This is a post-award notice of a Justification for Exception to Fair Opportunity for a sole-source task order awarded by the Naval Undersea Warfare Center Division Newport. The task order covers highly specialized engineering, technical, and programmatic support services. The sole-source award was justified because only the awardee possesses the required proprietary technical data and engineering expertise, and using another contractor would cause unacceptable operational delays and substantial, non-recoverable duplication costs. A redacted Justification for Exception to Fair Opportunity document is attached in accordance with public posting requirements.
