In planning the structural details the greatest care has been exercised to provide a hull which: shall combine with lightness the strength and stiff- ness necessary to successfully with- stand the severe shocks which the vessel may be called upon to under- go, and particular attention has been paid to the longitudinal strength of the vessel and to the strength of the water-tight bulkheads, that they may be able to withstand the pressure due to the flooding of any compartment and thus avoid endangering the ves- sel as a whole. The hull will be built of steel throughout. The ldéngitudinal bulk- heads will be worked continuous throughout the engine and_ boiler Spaces, one on each side, extending from the bottom of the vessel to the main deck, and inclined slightly in- board at the top. In order to avoid any break in the continuity of the strength of the vessel the upper and lower strakes of these bulkheads will extend well beyond the limits of the throughout the. boiler and engine room, an inner bottom will be worked, Five decks, designated as forecastle, main, berth, orlop and platform, re- spectively, will be worked, the main and. berth decks being continuous from stem to stern. Nickel steel pro- tection of 80 Ibs. per sq. ft. will be worked on the shell plating for the length bof the machinery .space in- cluding the dynamo room, extending from about 3 ft. 4 in. below the water line 'to about 9 ft. 6 in. above, abreast the engine and dynamo rooms and 6 ft.: 6: in. above, abreast the boiler rooms. At the forward end of the machinery space and the after end of the dynamo room, partial athwartship bulkheads of 40_ Ibs. nickel steel will be fitted, of the. same depth as the adjoining side pro- tection. Nickel steel protection. will 'also be fitted in wake of the steering engine. The battery consists of two 5-in. and six 3-in:. rapid-fire guns and two 21-in. submerged torpedo tubes. Two. submerged torpedo tubes. of -the side-loading type with all neces- sary accessories, including air com- pressors and accumulators, will, be in- stalled in the torpedo room forward, one on each side. Four torpedoes for 'each tube will be carried. 'The tWagazines have" béen. so ar- ranged that about half the total sup- ply of ammunition will be carried at each end of the vessel, and four am- "munition hoists driven by constant speed electric motors will del:ver am- munition to the guns.
