不如推算一下如果MkII用SC 300发射时能够达到多少?
另外还有一个疑点:
MKII的穿深数据
Armor Penetration with 1,938 lbs. (879 kg) AP Shell
.
Range Side Armor Deck Armor
17,200 yards (15,730 m) 14.0" (356 mm) 2.0" (52 mm)
19,400 yards (17,740 m) 13.0" (330 mm) ---
21,700 yards (19,840 m) 12.0" (305 mm) 3.0" (76 mm)
24,500 yards (22,400 m) 11.0" (279 mm) ---
26,000 yards (23,770 m) --- 4.0" (102 mm)
28,000 yards (25,600 m) 10.0" (254 mm) ---
29,500 yards (26,980 m) --- 5.0" (127 mm)
32,500 yards (29,720 m) --- 6.0" (152 mm)
Note: This data is from "British Battleships of World War Two" and is presumably for a muzzle velocity of 2,510 fps (836 mps). This table assumes 90 degree inclination and is based upon theoretical calculations performed in 1935, not actual firing trials.
下面两则是MkI的穿深数据:
Armor Penetration with 1,938 lbs. (879 kg) APC Shell
.
Range Side Armor Deck Armor
17,200 yards (15,730 m) 14.0" (356 mm) ---
18,000 yards (16,460 m) --- 2.0" (51 mm)
19,400 yards (17,740 m) 13.0" (330 mm) ---
21,700 yards (19,840 m) 12.0" (305 mm) ---
24,000 yards (21,950 m) --- 3.0" (76 mm)
24,500 yards (22,400 m) 11.0" (279 mm) ---
28,000 yards (25,600 m) 10.0" (254 mm) 4.0" (102 mm)
29,500 yards (26,970 m) --- 5.0" (127 mm)
32,500 yards (29,720 m) --- 6.0" (152 mm)
Notes:
1) This data is from "British Battleships of World War Two." This table assumes 90 degree inclination and is based upon theoretical calculations performed in 1935, not actual firing trials.
2) Note that the range necessary to penetrate 6.0" (152 mm) of deck armor is at or beyond the maximum range of guns firing SC standard charges at an elevation of 30 degrees.
——1935推算结果。
Side Armor Deck Armor
0 yards (0 m) 27.1" (687 mm) ---
10,000 yards (9,144 m) 16.5" (422 mm) 1.25" (32 mm)
15,000 yards (13,716 m) 13.9" (353 mm) 1.95" (50 mm)
20,000 yards (18,288 m) 11.7" (297 mm) 3.10" (72 mm)
25,000 yards (22,860 m) 10.2" (259 mm) 4.30" (121 mm)
30,000 yards (27,432 m) 9.0" (229 mm) 5.70" (145 mm)
This data is from "Battleships: Allied Battleships in World War II" for a muzzle velocity of 2,400 fps (732 mps) and is partly based upon the USN Empirical Formula for Armor Penetration and partly based upon official data.

诸位可以看到,MkII的穿深和MKI的第一组穿深数据几乎一模一样(总共只有一个数据,也就是17200码处的水平穿深差了1mm)。而且两组数据都来自同一出处,注明为1935年推算值(注释也一样)!难道相差二十年,初速提高16m/s威力竟然毫无变化吗? |
