Following a report released in January this year expressing concerns about the KC-46 Pegasus tanker aircraft, the US Air Force is working with the Pentagon’s operational test and evaluation office to dissuade these issues while maintaining the aircraft will keep to its milestones and schedules. One issue raised was that the aircraft did not meet the required standards for electromagnetic pulse testing but this was because not all of the systems were online during the previous round of tests. The test showed that the tanker’s flight-critical and boom-refueling systems could withstand a 6-decibel electromagnetic pulse, but certain systems were uninstalled or deactivated before testing, according to the report.
