1 SCOPE

This Systems Requirement Document (SRD) describes attributes, performance parameters, processes, objectives and other requirements needed for a C/KC-135 satellite communication (SATCOM) replacement. The SATCOM replacement is needed to replace a third generation Inmarsat Aero-I

SATCOM service which will be discontinued in FY 22.

1.1 System Identification

The current Inmarsat communications system was installed as part of the C/KC-135 Global Air Traffic

Management (GATM) modification. The satellite hardware system consists of a Collins SATCOM

2000 transceiver (Collins part number 822-1346-001), an electrically steered, phased array antenna

(part number 822-1369-001), as well as all wiring harnesses, connectors and mounting hardware. The satellite system interfaces with the C/KC-135 Operational Flight Program (OFP).

1.2 System Overview

The C/KC-135’s primary mission is to provide worldwide, day/night, adverse weather Aerial

Refueling (AR) to receiver capable United States (U.S.) and coalition military aircraft (potentially including unmanned aircraft). C/KC-135 aircraft are designed to provide robust, sustained AR capability to support global attack, air-bridge, deployment, sustainment, employment, redeployment, homeland defense, theater support to joint, allied, and coalition air forces, and specialized national defense missions. The C/KC-135 executes secondary missions such as cargo and/or passenger travel, aero-medical evacuation (AE) without impacting the primary AR mission.

The current Aero-I Inmarsat system was acquired to utilize improved Communication, Navigation and

Surveillance (CNS) technologies for access to Federal Aviation Administration (FAA) Air Traffic

Management (ATM). The critical satellite-based navigation technologies added with the Aero-I

SATCOM system included increased use of data links for pilot/controller communication, and improved surveillance to enhance both ground and cockpit situational awareness. Aircraft without the

CNS technologies are excluded from operating in airspace where separation standards and ATM procedures are implemented by civil aviation authorities. C/KC-135 aircraft modified with an Iridium

SATCOM system will mitigate capability gaps anticipated due to the planned Inmarsat discontinuation of the Aero-I satellite service after FY22.

Figure 1 provides a graphical depiction of the communication architecture between the C/KC-135

Global Air Traffic Management (GATM) equipped aircraft, and the other systems required for full communication with the CNS/ATM.

There are 359 C/KC-135 aircraft based throughout the U.S., Pacific, and Europe that will receive the

SATCOM replacement. The C/KC-135 SATCOM replacement SRD supports mitigating anticipated airspace restrictions within the global CNS/ATM. The SATCOM Replacement will consist of: a

SATCOM antenna, SATCOM transceiver (transmitter/receiver), and all associated Group A parts.

Projected time-line for C/KC-135 SATCOM Replacement fielding is FY21 with installs continuing through FY24.
