The purpose of this Sources Sought announcement is to identify interested sources for Shaped Demolition Charges. This announcement is in support of Market Research performed by the United States Army Contracting Command - Rock Island, to determine interest in a planned Fiscal Year (FY) 2025 procurement for the 15 lb and 40 lb Shaped Charges. The U.S. Government (USG) anticipates a total contract length of 5 years. Item Description: Shaped Demolition Charge's primary use is for boring holes in earth, metal, masonry, concrete, and paved and unpaved roads. When the charge is detonated, the explosive is converted to a compressed gas. The gas exerts pressure in the form of a shockwave. The main charge converts the shaped liner into a high speed jet charge, which penetrates the target. The M2A4, 15 lb Shaped Charge penetrates reinforced concrete to a depth of about 3 feet, with the diameter of a hole tapering from about 2.75 in at the mouth. The M3A1, 40 lb Shaped Charge penetrates reinforced concrete to a depth of about 5 feet, with the diameter of a hole tapering from 3.5 inches at the mouth. M2A4, 15 lb Shaped Demolition Charge (NSN: 1375-01-023-7994) The M2A1 consists of 10 lb minimum Composition B, which is loaded using a melt-pour process. It also contains a 48 gram Composition A-3 booster charge. The explosive charge is enclosed in a molded fiberglass container with a glass cone liner and a tin plated steel closing cap. The shaped charge assembly also has a carrying strap made of cotton webbing and a detachable molded fiberglass 6 inches standoff. Each charge with the standoff is packed in a fiberboard box with foam cushions. Then the fiberboard box is put in a barrier bag. 4 charges are packed in a wooden box per drawing 9281170. M3A1, 40 lb Shaped Demolition Charge (NSN: 1375-00-088-6691) The M3A1 consists of approximately 30.5 - 1.5 pounds of Composition B, which is loaded using a melt-pour process. It also contains a 48 gram Composition A-3 booster charge. The explosive charge is enclosed in a seam welded or drawn sheet steel container along with a formed 10 diameter steel conical shaped charge liner. The liner is assembled using a crimp in conjunction with an adhesive/sealant. Brackets for which to affix the cotton webbing carrying strap are spot welded to the container. A drawn brass detonator well is soldered to a tin-coated steel closing cap which is press fit into the container after loading. The shaped charge assembly includes a detachable welded three-legged steel stand. Finished assemblies are covered in a barrier material and packed in wooden boxes per drawing 7549165. The Composition B and A-3 will be provided as Government Furnished Material (GFM). The manufacture of these shape charges requires special skills and facilities. Melt pour loading of high explosives is a critical technology. Critical skills include laboratory personnel, explosive operators, quality assurance, environmental, and research and development. Critical facilities include temperature controlled cooling bays, melt pour systems, real time x-rays/x-ray technicians. X-rays are important to determine whether the melt-pour casting contains cracks, voids, porosity, or separation. Defects can cause malfunctioning of the charge. The Contractor will be required to successfully conduct First Article Acceptance and Lot Acceptance tests on these items. The shaped charges are procured to USG Technical Data Packages (TDP).
