upgrading navel units

[unmerged(40280)]

is there any way in 1.06 to get your navel unit to upgrade to the next model?
I'm playing as England and I start out with a large navy but I have to scrap then becouse their the same model but with the upgrades.

Ships can not be upgraded to the next model in the same way as tankdivisions and aircraftunits, the upgrade option will improve things like radar, firecontrol etc. but the hull stays the same. For the time and effort it takes to enlarge the displacement/ the guns or th powerplants, you may just as well build a new ship and this why it is modelled this way in the game. AFAIK only the Italians and the Japanese tried it with some of their BB's and BC's and the endresult was still not satisfactory.

If I play a country with naval aspirations I put the level 1 dd's on escortduty but I keep the other ships around. Their level determines if I use them in my battlefleets or in ASW/ TransportFleets. Especially as Britain you have so many commitmwnts and so little IC that you can't afford to disband all of your units.

Note that many of the changes, especially when it comes to ASW are not inmediately visible, because you have to select the individual unitstats to see things like subdetection and attack, but it is in these areas where the biggest benefits are. I also research several levels, usually upto basic centimetric, before I upgrade my ships, to save money and micromanagement.

Well, all battleships and battlecruisers were reconstructed to some extent in the interwar years because new capital ships were not allowed to be built due to the Washington Treaty, but most limited the refits to increasing deck armor, adding torpedo bulges and increasing gun elevation.

The Italians and Japanese also reboilered the Cavour, Doria and Kongo classes to increase speed and the Italians even rebored the main armament to a larger diameter and thus a larger, heavier shell. I might add the British to the list as well, the Renown class was very much rebuilt with additional belt and deck armor but as you said, no amount of rebuilding on any of these old ships would make them even close to as effective as a newly built battleship.

No amount of refitting would allow an old class to be as effective as a newly built warship. The only way this could be achieved would be to strip a ship down to the keel and rebuild her and any economist would likely say breaking up a ship to rebuild it is likely twice as costly as just building a new ship. The Washington Treaty forced nations to refit and rebuild their capital ships but odds are it would have been just as easy to simply build a new warship and break up the old one but new ships were not allowed per the treaty so the old ships soldiered on. Not until nations like Japan said they would not renew the treaty would Britain, France and the United States build new capital ships (though the Dunkerque class was allowed to be built to replace the France which floundered in 1922 and Ocean (ex-Jean Bart) which was to be disarmed).

If you are playing the 1936 scenario then there is a considerable benefit from upgrading ships as long as there is a good selection of tech improvements available. If I play a ntion with a large navy I try to get an upgrade tech (any upgrade tech) as soon as possible. At this point you can send all your ships for upgrade. They now stop using supplies and the upgrade cost is likely to be less than the years of supply till they are needed. As long as you leave them undeployed they don't need any supplies. The next point, and this is important, is that they receive all the upgrade technologies that you discover up to when you deploy them. This means that you can send them for upgrade before developing the technoligies. You may not feel that the upgraded vessels are as good as new ones but they are a lot cheaper and the upgrades can make them a lot better - for example there are technologies that will give a cruiser +7 AA and +14 Naval attack, although some of them don't need upgrades.
