The Department of Defense, specifically the Department of the Army, is seeking to award a contract modification to Pearson Engineering LTD (PEL) for Contractor Spare Parts (CSP) related to Engineering Breaching Systems (EBS) for the M1074, M1150, and M88A2 weapon systems. This procurement involves a total of 749 individual line items, with 31 high-value items identified, including critical components such as manifold assemblies and various harnesses necessary for the operation of these systems. PEL is the sole manufacturer of the EBS and possesses proprietary knowledge essential for the continued production of these spare parts, which limits the availability of competitive acquisition data. Interested parties are invited to submit capability statements to Leonard J. Miller at leonard.j.miller49.civ@army.mil, noting that this is a sources sought notice and not a request for proposals.
