Common Autonomous Multi-Domain Launcher (CAML)-Lite Prototype Effort

Solicitation # W50RAJ27CAML_LITE

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.

AI Contract Overview

The U.S. Environmental Protection Agency's National Homeland Security Research Center is seeking a contractor to develop predictive models that estimate the acute and sub-acute toxicity of various chemicals. These models will be based on experimental toxicity benchmark data such as LD50, LOAEL, BMD, or BMDL10, and will employ Quantitative Structure-Toxicity Relationships (QSTRs) for both oral and inhalation exposure routes. The contractor is required to create distinct QSTR models for each benchmark and route of exposure. The contract, titled "Development of Statistically Based Quantitative Structure-Toxicity Relationship (QSTR) Models for Predicting Acute and Sub-Acute Toxicity Benchmarks for a Variety of Chemicals," was posted as a presolicitation in July 2005 by the Environmental Protection Agency's Cincinnati Acquisition Division. The work emphasizes the use of statistically driven modeling approaches to improve toxicity prediction, supporting the EPA's mission to assess chemical hazards effectively. The place of performance is unspecified, and the contract does not indicate any set-aside provisions.
