LUU-2 Flares



The LUU-2D/B flare is the latest in a series of illuminating flares introduced by ATK Aerospace Group for nighttime target illumination and rescue missions. Designed as a multi-service flare by the U.S. military, the LUU-2D/B incorporates improvements and modifications that further enhance its performance and reliability. The LUU-2D/B has been selected by over 30 countries for aircraft-deployed illumination.

Delivery Systems

The LUU-2D/B flare is compatible with all standard flare launching systems used on rotary- and fixed-wing aircraft. It can be deployed from LAU-74 cargo aircraft launchers, aircraft wing-mounted racks, and the SUU025, -42 and -44 series launchers. It can also be hand-launched from aircraft.

Operational Sequence

  1. Mechanical timer controls freefall drop-time prior to parachute deployment
  2. Release mechanism ejects the timer assembly, which deploys the attached parachute
  3. The load applied to the ignition lanyard by deployment of the parachute activates the ignition system, which ignites the flare candle
  4. The illuminant grain and aluminum case are consumed at the same rate
  5. As the candle burns out, an explosive bolt is initiated, severing one of the parachute attachment cables
