Communications, Network, Engineering, Cybersecurity, and Information Technology Services (CNECTS), aka "Connects"

Solicitation # FA251827RCNECTS

The Communications, Network, Engineering, Cybersecurity, and Information Technology Services (CNECTS) acquisition is a high-priority effort by the Space Acquisition and Integration Office (SAIO) to consolidate multiple legacy IT support contracts into a single unified framework. Supporting the 21st Communications Squadron, the contract provides critical services across Peterson Space Force Base, Schriever Space Force Base, and Cheyenne Mountain Space Force Station. The scope focuses on mission systems, technical control, and the standardization of network infrastructure via AFNET, with a specific emphasis on modernization through data-driven automation, Zero Trust Architecture, and secure DevOps. This effort is structured as a 100% small business set-aside under NAICS 517810, with an estimated value of approximately 330 million dollars. The procurement utilizes a phased Commercial Solutions Opening (CSO) process rather than traditional FAR 15 procedures, consisting of a white paper submission, optional pitch sessions, and a final technical and price proposal. Evaluation is based on technical merit, importance to agency programs, and overall price and value, with a preference for a hybrid contract structure including firm-fixed-price and incentive-fee CLINs. The anticipated timeline includes a contract award on March 31, 2027, followed by a 60-day phase-in period and a base period starting June 1, 2027, extending through five option years and a final six-month extension.

Unified Network and Navigation Operations (UNNO) Request for Information

Solicitation # SCAN-MSFC-0002

NASA Marshall Space Flight Center is soliciting information for the Unified Network and Navigation Operations (UNNO) contract under the Space Communications and Navigation (SCaN) program. The initiative aims to consolidate the Near Space Network (NSN) and Deep Space Network (DSN) into a single One Network operational construct to improve accountability, reduce transition risks, and modernize mission-critical capabilities. The scope of work includes the operations, maintenance, sustainment, integration, and continuous improvement of unified network management, CONUS-based DSN facilities such as the Goldstone Deep Space Communication Complex, and NSN services including Space Relay and Direct-to-Earth capabilities. Performance will span numerous global sites, including facilities in Maryland, New Mexico, Guam, Australia, and Antarctica. The procurement strategy has transitioned from a two-category model to a single-award Indefinite Delivery Indefinite Quantity (IDIQ) model to ensure a unified management baseline. NASA intends to utilize a hybrid pricing structure consisting of firm-fixed-price (FFP) for standard operations and maintenance, and cost-plus arrangements for emergency, non-baseline, and mission surge support. While this is currently in the market research phase with a notional proposal date of March 2027, NASA is requesting capability statements and industry feedback to refine the Statement of Objectives. Evaluation of future proposals is expected to weigh technical merit, cost efficiency, past performance, and small business subcontracting plans.
