Scaled up destroyer hulls and WW2 long and thin cruiser hulls are pretty much the same thing. About a 9 or 10 to 1 shape. The current cruiser hulls are about the same size and shape as their WW2 light cruisers.-Destroyer hulls were long and thin, typically 10 to 1 often. The long - thin shape allowed for higher speed, with 36 to 38 knots typicalThe 1918 WW1 era Clemson Class DD were 314′ x 30′ 1200 tonThe 1934 pre WW2 Mahan Class DD were 341′ x 35′, 1500 tonThe 1942 WW2 Fletcher Class DD were 376′ x 39′, 2050 ton.Cruiser hulls were also long, but nearly as thin, likewise 10 to 1 moving towards 9 to 1 by WW2.The 1918 WW1 era Omaha class CL were 556′ x 55′, 7050 tons. Truly a scaled up DD.By 1934, the Brooklyn calls CL were 606′ x 62′, 9767 tons.The 1942 WW2 Cleveland Class CL were 600′ x 66′, 11744 tons.-Post WW2 hulls continued to grow for destroyers as the traditional gun cruiser type was discontinued, their mission moving to what were first called Destroyer Leaders, then Frigates before settling on Guided Missile Cruiser.-The 1958 Charles Adams DDG class were 437′ x 47′, 3277 tonsThe 1959 Leahy DLG/CG class were 533′ x 55′, 7800 tons.Then came the Gas Turbine Spruance Class destroyers of the 70’s. A large hull, often criticized for being under armed.The 1972 Spruance Class DD were 529′ x 55′, 8000 tons.This hull became the basis of the both the Ticonderoga Class CG and the Burke class DDG (as well as the Kidd Class DDG)Ticonderoga Class CG 567′ x 55′, 9800 tons full loadKidd Class DDG 563′ x 55′, 9783 tons loadBurke Class DDG 505′ x 66′, 8900 tons full load-

Well the newest US Navy Destroyer DD-1000 Zumwalt is 600 feet longand the Ticonderoga Cruiser is 567 feet long - it’s sort of mute as they both prove to be capable of the same duties it seems - so unless a design change comes along I say not a need to build more Ticonderoga class ships.

In the US it can vary a lot. The smallest I know of was the SW-1 at only 600hp. There was a few small industrial switchers that were even smaller. As for today's power about the smallest is the SW1000 at 1000 hp. ( not a lot made) . Most of the smaller units range between 1500hp to 2500hp. But the big power is an other story. From as much as 3000hp. to 6000hp. The largest that was ever built (that I know of was Union Pacific's Big Blow gas turbine it WAS 8500hp.!!! Two of them were saved at museums the #18 and the #26 neither of them run. The biggest running loco would be the last DD-40AX they were built at 6900hp. On the first units but it did not work that will. I heard they ran too hot. And they were derated down to 6600hp. One is still run as far as I know of #6936 on UP restored fleet in Wyoming. But most of the big power is between 4000hp and 5000hp. It seem when they try to break the 5000hp mark it can be asking for short life spans on the power and more maintenance issues and be very expensive. Over time the engine blocks have gotten larger. As the case of EMD's, the early ones were the 567's then came the 645's then came the 710's. what that is if you don't is the cubic inch PER CELINDER!! And there was very few 8 celinder units most have 12 to 16. There was some as much as 20! (SD-45). The SD-45's ran the 645 power unit. Most of the SD-45's have been retired. The SD-45 was rated at 3600 hp. What I understand was there was a problem with the crankshafts cracking. Some of the units had there engines removed and replaced with the same power as the SD40–2 at 3000hp. But they kept the original cooling system. To look at the unit it will look the same on the outside.
