The Department of Defense, through the Defense Threat Reduction Agency (DTRA), is seeking to increase the ceiling on the Cooperative Threat Reduction Integrating Contract (CTRIC) III by $164.4 million, raising the total from $970 million to $1.13 billion. This increase is justified under 10 U.S.C. 3204(a)(1) and FAR 6.302-1(a)(2)(iii)(B) due to the urgent need to maintain mission-critical services related to the elimination, mitigation, transportation, and security of weapons of mass destruction, particularly in light of unforeseen demands such as those arising from the Ukraine conflict. The ceiling increase is essential to bridge the gap until the successor contract (CTRIC IV) can be awarded around July 2024, as market research indicates that only a limited number of contractors possess the required expertise.
