Resilient Integrated Photonic Transport In Denied Environments (RIPTIDE)

• New Q1 added on the distributed Group 3 UAS formation (8–12 optical hops, 200–300 nmi). The Government answered that a full 8–12 hop physical formation is not expected for the Phase II flight demo; instead, a minimum of three physical airborne nodes is required, with full 200–300 nmi scale validated through flight-measured data and scaling analysis. This materially lowers the Phase II hardware and flight-test burden and should shape your demo plan and budget.
• Former Q1 (SWaP limits) renumbered to Q2; its answer is unchanged: target payload SWaP limits are in the Phase II SOO under Supporting Documents & Templates.
• Former Q2 (beam steering) renumbered to Q3; answer unchanged: any beam-steering technology is acceptable if it fits Group 2–3 form factors.
• Former Q3 (coherent vs. direct detection) renumbered to Q4; answer unchanged: direct detection is acceptable.
• Former Q4 (D2P2 eligibility on prior flight demo) renumbered to Q5; answer unchanged: a completed integrated payload need not be previously flight-demonstrated; a non-trivial inter-endpoint link plus feasibility analysis is sufficient for review.

Why it matters: the only substantive change is the new Q1 answer, which signals that a three-node physical demo with scaling analysis is acceptable, a key scoping decision for proposal feasibility and cost.

New Q&A added on payload constraints (Q1):

The government clarified that Phase II has specific SWaP (size, weight, power, thermal) target limits for the optical payload, detailed in the Phase II Statement of Objectives within Supporting Documents & Templates. Applicants must select a representative Group 3 UAS platform and design their payload to meet these published constraints during Phase I feasibility analysis—rather than defining their own envelope.

Previous Q&As renumbered: The three existing questions on beam-steering technology flexibility, detection methods, and prior flight-demonstration eligibility remain unchanged but are now Q2, Q3, and Q4 respectively.

Status changed from status: Pre-Release to status: Open.

Description information changed.

Summary:

Clarifies that prior integrated flight demonstration is NOT required for D2P2 eligibility; applicants can establish feasibility through demonstrated constituent technologies and analysis, provided they show a non-trivial communication link between endpoints.
