The NATO Communications and Information Agency (NCIA) intends to issue an Invitation for Bid (IFB) for the Provision of System Software Engineering Services and System Transition for Basic Modules for Advanced Rapid, Targeting and Effects Mission Information System (ARTEMIS). To bid on this project, potential U.S. prime contractors must 1) maintain a professionally active facility (office, factory, laboratory, etc.) within the United States, 2) hold a current Facility Security Clearance (FCL) at the level of SECRET or higher; 3) be pre–approved for participation in NATO Competitive Procurement (NCP), 4) be issued a Declaration of Eligibility (DOE) by the Department of Commerce (DOC), and 5) register with NCIA's eProcurement tool, Neo. Contractor personnel must hold Personnel Security Clearances at the level of SECRET or higher. The reference for the IFB is IFB–424333–ARTEMIS–ABM and all correspondence concerning the IFB should include this reference. ARTEMIS is the next generation Joint Targeting System which will enable NATO to enhance, expand and improve federated Target Material Production in order to respond to crisis using full spectrum of targeting capabilities. The current Joint Targeting System (JTS/FAST) remains a valid targeting tool but is based on obsolete technology and has limited interoperability. The contract aims to deliver two main work packages: System Software Engineering Services, which, through Agile methods, ensure compliance with NATO HMI guidelines, ISO Standards, and operational requirements, while building interfaces for interoperability and future integration, resulting in fully developed ARTEMIS Basic Modules (ABM); and System Transition, covering installation, migration, and support for ABM alongside existing systems, ensuring operational continuity and user onboarding. An evaluated option for Operations and Maintenance services is included for a minimum period of two years, covering software maintenance, system performance monitoring, and release management.
