DARPA's Commercial Solutions Opening (DCSO) for Commercial Strategy

Solicitation # HR001126RE007

The Defense Advanced Research Projects Agency (DARPA) is soliciting Commercial Solutions Proposals (CSPs) under solicitation HR001126RE007 to transition DARPA-funded research and development into practical military and civilian capabilities. A central component of this effort is the Embedded Entrepreneurship Initiative (EEI), which aims to pair technical performer teams with experienced business talent to accelerate commercialization, reduce business risk, and attract private investment. The program focuses on developing value propositions, conducting competitive and techno-economic analyses, and creating comprehensive commercialization and intellectual property strategies. Offerors may also propose an optional Minimum Viable Product (MVP) plan to demonstrate utility and market entry. The government may award either a fixed-price FAR-based procurement contract or an Other Transaction (OT) for Prototypes under 10 U.S.C. 4022. While there is no formal ceiling, DARPA highly encourages base proposals to be limited to 350,000 dollars or less to expedite the evaluation and award process. Proposals are evaluated based on their potential contribution to the DARPA mission, commercialization readiness, and price fairness, though they are not ranked against one another. Key requirements include the identification of a qualified Embedded Entrepreneur as the sole key personnel, registration in the System for Award Management (SAM), and maintenance of CMMC Level 1 certification. All proposals must be submitted in unclassified format to [email hidden] by April 30, 2027.

Air Force Installation and Mission Support Center (AFIMSC) STREAMLINING PROCUREMENT FOR EFFECTIVE EXECUTION & DELIVERY (SPEED) Commercial Solutions Opening (CSO)

Solicitation # FA800325SC001

The Air Force Installation and Mission Support Center (AFIMSC) has established the Streamlining Procurement for Effective Execution and Delivery (SPEED) Commercial Solutions Opening (CSO), solicitation number FA8003-25-S-C001. This open, blanket CSO operates from September 1, 2025, to August 31, 2030, and is designed to facilitate the competitive procurement of innovative commercial items, technologies, and services. The program utilizes a multi-spiral solicitation process involving Area of Interest (AoI) calls, where the government seeks innovative solutions to meet specific Air Force needs. A notable example is the AFCEC CE IT Portfolio Optimization initiative, which seeks IT solutions to improve portfolio rationalization, cybersecurity, and data governance for the Air Force Civil Engineer Center. The CSO is a full and open acquisition available to small businesses and non-traditional contractors. Awards may be made as fixed-price contracts under FAR Part 12 or via Other Transaction Authority (OTA), with the Contracting Officer reserving the right to negotiate terms and payment conditions. Evaluation is based on pass/fail gates regarding the technical approach, performance schedule, and price reasonableness.

AI Contract Overview

The Department of Defense’s Naval Observatory is seeking information from potential vendors regarding the modernization and modification of the Very Long Baseline Interferometry (VLBI) Correlator System. This solicitation, identified as a Request for Information (RFI) and not a request for proposals or quotes, is intended solely for planning purposes and does not obligate the government to any contract. The project aims to develop an advanced, software-based VLBI correlator system that leverages recent advancements in electronic data transmission and high-performance computing to process increased volumes of VLBI data in near real-time. Additionally, the correlator components must comply with updated Department of Navy and USNO cyber security requirements. The US Naval Observatory’s mission involves precise time determination and celestial positioning to support Earth orientation and reference frame maintenance, and this effort supports ongoing developments including VGOS and next-generation VLBA systems. Interested parties are invited to submit information by the stated deadline via email to the designated government contact. Responses should include capability statements, relevant experience, and company information, but no direct proposals are requested at this stage. The RFI emphasizes that the government will not pay for response costs, and participation now does not guarantee inclusion in any future solicitations.

Full Description

Description

1.1 The purpose of this contract is to obtain services for modernizing and modifying the Very Long Baseline Interferometry (VLBI) Correlator System

1.2 THIS IS A REQUEST FOR INFORMATION (RFI) ONLY. This RFI is issued solely for information and planning purposes – it does not constitute a Request for Quote (RFQ) or promise to issue an RFQ in the future. This request for information does not commit the Government to contract for any supply or service whatsoever. Further, the Navy is not at this time seeking proposals and will not accept unsolicited proposals. Respondees are advised that the U.S. Government will not pay for any information or administrative costs incurred in response to this RFI; all costs associated with responding to this RFI will be solely at the interested party’s expense. Not responding to this RFI does not preclude participation in any future RFQ, if any is issued.

2.00 SCOPE

2.0 The mission of the USNO is to determine time, both atomic and astronomical, to determine and predict the positions of celestial objects and Earth Orientation and to provide this data to the DoW. VLBI observations are used by USNO to determine and predict the variable orientation of the Earth in three-dimensional space as well as to maintain the positions of the extragalactic radio sources which form the basis for the quasi-inertial celestial reference frame, within which the Earth Orientation Parameters are determined.

The objectives of this procurement are, 1) implement a state-of-the-art software based VLBI capability to take advantage of advances in the electronic transmission of observational VLBI data over the Internet to enable near real-time operations; 2) develop a software based VLBI correlator capability to take advantage of advances in high-performance computing needed to process higher volumes of VLBI data from VGOS and next generation VLBA systems; and 3) procure and deliver components for this correlator consistent with new and updated DoN and USNO cyber requirements.

3.0 Responses

Request Responses by TBD, 1:00pm EST. The response shall be submitted via e-mail only to the Government Point of Contract (POC): Michael Stoutenger, Program Analyst, contact@example.gov Questions regarding this announcement shall be submitted in writing to the POC.
