Low-Cost Multi-Function Ku-Band RF System for Prompt Strike Weapons

Department of DefenseUSAF

AI Overview

This RFP seeks development of an affordable multi-function Ku-band radar system for high-speed airborne platforms, addressing the current shortage of cost-effective options at scale. The system must integrate imaging radar, passive direction-finding, and fuze sensing within a compact 6-inch diameter configuration while meeting demanding thermal and performance specifications.

Official Description

Current multifunction radar systems for use onboard various types of small airborne platforms are prohibitively expensive to procure at scale, and this is especially true for systems engineered for use in demanding high subsonic regimes (peak velocity greater than Mach 3 but under Mach 5). This effort will leverage recent advancements in RF technology, high-temp materials science, and associated manufacturing to design a complete multi-function Ku-band RF system to a Critical Design Review (CDR)...

Informational change · Description

Low-Cost Multi-Function Ku-Band RF System for Prompt Strike Weapons

Q1 (subsonic vs. Mach 3–5 wording) went from unanswered to answered. No Q&As were added or removed.

  • Speed regime relaxed: The answer says "subsonic" was a mix-up, not a clean typo. The topic lead will accept a high-subsonic (Mach 0.7–0.8) multifunction RF system design. Supersonic (Mach 3–5) is no longer required.
  • Budget: The cost target remains the driver, at a $30–50K budget limit. Even a high-subsonic design strains that limit.
  • Evaluation: The subsonic platform variant is closer to production, which is why it is acceptable. Proposals that meet the high-speed environment within the cost limit will be viewed favorably, but this is a preference, not a requirement.

Why it matters: Applicants can now propose a lower-risk, lower-cost subsonic design without being non-compliant. Teams with supersonic-capable designs can use that as a differentiator only if they stay within the budget.

Low-Cost Multi-Function Ku-Band RF System for Prompt Strike Weapons

Added Q&A clarifying speed regime terminology. Q1 addresses a potential typo in the solicitation description, asking whether "subsonic" was a mistake and "supersonic" was intended given the Mach 3–5 range mentioned elsewhere.

Why it matters: This clarification is pending response but critical for applicants—it directly affects technical approach and feasibility assumptions. If the requirement truly covers subsonic speeds, the engineering scope and cost differ significantly from supersonic-only work. Applicants should await the official answer before finalizing proposals.
