from 54 to almost 70 feet. Doing this also required the alteration of three existing decks. These modifications provided more cargo holds, space for a third set of twin Hagglunds 36-ton-capac- ity cranes, and a new 80-man deck- house for "surge" crews needed dur- ing periodic loading and unloading. The normal crew complement will be about 65, comprised of civilian and MSC Personnel. Other major additions included new ramps, fuel tanks, repair shops, and a helicopter landing platform aft. Reconstruction statistics, with the new 755-foot overall length and 69-foot 10'/2-inch depth, include a displacement of 28,249 long tons and a 32-foot lOVa-inch full-load draft. The ship's Sulzer diesel engine propulsion plant, a 7RND76M with a maximum continuous rating of 15,960 bhp at 112 rpm, will provide a service speed of 17.5 knots operat- ing at 85 percent of mcr. On-board capacities include 120,000 square feet for vehicles, space for 313 ammunition and re- frigerated cargo containers, 1.3 mil- lion gallons of drummed and bulk petroleum products, 84,933 gallons of potable water, and 615,083 gal- lons of fuel oil. USNS REGULUS National Steel The San Diego yard of National Steel and Shipbuilding Company recently redelivered the USNS Reg- ulus (T-AKR-292), a Fast Supply Ship converted for the U.S. Navy's Military Sealift Command. She and her sister ships are among the larg- est and fastest cargo vessels in the world, with an overall length of 946 feet and speed of 33 knots. The T- AKRs will be contract-operated by civilian mariners, and held in ready reserve status until needed for con- tingencies or used in Department of Defense exercises. These supply ships are former Sea-Land SL-7 containerships that will provide rapid sealift capability for the transport of military equip- ment and supplies from the U.S. to any part of the world. They are being converted to give them: roll- on/roll-off capability via MacGre- gor-Navire access equipment; self- sustaining cargo-handling capabili- ty using new 35-ton and 50-ton twin cranes supplied by Hagglunds; an emergency helicopter landing area; and side ports to facilitate rapid loading and discharge. The Military Sealift Command is responsible for providing the neces- sary sealift capability to rapidly supply military forces overseas and sustain them for as long as opera- tional requirements dictate. The MSC also operates auxiliary ships that deliver supplies to Navy com- batant ships while underway, ocean- ographic and survey vessels, and tankers and dry cargo vessels that deliver Defense Department cargoes worldwide. Bender Shipbuilding Wins $4.5 Million In Contracts Bender Shipbuilding & Repair Co., Inc., Mobile, Ala., has been awarded a $1.292-million contract by the U.S. Navy for the conversion and regular overhaul of YFU-79 (self-propelled harbor utility craft) to HLT-1 (helicopter landing train- er) with redelivery to the Navy in March 1986. Some of the modifica- tions include having the bow ramp welded in the closed position and operating equipment removed, all asbestos removed, and the pilot- house and accommodations located aft are to be modified and relocated forward. In addition, Bender has been awarded a $3.2-million contract by the U.S. Army Corps of Engineers, Vicksburg District, for the major conversion from steam powered to SCR diesel-electric to the dredge Jadwin. The routine overhaul and maintenance work will be per- formed concurrently. The duration of this project will be approximately six months.
