Need some help from the 'older hands'!

Going through the old UK reports when Gravina was player when looking to see if any of the X-1 class submarines were built I noticed Gravina built two new aircraft tenders, HMS Pegass ans HMS Maidstone in 1927.
No stats made their way to the encylopedia but I wondered if any of the older players who can remember five years ago can ever recall any stats or where they might be posted.

If none exist would anyone have objections if I reverese-engineered them from the 1927 report tonnages paid to make a new SS report?

Comment by RLBH about the Maidstone. I presume they exist based on the presence of the reports, though.

I can find no Springsharps in a web-search of the forum, so I suspect they were never posted.

So long as the displacements match that outlined in the sim reports, I'd accept that, yes.

Ye Gads it gets worse.

The following are 'missing' ships from 1927
HMS Pegasus 12,000 ton Seaplane Carrier/Tender

HMS Maidstone
HMS Forth
9,000 ton seaplane carrier/tenders

HMS Echodale
HMS Ennerdale
15000t Fleet oilers

HMS Oakol
HMS Teakol
HMS Cedarol
10,500 ton fleet oilers

None of these have been listed but look to have been built.

Then I found Alt Naval also did a four qaurter UK report for 1927 as well which mentions none of these ships and seems very different!

I'd like to SS report the tenders at least and add all of these to my existing fleet numbers and removing the oldest to make sure the total tallys are the same.

None of the X-es were built under Gravina. He indicated that in the 1926 report. No indications in any of Gravina's posts regarding sims of the Pegasus and Maidstone/Forth. Only weights are given.

RLBH said: "the information I have doesn't suggest that they exist." but 1926/1927 reports by Gravina clearly indicate that they were built and completed in those two years.

Can't edit the post to add...

Oilers seem to have started in 1927 but it looks like there is a gap between Gravina's last report and RLBH's first report (could be wrong; haven't looked at it properly) so it seems obvious that they were completed before RLBH's first report.

If the ships are in the sim reports, but no sim is present in the encyclopedia nor can be found elsewhere, then I have no problem with simming the ships anew.

That explains the terrible state of affairs of the British support fleet. So I agree, if the tonnage was paid feel free to add to encyclopedia. I guess you save some tonnage by don't doing some refits to the older ships. ;)

Here are some proposed SS reports. I've renamed Maidstone and Forth since I've used them for other tenders.
Given the large displacements I see the Pegasus to be like the OTL Curtis class, mainly a tender. The smaller two ships are more akin to scouts along OTL Japanese lines with the ability to defend themsleves against enemy DDs and CLs they might encounter.
The light tonnage is identical to that posted in the reports.

I need more help from the old hands as I've found more inconsistencies from Gravina's days as player.

1. The 70 DE23, DE24 and DE25 classes. Are they all of Defiant Class specs?
All of these now are reaching scrapping age so its not vital but some could be rebuilt into sloops. Even RLBH was trying to work out what was going on!
1922 DEs

2. The four Hector Class cruisers (HMS Hector, HMS Priam, HMS Aeneas, HMS Paris) were built and are on reports and have SS reports on them but they don't appear in the encloypedia. Where did they go?
Hector

3. The eight Powys Class DLs, the same as the Hectors, were definately built and have SS reports but again where are they?
Powys

4. HMS York and Exeter , two unknown ships to me but these have been built but no final decision made on the specs Gravina posted. Now there has always been an odd number of CAs which never matched all the names I had for RLBH's ships so these two missing ships have been counted. I'd like to have these and cut two of the Kents I have (but I was never sure all of them were Kents).
York

These have all been paid for so should exist somewhere. Somehow the encloypedias and OOB tallies must be out or they have been counted but not present?

If they were paid for they should be included in the encyclopedia. But that is just my opinion.

Agreed, if the costs are payed, the ships are built so they should be included in the encyclopedia.

Wednesday, April 20th 2011, 10:29pm

My proposed solution is thus;

With the seventy DEs, due to their age, it is now assumed that the 20 DE23 and 20 DE24 are now decommissioned (awating scrap), that leaves some 30 DE25 the last of which would be decommissioned by 1942-43. Some may end up in the Egyptian and Iraqi navies. Now of course I won't be swamping the market with 70 used DEs but most will end up as scrap but some will reach the export market.

The four Hector would be assumed to have been transferred to the RCN alongside the Diana Class due to their common 5.5in guns which the RN doesn't use.

The eight Powys would remain in RN service and all need refits/ rebuilds about now.


The heavy cruisers pose a bigger problem. When I took over as UK player I had 12 heavy cruiser based on RLBH's reports. RLBH was working to Alt Naval's 1927 and 1928 reports so that force was 4 Howe/ Hawke, 4 Anson and 4 Kent.
Now to complicate Gravina had already posted a full set of 1927 reports in which York and Exeter were built. Alt Naval came along when Gravina left and did a second set of 1927 reports where three Hawke Class took the place of the two Yorks.

So what happened to the Yorks? Alt Naval seems to have discarded them and they turned into the bigger Hawke (in the enclopedia as the Howe Class).
I leave it to the mods to decide the fate of the York Class on the basis of Gravina's final reports.

I'll have to review the sim reports themselves to be certain, but my gut feeling is to prefer Gravina's reports over AltNaval's: having reviewed the Greek reports extensively before Sachmle took over, I found a lot of mistakes there.

Aieee! My sanity!

I made the fatal mistake of digging up the dregs of past UK reports, and found that there are duplicated reports for 1925 to 1927 (ish), which don't match. I'm treating those produced by Alt Naval as "canon", since I wasn't aware of the alternate option until about five minutes ago.

However, Gravina's reports make extensive reference to the DE22 and DE23 classes - which, at least, I should have - and also DE24, DE25 and DE26 classes, which I assume are lost to the duplicate reports. That accounts for the "40 to 70" figure for DEs in the order of battle.

However, I haven't the remotest notion what these ships actually are, despite searching the forums. I can only assume they are some sort of derivative of the so-called "Defiant" torpedo boats, unless someone can enlighten me...


It also appears I may be owed some factories...

Does this sound fair?

And a quick look (I haven't crunched any numbers here or anything) seems to imply that the F and G class CLs replaced the Hectors during the three-year overlap. Likewise, it seems the Drake class replaced the Kent class (I remember talk about how whomever was running the RN at some point didn't want his CAs to be confused with OTL counties, and thus didn't use county names), and likewise the Hawke class replaced the York/Exeter, with Alt-Naval making it a larger class in the process.

It would appear to me that that's not the course past British players elected to go, as Canada only had ten when it became a player country. In any case, we're trying to determine correct ship totals, not redistribute Great Britain's factories. What's done is done, so far as I'm concerned.

I'm leaving things alone, its too tangled to untangle it all without causing wider complications for a number of ship classes.

I've not lost anything really but at least the DE question is finally cleared u in my mind even if most of those ships have now moved on to pastures new.

No such thing as a free lunch; Any factories owed to Canada would be deducted from what the UK has, just like when Canada was started.

I don't even know if the Crown has built 5 factories between then and when I started playing, nor really expect Hood to follow up on it, I just found it interesting.

[size=1]And even a long shot of getting a few more factories doesn't hurt. :P[/size]
