Relentless Wolfpack CALL Amendment

The Air Force Research Laboratory, Air Warfare Directorate is soliciting technical and cost proposals under the PACER Broad Agency Announcement for Relentless Wolfpack CALL 01_RA South, an Other Transaction for Prototype agreement, with proposals due October 2, 2026 and clarifying questions due September 2, 2026. The Government anticipates awarding 2–8 OTs, reserving the right to award zero, one, or more based on performer capability and funding availability.

The 20-month effort (18 months performance plus 2 months final reporting) focuses on demonstrating multiple weapons from different vendors working together to synergize effects and neutralize targets in contested battlespace environments, with emphasis on Research Area 9 Autonomy. NAICS 541715 applies, with a small business size standard of 1,500 employees. Place of performance and administrative oversight are at AFRL/RA, Eglin Air Force Base.

Performers must be actively registered in SAM.gov, maintain Level 1 Cybersecurity Maturity Model Certification, and provide a certified DD Form 2345 by August 26, 2026 at 12:00 PM CT to receive the call package. Critical requirements include electronic submission via PIEE Solicitation Module (primary) or DoD SAFE (secondary); technical proposals limited to 25 pages plus a 22-page Statement of Work (double-spaced, 10-point Arial, 1-inch margins); and cost proposals with Technical Basis of Estimate, milestone payment schedule with acceptance criteria, unburdened labor and skill mix matrix, and summary of major materials and subcontracts. Government will provide radios as Government Furnished Property with rental value added to performer cost for evaluation. Associate Contractor Agreements between prime performers are required; exceptions are prohibited.

The Government proposes Fixed Price milestone-based payments tied to observable, measurable technical deliverables. Evaluation ranks Technical Merit (innovation, understanding of scope, soundness of approach, transition potential—equally weighted) as most important, followed by Cost/Price Realism. Incremental funding supports work in FY27 and FY28. Anticipated award date is December 10, 2026. No white papers will be reviewed during the moratorium period from publication through one month after the proposal due date. Amendment 1 (posted September 14, 2026) revises the Statement of Objectives, ADRLs, and Milestone Payments; performers who received the initial call must request revised documents.
