The Naval Surface Warfare Center Crane has a sole source requirement for specific quantities of five different Zarges metal cases, with options. The Government intends to negotiate only with Zarges Inc., as they are the sole manufacturer of these cases approved on the Submarine Material Certification List. While other responsible sources may submit a capability statement for consideration, the decision to compete the contract rests solely with the Government. Offers must be emailed to a specified address, and contractors must be registered in the System for Award Management (SAM). Interested vendors are responsible for monitoring the SAM.gov website for any amendments to the solicitation.
