MJU-7/10 flare family

Also known as
  • MJU-7/10
  • MJU-7A/B
  • MJU-10/B
  • MJU-7
  • MJU-10

The MJU-7/10 flare family is a U.S. expendable infrared decoy line for aircraft self-protection, centered on the MJU-7A/B one-by-two-by-eight-inch flare and the larger MJU-10/B form factor. Chemring material places the family inside Kilgore's U.S. DoD conventional-flare portfolio and identifies compatibility with common ALE-series, M130, Vicon, and BOZ dispensers, while Textron lists MJU-7/10 flares among supported AT-6 Wolverine loads.

Family Designations

The record is a family page because public sources group the MJU-7A/B and MJU-10/B designations under the same conventional infrared countermeasure-flare line.

Dispenser Compatibility

Chemring material describes the family as aircraft-dispensed infrared expendables rather than stand-alone weapons. Public sources support broad dispenser compatibility for the family and a narrower AN/ALE-4X-series fit for MJU-7A/B.

It entered production in December 1996, pairs a launcher/controller installation with expendable decoy canisters, and is documented on F-16, F/A-18E/F Super Hornet, and B-1B aircraft as a compact radio-frequency self-protection system used from Kosovo and Iraq to later U.S. air operations.
