It didn't end with commissioning. After commissioning you had speed trails, then drydock. Then shakedown cruise, then drydock again, then often a short training/gunnery period..then sometimes another drydock after that.
In peacetime it could take up to a year before a commissioned ship finally joined it's division. Wartime version in most navies had it down to around 6-8 months.
In general yes, but
occasionally ships were send into battle
immediately after commissioning (HMS
Prince of Wales hunting the
Bismarck,
Taiho in the Battle of the Philippines Sea). There were probably more similar cases). A few ships (like the HNLMS
Willem van der Zaan in 39 scenario) appear as part of the fleet although they were commissioned
later in that month.
Your comment makes a good case to leave all the DD and SS that are scheduled to be finished a couple of months later than IRL as they are.
But for
capital ships, delays by
several years can't be explained by
trials, shakedown etc.
The Farraguts, while made in the early thirties were built on a design from the early 1920's that they sat on for over a decade and were simply an improved version the Clemsons. It was nice when Paradox used the Clemson hull and gave the Farraguts a 3+ buff all around and made it a separate class. That was about right for what it was. From there on though, once DD construction restarted in the 1930's, the new classes were designed differently. they were different ships. They weren't even flush deckers. Porter, Mahan, Gridley, Bagley, Somers, Benham. The question becomes, what about Sims? Sims is is kinda hwre the type took leap forward, but remained a the same basic type. But it was actually more related to the Benson the to the previous ships.
The Farraguts had a different hull form (transom stern, forecastle), different weapons, different weapon layout, and more advanced machinery (as one would hope). They were in many ways closer to the British V/Ws than they were the Clemsons (they had a similar weapon layout and more similar hull form). I'd need to hit the books to be sure, but I'd wager the Farragut's had more in common with the Bensons than the Clemsons (I'm quite sure they do in hull form, and 100% confident they do in armament, but as I'm fairly sure the Bensons were after the revolution in US DD machinery so their machinery may have more in common with the Clemsons).
Our group has overwhelimingly shares the opinon
@Axe99 expressed. It's based on multiple sources.
I. Opinon of Rear Admiral
Emory S. Land according to
Wikipedia:
- The
Farragut class was 3.3 knots faster.
- The class had double the
GM height (resulting in greater stability).
- They had 25% more armament—5 main guns rather than 4—and about 35% greater firepower, mounting
5 in (127.0 mm)/38 caliber guns (Mark 12) as opposed to the
4 in (102 mm)/50 caliber gun (Mark 9) mounted on most previous destroyers.
- All 8 torpedo tubes were on the preferred centerline position.
- The guns were fed by power hoist from the magazines.
- Being
high-freeboard vessels, sea-keeping was much improved over the flush deckers that preceded it.
- The radius of action increased by 450 nautical miles (830 km; 520 mi).
- This had all been accomplished on a displacement rise of only 22%.

While some of these points are referring to armament or engine, many of them are represented by the
Tier II hull.
II.
Destroyer History Foundation groups the
1930s classes (From Farragut to Sims) together drawing a
clear line between them and the
Flush deckers (in-game
Clemson class).
III. According to Navypedia the Farragut design process began in 1928 and was finished in March 1931.
They were
NOT a WWI design. (Similar to the British
interwar standard classes and derivate classes in other navies).
Currently, all these classes are
spread across T1 and T2 hulls. We decided that making them
all tier II should reflect that they were generally
newer and more advanced than
actual WW1 ships. We think there should be an In-game distinction between their hulls least
min-maxing players upgrade all their old WW1 DD to
Sims class. (or play with
Sims-class as a
upgunned WW1 hull)
Some newer classes of
small DD, DE, large TB and MM build in the 20s, 30s and 40s should also be
Tier I but this
certainly doesn’t include the
Farragut to
Sims classes. In the late 30s they were up-to date ships.
The Bensons, while still a prewar ships and technically a treaty 15 tonner,was actually pushing that line and were 16 tons. they were significantly improved from the previous ships. Benson's are strange, because they have two official sub classes (Benson and Gleaves), and some break it into even 4 subclasses (Benson, Gleaves, Livermore and Bristol) There were differences, but nothing significant, especially in game terms.
So you have the T1 Clemsons, the 36 T2 Sims, 40 T3 Fletcher, and the 44 T4 Allen M Sumner. Thats doesn't really fit well. The T3 would be the Benson's, because you can easily start having them drop from the docks in 41 before the war even starts...which was just when the Benson's starting dropping in real life. Fletcher's didnt make it to the front line until very late in 42..but they weren't Benson's They returned to the flush deck design and so were much larger, faster and longer range.
We have actually argued internally if the
Benson &
Gleaves class should be
downgraded from
tier III to
tier II but decided to propose this.
The reasons why:
- We
unanimously agreed that the
Fletcher class (
not exisitng in the 39 scenario but it's relevant for anyone who wants to build a
historical US Navy for roleplay) is an obvious step upward and should have a hull tier above the Benson & Gleaves class. If they are T3,
Fletcher would
have to be T4.
- This would mean that an US player would need to rush
1944 light ship hull to get it
in late 1941. If they
start in 1936, they would need to rush the
1940 hull for the
Benson class (laid down in 1938) as well.
-
AI-conrolled US would
almost certainly not rush these techs.
- As the
Japanese DD (
Fubuki and later classes) would be
Tier II (a minority suggested improving them to level III, but the community is also agains this (see
@Paul.Ketcham 's post expalining this on page 10, he got
multiple agree and no objections.) If
Fletcher is tier IV, it would outclass the Japanese too much.
-
newer hulls consume more ressources and NIC, T3
Bensom and T4
Fletcher would make it harder for the US to produce the
historical number of DD.
- We agreed that
Tier IV hulls should be reserved for ships designed from
actual war experience. The
Fletcher class was still a pre-war design.
Here are the arguments from the minority who suggested leaving Benson & Gleaves at Tier III
- This would align hull tier with
destroyer generations according to John Reilly
image from
destroyerhistory.org
-
Fletcher class is more similar to the
Summer and
Gearing classes than to the
Bensom (and subclasses). The line should be drawn between
Fletcher (Level IV) and
Benson (Level III) class.
- USA has
more research slots than anyone else, they
can rush techs.
-
Historical US AI can be programmed to rush hulls.
-
Fletcher class
remained in service untile the
70s in the US Navy and the
90s in other navies.
-
Fletcher class
didn't exist in 39 scenario and can therefore be
ignored (
singular opinion, most of us
care about it.)
IMPORTANT QUESTION for the community:
Should we
revert the suggestion to
downgrade Bensom &
Gleaves class to
Tier II?
This would
necessarily imply that an accurate
Fletcher class should have a
Tier IV hull.
Porter and Somers were designed as Destroyer Leaders (Porters were actually Flotilla Leaders, but Omaha's were also supposed to the Porters successor until the Navy Brass pulled a Bradley on them and bloated them up to cruisers). As such they needed more room for the Flag, hence their longer hulls. Otherwise no real difference over the other standard classes built alongside them. Porter is kinda on the border. It was also designed alongside the Farraguts and as such are just longer versions of it. The Mahan was the first true post war Treaty era designed ships that the starts the 15 tonner line (despite several classes actually going well over that).
They had more guns (8 vs 4 or 5 on other DD classes). Similar to the
Mogador and Navigatori classes. otherwise they were similar to them. We proposed to add a second light battery module and upgrade the torpedo module to reflect this.
(Somewhat off-topic, having effectively
only two hull tiers for
light ship hulls in the 1936 scenario makes things
more difficult, having either an intermediate stage like
@balmung60
suggested or a
Destroyer leader hull type for
DL and Scouts would help to
represent the differences better.)
South Dakota's weren't significantly different then the proceeding North Carolina class. Skimped a bit on the armor and shortened the hull for more speed (something like a whole 3 knots..oooh), and a larger castle to act as Flag (eliminating a couple of 5' DP's), but otherwise a very similar ship. Both classes were a compromise between the Fast Battleship design of the Iowa's and the slow but heavily armored "Shotgun to the face" bruisers that were the Colorado's.
We think
South Dakota should have
Tier III armor. ( although their
torpedo protection turned out to be
worse than on the
North Carolina class). As the US lack that tech in 1939 and the ships were lais down a few months ago, we thint it's resonable to leave them out, but we are open for suggestions from the community. (The difference in AA seems
negligible)
Tambor's were significant improvement on the preceding Porpoise/Salmon/Sargo classes (which were all pretty much the same, and frankly were more subclasses of the Porpoise. Nothing signifignat enough that would matter in the game).
Salmon and
Sargo classes had
two more aft torpedo tubes and carried
24 torpedos. (
Porpoise had 16). We concluded that the in-game difference (
1xTier I torpedos on
Porpoise,
2x Tier II on
Salmon) seems right to reflect this, but would like to know what the community thinks.
Tambor had
10 tubes, but still carried
24 torpedos. Should we perhaps keep the current
Salmon design for them and propose to
downgrade one of the torpedo modules on
Salmon class to
Tier I?
But then you have the Ranger. Man that ship triggers my OCD so bad. Lexington's are T1's but the Ranger is a T2? Really? Sure the Lexington's are older and built on converted hulls, but the Ranger was such a small ship, so slow and a smaller air group it was restricted from the Pacific Fleet. So much that Nimitz would rather engage the entire Japanese navy in '42 with one CV in a wheel chair in a 6 on 1 fight then bring over the Ranger. Why the hell is that a T2 ship?
We
agree with you, but unfortunately the
tier I engine is the slowest the USS
Ranger can have and she's
still too fast. There is just no way to
make her slower (29 knots IRL).
Her
overall wing size was
slightly smaller than the
Lexington and
Yorktown classes(both have far too small wings in the game) The problem was that
until the 1941 refit she was
unable to carry
Torpedo bombers. As in the game
any carrier plane can be used on
any CV, this
can't be depicted without a
larger overhaul.
It all comes down to what is it reasonable of the devs to expect from us as players. Do we get all we need on day one or given that dockyards cost build slots would that basically lock in what you are going to have to do too much. And yes we need to take the snowball effect into account.
Here's my general thinking based on current gameplay as I've adapted the past couple of months. (
opens the secret cupboard takes out Jackie Fisher's devious ship building maximisation cap and puts it on)
If I roughly double my shipbuilding capacity as the UK from 19 to 40 shipyards as a priority, (I could build more but the Army need some love too) and hit every focus I can that will give me naval bonuses (and radar) down to Expand the Shipyards (
With Battleship Focus of course, as I am having my Vanguard Focus no matter what else may happen ![Big Grin :D :D](data:image/gif;base64,R0lGODlhAQABAIAAAAAAAP///yH5BAEAAAAALAAAAAABAAEAAAIBRAA7)
) and I use my XP to create intermediate stage designs for my QE refits and KGVs that are just below the 10000 pt Treaty limit and then treat building large ships as a two stage process from that point on.

Intermediate Design in the QE Refit program
View attachment 563812
Stage II Rearmament of the QE Class once the escalator clause is in effect
Then I can take three further steps to get me where I want to be. I can use my industrial focus bonuses (2x100%) to get concentrated or dispersed to IV by early 39 giving a 40% increase in output. I can also have a focus holiday at this point and put my focus on increasing shipbuilding, and I can also when free PP is available switch, perhaps counter intuitively to free trade (a way to maximise this for the UK, is to go free trade and take steel from the Colonies and Dominions, whilst you build infra in the steel heavy provinces) for an extra 5% on top. So my yards in early 39 once the Escalator clause is activated become absolute hives of activity.
Also as productivity increases I can move shipyards to other projects and allow the refits to coast along on 2 or 3 yards as long as they finish by August or not long after.
Doing this I am able to lay down the KGVs in 37/38 2nd refitting for the QEs in 39, 1st Refit for pair of big gunned Oil Tankers in '39, 1st Refit on Hood in '39 and just around when the war start refits to put Radar on the R's and BC R's as time and capability allows.
View attachment 563801
Nelson and Rodney's usual first Refit, sometimes Radar III & AA III are available sometimes not, making me have to juggle points a little.
The KGVs will exit build in late '39-late '40 depending on how many yards I put on them and then need another three or four months on their first refit to properly arm them. And I will have Ark Royal complete with Illustrious either built or about to exit build.
As the final run in to the war starting begins I am faced with the same sort of choices that Admiralty DNC and the Government did, do I build Lion and her Sisters or do I start mass production of T1 & T3 destroyers and T3 cruisers, and throw in carriers (often my old CAs will get converted at this point). I may start Lion & Co with a couple of yards a piece and then play it by ear depending on my needs vs submarines.
It's a little harder work than perhaps it ought to be, and I have to compromise on getting the army fully equipped to thrash Gerry & Co but I seem to come out about where I ought to as long as I focus on the problems at hand.
Great info.
But is this really that unrealistic?
Before
WW1 British shipyards were
building multiple BB every year, wouldn't they be able to do so
again in the late 30s with the
political will and funding?
