1 Airborne Nuclear Command and Control System
The US Strategic Command has got a plenty of airplanes to sustain reliable and redundante control of the nuclear triad (ICBM, SSBN and Bombers) in case of bolt out of blue attack in order to retaliate adversary.

5 Conclusion
- US Minuteman Airborne Command Control System supports reliable communications with NCA in all scenarios including bolt-out-of-blue attack.
- Evolving from 1980 PACCS to the present ANCCS, ICBM command control became more robust and less redandant due to the obsolete ERCS, Looking Glass and PACCS relay systems.
- The future GBSD being to replace old Minuteman forces would provide more command and control capabilities due to the versatile airborne communications.
