In October 2003 the U.S. Army Aviation and Missile Command (AMCOM) sought sources for loading thermobaric explosive fills into TOW Bunker Buster warhead cases. Ingredients for these thermobaric formulations may include nitramine based oxidative materials such as HMX and RDX, nitrate ester plasticizers such as BTTN and TMETN, energetic polymers such as GAP, inert polymers such as HTPB and PEG, and metal powders such as aluminum, titanium, and magnesium. Warhead case design is fixed and will require casting tooling for proper finishing of the fill. Depending on the exact density of the specified thermobaric fill, each warhead will contain approximately seven (7) pounds of explosive. One hundred (100) cases are anticipated to be supplied to the source for loading. To adequately process and load the formulations, the source shall have vertical mix and slurry-cast facilities. The source shall therefore supply information relative to their processing capability. The anticipated program will require the source to load tw o (2) different thermobaric fills. One will be specified by the U.S. Army and the other will be proposed by the source. The source chosen fill shall be limited to either a qualified explosive or an explosive that is in the process of being qualified. Su fficient data shall be supplied by the source to verify the validity of the alternate explosive fill according to known criteria for thermobaric formulations. These criteria will include, but are not limited to, blast overpressure, heat flux, and temperat ure. The castable explosive specified by the Army will be an isocyanate cured, polymeric formulation.
The source proposed alternate formulation is not limited to the cast, cured type.
