Edited sentence: Scientists debated the efficacy of the binary weapons program, especially since the BIGEYE had only been tested using simulants, despite the fact that extensive and highly representative kinetic and kinematic simulant tests were performed.The GAO repeatedly backed these assertions without engineering substantiation, maintaining that the BIGEYE was not adequately tested and that it had encountered major technical issues.This again confirmed GAO's lack of scientific/engineering understanding of the weapon concept/deployment strategy.Unfortunately, GAO's less than informed report led to speculation that binary weapons might be inferior to those of the unitary weapons they were intended to replace despite their inherent safety for US military personnel.While the program did encounter major technical issues, the Navy with its USAF and USA partners successfully resolved all of the legitimate engineering issues and developed highly effective mission profiles for the weapon
