The New Aircraft Carriers Larger than Ranger The contract base price for the two new aircraft carriers awarded to the Newport News Shipbuilding & Dry Dock Co., is $19,000,000 for each ves- sel, compared with about $15,500,000 for the Ranger. The contract time for completion is 36 months for the first vessel and 40 months for the sec- ond vessel, compared with 42 months for the RaAnceR. The time allowed for the new vessels is extremely short considering the various special fea- tures in connection with the work. The new vessels are of Over one- third more tonnage than the RANGER. The general dimensions of the new vessels and the RANGER are, respective- ly, approximately as follows: Length overall, 803 feet, and 765 feet; beam extreme, 112 feet, and 94 feet; draft, 20 feet 6 inches, and 24 feet 4 inches; displacement, 20,000 tons, and 13,800 tons; number of officers and crew, 1830, and 1460. Complete contract plans and spe- cifications were furnished for the RANGER at time of bidding, while only preliminary specifications and incom- ‘plete plans were furnished for the new vessels. Contract plans and specifica- tions must be prepared by the ship- yard and will take several months. After approval by the navy depart- ment these plans and specifications will become a part of the contract. The RANGER was started under a 44- hour week, later changed to a 40-hour week and on Aug. 1, 1933, to a 32-hour week. The new vessels must be built under the 32-hour week. It, therefore, appears that the shipyard must do about one-third more work per ship within about two-thirds of the corre- sponding time allowed for the RANGER. Work in the drawing rooms com- menced immediately after bids were opened and is progressing as rapidly as possible. By special arrangement permission has been granted to work 48 hours per week on design until Feb. 1, 1934. The yard is now actually working 44 hours per week in order to hasten the completion of contract plans and specifications and the ordering of material with the objective of plac- ing work in the yard at the earliest possible date. The secretary of the navy has an- nounced that these two new aircraft carriers are to be given the names YorKrowN and Enrerprise. In the shipyard the vessels will have the des- ignation of hulls Nos. 359 and 360. The Todd Shipyards Corp. has com- pleted the installation of a five sec- tion floating dry dock at its Tietjen & Lang Dry Dock & Repair Co. plant, Hoboken, N. J. This dry dock is 492 feet long, 117 feet in breadth and has a lifting capacity of 10,000 tons. The new dry dock commenced opera- lod tion on Sept. 7. Dahlia, New Lighthouse Tender Launched nearinz completion at the yard of the Great Lakes Engineering Works, River Rouge, Mich. Bids for this vessel were opened on Feb. 15 last, and the lowest bid was $66,566. As shown in the accompayning illus- trations, this vessel was built under cover and launched by rolling to the water’s edge and on to the floating dry dock. The launching took place Aug. 26. She will be completed Te lighthouse tender DAHLIA is about the middle of October. The principal dimensions of the new vessel are: Length overall, 81 feet, 2 inches; length between perpen- diculars, 72 feet; breadth molded, 20 feet; and depth molded, 9 feet, 6 inches. The mean draft is 6 feet, 6 inches, and the displacement at this draft is approximately 160 tons, allow- ing for a useful load of 20 tons. The bunker fuel capacity in diesel fuel is 6 tons. Speed of the vessel is rated at 7 knots under ordinary conditions. The main propelling machinery con- sists of one 4 cycle, six-cylinder Win- ton diesel engine with 10-inch diame- ter cylinders and 14 inches stroke. This engine, directly connected to the propeller, develops 235 horsepower at 350 revolutions per minute. For heat- ing there is one Almy watertube boiler of 77 square feet heating surface, op- erating at 80 pounds pressure and burning oil.
