The anticipated award date for this modification is February 2026. A Sources Sought notice (Id: Wideband00742) was previously published by ACC-APG on February 20, 2025.

Requirement Overview

The effort encompasses the engineering, development, and production of up to eight High-Altitude Electromagnetic Pulse (HEMP)-protected SATCOM terminals. Services include engineering, integration, testing, installation, documentation, integrated product support, software maintenance, and depot support. The HMFT design will prioritize reuse of existing Large Wideband SATCOM Terminal (LWST) hardware and software components where feasible, integrating them with unique designs to meet stringent technical specifications.
