Compass Call

The Compass Call program is a vital part of the Air Force's airborne electromagnetic attack capabilities, aimed at disrupting adversary communications and radar systems. The main goal is to transition mission capabilities from the older EC-130H airframe to the more advanced EA-37B platform. This transition involves acquiring aircraft, producing modification kits, and integrating these components into the new airframe. The EA-37B is based on a commercial derivative G550 aircraft, which will be modified to accommodate Compass Call's Prime Mission Equipment (PME) and antenna arrays.

A key objective of the program is to ensure that the updated platform maintains its operational effectiveness by upgrading PME from the EC-130H to the latest Baseline. This upgrade is essential due to the aging EC-130H fleet, which requires re-hosting to sustain this critical capability. The program also aims for rapid delivery of these capabilities by pursuing concurrent developmental and production activities. So far, ten commercial derivative aircraft have been acquired, with configurations varying based on their procurement timeline.

The current resources for the program include ten EA-37B aircraft, two Compass Call Mission Crew Simulators (CCMCS), and one Weapon System Trainer (WST). In FY2023, resources were allocated for aircraft procurement, covering costs related to aircraft purchase, modifications, training and simulation procurement, support equipment, and other program support expenses. This allocation reflects the need to adapt quickly to changing threat environments and operational demands.

For FY2025, no additional resources have been requested for further procurement or associated support activities. This decision suggests that the focus is on effectively utilizing existing resources while meeting Combatant Commander requirements through potential redirection of funds as necessary. The strategic approach aims to optimize delivery of warfighter capability in response to evolving needs without expanding procurement efforts in the immediate term.
