External communications is a critical element in the U.S. Navy design and utilization of a ship's combat system. The communications antenna system is a key factor in attainment of reliable circuit performance and reduction of electromagnetic interference (EMI). To maintain pace with improved ship manufacturing techniques and construction materials, along with design efforts to reduce topside generated EMI/RFI effects, an improved antenna design must also evolve. With the ever increasing complexity in the integration of the topside environment, the RF aspects of the antenna designs must be augmented by detailed analysis of the operating environment and the mechanical design if the goals of reliability and quality performance are to be achieved. The Naval Electronic systems Command has developed a new “Broadband HF Communications Antenna.” This paper traces the design evolution and describes the processes in determining current design deficiencies, the design objectives to correct these deficiencies and the results obtained.

The Ship Energy Conservation Assist Team (SECAT) program was initiated in Fiscal Year (FY) 82 by the Naval Sea systems Command (NAVSEA) to demonstrate and introduce individual Ship Commands to known energy conserving techniques without adding equipment complexity or additional maintenance burden. The principal objective is to provide each ship with an energy consumption, coupled with recommended energy conservation strategies. The technique involves both in-port and underway monitoring and introduction of energy efficient machinery plant alignments, fuel consumption curve generation, and most efficient speed curves. The program has completed visits on six combatants and enjoys the support of both the Commander, Naval Surface Forces, U.S. Atlantic Fleet (COMNAVSURFLANT) and the Commander-in-Chief, U.S. Atlantic Fleet (CINCLANT). Plans are to perform SECAT on additional DDG 2 and FF 1052/1078 Class ships and initiate SECAT on additional ship types in FY 83.

BIONDI, RJKRUGER, BETHE AUTHORS: Mr. Roy J. Biondi:received his B.S.E.E. degree from the University of Illinois and has since taken additional graduate studies at The George Washington University. Currently
he is Head of the Ship Type Combat System Integration Branch (Code-6141) Naval Sea Systems Command. Prior to his present appointment he served as Radar Branch Head in the former Naval Ship Engineering Center (NA VSEC) and was responsible for development and production of shipboard radars such as the AN/SPS-48 AN/SPS-49 AN/SPS-52 and AN/SPS-55. His primary Navy Radar and Combat System experience was attained during his earlier career in the Navy's Bureau of Ships where he was the AN/SPS-48 Radar Project Manager as well as the Navy Tactical Data System Data Processing and Display Project Engineer - a total of twenty years of Navy Radar and NTDS experience. In addition to ASNE which he joined in 1977 he is a member of IEEE and ASE and has had several technical papers published on Radar Radar Processing and Transmission Lines. Mr. Bradford E. Kruger:is a Senior Member of the Technical Staff at ITT Gilfillan
Los Angeles Calif. He received his B.S.E.E. and M.S.E.E. degrees from the University of California at Berkeley in 1955 and 1956 respectively and has been with Gilfillan since then. For the past fifteen years he has been involved in the concept formulation and design of numerous radar systems for the Army Navy and Marine Corps. Most recently he has been the Principal Radar Systems Engineer for the SSURADS then the DDGX Program. In addition to ASNE which he joined in June 1980 he is a member of IEEE and holds several patents in Radar and Antenna Technology.

The best topside location for an antenna is on top of the highest mast on the ship, thus affording all-around coverage and minimum interference. However, usually only one antenna can occupy that site. Modern naval combatants have numerous antennas, and the necessary compromises in mounting all of them means that even the best site is often electro-magnetically compromised by adjacent structures and other antennas. A contrary approach is to mount larger antennas lower, and to design the ship to minimize blockage. This is “The UNIMAST Concept,” which argues for a single mast on which are mounted all the ship's major rotating surveillance antennas. The larger antennas rotate around the lower part of the mast, while lighter antennas, e.g., surface search, are sited above. This paper discusses the degradation of sidelobes due to present topside design and numerically relates degradation to Electronic Counter-Countermeasures (ECCM) performance. Removal of that degradation via the UNIMAST Concept requires that a device known as an Annular Rotary Coupler (ARC) be used. The development of just such a high power, wide-band ARC on a Navy-sponsored R&D contract is herein described. Also described is the potential backfitting of the UNIMAST Concept to existing ships; e.g., the DDG-993. Battle damage vulnerability of the UNIMAST Concept with respect to a conventional two mast design is addressed. It is argued that the UNIMAST Concept affords no degradation in vulnerability due to improved potential for protecting vital antenna parts.

COLEMAN, JAMES J.USNThe author is a graduate of the U.S. Navy Academy
Class of 1957. Prior to pursuing an advanced degree at Webb Institute of Naval Architecture he spent two years in destroyers and four years in submarines. Designated an Engineering Duty Officer (EDO) in 1966 he attended the Deep Sea Diving School and proceeded to Hunters Point Division of the San Francisco Naval Shipyard. Here he was responsible for the production efforts in the Deep Dive System MK 2 and the SEALAB III Program. While at Hunters Point he was also the 12th Naval District Salvage Officer and the Salvage Master during the raising of the nuclear submarine USS Guitarro which sank at Mare Island Naval Shipyard in May 1969. Following a tour on the Staff Commander Service Force U.S. Atlantic Fleet as the Fleet Salvage Officer he assumed command of the Experimental Diving Unit Washington D.C. in 1971 with additional duty at the Naval Ship Systems Command as the Supervisor of Diving. During this tour the Experimental Diving Unit conducted a world record 1600 foot wet hyperbaric dive. Relieved of this command on 1 October 1973 he presently remains as the Supervisor of Diving.
The office of the Supervisor of Diving, Naval Ship systems Command, is responsible for the development and testing of swimmer and diver equipment. The goal of the Navy Diving program is to enable the diver to work saf...
