Ska vi fortsätta, 1920-25?

bUDGET FÖRSLAG, FORTSATT 6,5MILJ MHT freden och inflationen tar ut varandra, kanske någon minskning i nästa "femårsplan" pga fb25.

[Stofilen]

Japp, kör hårt jag är/har varit lite upptagen men jag kommer nog ifatt på semestern! Jag föreslår £ 6.6 milioner vilket motsvarar £ 2.5 milioner i 1910års penningvärde se min tidigare post. Sedan blir det givetvis en minskning 1925-30

//Stofilen

[Psilander]

Hur gär vi med Washington fördraget?, 10000ton och max 20,3 eller 21cm kanoner för kryssare och ubåtar, 35000t för slagskepp och 16"?

[Stofilen]

Japp, det tycker jag! Jag tror dock inte att det påverkar Sverige så mycket, eller tänkte ni bygga större än 35 000 ton

//Stofilen

[Psilander]

tänkte framförallt på kryssar frågan

[steben]

Washington gäller inte Sverige..Jag tror inte vårt ministormaktsverige har en såå stor flotta. Jag tror nog vi med gott samvete kan ignorera det. Sägs för övrigt om ett max.djupgående, någon form av gemensam kravspec.?

[Psilander]

´Röstar för sju (7)meter, för satt vara praktiskt andvändbara i skärgården, vad är maxdjupet för att kunna nyttja Öresund?, vilket torde vara mer gränssättande, längd 180m som Göta Lejon.

[steben]

Bismarck kom ju igenom så det är nog ingen större brist på djup i Flintrännan, åtminstone 8-9 meter utan problem. 7 m låter rimligt, sägs om 195 meter som längdbegränsning, 200 meter dockor säg.

[Psilander]

De flesta större fartyg går ju genom bälten, så också Bismarck

Dock begränsing i längd med vad som praktiskt rimligt ligger nånstans runt 150m, GL och TK var ju i längsta laget för kunna gå i skärgården, taktiskt

[steben]

7 meter är max för öresund, kollade upp det med sjöfartsverket. Vadhän denna besatthet med skärgården, dom skall väl inte möta fi först i skärgården och bränna runt med pansarskepp och kryssare i 30 knop inomskärs inte. Skärgården är en bra bas och övningsområde inget stridsområde. Det tar ju KA hand om.

[Psilander]

Genom att nyttja skärgården för förflyttningar får man ett stort skydd mot upptäckt, ubåtar och minor. Därför vill jag att fartygen skall kunna förflytta sig inomskärs.

[steben]

Ok, visst

[Psilander]

Har skapat mig en liten fregatt för ubj (som våra Snapphanen båtar) fast lite större.
