(U) Enhanced Manpack UHF Terminal (EMUT) (aka Spitfire)

Description (U):

(U) The AN/PSC-5 will provide DoD users with Half Duplex (HDX) SATCOM and line of sight (LOS) communications for ground applications in the UHF band from 225.0 megahertz (MHz) to 399.995 MHz. The EMUT modes provide narrowband voice, 5-kilohertz (kHz) and 25-kHz non-Demand Assigned Multiple Access (DAMA) operation in accordance with MIL-STD-188-181, 5-kHz DAMA and Demand Assigned Single Access (DASA) operation in accordance with MIL-STD-188-182, and 25-kHz DAMA and DASA operation in accordance with MIL-STD-188-183. The AN/PSC-5 is a non-development item (NDI) which includes embedded Communications Security (COMSEC) and is the DoD choice to replace all UHF manportable and vehicular SATCOM radios, the AN/PSC-3, AN/PSC-7, and all other non-DAMA UHF ground terminals. EMUT will employ burst transmission over the FLTSATCOM and UHF Follow-On (UFO) satellite systems to provide shared use of 5- and 25-kHz channels on existing and planned satellite transponders.

(U) The EMUT provides both narrowband (2.4 kilobits/second (kbps)) and wideband (16 kbps) voice processing, and will accept digital data Input/Output (I/O) at data rates between 75 bits/second (bps) and 19.2 kbps. The terminal contains embedded data and voice encryption/decryption and is interoperable with TSEC/KG-84A, TSEC/KYV-5 (Advanced Narrowband Digital Voice Terminal [ANDVT]), and TSEC/KY-58 (VINSON). Crypto bypass will be available for transmission of unencrypted voice and data.

(U) EMUT-compatible baseband I/O devices include, DMDG and AN/PSC-2 and PCs. The EMUT will interoperate with other UHF DAMA SATCOM terminals, which have been certified by the Joint Interoperability Test Center (JITC), and with other radios from the UHF LOS and VHF LOS families. The EMUT will interoperate with the above radios when they interface to any of the following baseband I/O devices: VINSON, ANDVT family, and KG-84 cryptographic equipment.

(U) The Air Force plans on procuring a total of 1,127 EMUTs from FY 97 - FY 00.

User Impact (U):

(U) Interoperable UHF DAMA SATCOM on 5-kHz and 25-kHz unprocessed satellite channels is a JCS requirement per CJSCI 6251-01 dated 31 Jul 96, MCM-89-94 dated 28 Jul 94, MCM-105-94 dated 31 Aug 94, and MJCS-36-89 dated 28 Feb 89. Failure to equip our forces with UHF DAMA SATCOM could lead to denial of UHF SATCOM channel access. Beyond Line Of Sight, e.g., SATCOM, communications are of increasing importance as DoD forces continue to modernize and perform missions that previous communication systems can no longer adequately support.
