Space Environment Technologies and Science (SETS) Broad Agency Announcement (BAA) Call 004

The SETS BAA Call 004 seeks contractors to develop and transition advanced real‑time high‑frequency (HF) propagation and ionospheric modeling tools that support over‑the‑horizon radar and other DoD operational systems. The effort is divided into several focused tasks: (1) tactical decision‑aid software development, (2) creation and integration of ionospheric models (SORcer, SEIM.STRES, OASIS, RIPE), (3) enhanced HF propagation tool development and verification, (4) model verification, validation, and fault‑simulation techniques, and (5) integration and transition activities with partner agencies. Deliverables include software products, technical reports, quarterly status reports, and final scientific reports, all marked Distribution Statement D and submitted via encrypted channels. The contract will be a cost‑plus‑fixed‑fee (or comparable) award with a total anticipated funding of roughly $5.3 million over a 39‑month performance period, requiring a Secret clearance and strict compliance with DoD security, reporting, and travel reimbursement rules. • Develop and deliver real‑time HF propagation and ionospheric simulation software (AFCAP extensions, I&W tools). • Produce and integrate models such as SORcer, SEIM.STRES, OASIS, and RIPE into AFRL enterprise solutions. • Perform verification & validation, fault‑simulation, and transition activities with MASE and other stakeholders. • Submit quarterly status reports and a final technical report, adhering to DFARS data‑rights and CUI marking requirements. • Maintain Secret‑level security clearance, follow travel cost‑reimbursement policies, and meet all reporting deadlines.
