A detonating cord has a core of highly brisant PBXN-8 explosive surrounded by an inner braided layer of polyamide yarn, a flexible sealing sleeve of silicone rubber coated with glue, and an outer braided layer of polyamide yarn adhered to the sealing sleeve. Booster cups may be crimped to opposite ends of detonating cord to place booster charges adjacent the core to assure more reliable detonation of associated ordnance. The method of manufacture of detonating cord calls for providing a core of explosive PBXN-8 slurry, weaving an inner braided layer of polyamide yarn on the core, squeezing moisture out of the core of explosive PBXN-8 slurry during the weaving of the inner braided layer, applying a flexible sleeve of silicone rubber on the inner braided layer, coating glue on the flexible sleeve, and weaving an outer braided layer of polyamide yarn on the glue. Optionally, squeezing the core of explosive PBXN-8 slurry between rollers may be desirable to further remove excess moisture. The detonating cord of this invention provides safe, reliable, and non-electric detonation of boostered or boosterless insensitive warheads or shaped charges distributed along a line. The detonating cord of this invention: (a) withstands severe dynamic loading, (b) survives extreme environmental and logistics conditions, survives landing over razor sharp wire obstacles like triple standard concertina, and (c) meets all US DOD IM requirements of MIL-STD-2105 and NAVSYSCOMINST 8010.5.
