The United States Space Force’s Operational Test and Training Infrastructure (OTTI) Commercial Solutions Opening (CSO), identified by solicitation number FA2553-25-S-C001, is an open-ended procurement vehicle designed to acquire innovative commercial technologies and solutions for space test, training, and infrastructure modernization under DFARS 212.70. The solicitation is structured around five distinct Areas of Interest (AOIs), each outlining specific technical challenges including Continuous Fitness Assessment (CFA), Multirole Satellite Frequency In-field Test Suite (MSFITS), Distributed Synthetic Training Environment Evolution & Prototyping, National Space Test and Training Complex (NSTTC) Range Control System Enhancements, and associated cybersecurity and data integration requirements. Proposals are evaluated through a phased process—Phase I involves a brief PowerPoint and white paper submission, Phase II includes a virtual pitch, and Phase III requires a full technical, SOW, and price proposal. The Phase I deadline for AOI 05 has been extended to December 5, 2025, and updates to AOI 04 and AOI 02 have been released via revised Q&A documents, clarifying software interfaces, deployment environments, system architecture, and access to subject matter experts. The solicitation emphasizes unclassified submissions for early phases, with classified work only possible in later stages if the offeror is equipped to handle it independently under a DD Form 254. Proposals are assessed based on equal weighting of technical merit, importance to DoD programs, and price, with awards made on a trade-off basis and subject to incremental funding availability. The Government retains discretion to fund any number of proposals, including partial funding, and all awarded contracts are issued through Other Transaction Authority frameworks, not traditional fixed-price or IDIQ vehicles. The place of performance is Peterson Space Force Base, Colorado Springs, CO, with submissions handled electronically through email to designated AOI Contracting Teams. Offerors are required to have active SAM.gov registration, a Unique Entity ID, a CAGE Code, and must comply with NIST SP 800-171, as verified through SPRS. Organizational conflicts of interest are strictly prohibited, particularly for firms currently supporting OTTI in A&AS, SETA, SE&I, or FFRDC roles, and foreign entities are ineligible due to MCTL restrictions. Large businesses must submit a small business subcontracting plan, and all proprietary information must be clearly marked. The CSO is designed for continuous operation
