Radar Bomb Scoring (RBS) is a combat operation used to evaluate Cold War aircrews' effectiveness with simulated unguided bomb drops near radar stations of the United States Navy, the USAF Strategic Air Command, and Army Project Nike units. USAF RBS used various ground radar, computers, and other electronic equipment such as jammers to disrupt operations of the bomber's radar navigator, AAA/SAM simulators to require countermeasures from the bomber, and Radar Bomb Scoring Centrals for estimating accuracy of simulated bombings. Scores for accuracy and electronic warfare effectiveness were transmitted from radar sites such as those at Strategic Training Range Complexes (e.g., from Detachment 1 at the "La Junta Bomb Plot").
