Previously used Command Data Buffer 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, individual missiles can be retargeted in matter of minutes.
REACT incorporates 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 interesting feature which reduces missile crews' workload.
