The United States Air Force's Rapid Execution and Combat Targeting System (REACT) is a modification of the LGM-30 Minuteman launch control centers (LCC's) that provides continual monitoring and rapid retargeting of Minuteman ICBMs.[1] It integrates communication systems and weapon systems into a single console.

There are now 4 launch keys that must be turned by the two missile combat crew members to initiate a launch vote. Prior to REACT, there were two keys.

The previous Minuteman III command and control system, designated Command Data Buffer or CDB, required over 20 hours to retarget the entire Minuteman force and 30 minutes to retarget a single ICBM. REACT system needs less than 10 hours to retarget all missiles, while individual missiles can be retargeted in matter of minutes.[2]

REACT was previously known as the ICBM integrated Electronics Upgrade (I2EU)

REACT incorporates a secure communication link between LCC and Higher Authority (SACCS) to receive and configuration and targeting data without any need for manual data input.

Automatic processing and decoding of Emergency War Orders is another feature which reduces missile crews' workload.

The REACT upgrades began around 1994. All Minuteman LCC's were upgraded.
