In November 2014, the U.S. Air Force began development of a version of the GBU-31 JDAM intended to track and attack sources of electronic warfare jamming directed to disrupt the munitions' guidance.

The GBU-31 is a guided air-to-surface weapon autonomously navigates to the designated target coordinates. (U.S. Air Force photo by Staff Sgt. Brittain Crolley) JDAM is currently compatible with B-1B, B-2A, B-52H, AV-8B, F-15E, F/A-18C/D/E/F, F-16C/D and F-22 aircraft.

The Joint Direct Attack Munition (JDAM) GBU-31 is a tailkit under development to meet both USAF and Navy needs, with the Air Force as the lead service. The program will produce a weapon with high accuracy, all-weather, autonomous, conventional bombing capability.

The designation GBU-31/B was allocated early in the JDAM program to 2000 lb class JDAM bombs with guidance kits from McDonnell Douglas (now part of Boeing). Current production JDAMs with 2000 lb class warheads are designated in the GBU-31(V)/B series.
