About this file
This is an Item Description document for a military aircraft component generated by the PRPS (Parts Request Processing System) on May 14, 2026. The item is an aircraft cartridge (NSN 1377012551598ES) classified as a fire suppression ballistic device used across various 135 aircraft. The cartridge is manufactured by CAGE code 05167 and is referenced under document number 30903861, with a TCTO (Technical Directive) number 11A18-14-7.
The cartridge measures 1.5 inches in length, 0.875 inches in width and height, and weighs 0.0711 pounds. It comprises a steel metal body with an electrical connector on one end, a threaded mid-section, and an explosive charge (1.4S classification, .41 grain) on the opposite end. The device functions by receiving an electrical signal that fires the explosive charge, which produces gas pressure to rupture a diaphragm in a bottle and release fire extinguishing agent to suppress fires. The item is designated as criticality code F, with demilitarization code G and security code 7. The document indicates this is a life-support fire suppression system component requiring careful handling due to its explosive nature and electrical initiation mechanism. The initiator for this item description is Terry L. Lightner from AFLCMC/EBHJ, contactable at DSN 586-9087 or commercial 801-586-9087.
