U.S. Navy: The Electric Shi weight distribution, increased redundan- cies and survivability, and better fuel efficiencies. As the USS Arleigh Burke (DDG-51) design manager, he pushed the advanced integrated electric propul- sion plant; as commanding officer of Carderock Naval Ship Research and Development Center, he believed elec- tric drive was one of several "technolo- gy clusters" that needed to be pursued. That was 20 years ago-yet electric drive has not been installed in any major in- service or in-production Navy warship. Meanwhile, perhaps mirroring the Navy's mid- to late-19th-century experi- ence, other naval powers are investigat- ing the possibilities. For example, the Royal Navy is installing electric drive in its Albion-class amphibious warships and has selected the advanced WR-21 intercooled and recuperative gas turbine. We Offer Marine HVAC Solutions Based On 40 Years Of Engineering Excellence. And That's Not All. For nearly half a century, Cruisair and Marine Air Systems have been the fore- most names in marine HVAC technology. In 1999, we brought these two well- respected brands together with the formation of Taylor Made Environmental. Today you can look to us for a complete range of turnkey air conditioning and heating solutions, for circulated-water, seawater-cooled and air-cooled applications. Cruisair and Marine Air Systems products are designed by professional engineers who understand the unique requirements of the marine environment. They're built at state-of-the-art plants by skilled craftsmen who take pride in their work. They're backed by our extensive applications engineering group, and sustained by our worldwide network of factory-trained sen/ice dealers. So give us a call or send us your specs, and let us show you how we can solve your next marine HVAC job. fruisair r^fr' H ©Taylor Made ENVIRONMI /VIARINfc/IIR SYSTEMS , A\mm A-01 51 A-0152.

As long as the focus remains on the hull. mechanical, and electrical (HM&E) aspects of specific ships, suc- cess will elude the Navy. But if it articu- lates what an all-electric Navy could be and puts programs and resources in place-for various future technologies and systems as well as IED and IPS- success will be much more likely. In short, it must embrace IED and IPS as catalysts for the wide-ranging, "leap- ahead" warfighting capabilities that President George W. Bush and his advisors seek for the Navy. In January 2000, then-Navy Secretary Richard Danzig announced that the Zumwalt destroyers would be built with IED and IPS. A year earlier, he endorsed a Naval Sea Systems Command "Com- mon Integrated Electric Drive" report calling for a corporate approach to ensure that technologies developed for one platform type can be applied to other platforms. "Changes in propulsion systems are fundamental and of funda- mental importance," Secretary Danzig noted in his DD-21 announcement. "We are moving forward to embrace a tech- nology-electric drive technology-and the integrated power system that comes with it, to drive Navy ships." Thus, a lot hangs on the future of the DD-21. To be sure, there remain hotbeds- maybe "rice bowls" is more apt-of inter- est in IED and IPS in and out of the John Crane-Lips Marine Propulsion Systems Managing your moves Thrusters Easy mounting Robust and flexible design High thrust to power ratio Retractable versions Underwater mountable versions John Crane-Lips Americas 3617 Koppens Way Chesapeake Virginia 23323 USA Tel.: +1-757-485-5275 Fax: +1-757-487-3658 Circle 271 on Reader Service Card or visit www.maritimereporterinfo.com Podded propulsion units and integrated stern propulsors will contribute signifi- cantly to wake reduction (which will help nullify advances in space-based multi- spectral sensors), overall propulsion effi- ciency, acoustic stealth, and maneuver- ability.
