SS-N-22 Sunburn is the NATO reporting name for two unrelated Soviet anti-ship missiles. Although the missiles were very different, distinguishing between them is difficult because their ship-mounted launching containers were identical. Confusion was exacerbated by the Soviet practice of mixing missile types within a class of ships. It was therefore not confirmed that the "SS-N-22" actually referenced two different missiles until after the fall of the Soviet Union.

Vladimir Nikolayevich Chelomey or Chelomei was a Soviet engineer and designer in the missile program of the former Soviet Union. He invented the first Soviet pulse jet engine and was responsible for developing the world's first anti-ship cruise missiles and the ICBM program of the Soviet Union such as the UR-100, UR-200, UR-500 and UR-700.
