How to bid on RF Architectures Applying Photonic Timing and Routing (RAAPTR) for DARPA

What DARPA is buying and why it matters

The Defense Advanced Research Projects Agency (DARPA) is looking for research proposals for new radio frequency (RF) system architectures. These systems must use precise optical timing and be suitable for compact mobile land, air, and space-based defense platforms.

DARPA is seeking innovative, non-evolutionary approaches to create vibration-hardened components and subsystems. This includes ultra-low phase noise photonic oscillators and high-performance analog and digital subsystem architectures. This opportunity is for firms that can develop revolutionary advances in these areas, not just incremental improvements to existing technology.

Key dates and what happens at the deadline

This solicitation was published on July 10, 2026. The deadline for submitting proposals is August 24, 2026, at 1:00 PM ET.

It is critical to note that you must request a separate Controlled Unclassified Information (CUI) addendum for more detailed program information. This request must also be made by the stated deadline. Failure to request the CUI addendum by the deadline will likely impact your ability to submit a complete and competitive proposal.

Who this opportunity suits

This opportunity is best suited for research-focused firms with expertise in advanced RF systems, photonics, optical timing, and vibration-hardened components. It targets entities capable of developing revolutionary, rather than evolutionary, technological advancements.

The work falls under the professional services category, specifically for advanced research and development in defense technology. Firms with a strong background in physics, electrical engineering, and materials science related to these fields would be well-positioned.

You may need to create a free account on the portal to view all documents. Be sure to follow the instructions in Attachment A of the Program Solicitation to request the Controlled Unclassified Information (CUI) addendum by the August 24, 2026 deadline. This addendum contains crucial details for your proposal.

Practical tips for a competitive response

Given DARPA's focus on innovative and revolutionary approaches, clearly articulate how your proposed solution goes beyond current state-of-the-art technology. Emphasize the unique aspects of your photonic timing and routing architectures.

Pay close attention to the requirement for vibration-hardened components and subsystems. Provide specific details on how your proposed designs will achieve the necessary ruggedness for mobile defense platforms. Ensure your proposal directly addresses the defense-relevant use cases and mission capabilities mentioned.

Since a CUI addendum is required, make sure to request it well in advance of the deadline. This addendum will provide essential context and specific requirements that will be vital for crafting a compliant and competitive proposal. Do not assume you can submit a strong proposal without reviewing the CUI details.
