Description (excerpt)
B-52 Data Interface Unit/Data Transfer Receptacle (DTR) The Government is conducting market research to identify potential sources with the expertise, capabilities, experience, facilities, and technical capacity necessary to manufacture/provide and repair the B-52 Data Interface Unit/Data Transfer Receptacle (DTR). The National Stock Number (NSN) and Part Number (PN) are as follows: LRU: NSN 7025-01-738-4504AY, P/N P210015K0001-1, INTERFACE UNIT, DATA This Request for Information (RFI) supports a buy and repair requirement for the new Form, Fit, Function, and Interface (F3I) DTR. Kihomac, Inc. is currently manufacturing the F3I DTR under contract SPRWA1-21-D-0015. The Government owns, or will provide under appropriate controls, the manufacturing and technical data necessary to support competitive production and repair of this item.

The DTR transfers Offensive Avionics System (OAS) information to and from storage on the Data Transfer Cartridge (DTC) across its interface with the Fibre Channel or MIL-STD-1553A data bus system. Additionally, the DTR provides status over the MIL-STD-1553A and Fibre Channel buses indicating that the DTC is successfully installed. The required scope shall include, as applicable, manufacture and delivery of new production DTR units; hardware repair and return of unserviceable DTR units; obsolete parts resolution; engineering support to investigate Deficiency Reports (DRs); Diminishing Manufacturing Sources and Material Shortages (DMSMS) support; development, maintenance, and execution of required inspection, test, and acceptance procedures; and configuration management support to ensure newly manufactured and repaired units conform to the applicable Government-furnished technical data package. All newly manufactured and repaired units must meet applicable form, fit, function, and interface requirements. The contra …
