The Common Autonomous Multi-Domain Launcher (CAML)-Lite Prototype Effort is a competitive procurement conducted under 10 U.S.C. section 4022 Other Transaction Authority to develop a mobile, optionally manned, autonomous launcher for cross-domain offensive and defensive fires. The program is structured in two phases, beginning with Phase 1, which requires a prototype demonstration at Talisman Sabre 2027 in August 2027. This initial phase includes a priced option for the acquisition of additional prototype units, New Equipment Training, and Contractor Logistics Support. Phase 2 focuses on prototype maturation and integration into a common CAML architecture. The government seeks solutions that utilize a Modular Open Systems Approach to ensure interchangeable modules and autonomous munition resupply with minimal human intervention. The procurement process begins with the submission of a Solutions Brief, with a deadline of October 26, 2026. The government will evaluate these briefs based on technical soundness, credibility in addressing objectives, and the feasibility of the maturation path to select the most meritorious respondents for a subsequent Request for Prototype Proposal. Award for Phase 1 is expected by December 18, 2026. Selected performers must assume full responsibility for international logistics and compliance for transporting systems to Australia. Funding for the demonstration will be provided at initial award, though performer investment is required and may positively influence selection. Final acceptance of the effort is contingent upon successful performance verification, cybersecurity Authority to Operate, and government approval of the Technical Data Package.

Protein Palace Proposers Day

Solicitation # DARPA-SN-27-01

The Defense Advanced Research Projects Agency (DARPA) is initiating the Protein Palace program to develop a universal, tunable protein purification platform. This initiative aims to replace the traditional lock-and-key paradigm with a system capable of purifying multiple proteins from a single system by leveraging unique physicochemical characteristics to improve specificity, generalizability, and scalability in biomanufacturing. The program is structured into two distinct phases: a 24-month Phase 1 focused on proving feasibility and specificity by separating eight different proteins, followed by an 18-month Phase 2 focused on increasing throughput and volume, demonstrated on two additional proteins that are difficult to purify using current state-of-the-art methods. To support this effort, DARPA is hosting an in-person Proposers Day on November 17, 2026, from 9:00 a.m. to 4:00 p.m. ET at the Executive Conference Center in Arlington, Virginia. Interested parties must register by November 9, 2026, and provide government-issued photo identification for entry. While the current Special Notice DARPA-SN-27-01 is for information and planning purposes and does not constitute a formal solicitation, DARPA anticipates releasing the full solicitation on sam.gov prior to the event. The Proposers Day will be held at the unclassified level, and any presented materials must be suitable for unlimited public release.

Cattle Run Proposers Day Announcement

Solicitation # DARPA-SN-27-03

The Defense Advanced Research Projects Agency (DARPA) is hosting a Proposers Day for the Cattle Run program on November 10, 2026, at the DARPA Conference Center in Arlington, Virginia. This event serves as an informational forum to discuss the program, address questions from potential proposers, and facilitate teaming opportunities. While this event is identified under solicitation number DARPA-SN-27-03, it does not constitute a formal solicitation for proposals or abstracts. The primary technical point of contact for the program is Mr. Steven Chambers, STO Program Manager. The Cattle Run program focuses on enabling cost-effective cislunar constellations by developing autonomous spacecraft that utilize solar sails or other renewable propulsion for long-duration maneuverability and station keeping. The project is phased to begin with the rapid development and launch of a demonstrator spacecraft below geosynchronous earth orbit to validate autonomous Guidance, Navigation, and Control (GNC) and acceleration capabilities, followed by the launch of multiple spacecraft for cislunar operations. Strict security and eligibility requirements are in place for all attendees. Participation is limited to U.S. citizens, and foreign nationals are not permitted. Because the event is conducted at the Controlled Unclassified Information (CUI) level, attendees must provide government-issued photo identification and a CMMC Unique Identifier during registration. Furthermore, the government requires verification of CMMC Level 2 compliance, which includes the 110 security requirements of NIST SP 800-171 Rev 2 and a current annual CMMC affirmation posted in the Supplier Performance Risk System (SPRS).
