DIVIDE CRIPPLED TFs

All capital ships sunk


The CD results are cracy ... The interesting things is the BBs and CAs stood of the coast at 10K and the PBs closed which is realistic.


However there are issues
1) Lots of small guns doing small damage but with LOTS of shots resulting in high damage. ( not that there are many guns but they fire often)
2) The inability to surpress the defenders guns. It seems CDs fire rate has been bumped but withotu increasing the ships abbility to surpress the fire .
3) Capital ships will move away if seriously damaged (critical hit excepted) .

These 4 old 7" guns had a penetration of about 1.5 - 1.75" at 10K yards but i suspect the pre great war 1913 mod 5" did most of the damaage.

If cd guns were that good Japan is better of just taking them of there ships and wait for the US to impale theselves

[TulliusDetritus]

Why are you disturbing the crazy bear? [:)]

[Misconduct]

How the hell does a 180mm gun knock out a battleship? at most it would only destroy AA batteries but not penetrate? 

Edited: what Coastal gun hit the battleships, im assuming the 180mm guns?

All capital ships sunk

Finally! An accurate game result, and a perfect illustration of why real world commanders avoided CD installations like the plague. It's one thing to take on a few guns on the coast..., but a genuine pre-war built Coast Defense Installation was a ship killer.

[castor troy]

a loopsided, broken result. Unfortunetely this still can happen and I´m not sure it will ever be cured (or even can be cured). [:(]

[PresterJohn001]

Theres a couple of issues here, firstly is it reasonable for those cruiser sized guns to have sunk all the ships esp the BB's, who would have probably got the hell out of dodge
if damage started to mount up anyway. Its not like its difficult to um move away. So the result is very unreasonable.

Secondly whatever you think of the result, playing on a shifting battlefield is pretty difficult. Certainly if previous experience playing the game indicated that the force should be enough,
then to find the latest patch has dramatically changed the balance makes it pretty unfair. I'd be really pissed.

eh this place had less CD than Tarawa ( 4 7" guns with pre great war AP rounds and 5" guns of similar vintage). I think we will see it change when the Japanese spend PPs to buy out CDs and US BBs will hit the bottom

[John Lansford]

Someone has already tried invading Saipan and lost several heavy ships to the CD guns there.  I have to join with the crowd complaining about destroyer and light cruiser sized guns sinking heavily armored battleships; Tennessee got hit several times by a 6" battery off of (I think) Saipan and only lost one 5" turret to damage.  Even if for some reason the BB could not silence the battery (Tennessee destroyed that particular battery with several salvos of 5" shells), they could disengage at will.

[castor troy]

The disengage thing is what would make everything bigger than a row boat being able not to be sunk (or the chance being VERY small) by a CD battery that has WWI light cruiser gun size. It´s a difference if you´re moving around on the open sea engaging a shore battery or if you´re in a narrow fjord passing by in a couple of 100m distance to a shore battery without any room to maneuver.

[John Lansford]

That probably explains why so few ships were sunk or even heavily damaged by shore defense guns in the Pacific; the bombarding ships stayed out of the CD guns' range and shelled them in relative safety.  This nonsense of BB's being hit hundreds of times by small/medium caliber guns is ridiculous; any shore gun that fired on a BB quickly found itself on the receiving end of dozens, if not hundreds of 5" and larger shells accurately fired back at it.

[bklooste]

I dont think in this case the BBs or Cruisers would stay beyond the gun range since the shells cant penetrate the turrets , deck or belt.
 
The accuracy of these guns are absurd eg just these
 
BB Mutsu, Shell hits 118, heavy fires, heavy damage
BB Nagato, Shell hits 133, heavy fires, heavy damage
CA Chokai, Shell hits 78, heavy fires, heavy damage
CA Takao, Shell hits 79, heavy fires, heavy damage
 
If they hit 5% ( which is pretty high  per Gun, it would give a 10 gun salvo 50% chance per salvo) at 10K yards for a 5" gun thats ~8000 shells fired just on these 4 ships , barrel live of the 7" is about 300 ( -50 to -100 or so for test firings ) .

HORSEHOCKY! You are taking on a large number of 5.1, 6, and 7" guns that are part of an integrated coast defense system, not some "strays" dragged to an atoll shooting over open sights. Japan has some of these installations as well, at Tsushima and Tokyo Bay and such..., and the US should mess with them at their own peril. It's the fire control and accuracy that makes such places deadly. Look what happened to the Blucher when she took on 50 year old defenses at Oslo.

The shells caused uncontrollable fires that also disabled the fire mains. The ships thus were all doomed to explode. [:D]

[freeboy]

well, I attacked Babeldoad or whatevertheheck its called, all heavy ca.. base has been isolated for about 16 months or longer, thought I would just stop in to top off the damage my wekkly bombers been to the float planes there, and WHAT do you think happened?
I am not sure oi fthe last patch did something to the rutines BUT the results where not happy for me, on the other hand my pbem friend was estatic I am sure... we are talking really high results, that at night ove rthe horizon type shelling just shold not endure... after all what commander is going to sit there and watch a fleet decimated? let allone the results themselves for HUNDREDS of hits? on a capital ship.. its not like these guys dropped anchor!!! so, my .02 is the rutine may need to be toned down just a shade! lol

[John Lansford]

freeboy,
 
I had a TF made up of 5 BB's and 2 CA's bombard Mili, had recon flying daily on the place from Makin for two weeks, and LBA hitting it daily too.  Every single one of the BB's took significant (>25) System damage, plus secondary/AA gun damage.  The two CA's got chewed up bad too although none were sunk.  The results I saw indicated some port and supply hits, and about 100 casualties.  Mili is isolated thanks to Makin and Tarawa in my hands; everything bigger than a barge has been sunk trying to get there from Eniwetok, and my carriers roam CentPac with impunity in 4/43.
 
It's a combination of issues, I think.  Just because a unit has "CD" in its name shouldn't mean it has boresighted, super accurate weapons; that should be limited to places like Corregidor, Singapore, PH, etc.  If any ship started taking a lot of hits from a CD installation it would move out of range; if it had guns that outranged the CD it would normally stay out of range from the start and pound away.

Guess the Blucher is the example I used when I was talking about Fjords and open sea. The Blucher is definetely NOT what you should use when you talk about "coast" defenses.

CA Blücher was sunk by a torpedo battery that was detected too late in their approach path.

This is a map showing where Blücher had to go through. Not really like it is looking alike around an atoll and thousand miles of open water.

I was referring to the age of the weapons..., though if you look at Manila Bay or Vladivostok or Tokyo Bay or Palembang the example isn't far off either.

A torpedo battery that was part of the integrated coast defense system, like a fixed minefield in other locations. And the old Krupp 11" inch guns already had her in trouble and slowing when the torpedoes were fired.
