The Defense Threat Reduction Agency intends to award a six-month sole source contract, with one six-month option, to General Dynamics Information Technology to prevent a lapse in critical nuclear logistics IT infrastructure support. This action is necessary while a follow-on procurement is actively competed, as no other source can assume operations without mission degradation. The contract will support the Defense Stockpile Management Systems (DSMS) for the entire U.S. Government. Interested parties must submit a capability statement within 15 days of this notice's publication to demonstrate their ability to assume full operations with minimal transition. No budget amount is specified, and the location for performance of services is not mentioned.
