    No an anti-ship missile modern day can beat Iowa Battleship-class ?

    Iowa Class: Armor Protection

    One of the main characteristics of a battleship is its ability to withstand an attack. Few ships from the past and no modern ships can equal the survivability of the Iowa Class Battleships. The decision of where to armor and how much armor to use is a very complicated and sometimes frustrating process. Simply adding armor can not be done since this greatly increases weight and reduces the top speed of the ship. The process of protecting a battleship is an art that has been perfected over decades of battleship design. Iowa Class Battleships are an excellent example of superior armor protection and high top speed.
    The armor systems of the Iowa Class ships can be divided into two basic sections. First is the above water armor, which is designed to protect the ship against gun fire and aerial bombing. The second is the below water armor (side protective and triple bottom armor), which is designed to protect the vessel from mines, near miss bombs and of course, torpedoes.

    All the systems needed to keep these ship's combat effective such as magazines, engineering spaces, steering, plotting rooms, command & control, weapons, etc. are protected by heavy armor. The armor box, referred to as the citadel, extends from just forward of Turret 1 to just aft of Turret III. The top, sides and ends of the citadel are heavily armored, however the bottom is not ballistically protected. Critical systems located outside the citadel such as the turrets, conning tower, fire control, directors, etc. are armored extensions of the citadel...

    The Armor:

    Armor
    The second basic factor, after firepower, to be considered was Iowa class armor. The armor scheme was a copy of the armor used on North Carolina and South Dakota, only thicker. This armor could, in theory, stop a 16-inch shell coming in at a 45-degree angle. There was some idle talk about making the Iowa class armor tough enough to stop an 18-inch shell, but BDAB dropped the idea when it realized how much more weight and redesign work it would take.

    Nickel-steel was used to manufacture the armor. This type of steel is a kind of stainless steel which has the added benefits that it does not corrode quickly, but bends easily. Nickel-steel was not a new material. From the start, armored warships like USS Indiana (BB-1) used this type of steel. One 17 1/2 inch belt of the nickel-steel ran from the deck to the below water line on both sides of the ship and covered the middle 2/3 of the ship. Eighteen inch plates were used in the turrets and 11 1/2 inch plates were placed on the decks.

    It is interesting to note that much of the Iowa class's armor is just as thick as battleships built 50 years earlier. Wisconsin and her sisters, however, benefitted from advances in steel technology that allowed mills to forge the steel at higher temperatures and heat treatment, which in turn produced a much higher quality steel that was stronger and more elastic. Two plants, Bethehelm Steel's main mill in Bethehelm, PA and Luken Steel's Coatsville mill just ouside Phildadelphia, manufactured most of the armor plating. For the turret plate, however, a special forge was constructed just for the Iowa-class at the Charleston Ordnance Works in Charleston, WV...

    Thus, all of today's anti-ship missiles (example: Kh-35/31, RGM-84, Exocet, C-803, YJ-18, LRASM, P-270/700/800/1000, NSM, TLAM Block IV, Brahmos.....) can not do anything with the armor of Iowa, unless they attack in large numbers (100 or more)

    ​​​​​​​Jsow and Jsow-er can, they have a front HEAT warhead in front of FTB modern HEAT can cut through 1000-1200 mm RHA easily
    The AGM-154C uses an Imaging Infrared (IIR) terminal seeker with autonomous guidance. The AGM-154C carries the BROACH warhead. This two stage warhead is made up from a WDU-44 shaped augmenting warhead and a WDU-45 follow through bomb. The weapon is designed to attack hardened targets. It entered service with the US Navy in February 2005. The BROACH warhead is a multi stage warhead. The two stage warhead is made up from an initial shaped charge, which cuts a passage through armour, concrete, earth, etc., allowing a larger following warhead to penetrate inside the target

        I think a lot of AShMs could. A direct hit, or even a near miss from a Mk82 would destroy an MBT, so I'm pretty sure it would cause damage beyond the armour of any battleship too and plenty of missiles have 500lb class warheads, then you have stuff like P-700s, Kh-22s and DF-21Ds. I certainly wouldn't volunteer to be inside the ship while all that is hitting it.

          In 1945 the Yamato was transformed into a Coral Reef by six 1000 lbs bombs and eleven MK13 torpedos, but somehow in the 21st Century an Iowa would survive an encounter with a handfull of modern day heavy Ashms... Right.

            AARGM-ER, ASM-3, RAMPAGE can easily penetrate the citadel or the deck

              Alternatively, a harpoon to the radar system of IOWA, then BLU-116 or BLU-109 can penetrate the deck, even WWII AP bombs can penetrate the deck, modern bunker buster bombs can do better.

                  If armour belt was useful against modern anti-ship weapons, then modern warships would have armour belts.

                  Thick belt armour might help a battleship against some missile hits in some circumstances, but overall it would be minimal help.

                    edit. Man, this new software sucks. What the heck is wrong with this?

                      especially since you can't cover radar and optics inside armor bell, a blind ship is pretty useless.

                      Btw, i just realized now that OP didn't actually want a discussion, he only started this thread so it can pamper to his agenda that Russian anti ship missiles are far superior to the Western counterpart. He actually posted the same thread here:
                      https://www.alternatehistory.com/for...-class.393781/

                      so that he can post this at the end of the thread.

                        air launch ballistic missile will do the job

                          The Franco-British SCALP/Storm Shadow missile uses the same warhead.
