About this file

This is an attachment to a Department of Defense contract solicitation that designates mission-essential contractor services subject to DFARS requirements for service continuity. The document, dated January 28, 2026, and signed by Contracting Officer Shaun Bright, identifies all services required within the Performance Work Statement (PWS) as mission-essential functions that must continue uninterrupted to support vital defense operations.

Offerors are required to submit a written plan with their proposals describing how they will continue performing the identified essential contractor services. The document defines essential contractor services as those provided under contract to DoD that support mission-essential functions, including support for vital systems such as ships operated in military missions, installation and garrison support services, and foreign military sales customer support under the Security Assistance Program. Services qualify as essential if their interruption would seriously impair the effectiveness of defense systems or operations. Mission-essential functions are organizational activities that must be performed under all circumstances to achieve DoD component missions; failure to sustain these functions would significantly affect DoD's ability to provide vital services or exercise authority, direction, and control.

Attachment 4 – Mission Essential Contractor Services

Date: 28 January 2026

Subject: Mission-Essential Contractor Services

In accordance with Defense Federal Acquisition Regulation Supplement (DFARS) 252.237- 7023, Continuation of Essential Contractor Services, the Government has identified the services to be performed under this contract as essential contractor services in support of mission essential functions.

In accordance with DFARS 252.237-7024, the offeror shall provide with its offer a written plan describing how it will continue to perform the essential contractor services listed in this document.

All services required within the PWS are deemed mission essential functions.

“Essential contractor service” means a service provided by a firm or individual under contract to DoD to support mission-essential functions, such as support of vital systems, including ships owned, leased, or operated in support of military missions or roles at sea; associated support activities, including installation, garrison, and base support services; and similar services provided to foreign military sales customers under the Security Assistance Program. Services are essential if the effectiveness of defense systems or operations has the potential to be seriously impaired by the interruption of these services, as determined by the appropriate functional commander or civilian equivalent.

“Mission-essential functions” means those organizational activities that must be performed under all circumstances to achieve DoD component missions or responsibilities, as determined by the appropriate functional commander or civilian equivalent. Failure to perform or sustain these functions would significantly affect DoD’s ability to provide vital services or exercise authority, direction, and control.
