Over the years that the Air Force had operational E-4 aircraft, little has been puplished about the aircraft and few people, even Air Force personnel, were aware of the aircraft or the mission. The primary body of the E-4 was that of a 747 airceaft. Prior to being assigned to Offutt AFB NE the E-4 aircraft were assigned to Andrews AFB. At that time I was the Tech Advisor for the DCM at Offutt AFB. A team of Air Force personnel from Offutt AFB were sent to Andrews to conduct an ORI on the E-4 Operation. As the senior CMS (E9) with the group I was the enlisted team chief for the ORI Team. After the ORI was completed, several of the ORI Team members were flown back to Offutt on one of the E-4 Aircraft. I was very impressed with what I was allowed to see on the flght. Soon after we returned to Offutt AFB, we were informed that the E-4 operation was going to be moved to Offutt AFB. The primary mission for the E-4 at that time was as an Airborn Command Post in case of war. The secondary mission was the survival of the President of the USA and as such, one of the aircraft was flown to Andrews AFB when ever the President was in DC and when he left DC, one of the aircraft had to be flown to a location within 15 minutes of where the President went. The Air Force refered to these mission as AABNCP and NEACP Missions.
At the time the E-4 Aircrft was moved to Offutt AFB, the Air Force had only four of the specially build 747 aircraft, which the Air Force called the E-4 Aircraft. To perform the assigned missions, the aircraft require a large number of very expensive black boxes. Even with the importance of the missions, only enough money was approved to purchase three sets of black boxes. Therefore, a utilization schedule had to be drafted to move black boxes from aircraft to aircraft when an aircraft needed to be taken out of service for maintenance. I was personally request by Hq Sac to perform this task. 07/18/2008 @ 13:12 [ref: 22171] |
Marty Boone Puyallup, WA | I was a Crew Chief/Flight Mechanic on NEACP from 1983-1990. Best years of my 21 year USAF career. Jim Goldsmith, nice to see your comments. I remember working with you at Grissom when I was on alert there. My wife Cindy was a Battlestaff member from 1987 to 1990. She was assigned to Team 1. We both have many, many fond memories of our fellow crew members. Being assigned to NEACP influenced my career in aviation. I'm still in the aviation business as an Aviation Safety Inspector with the Federal Aviation Administration up in the Seattle area. If any one knows of other E-4B, Nightwatch, NEACP or NAOC websites or blogs please let me know. This site has brought back some wonderful memories... 06/14/2008 @ 22:18 [ref: 21427] |

CMSgt Mike Sternberg Perry, GA | I was assigned to the NEACP as a OJCS communications specialist from Jan 67 through May 75. During that period, I was on the acquisition team for the E-4A. Spent a lot of time at Greenville, TX until the E-4As (three of them) were delivered to Andrews AFB beginning in late 1974. Transferred to the 1ACCS in May 75 as the first superintendent of communications operations. Held that position until Sep 77. Was then sent to the Air Force Test and Evaluation Center at Kirtland AFB and assigned to the acquisition support and test crew for the E-4B which was being built by Boeing in Seattle. Spent most of a year TDY to Seattle and other places where black box systems were being developed for the aircraft. Retired in Aug 78 after completing initial flight tests out of Renten and Moses Lake. Beautiful aircraft. Am very proud to have been part of its history. Worked in Virginia for several years after retiring from the Air Force and would sometimes see the aircraft fly over while landing or taking off from Andrews AFB. Always wished I could be back on it. 07/31/2007 @ 13:21 [ref: 17387] |

Than we moved to Grissom in the summer of 83. I had a big part in setting up the Grissom alert center and the parking area for the airplane. I retired in July 1987 almost 20 years ago. 02/15/2007 @ 17:17 [ref: 15538] |
