Renown vs Baltic Squadron - april 9th 1940

[Jefgte]

neutral replay... 

The Baltic Squadron is a homogeneous squadron, perfectly training to confront & defeat a battleship. an elite unit

so, sink the Renown Alex !!!

so, I have all the data printed out, after some graphical work I'm ready to the dice-throwing 

The FFM-2007-crew knows the rules quite good (I think), its mostly an enchancement of the La Plata-Rules. If someone wants the exact rules, than I will translate them into English.

(its a kind of modification of this: http://members.tripod.com/fireonthewaters/fotw.htm)

@Harold:
Wenn ich fertig bin, kannst du dann die graphische Überarbeitung übernehmen?)

alex

[harold]

...ich könnte die graphische Überarbeitung zur 36-er-Teilung per excel machen, wenn du willst.
Die Schiffsdaten dazu hab ich ja schon von Jean-Francois bekommen, und für die Würfelei ein Tabellchen zu konstruieren - keine weitere Maloche, das.
Harold

[Huszar]

So, first 4 salvos done.

Study 20 makes a hit with the 3rd on Renown, well aft, near "Deckskante". No serious damage.
Ranown makes a hit on on Study 20 with the 4th, near the bow, near the waterline. Ship floods to the forward magazines.

so, I have to go to drink some beer, tomorrow I will continue!

alex

[t-geronimo]

Wollt ihr auch Powerpoints?

@ Alex:
Gunnery simulations on alcohol? 

Doesn't that let the hit rate become much lower? 

[Jefgte]

Study 20 is with 28cm guns...

...Hmmm, a bad hit in the bow... 


Oh Yeehhh Alex stop the game & drink some beers




Alex, can you add the time in your comment please

Jef 

[Huszar]

So, I'm back 

As usual, I make 5-Minute-Runs, in the first 5 minutes, there were only 3 salvos per ship (range-findig), in the next 5 minutes, there will be 4 salvoes, and thereafter 5 per 5 minute (range found).

Because of the bad weather and the range, I assume, that the hit-chance is at best 3%.
Secondary guns are not fireing, because they have not really a chance to get a hit.

[Jefgte]

Hallo Alex,

Important:

Jefgte's Shipyards did n't forget the Lutzow flooding lesson at Jutland.
When I make the studies of the Panzerschiffes in 1980 summer
All are equiped with a complet systeme to pump the water in the hull.

Here are the internal drawings made 27 years ago
I add little white & orange parts to indicate the place of the water pumps

In white, principal pump, In orange secondary pump.
4 principal & 4 secondary









As you can seen, the magasins are well protected by flooding.

------------------

The Von der Tann 15cm guns are made to help the 38cm in range, so, they must fire too.

[Huszar]

So, I made a summary of the hits on Renown (if its against copyright, please delete - I found it on internet - http://warship.all-model.com/HMS%20Renown.html)

the hits are:
1: 28cm
2: 28cm
3: 38cm
4: 28cm
5: 38cm
6: 28cm
7-17: 38cm

I will make also a summary for Study 20 (done)

(also the Excel-sheet with the salvos added)

[Jefgte]

Hallo Alex 

Good battle
8hits on German PBBs to 17 hits on the Renown

Study 20 is heavily damage, the pumps had much work to do

The hull of the Renown is a strainer.

Why Renown don't switch her fire to a 38cm PBB most dangerous for her ?


Well, who is still ready to fight? ...German or British


Jef

[Jefgte]

An other alternative for the constitution of the Baltic Squadron.



As you All know, Deutschland, Admiral Scheer & Admiral Graf Spee are sistership.


You can process identicaly and choose 1 class of Baltic Battleship.

3 Study 15 or 3 VdT or ... the most powerfull 3 Study 21

3 study 21 is the most powerfull Baltic Squadron
3 Study 20 are built in place of Deutschland Class & rebuilt in 1936,37,38 in Study 21.

The Baltic Squadron could have in 1939 3 Baltic battleships
15200T
24 kts - 3500nm range
Belt 12cm - deck 8cm
and...18x38cm guns !!!


Good luck to the enemy battleship ...Renown, Hood or DoY

Huszar,

hast Du die Trefferwahrscheinlichkeit nach den Treffern auf dem jeweiligen Schiff angepaßt oder bleibt es bei den 3% ?
Gruß, TM

[Huszar]

Ja, nachdem die Rechenzentrale ausgefallen ist, sank die Trefferwahrscheinlichkeit auf 1%, bei Renown hab ich aber nichts geändert.
