Strategic Automated Command and Control System

)[citation needed] The Strategic Air Command Digital Information Network was deployed to replace SACCS' "Data Transmission Subsystem and part of the Data Display Subsystem",[1] e.g., on November 5, 1986, "Martin Marietta Corporation technicians began installing SAC Digital Network (SACDIN) equipment in 91st Strategic Missile Wing missile launch control centers[2] (i.e., either a HUTE rack or MBCP rack).

"[2] SACDIN eventually "linked 135 locations and permitted two-way message communications with ICBM launch control centers for the first time,"[2] and the Ground Wave Emergency Network communication system had a Final Environmental Impact Statement issued in September 1987.

[6] The USSTRATCOM SACCS was later redesignated Strategic Automated Command and Control System with the same acronym.

"[3] By 2011, the Minimum Essential Emergency Communications Network was being modernized in the Nuclear Command and Control System.

[7] By February 2012, USSTRATCOM was using the Integrated Strategic Planning and Analysis Network (ISPAN), and the USSTRATCOM Replacement Facility Fit-Out (PE 0303255F) was to "include secure HEMP-Shielded Command and Control Center, mainframe computer data centers, multiple 24/7 mission operations centers, storage and maintenance areas, labs/workrooms, back-up generators, Uninterruptible Power Source, Technical Control Facility, Fiber Ring, [with funding] beginning in FY13.
