This procurement is a Sole Source to HII Unmanned Systems Inc for for 10 Hydroid Transponders and Assembly The Naval Surface Warfare Center, Panama City Division, (NSWC PCD), Panama City, FL intends to award a firm-fixed price purchase order for HII Unmanned Systems, Mission Technologies Division brand products. Procurement is for SDV MK8 Hydroid Transponders, as follows: Line No.     Description                                                                    Part Number                    Quantity 1                  ASSY; Transponder; CSS-LV; Aluminum; ID2                161907-2                          10 EA 2                  Associated Freight Costs                                                FREIGHT                          1 EA The Naval Surface Warfare Center Panama City Division (NSWC PCD) has a requirement to procure SDV MK8 Hydroid Transponders.  This requirement is not suitable for full and open competition for the following reasons: This acquisition is conducted under the authority of FAR 12.102, Restricting Competition. The determination has been made that only one source is reasonably available to meet the Government's minimum needs. HII Unmanned Systems is the OEM and the only approved source of supply for the items listed above per the approved engineering drawing. The purchase of a different brand of transponder would necessitate approximately 6 months or more of work to ensure compatibility of the alternate transponder with the SDV system. Additionally, further work would be required to approve it for use with the SDV system. The additional time and expense generated by these efforts would result in unacceptable risk to the project timeline and additional cost to the Government. As such, the government does not expect significant savings through competition and it is more advantageous to the Government to award on a sole source basis to HII Unmanned Systems for the items listed above.
