Hello! good to see I am not the only one who thinks the Dutch 1947 A and B class ships are amazing ships
These drawings are not bad at all, and on first glance they look like working designs. You just have the tiny bit of bad luck that I have researched the 1947 destroyers well and based on that I found some issues....... and I hope you won't take them as dishaertening, as the good work you have so far makes it worth my time to give these comments to improve them, or even to keep an eye on these issues in future designs
You probably have found it already, but for reference, here is the thread where I commented on the design and development of the Holland class
First of all though, looks to me like you indeed redrew everything but the propellers and the sonar dome (and of course the other parts). These do count as parts, so indeed require no credits. Just a small word of caution: propellers are matched to the ship and the propulsion system, and these have smaller hulls and I suspect not the same powerplant as the Holland class, it can sometimes be a better choice to take the propellers of something more closely matching the size and propulsion plant of your ship then of the ship you started out with. In this case, that might be the Royal Navy Type 12 for example, I suspect. Does it really matter in shipbucket scale? not really in this case, but sometimes........
Anyways, my comments:
- By the single tall funnel I suspect you have roughly half a Holland plant of 45000 shp. (Either that or half a Friesland plant of 60000 shp) Depending on the exact arrangement, that would mean this ship would go about 25-26 knots in my estimation. IIRC, immidiately postwar, ASW frigates were the fast frigates so they could catch submarines that went close to 30 knots. If this is an ASW frigate primarely, is it fast enough?
- Speaking of the powerplant, I think you are missing the air intakes for the boilers. This is next to the forward funnel on the back end of the fore superstructure on the forward engine room of the 1947's and next to the aft funnel for the aft engine room.
- The Holland class destroyers are known to be extremely tight ships, evidenced by the amount of stuff they DIDN'T get over their design and development. When comparing the Friesland with the Holland, both starting out as the same design but with a slightly different hull because of different engines, the Friesland got almost everything the initial design had, while the Holland lost the Lichtraketwerper, 5 of the 6 40mm guns, the primary fire control system (leaving 2 directors on board of which the Friesland got 4 as secondary directors) and her main air search radar was dropped to the lowest acceptable level. Knowing this, we have to look at your design.....
1. You have half the powerplant of the Holland class
2. You have a smaller hull then the Holland class
3. You have the radars higher up then the Holland class
4. You have 1 40mm more then the Holland class
5. You have 1 ASW mortar less then the Holland class
6. You have the same FCS as the Holland class
7. You have torpedo tubes where the Holland has none
8. You have the same 120mm armament as the Holland class
It looks like you have more stuff, higher up, with less bouyancy, stability and weight down below to support it. In other words: somewhat unlikely that it would work. There are solutions though! Dropping the height of the radars a tad, removing the torpedo tubes, removing one of the main gun turrets, increasing hull size (Which might actually increase speed, believe it or not
) or a combination of these all work towards resolving this issue.
- Tiny issue, but the sonar directly under the gun is an issue. The sonar has equipment on top of it (the dome is also retractable into the hull, the space it takes in the hull is on the part on the Dutch parts sheet here: http://18.104.22.168/wiki/index.php/Fi ... _sheet.png
) while the gun also has a lot of deck penetration, with the magazine and ready use ammo under the waterline. There is space though to move it forwards in your design.
- I would really recommend having a blast shield around your ASW launcher.
- Those liferafts are a bit too modern for 1959, they would not come into use until the late 70's at the earliest.
- Do note that the Hollands were quite cramped for her crews. While removing half the engine plant will ease that up somewhat, making the ship smaller might offset that again. You also reduced the size of the deckhouses on the stern by quite a bit, so that further reduces space for the crew and everything a crew needs. All weapons and radars you have on board take as much or more crew then what the real life Holland got so you are definitely having a cramped crew, which will make these ships not that popular in service.
- Speaking of all the systems, do note that you have 95% (more or less) of the systems the Holland class had, a larger amount of separate systems, with less room in the ships structure to put their affiliated equipment. This will probably make these ships almost as expensive to build and operate as the Hollands, even if they have half the powerplant (The hollands often sailed with one of their boiler rooms sealed to reduce crew and maintenance in peacetime, an option you wouldn't really have). I would really recommend cutting back on that to reduce cost. Options would be dropping the torpedo tubes (not really useful for ASW), dropping the aft turret (making them less AA capable mostly), dropping the air search radar (making them unable to perform radar picket duty for aircraft)
- Adding to the above point, note that you have a ship that is more then 90% of the cost of an Holland class in my estimation but with far less of the survivability features, such as the split powerplant, secondary conning position etc. I would really recommend reducing the armament of these a bit and it could certainly work though!
Lastly, I want to add this http://shipbucket.com/drawings/3410
, showing you the feasibility of the idea. This was not my best drawing ever (and it was a long time ago) but this ship is an proposal for an ship that was friesland derived but with an much lighter armament (3 single 40mm, fixed ASW torpedo tubes, 1 quadrupple ASW mortar, dual 120mm) designed for export.
Keep going, and looking forward to more of your work (or updates of this one)!
