According to TASS on January 23, researchers from the Khrushchev Material and Technical Support Military Academy in Russia have applied for a patent for a new ground nuclear explosion simulator. The patent specification held by TASS indicates that the use of this research and development achievement can enhance the quality of training conducted by the Army in response to the use of nuclear weapons. The article states: "The purpose of using a simulator is to visually simulate various visual signals - the attack effect of a ground nuclear explosion, the mushroom cloud formed by light and dust." This invention will be used in military training and practical exercises to improve the quality of training conducted by the army around the use of nuclear weapons, as well as to determine the parameters of nuclear explosions by radiation, chemical, and biological ground reconnaissance units Calibrate the horizontal position of the explosion center. Researchers say that the IU-59 nuclear explosion simulator used to be used, but it is outdated and companies no longer produce it. The inventory in military warehouses has already exhausted their technical resources and is absolutely prohibited from use. Another similar simulator mentioned in the article is the IAB-500, which simulates the combat effectiveness of RN-24, an aviation bomb carrying nuclear ammunition. The article points out that "the disadvantage of IAB-500 is that it is specifically developed for frontline aviation. Therefore, it is not cost-effective to use it for practical training of radiation, chemical, and biological ground reconnaissance units of various branches of the military, as the expenditure will far exceed the results achieved. In addition, IAB-500 was retired in 1984 and military factories no longer manufacture it."
