Post subject: | New Mexico Class Proposed Designes |
The USS New Mexico was the most advanced, and the best protected battleship in the world when she was commisioned in 1918. She attracted a lot of interest from foreign navies and ship designers, especially from Britain. New Mexico is known for her 12x14"/50 guns. In most ways, she was almost the same as the preceeding Pennsylvania class. However, that was not the case with some of the earlier designs. Most of the preliminary designs for the New Mexico had 16 inch guns in either 3 twin turrets, 4 twin turrets, or 5 twin turrets. The 16 inch guns had been designed and tested in 1911, and was considered ready to be put onto ships in 1913. However, the secretary of the navy did not want the ships currently ship classes that were under construction (Nevada and Pennsylvania) to be rendered obsolete with the introduction of 16 inch guns. So the upcoming New Mexico was a repeat of the Pennsylvania, shipping 12x14 inch guns. First up is the Design #4, which had 8x16 inch guns, and armor similar to the Pennsylvania class. http://shipscribe.com/styles/S-584/imag ... 84031c.htm USS New Mexico as rebuilt in 1929-1931: USS New Mexico in 1941 with the experimental measure 1A: [spoiler=Design #4 SS Report]USS New Mexico, United States of America, Super Dreadnought, laid down in 1915 Displacement: 28 906 t light; 30 698 t standard; 32 000 t normal; 33 042 t full load Dimensions: Length overall / water x beam x draught 608,50 ft / 601,50 ft x 97,60 ft x 30,00 ft (normal load) 185,47 m / 183,34 m x 29,75 m x 9,14 m Armament: 8 - 16,00" / 406 mm guns (4x2 guns), 2 048,00lbs / 928,96kg shells, 1913 Model Breech loading guns in turrets (on barbettes) on centreline ends, evenly spread, 2 raised mounts - superfiring Main guns limited to end-on fire 10 - 5,00" / 127 mm guns in single mounts, 62,50lbs / 28,35kg shells, 1913 Model Breech loading guns in casemate mounts on side, all amidships 2 - 5,00" / 127 mm guns in single mounts, 62,50lbs / 28,35kg shells, 1913 Model Breech loading guns in deck mounts on side, evenly spread Weight of broadside 17 134 lbs / 7 772 kg Shells per gun, main battery: 120 4 - 21,0" / 533,4 mm submerged torpedo tubes Armour: - Belts: Width (max) Length (avg) Height (avg) Main: 8,00" / 203 mm 435,00 ft / 132,59 m 10,00 ft / 3,05 m Ends: 13,5" / 343 mm 72,00 ft / 21,95 m 12,00 ft / 3,66 m 94,50 ft / 28,80 m Unarmoured ends Upper: 13,5" / 343 mm 435,00 ft / 132,59 m 12,00 ft / 3,66 m Main Belt covers 111 % of normal length - Torpedo Bulkhead: 4,00" / 102 mm 507,00 ft / 154,53 m 12,00 ft / 3,66 m - Gun armour: Face (max) Other gunhouse (avg) Barbette/hoist (max) Main: 18,0" / 457 mm 8,00" / 203 mm 13,0" / 330 mm 2nd: 1,00" / 25 mm 1,00" / 25 mm 1,00" / 25 mm - Armour deck: 3,50" / 89 mm, Conning tower: 16,00" / 406 mm Machinery: Oil fired boilers, steam turbines, Geared drive, 4 shafts, 36 674 shp / 27 358 Kw = 21,00 kts Range 8 000nm at 10,00 kts Bunker at max displacement = 2 343 tons Complement: 1 196 - 1 555 Cost: £3,286 million / $13,143 million Distribution of weights at normal displacement: Armament: 2 142 tons, 6,7 % Armour: 12 656 tons, 39,6 % - Belts: 4 961 tons, 15,5 % - Torpedo bulkhead: 900 tons, 2,8 % - Armament: 3 573 tons, 11,2 % - Armour Deck: 2 875 tons, 9,0 % - Conning Tower: 347 tons, 1,1 % Machinery: 1 437 tons, 4,5 % Hull, fittings & equipment: 12 671 tons, 39,6 % Fuel, ammunition & stores: 3 094 tons, 9,7 % Miscellaneous weights: 0 tons, 0,0 % Overall survivability and seakeeping ability: Survivability (Non-critical penetrating hits needed to sink ship): 44 246 lbs / 20 070 Kg = 21,6 x 16,0 " / 406 mm shells or 7,4 torpedoes Stability (Unstable if below 1.00): 1,00 Metacentric height 4,9 ft / 1,5 m Roll period: 18,6 seconds Steadiness - As gun platform (Average = 50 %): 69 % - Recoil effect (Restricted arc if above 1.00): 1,04 Seaboat quality (Average = 1.00): 1,57 Hull form characteristics: Hull has rise forward of midbreak Block coefficient: 0,636 Length to Beam Ratio: 6,16 : 1 'Natural speed' for length: 24,53 kts Power going to wave formation at top speed: 44 % Trim (Max stability = 0, Max steadiness = 100): 44 Bow angle (Positive = bow angles forward): 15,07 degrees Stern overhang: -3,00 ft / -0,91 m Freeboard (% = measuring location as a percentage of overall length): - Stem: 26,00 ft / 7,92 m - Forecastle (20 %): 26,00 ft / 7,92 m - Mid (50 %): 26,00 ft / 7,92 m (18,50 ft / 5,64 m aft of break) - Quarterdeck (15 %): 18,50 ft / 5,64 m - Stern: 18,50 ft / 5,64 m - Average freeboard: 22,25 ft / 6,78 m Ship tends to be wet forward Ship space, strength and comments: Space - Hull below water (magazines/engines, low = better): 85,3 % - Above water (accommodation/working, high = better): 155,3 % Waterplane Area: 44 394 Square feet or 4 124 Square metres Displacement factor (Displacement / loading): 98 % Structure weight / hull surface area: 204 lbs/sq ft or 996 Kg/sq metre Hull strength (Relative): - Cross-sectional: 0,94 - Longitudinal: 1,78 - Overall: 1,00 Hull space for machinery, storage, compartmentation is adequate Room for accommodation and workspaces is excellent Excellent seaboat, comfortable, can fire her guns in the heaviest weather[/spoiler] Here is the Design #1, which has 10x16 in five twin turrets on a stretched hull.

Very nice work! Does this mean a resumption of the USN BB drawings? |

It's possible, I dont have any new sources for the Delaware up to the New York classes. I might update the Pennsylvania, from which a lot on this drawing comes from. I might also do the New Mexico class and Tennessee class. I might also update the Colorado.
Looks like a beginning of a very interesting series. Looking forward to see further additions.
The USN had several interesting proposals that were considered. Some of them have been used in my Roman AU and my No Washington Treaty AU. Another interesting fact is that the Pennsylvania class could have been built with 8x15 inch guns.

I have added the USS New Mexico as rebuilt in 1931. I hope you like it, it has taken me the better part of 11 hours to draw. |

Fine job Will you draw the mid 40's version too? |

Nice work, its nice to see the alternative designs for New Mexico represented. Let's just be careful the what-if refits don't overwhelm the real never-weres in this thread. |

Post subject: | Re: New Mexico Class Proposed Designes |
You are correct, however, if I slap on some triple 14 inch turrets, I have the USS Pennsylvania as she appeared in 1931. So in a sense, I have made both a hypothetical refit, and a real life ship. |

Post subject: | Re: New Mexico Class Proposed Designes |
I have added the Design Number 1 and the USS New Mexico as commisioned in 1918 for comparison. I have also added a wip of the Design Number 103 which has 12x14 inch guns in twin turrets. |
