## Summary

This activity requests $10.3M in FY2027, 100% of project 0486, down 24% on FY2026. The R-2A exhibit describes it across FY2026–FY2027, including what the FY2027 money is planned to buy.

## What the FY2027 request buys

**FY2027 planned work.** Installation of the CP-2 engineering development model (EDM) to meet fleet requirements to support Higher Than Secret (HTS) operations with expeditionary HTS shelters. EDM hardware includes: -Unclassified/Secret GENSER C4I hardware and software for burning and extracting P-8A Mission Systems and Combat Systems media, sensor data, and acoustic data - TS/SCI C4I hardware and software for burning and extracting P-8A Combat Systems media and sensor data - Network system hardware - Communication systems hardware - Hardened TS/SCI Shelter with Power and Heating, Ventilation and Air Conditioning (HVAC) to safeguard TS/SCI equipment CP-2 Test and Evaluation: - Developmental Testing focused on meeting CPD performance requirements and cybersecurity requirements - Integrated Testing and Operational Testing focused on meeting CPD performance requirements and utilization of the system in an operationally representative environment at NAS Whidbey Island with the TS/SCI ESS Shelter CP-2 cybersecurity: - Utilization of IATT for DT and IT - Full ATO authorization for IT and OT Improved processes: - Expand DSO to SIPRNet and transition to Orion - Expand Agile work to CP-2 and Block 2 FAK - Continue to develop MBSE model and incorporate DT/IT/OT results

**FY2026 to FY2027 change.** FY 2026 to FY 2027 reduction (-$3.238M) due to limited delivery of P-8A Increment 3 Block 2 ground station capabilities and delay of TacMobile CP-2 DT completion.

## Before the request year

**FY2026 plans — current year.** -Will conduct Software Integration Testing (SIT-3) and Development Testing (DT) for Capability Package 2 (CP-2) -Will develop software updates to maintain TacMobile alignment with P-8A software via PMA-290 P-8A Fleet Release (FR) annual mission software updates -Will continue transition of TacMobile into a DevSecOps environment -Will develop updates to the Preflight Insertion Data (PID) Validation tool for P-8A Inc 3 Block 2 aircraft -Will develop TacMobile Inc 3 CP-2 support for Fleet Advanced Airborne Sensor (AAS) capabilities for Legacy and P-8A Inc 3 Block 2 aircraft -Will develop a solution to support Fly Away Kit (FAK) transition which will result in Significant Size Weight and Power (SWaP) reduction in P-8 Aircraft Interface and Command and Control (C2) System and will allow transport via a single P-8 aircraft - P-8A FAK transition from TacMobile Flyaway Aircraft Support (TFAS) to TFAS Block 2 to support P-8A Inc3 Block 2 aircraft add Higher Than Secret enclave - Command and Control Systems transition to address SWaP - Configuration of non-terrestrial Automated Digital Network System (ADNS) backhaul infrastructure via COMSAT and direct TFAS Block 2 connection - Will incorporate and test ADNS backhaul infrastructure for ADNS-via-Starshield connection capability at Tactical Operations Centers (TOCs) and Mobile Tactical Operations Centers (MTOCs) enabling units to use Starlink/Starshield antennas.
