Brig. Gen. Michael Lutton, NNSA’s Principal Assistant Deputy Administrator for Military Application, said: "These qualification flight tests demonstrate the B61-12 design meets system requirements and illustrate the continued progress of the B61-12 life extension program to meet national security requirements. “The achievement is also a testament to the dedication of our workforce and the enduring partnership between NNSA and the US Air Force.” The original B61 gravity bomb is the backbone of the Air Force’s nuclear arsenal, along with the intercontinental ballistic missiles deployed from either ground-based silos or submarines. The B61 nuclear gravity bomb, deployed from US Air Force and NATO bases, has been in service for almost 50 years of service, "making it the oldest and most versatile weapon in the enduring US stockpile".
