control of the nuclear warheads and its weapons system.[4] In 1994, Ukraine agreed to transfer these weapons to Russia and became a party to the Treaty on the Non-Proliferation of Nuclear Weapons, in exchange for assurances from Russia, the United States and United Kingdom to respect the Ukrainian independence and sovereignty in the existing borders.[5][6] The decision by Ukraine to give up the nuclear weapons was debated when Russia, one of the parties of the agreement, invaded Ukraine.
