Nightwatch Aircraft:Air Force Moves Ahead to Replace Doomsday Planes

As of this writing,only one defence contractor,the privately held Sierra Nevada Corporation (SNC),remains in the running for an 8.3 billion dollar contract to replace the current fleet of four US Air Force E-4B Nightwatch aircraft,often called the Doomsday planes because of their ability to withstand the radiological and electromagnetic effects of a nuclear war or other catostrophic circumstances.The future fleet of Nightwatch aircraft is called the Survivable Airborne Operations Center (SAOC) project.These aircraft also serve as the personal aircraft of the Secretary of Defense and shadow the President of the United States when he travels in an AN-25 Air Force One plane.Boeing withdrew from consideration on the grounds of the expense to the contractor involved in fixed price contracts.Fixed price contracts require the contractor to absorb cost overruns themselves.Boeing is already in the hole for the NASA CST-100 Starliner spacecraft and the replacement of the AN-25 Air Force One planes,to the tune of 1.3 billion dollars.* The E-4B is considered part of the nuclear deterrence force,as it provides Command and Control of all nuclear forces,including low frequency communication with ballistic missile submarines.The main mission of the SAOC is to provide a robust and survivable platform for the President of the United States and other senior leaders,via the National Command Authority mechanism,to initiate nuclear strikes and assure Continuity of Government while directing other major military operations,or respond to significant contingencies such as large-scale natural disasters.* The E-4B must be a large,four-engine airliner derivative,so are expected to be unused or lightly used Boeing 747-8 jumbo jets.They must be powerful enough to fulfill the Take Charge and Move Out (TACAMO) function;the nuclear command role;communications and security;as well as the essential redundancies.For its part,SNC recently held a ribbon cutting for one of a planned four maintenance,repair and overhaul hangers with attached painting facilities at its new Dayton,Ohio complex.The exact requirements for the SAOC are classified.SNC does have specialties in data and communications modifications to existing aircraft.It can perform post-production modifications without access to sensitive proprietary data from the original manufacturers.SNC has already identified appropriate aircraft for the project through X-ray screening.A competitive contract award by the Air Force is expected in early 2024.*The fleet will consist of an initial 8-10 aircraft,although it could be expanded to reinstate the Cold War Operation Looking Glass role in light of the hypersonic weapons threat posed by Russia and China,with an estimated warning time of only fifteen minutes.In Looking Glass,one of the aircraft is aloft 24/7/365 under the command of a general officer.*The Nightwatch aircraft are considered Weapons Systems.SNC has provided the Air Force with an Airlift/Tanker Open Missions Systems kit (ATOMS) kit.It uses existing antennas and cables to provide line-of-sight and beyond data connections to networks such as Link 16,giving aircraft more situational awareness.Such connectivity for a mobile fleet is considered essential by the Air Force.
