To provide Jennifer White and senior leadership with a comprehensive, data‑driven assessment of Phase I outcomes, identify residual risks, and outline a clear, actionable plan for Phase II.

The 128 Missax moniker reflects the target 128‑sensor configuration, each capable of dual‑band (X/Ka) operation, on‑board AI inference, and plug‑and‑play integration with multiple platforms (UAV, USV, fixed‑wing). The platform aims to:

| Aspect | Description | |--------|-------------| | Geographic Scope | Design & testing conducted at the corporate R&D campus (Silicon Valley) and the Navy Test Facility (San Diego). | | Temporal Scope | Q2 2024 – Q1 2025 (12 months). | | Functional Scope | Sensor‑array hardware, firmware, data‑fusion algorithms, and preliminary integration with the “Aquila” UAV platform. | | Methodology | • Design Review – System Architecture Boards (SAB) minutes.
• Laboratory Testing – 1,824 test runs covering RF, optical, and thermal performance.
• Simulation – Monte‑Carlo (10⁶ iterations) for reliability forecasting.
• Cost Tracking – Earned‑Value Management (EVM) with CPI = 0.97, SPI = 1.04.
• Stakeholder Interviews – 14 senior users (naval, aerospace, and commercial).
• Market Survey – 312 respondents across target segments. | | Data Sources | Internal test logs, SAP financials, Jira issue tracker, external market research (Frost & Sullivan, 2025). |

Overall recommendation: Approve Phase II with the outlined refinements and budget adjustments.

During high‑altitude (−20 °C) wind‑tunnel tests, sensor gain drifted by +0.42 dB beyond the acceptable envelope. A redesign of the aluminum‑ceramic heat‑sink (adding a thin‑film graphene interface) reduced drift to +0.07 dB, verified in repeat tests (see Appendix A‑2).
