    Very interesting.
    When I was in the USMC, in Vietnam, the word of mouth was the
    Effective Casualty Radius of the New Jersery's "Big Thunder"
    wa 1,000 meters. Hmmm, I guess that was pretty false.

    Why would the Navy decommission battleships? Unlike planes, you can't
    shoot down a 16-inch shell.
    There was an awkward comparison, during the 1991 Gulf War, between
    battleships and carriers.

    Two battleships, operating in the northern Gulf, managed to deliver -
    between them - about 1,100 16″ shells in the direction of the enemy, in 80-odd fire missions.

    That translated to a bit over 2,000,000lb of ordnance, which sounds like
    a lot. Unfortunately, very little of it was explosive: so it added up to
    about 150,000lb of TNT in total sent targetwards. Worse, accuracy wasn’t great, and spotting and correction frequently unavailable: of those
    eighty-odd missions, only about a dozen were found to have achieved
    anything significant (firing blindly at desert hoping something
    important was under the shells, turned out not to be very effective).

    Worse, to get the two battleships into gun range of Kuwait, required a
    force of thirty ships (two dozen minehunters and their support vessels,
    plus protective escort) working for three weeks; not a lot of strategic surprise happening there. In the process, the USS Tripoli and USS
    Princeton both hit mines, suffering significant and expensive damage.
    And during the bombardment, the Iraqis managed to get a Seersucker
    missile launched in the Missouri’s direction (fortunately, to be shot
    down by HMS Gloucester)

    Compare that to one smaller, old carrier that - because the Gulf was so
    crowded - was operating down in the Red Sea. The USS Saratoga’s air wing delivered 4,300,000lb of ordnance to Iraqi targets without loss; twice
    as much as two battleships combined. Worse, because air-dropped ordnance
    is much more destructive than battleship shells (a 16″ HC shell has the equivalent of 120lb of TNT inside; a Mk 84 bomb, of similar weight, has
    the equivalent of about 1,200lb of TNT) her weaponry was considerably
    more effective: in terms of explosives delivered, the Saratoga donated
    roughly 2,500,000lb of TNT-equivalent to Iraqi targets - nearly twenty
    times as much as the two battleships together.

    And the Saratoga did that from the Red Sea, 700 miles from her targets;
    needing no minehunters to clear lanes and a Fire Support Area for her;
    getting no escorts damaged or sunk.

    After the Gulf War, it was very clear that airpower had seriously
    surpassed battleship gunnery: the ability to land small explosive
    charges (each 16″ shell was about as powerful as a 250lb bomb) in the
    vague vicinity of a platform at a range of 20 miles, turned out not to
    be of much use, and certainly wasn’t worth the huge cost in manpower, maintenance, and escort/protection needed, compared to carrier
    aviation’s ability to strike much harder, at far greater range, with
    much more responsiveness.

    “A 16″ HC shell has the equivalent of 120lb of TNT”
    I found it hard to believe a massive shell like this would only have
    ~120lb of explosive, so looked it up.

    Normally would just use Warthunder data but the Iowa class is not in
    game yet, but Wikipedia has the 16″ HC shell listed as 1,900-pound (862
    kg) and a charge for the Mark 13: 153.6 lbs. (69.67 kg) Explosive D.

    So basically yes, only about 120lb TNT equivalent; which to be fair is
    still enough to do an awful lot of damage if it hit anything but I lot
    less than I expected.

    So today I learned moment

    big guns is to deliver explosives downrange; thus the less of other

    Battleship shells were designed to penetrate very thick, hardened steel
    armour then explode once it got through.

    The shells had to be made very strong so they would not break apart when hitting the armour hence there was only a small volume left for explosives.

    They could have made shells with a much larger explosive filling against unarmoured targets but I guess the infrastructure to do that no longer
    existed.

    Reading about the recommissioning process, they did consider making new
    shells that contained hundreds of bomblets to spread out over a large
    area and do damage to lightly protected areas, but as the answer
    indicates; far from the best way of delivering HE to a target even 40-50
    years ago.

    I knew the primary aim for battleships to defeat other heavily armored
    ships but knew they also carried non-AP shells with more HE for hitting
    lightly armored targets like smaller ships or ground bombardment.

    In the game I play the Hood only carries Semi-AP and full AP, but
    figured they might also have some lighter shells with more explosive but
    guess that is what secondary batteries (and escort vessels) are for

    Battleship guns were designed to shoot heavy shells at high velocities.
    They are not really good at shooting low velocity, lighter shells for
    shore bombardment. They are more like tanks with high velocity direct
    fire guns than self propelled artillery with indirect fire howitzer
    guns. It would be very expensive to restart making shells from scratch
    designed with a large high explosive charge. I suspect all the shells
    used after WWII were made during the War

    All weapons and tactics have their weaknesses, for instance modern infantry shooting from cover is what skirmishers have always done, but they were too vulnerable to cavalry lances to make it the standard practice. The Phalanx
    or solid line of spear or bayonet armed infantry could usually resist a
    charge, see Waterloo. Ukraine shows a limit to air power when the defense is stronger than the offense.

    The new US battleships of the 30's and especially 40's shifted the armor / armament / propulsion weight compromise to enable accompanying aircraft carriers that could exceed 30 knots. War games during the 20's and 30's had already shown carriers superior during daylight, battleships at night;
    without radar or night vision a task force needed both. The first US
    carriers were built on partially completed battlecruiser hulls minus the
    armor weight, which made them very fast, 33 kts. https://en.wikipedia.org/wiki/USS_Lexington_(CV-2)

    The final Iowa class managed to combine battlecruiser speed with full battleship armor. The battleships struck at Pearl were all older and far too slow at around 21 kts to keep up with carriers, so their temporary loss
    didn't hurt much. Once they had been repaired and upgraded we made good use
    of them. https://warfarehistorynetwork.com/article/clash-at-surigao-strait-the-last-battle-line/

    The question of how they would have fared versus Yamato remains open.
    American computerized fire control allowed accurate gunnery while turning, while Yamato's more manual system needed both own ship and target running straight. The destroyers that helped turn back Kurita learned that but I haven't seen if the US battleship skippers would have broken from their
    battle line soon enough.
    https://www.navalgazing.net/Spotting

    http://www.navweaps.com/Weapons/WNUS_16-50_mk7.php
    Battleships were optimized to fight other battleships, shore bombardment capability was a free bonus. The HC shells were meant to damage the superstructure or less heavily armored cruisers or aid the ship's smaller secondary armament to repel destroyers on torpedo runs. They did little more than scar the paint and spray fragments when they hit thick armor, while the armor piercing shells would merely punch holes in unarmored smaller ships or the unarmored ends and superstructure of battleships, like a solid
    cannonball. Disabling the superstructure's spotters, rangefinders and radar severely degrades long range gunfire accuracy, Bismarck's for example.

    Battleships tended to fight to the death, leaving no evidence of damage to
    the loser. Here's an exception, the enemy battleship sank first. http://www.navweaps.com/index_lundgren/South_Dakota_Damage_Analysis.php
    The 14" Japanese AP shells contained 24.5 Lbs of explosive, enough to break
    the shell into fragments meant to release high pressure steam within the armored "citadel" and cook the crew. The HC held 63.4 Lbs of explosive,
    again the high speed flying fragments did the damage. The Japanese 14" antiaircraft shell was a huge firework that spread incendiaries in front of approaching aircraft.

    How well did USS New Jersey perform in Vietnam?



    This happened when I was stationed in the Philippines.

    I was in a bar with my best friend. We were dressed in civilian clothes.
    This was good because of bunch of Marines were in the bar and the Navy
    and Marines didn't always get along.

    After a while a bunch of Sailors came into the bar. We could see by the
    patch on their uniforms that they were off the New Jersey. The Sailors
    walked up to the bar and I saw one of the Marines start to walk over to
    them. I thought, “Oh hell a fight is going to start.” But to my
    surprise, when he got to them, he told the bartender that as long as
    they were in that bar all of their drinks were on the Marines. Needless
    to say, the sailors and myself were very surprised.

    The Gunny said, “My men and I were trying to take a hill that Charlie
    had dug tunnels into. We had called in air support but they had nothing
    on hand that could drive Charlie out of his tunnels. The New Jersey had
    been monitoring the channel, and they ask if we could use a bombardment.
    We gave them the grid coordinates, and then they told us to pull back
    down off the hill. It was just a few minutes and hell rained down on
    that hill.”

    He said that in all his years in the Corps he had never seen or felt
    that power. He said that they hit the hill for about 15 minutes. When
    the smoke and dust had died down, the top 20 feet of the hill was
    GONE!!! He said, “That saved a lot of his men’s lives that day so their drinks were on the Marines.”

    Below is a picture of the Jersey when she was in Subic Bay. The others
    are pictures I took inside a 16 inch gun turret, It was not open to the
    public but being a old navy salt, I knew how to sneak into it.

    Concentrating the torpedoes on one side nearly doubled their effect because
    to prevent capsizing the top-heavy ship needed to counterflood the other
    side. The heavy side armor on Yamato and Musashi had a weak joint between
    its upper and lower sections that even lightweight aerial torpedoes could
    tear open.

    If Yamato had entered Leyte Gulf the continuous maneuvering to avoid aerial attack would have degraded accuracy against US battleships. The rapidly approaching US fleet carriers would have ensured that Yamato never left.

    Thank you Jim. Fascinating source and account.
    "Mount #10 firing Mark 32 fuzzed projectiles was the first to fire and
    the leading plane received a direct hit from what was believed to be the
    first projectile fired. It disintegrated in the air, and the Rangefinder
    of Sky 4 reported that at one instant he was looking at an airplane and
    the next instant all he could see was a propeller and radial engine
    flying through the air with no plane attached to it. Five-inch fire was
    then shifted to the second plane, which by this time was also under fire
    from the 20 and 40 mm guns as it moved up the port quarter towards the INTREPID. This plane was also shot down in flames"

    I do not mean to quibble.
    But logic indicates to me the "fuzzed" failed, and a rather lucky
    direct hit demolished the plane.

    In contrast Japanese battleships placed too much reliance on their
    over-rated 25mm AA gun and were taken out without excessive aircraft
    losses. I've read that there was cross-confusion over which plane each

    "U.S. losses were 10 aircraft and 12 pilots and aircrewmen."

    Concentrating the torpedoes on one side nearly doubled their effect
    because to prevent capsizing the top-heavy ship needed to counterflood
    the other side. The heavy side armor on Yamato and Musashi had a weak
    joint between its upper and lower sections that even lightweight aerial torpedoes could tear open.

    If Yamato had entered Leyte Gulf the continuous maneuvering to avoid
    aerial attack would have degraded accuracy against US battleships. The rapidly approaching US fleet carriers would have ensured that Yamato
    never left.

    As to comparisons of WWII BBs, I find the following site outstanding.

    http://www.combinedfleet.com/baddest.htm

    Has great details and evaluations about:

    Guns
    Armor
    Underwater Protection
    Fire-Control
    Tactical Factors
    Secondary Armament: Anti-ship
    Total Anti-Aircraft Suite
    Operational Factors

    As to fire control, I often think of the Japanese BB at Surigio St
    steaming out of the narrows before dawn, seeing some possible
    lightening in the far distance,
    and suddenly hit by first salvo of 16" AP

    Nothing the IJN had could come close to that.

    We'll never know how one or more Iowas would have fared against Yamato. I believe it could have gone either way depending on conditions and luck,
    which was a major factor in BB duels. A surface force that included them was sent against Yamato north of Okinawa but the carrier planes struck first.

    Luck: Bismarck's rudder, a parting shot at maximum range that slowed Scharnhorst, these two: https://www.guinnessworldrecords.com/world-records/longest-range-hit-by-a-ships-gun
    Washington being concealed behind burning South Dakota, cruiser shells disabling Graf Spee's kitchen and oil purifier but not much else, several German commerce raiders suddenly pounding warships that strayed too close to investigate them.

    The Pacific war began with an attack by carrier air instead of battleships
    and continued that way except for night actions around Guadalcanal - the
    result of US daytime air power - and the desperate last stands at Leyte
    after Japan had lost its naval aviation.

    John Lundgren's analysis of this battle near Guadalcanal, based on evidence
    not available for the official report, speaks very highly of the accuracy of
    US radar fire control. http://www.navweaps.com/index_lundgren/kirishimaDamageAnalysis.php

    "The most important piece of new evidence was supplied by Lt.Cdr. Shiro
    Hayashi who was Kirishima's Chief Damage Control Officer and before the ship sank he sketched a drawing of the hit locations suffered by his ship."
    "Ikeda shows 20 major caliber hits and seventeen smaller caliber hits..."
    The US estimate was 8 main gun hits, about 10%, which is reasonable for the relatively short range. It appears that shots observed as splashes were very close and struck underwater.

    In the battle off Samar Yamato may have scored a main gun hit or a very near miss that shook loose a cloud of boiler soot at very long range; I haven't
    read much of Lundgren's book on that battle yet. Once the US ships began dodging the Japanese couldn't hit them until within range of the US 5" guns, which on the destroyers had computerized fire control like our BBs. It's possible that a US carrier's 5" shell severely damaged or sank an IJN heavy cruiser by detonating its torpedos. The Japanese weren't interested in preserving records of their defeat so much is still speculation.
