RR-129A/AL Chaff Countermeasures

The RR-129A/AL is a RF passive (chaff) countermeasure that provides aircraft survivability and protection against RF guided threats and tracking radars. It is intended as an improvement over the existing RR-129/AL chaff countermeasure substituting a degradable material for the E-type glass normally used on current chaff. The new chaff countermeasure will have the same dipole cuts as the original RR-129/AL, with frequency coverage between 2-18 Ghz. The RR-129/AL consists of a cylindrical cartridge approximately 1.4 inches in diameter and 5.8 inches in length. Planned product improvements will also eventually incorporate degradable plastic for the end cap and piston.
