Airmen gear up for largest B-1 modification: Sustainment-Block 16, or SB-16, includes significant upgrades to the B-1, including the Fully Integrated Data Link and Central Integrated Test System in the aft station and the Vertical Situation Display Upgrade in the front station. Included under the umbrella of SB-16, the B-1 will also receive navigation, radar and diagnostic upgrades.
The VSDU upgrades the B-1's forward cockpit by replacing two unsupportable, monochrome pilot and co-pilot displays with four multifunctional color displays, giving the pilots more situational awareness data in a user-friendly format.
The B-1 FIDL will give the aft cockpit new digital avionics including a Link 16 data link that adds line-of-sight capability to the B-1's existing beyond line-of-sight Joint Range Extension Applications Protocol data link and integrates the JREAP, data onto new, full-color displays with intuitive symbols and moving maps.
The CITS upgrade adds a new color display in the aft cockpit and replaces an obsolete computer that continuously monitors the aircraft's performance. It is used by flight and ground support personnel to identify and troubleshoot B-1 system anomalies.
These three modifications fall under the Integrated Battle Station initiative, which is slated to be installed concurrently through 2019.
