The Army Contracting Command, Redstone Arsenal – Letterkenny Army Depot is conducting market research to identify potential sources for Environmental Control Systems (ECS) (Part Number 13645428-1) and incidental installation services at Letterkenny Army Depot (LEAD) for the AN/TPY-2 Electronics Equipment Unit. The ECS must be produced according to MDA Drawing 13645428 (Distribution F), and the government lacks rights to the technical data package; only approved, pre-qualified sources are eligible, with SAM registration required. Interested businesses should provide a capabilities statement covering company data, NAICS 333415 business size and socioeconomic status, SAM registration, manufacturer vs. distributor role, capability documentation, teaming or subcontracting structure, and past performance. The government also requests firm-fixed pricing for a potential five-year contract vehicle and a Rough Order of Magnitude for approximately two ECSs per year plus installation. This is market research only, not an RFP, and responses are voluntary with no government obligation or cost reimbursement.
