Sources Sought: Call For Technology Independent Verification &Validation (IV&V) 27-1: Spectrum Proof OPEN CALL for TECHNOLOGY US Army V Corps, in partnership with the Defense Innovation Unit (DIU), is initiating an open call to find, vet, validate, and integrate new and emerging technologies in alignment with US Army Europe's (USAEUR) Eastern Flank Deterrence Initiative (EFDI). IV&V 27-1: Spectrum Proof provides relevant scenarios to Joint Command participants as they seek to establish an operationally relevant environment for new technologies and design cost-effective, repeatable experimentation events relevant to the future of warfare. This announcement is a sources sought for capabilities The Government is not liable for payment of any costs incurred in response to this sources sought and participation in the Spectrum Proof experimentation event and is under no obligation to act in any way on the information received or make any awards from this event. No costs incurred by interested companies/technologies in response to this announcement will be reimbursed. The information provided may be used by any federal agency in developing a future acquisition strategy, Performance Work Statement (PWS), Statement of Objectives (SOO) and/or Performance Based Specifications (PBSs). Interested parties are responsible for adequately marking proprietary or competition-sensitive information contained in their response. Submissions will be assessed by a peer panel that may include Department of War (DoW) and supporting industry and academic Subject Matter Experts (SMEs) who will determine the technical merit of submissions based on maturity and mission threat alignment. If a submission is deemed “awardable” it may be eligible for award of further research, prototyping, procurement for experimental purposes, and even production under 10 USC 4021, 10 USC 4022, 10 USC 3458, FAR/DFARS Part 35, and DFARS Subpart 212.70, and 10 USC 4023. PURPOSE: The Proof series IV&V events focus on finding, vetting, validating, and integrating new and emerging technologies in alignment with EFDI's technology priority areas. This experimentation event provides relevant scenarios for Joint Command participants as they seek to establish an operationally relevant environment for new technologies and to design cost-effective, repeatable experimentation events for the future of warfare. The intent of the Proof series IV&V events is to identify select technology and companies to invite to participate in a follow-on operational environment event in the EUCOM theater. BACKGROUND: DoW experimentation events are vital for advancing military capabilities and ensuring strategic readiness. These events enable the validation of emerging technologies and innovative concepts and enhance operational effectiveness and preparedness. The mission of the Defense Innovation OnRamp Hub: Kentucky's IV&V program is to provide the DoW with a structured, repeatable venue for rapidly integrating, testing, and …
