The requirement is for 26 battery assemblies (NSN 7H-6140-014708756, TDP VER 004), delivered to Northrop Grumman Systems Corp in Charlottesville, VA. The Government does not own the data or rights needed to contract repair from additional sources and has determined that buying the data or reverse engineering the part is uneconomical.

The Government is not using FAR Part 12 commercial-item policies, but interested parties may identify commercial-item interest and capability to the contracting officer.
