I'm not sure how official this was but in 1919 a Dutch naval officer established that the size of the Dutch navy for defence of the Dutch East Indies to be:
1922-1924 consisting of 1 division battleships consisting of 4-30,000 ton super dreadnoughts
1 flotilla of 8 destroyers
1 division cruisers consisting of 1-28.000 ton battle cruiser with a speed of 30 kts
3-7,000 ton protected cruisers with a speed of 32 knots
3-1,500 ton scout cruisers with a speed of 35 knots
3 flotilla’s submarines each of 1 torpedo cruiser, 3 torpedo boats and 10 submarines.
He suspected that an enemy force of 8 super dreadnoughts supported by cruisers and so on would gain the supremacy in the Java Sea. Further more was it possible if the Dutch finances were booming again within 8-10 years the Royal Netherlands Navy even could number 8 super dreadnoughts and 8 super dreadnought cruisers or battle cruisers. His main opinion was that if the Netherlands were not able to maintain a fleet able to have the supremacy in the archipelago an absolute strong army was necessary to hold at least Java and Sumatra in Dutch hands when the navy failed to stop the enemy invasion.
One-time costs:
4 super dreadnoughts (160 million Guilders)
1 battle cruiser (40 million)
3 protected cruisers (30 million)
3 scout cruisers (12 million)
3 torpedo cruisers (9 million)
8 destroyers (12 million)
9 torpedo boats (9 million)
30 submarines (45 million)
sub total 317 million Dutch Guilders.
Further more 35 million for naval base, air force support pints
sub total 352 million minus already available material ad 80 million sub total 272 million with 8 million for unsuspected costs was in total 280 million Dutch guilders at once needed for obtaining a powerful fleet.
Annual costs for maintenance of above mentioned fleet
4 battleships each 2.75=11 million
1 battle cruiser 2.7 million
3 protected cruisers each 0.35=1.05 million
3 scout and 3 torpedo cruiser each 0.3=1.8 million
8 destroyers each 0.15=1.20 million
9 torpedo boats each 0.08=720,000
30 submarines each 0.08=2.40 million
sub total 20,87 million Dutch guilders to which around 4 million were to be added for arsenal, department, administration, education/training totally 24.87 million Dutch guilders.
