Naval Modular Automated Communications System (NAVMACS)

 

The Naval Modular Automated Communications System (NAVMACS) family (V1, V2, V3, V5 and V5A) was developed for various classes of ships and afloat commands to satisfy the requirements of Fleet and Task Force Commanders to meet command missions while providing accurate secure and expedient communications.

In the development of NAVMACS, prime consideration was given to reducing writer-to-reader time, operator workload and human error while providing reliable and secure communications through the automation of message processing and management functions

NAVMACS family design featured a modular architecture for hardware, software and functional capability based on command need. This modular concept resulted in lower technical risk, early and incremental fleet improvement, and quality hardware purchases. It also allowed for economical growth, common spare parts support, and economical software support.

NAVMACS V1:

NAVMACS V1 software was accepted in April 1979 and was installed aboard USS Mount Baker in November 1979. No Operational Evaluation (OPEVAL) was required. NAVMACS V1 was intended for use on the following classes of ships: AE, AGA, ARS, ASR, ATF, ATS, DD, FF-1038, LKA, LSD, LST, TAF, TAO and TATF. NAVMACS V1 was the first version of the NAVMACS family and is no longer in use.

NAVMACS V2:

NAVMACS V2 software passed OPEVAL in 1978, and was installed aboard USS Mount Whitney in April 1980. NAVMACS V2 was intended for use on the following classes of ships: AD, AFS, AGDS, AO, AOE, AOR, AR, AS, CG, DD, DDG, FF, FFG, LPA, and LPD. The Current NAVMACS V2 version is release 12.3.

NAVMACS V3:

NAVMACS V3 software passed OPEVAL aboard USS Richmond K Turner in 1979. NAVMACS V3 was intended for use on the following classes of ships: AD, AFGG, AGF, CG, CGN, DDG, and LPD. The current NAVMACS V3 version is release 5.1.0.1.

NAVMACS V5/V5A:

NAVMACS V5 was developed in four phases. NAVMACS V5 Phase A software passed shipboard Technical Evaluation (TECHEVAL) and OPEVAL aboard USS Mount Whitney in April 1986. Following completion of Follow-On test and Evaluation (FOT&E) in August 1986, all NAVMACS V5 platforms upgraded to Phase B1.

NAVMACS V5 Phase B2 upgrades began aboard USS Ranger in January 1987. NAVMACS V5 Phase B3 upgrades began aboard USS Constellation in July 1989. NAVMACS V5 was intended for use on the following classes of ships: CV, CVN, LCC, LPH, LHD, LHA, DDG-51, and numbered fleet flag ships

NAVMACS V5A software was developed during 1988, using NAVMACS V5 Phase B2 for the UYK-44 computer as the baseline. NAVMACS V5A was intended for DDG-51 and CG-62 (AEGIS) class ships.

NAVMACS V5 and V5A are no longer used in the Navy, and have been replaced with more modern technology.
