## Summary

This activity requests $22.4M in FY2027, 57% of project 1950, down 1.3% 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.** -Continue design and component selection for the TI-28 S/CC/A configuration. -Complete land based integration testing at the System of Systems level for the emerging new architecture employing a common computing environment and Platform As A Service (PaaS) architecture. -Continue NPES level test and evaluation of cyber hardening measures in a land based test environment. -Generate GFI required for delivery to by the shipbuilder for any TI-28 configuration power, weight, cooling or and cabling changes.

**FY2026 to FY2027 change.** Decrease from FY26 to FY27 properly scales non-recurring engineering developmental scope of work planned in FY27.

## Before the request year

**FY2026 plans — current year.** -Initiate design and component selection for the TI-28 S/CC/A configuration. -Continue land based integration testing at the System of Systems level for the emerging new architecture employing a common computing environment and Platform As A Service (PaaS) architecture. -Conduct NPES level test and evaluation of cyber hardening measures in a land based test environment. -Update GFI required for delivery to the shipbuilder for any power, weight, cooling or cabling changes required by the shipbuilder to evaluate emerging new NPES architectures.
