Mode 5/S

Abstract

B-1B Identification Friend or Foe (IFF) Mode 5/S is the replacement for the B-1B Mark XII IFF Mode 4. Mode 5, which will replace Mode 4, will provide secure target identification and will be a response system for combat identification. Mode Select (Mode S), which will replace Mode C, provides timely aircraft position and flight path prediction to receiver units for aircraft, Air Traffic Control, and the Air Defense System. The IFF Mode 5 upgrade uses an automated system that responds to interrogations to avoid the loss of B-1B aircraft through fratricide. Mode 5 is a Joint Requirements Oversight Council (JROC) 2020 mandate. Mode S is required in International Civil Aviation Organization (ICAO) airspace. Failure to meet these mandates will result in delayed/denied service of controlled airspace within the US and Europe. Program was de-scoped to remove ADS-B requirement based on several factors including Operations and Emission security (OPSEC/EMSEC) concerns.
