The Naval Surface Warfare Center Crane intends to award a five-year Indefinite Delivery Indefinite Quantity contract with an estimated ceiling of $5M for new manufacture of multiple serpentine assembly variations for the AN/SPS-48E. The requirement is sole source to Loughmiller Tool and Design of Loogootee, IN, because competition could cause substantial duplicated costs or unacceptable delays. All responsible sources may submit a capability statement or proposal for consideration, though the decision not to compete is solely within the government’s discretion. Solicitations and amendments will not be posted to SAM.gov and are available only from the identified point of contact; contractors must be registered in SAM.
