OPEN - Proliferated Low-Altitude Detection for C-sUAS

Department of DefenseUSAF

AI Overview

This DAF RFP seeks low-cost detection sensors for a perimeter network to identify low-altitude drones, including non-RF emitting "dark" drones, in cluttered environments for USAF and USSF base defense. The system must integrate multi-sensor data into unified tracks and support remote control via API integration with Air Force command systems.

Official Description

This DAF focused open topic seeks C-sUAS detect options for transition into the USAF and USSF, specifically supporting AFLCMC/ES and the JIATF 401 marketplace. This effort seeks low-cost detection and recognition sensors to be configured as a perimeter network for early warning of low-flying drones. The sensors must be able to operate in cluttered environments and recognize non-RF emitting "dark" drones (distinguishing drone vs. not a drone). It must integrate data from all sensors at a node int...

OPEN - Proliferated Low-Altitude Detection for C-sUAS

  • Q10 removed/truncated in the updated version's visible content: The previous version included Q10 (cost ceiling scope, target RCS assumptions, performance metrics) with no answer. The updated text ends at A9 ("The topic identifies a projected CMMC Level 2 (Self) requirement. It..."), so Q10 appears to have been dropped or cut off; the cost-ceiling and target-signature questions remain unanswered.
  • Q1 answered (previously open): The government states the quoted "field-ready, production-representative" language does not appear in the published topic and that prototype delivery, inspection, and disposition terms will be set in the award instrument. Applicants should not assume physical delivery is required, but should expect those terms at award.
  • Q2 answered: No signed customer memo from the Air Force or Space Force is required; letters of support are optional.
  • Q9 answered (previously open): No government-furnished cloud environment or permitted LLM tools are identified, so offerors should budget for LLM hosting costs in the Phase II proposal.

Why it matters: Q2 removes a potential proposal barrier, and Q9 means cloud/LLM costs are the applicant's responsibility. Q1 defers delivery terms to award, creating some uncertainty for cost planning. The apparent loss of Q10 leaves the $100K ceiling scope (per node vs. system, and whether installation is included) still unresolved, which matters for pricing.

OPEN - Proliferated Low-Altitude Detection for C-sUAS

  • Added two unanswered Q&As: whether the field-ready prototype must be physically delivered to the Government or may be demonstrated and retained by the performer, and whether applicants need a signed customer memo from the Air Force or Space Force. Applicants should not assume either delivery or customer-memo rules are settled by these entries.
  • The existing Q&As remain, renumbered from Q1–Q8 to Q3–Q10. Prior answers on the under-$100,000 production-system cost, Direct-to-Phase-II feasibility, prototype rights, and projected CMMC Level 2 remain unchanged.

Q1 now has an answer. Previously unanswered, Q1 clarifies the $100k cost ceiling:

  • Applies to the complete final system at full-rate production (not per sensor node)
  • Includes every fielded component needed to operate and meet requirements
  • Installation labor is excluded from the $100k cost
  • Offerors may define their own production-volume assumptions to justify meeting the cost target
  • Government does not provide furnished hardware, software, or network infrastructure

This directly addresses a key applicant concern about budget feasibility and what costs must be absorbed.

OPEN - Proliferated Low-Altitude Detection for C-sUAS

Changes to Q&A Section:

New Question Added:

  • Q1 (new): Clarifies CMMC Level 2 requirement and asks whether government will provide free cloud environment for LLM coding assistants or if contractors must budget for it.

Renumbering:

  • Previous Q1–Q5 renumbered to Q2–Q6 to accommodate new Q1.

No substantive answer updates: The remaining questions (Q2–Q6) retain identical wording to previous Q1–Q5, suggesting responses remain pending or unchanged.

Q&A UpdatedSep 16, 2026 at 3:01 PM

Major Changes to Q&A:

New Q&A Added (Q1-Q2): Five critical clarifications added covering cost ceiling scope (per node vs. system-wide), target RCS specifications, performance thresholds (Pd, FAR, accuracy, latency), identification definition scope, and spectrum constraints for RF sensors on Air Force bases. Also added Q2 on feasibility evidence (simulation vs. physical hardware) and Medusa C2 interface documentation availability.

Reorganization: Original questions renumbered as Q3-Q5 with no content changes to those items.

Key New Clarifications: Cost structure, performance metrics, identification requirements, and prototype validation pathway now formally addressed.
