How to bid on Lightweight Universal Codec (LUC) for DARPA

What DARPA is buying and why it matters

The Defense Advanced Research Projects Agency (DARPA) is seeking proposals for its Lightweight Universal Codec (LUC) program. This initiative aims to develop a universal encoder-decoder (codec) that can use any current or future communication error correction code. The goal is to create an adaptive error correction codec capable of making multiple, on-the-fly changes to these codes.

This research and development effort is important because it seeks to improve efficiency, security, throughput, and interoperability in communication systems. By developing a codec that can dynamically adapt its error correction methods, the Department of Defense aims to achieve record-setting low-power decoding and adaptive forward error correction, benefiting both military and commercial applications.

Key dates and what happens at the deadline

This Request for Proposals (RFP) was published on July 15, 2026. The deadline for submitting your proposal is August 28, 2026, at 1:00 PM ET. All proposals must be submitted by this exact time.

Missing the deadline means your proposal will not be considered. Ensure all required documents are complete and submitted well in advance to avoid any last-minute technical issues.

Who this opportunity suits

This opportunity is well-suited for small businesses with strong expertise in research and development, particularly in communication systems, error correction codes, and signal processing. Firms with a background in advanced algorithms, adaptive systems, and secure communications technology will find this relevant.

The program is executed at the unclassified level, with target implementations not exceeding Controlled Unclassified Information. Performers will select their own target communication systems for integration, demonstrating the greatest improvements through LUC implementation.

Practical tips for a competitive response

When preparing your response, clearly articulate your firm's technical approach to developing a universal and adaptive encoder-decoder. Highlight your understanding of the underlying principles, such as DARPA’s Guessing Random Additive Noise Decoding (GRAND) study, and how you plan to leverage or advance these concepts.

Provide a detailed plan for how your proposed codec will achieve multiple on-the-fly changes to error correction codes and integrate with existing communication technologies. Emphasize how your solution will demonstrate improved efficiency, security, throughput, and interoperability. Clearly identify the target communication system(s) you plan to use for integration and explain why these candidates will show the most impactful improvements.

Ensure your proposal addresses all evaluation criteria mentioned in the solicitation, such as code universality, link budget improvement, and performance in heterogeneous network environments. Present a realistic timeline and budget, and highlight your team's relevant experience and qualifications in this specialized field.
