The 1972 variants of the A-6E have advanced computing bombsights but the 1975 variants have ballistic computing. If possible can the CWDB and DB3K versions of the 1975 A-6E have advanced computing bombsights or the 1972 variants of the A-6E have ballistic computing to correct this downgrade in bombsights?

Possible database error:

Playing the Community Pack "Regulus" scenario with DB build 476, none of the American subs have Acoustic Intercept sensors.
Subs in the scenario are GUPPY IA, GUPPY IIA, and Grayback/Growler classes.

The Soviet subs in the same scenario do have Acoustic Intercept sensors (example: PL-613 Whiskey III has 1x Acoustic Intercept [MG-13 Svet])

I don't see Acoustic Intercept sensors on any of the GUPPY variants or any of the various Regulus SSG classes. The Soviet MG-13 Svet is listed in the DB as "Early 1950s Technology", so it seems likely American subs in the 1950s and 1960s would have had an equivalent sensor.

Thanks to the DB maintainers for keeping up with all of this!

Hi Thanks
anybody got any links to USN Acoustic Intercept Sensors

In doing research for a Rhodesia scenario, I've found several errors with the Rhodesian forces currently in the DB.

Find below a partial list of aircraft used by the Rhodesian Air Force. I've omitted training variants and non-combat aircraft, like the DC-8. Those with loadout issues are italicized. (I explain those issues below.) Those missing entirely (or at least missing Rhodesian versions) are bolded.

Rhodesian Combat Aircraft
Hawker Hunter FGA.9
Vampire FB.9
Vampire FB.52
Canberra B.2
Reims-Cessna FTB.337G "Lynx"
Provost Mk 52
C-47 (A Rhodesian version would be a standard C-47 with room for paratroopers, as in other countries.)
Alouette II
Alouette III (The RAF owned 6 Alouette IIs and 34 Alouette IIIs. I don't believe the Alouette II was ever used during Fireforce operations.)
AB.205

Loadout issues and loadouts for aircraft to be added are described below.

First, the Hunters. The RAF employed a unique bomb, the 450kg "Golf" Bomb. These were FAE bombs, apparently roughly as powerful as a standard 1000lb bomb. (The "Golf" Bomb is not currently in the DB. Be nice to see, but it can be approximated with 1000lb bombs.) More importantly, Rhodesian Hunters -- like most exported Hunters -- could also be equipped with Sidewinders for A2A missions, but I can't find any A2A loadout with Sidewinders for any Hunter variant.

Second, the Rhodesian Canberra B.2s currently have only a single combat loadout, with 6x 1000lb GPBs. An additional loadout should be added, replacing those GPBs with 6x Alpha Bomb Hoppers. The Alpha Bomb was actually a Rhodesian invention, and while the South African B(I).12 has a similar loadout (they adopted a modified version of the Alpha Bomb later), SA's Canberra is not appropriate for Rhodesian scenarios: the B(I).12 had external hardpoints, which allowed SA to attach 68 MM SNEB rockets; the Rhodies had no such luxury with their B.2s.

The Lynx was a fun little character. Essentially a Cessna Super Skymaster stuffed with hardpoints, the standard loadout included twin Browning .303 MGs, 37mm SNEBs, Alpha Bombs, Golf Bombs, and a frangible napalm drop tank. In a similar role before the Lynx came along was the Provost Mk.52, an armed version of the Provost trainer: these were armed with 2x 7.62mm MGs, and could take either 500lb bombs or rockets.

Finally, the Rhodesian Alouette IIIs should have several armed loadout options: their fire support was critical during the Bush Wars. RAF Alouette IIIs in the kill/command (or "K-Car") role were generally armed with an MG 151 firing out the port side, which could take either 200 or 400 HEI rounds. An alternate loadout used 4x Browning .303 MGs instead of the MG 151 (all also firing out the port side). In the gunship (or "G-Car") role, the Alouette IIIs were armed either with the 7.62 FN MAG or dual .303 MGs -- again, port side. These gunship variants also had room for 4x troopers. I'm not sure whether the Alouette IIs were ever armed or used in combat, so we can leave those be for now.

Let me know if you have any questions or need source information. All of this is info is freely available online, though corroborated in more detail by books I've read on the subject.

FYI the following US WW2 era DEs are supposed to have steam plants vs diesel plants.

DE 224 Rudderow
DE 339 J.C. Butler
DE 51 Buckley

The F-101 Voodoo has some engine discrepancies... some have a single J57-53 #1 others have 2x J57-P-55 #1.. this includes the RF-101 variants as well. The plane is supposed to have TWO engines.


Thanks!

This might contain what you’re looking for in terms of references to the acoustic intercept technologies. But as a history of ASW, it doesn’t really have technical specifications.

Broadly speaking, what differentiates acoustic intercept systems from passive sonar?

Hi Tnx this will be helpfull

Passive sonar "hears" anything, and as complement sound intercept devices detect, classifies (determine type/name of active sonar) and localizes by triangulation hostile active sonars.

Hi,

I am planning to create scenarios involving Soviet heavy naval units. However there are a number of inaccuracies on the ships so I would like to request changes. All of my requests are for units I intend to use in scenarios.

All information is from the book Stalin's Ocean-Going Fleet: Soviet Naval Strategy and Shipbuilding Programmes 1935-1953 by Jurgen Rohwer and Mikhail S. Monakov

Changes to DBID #266 BB Oktoberskaya Revolutsiya -- Soviet Union [-1991] (Naval Fleet [V-MF]), 1951, Cancelled Project

Length should be changed to 282 meters.

Standard displacement should be changed to 72950 tons.

Although I don't actually have information for it, presumably an HE shell existed for the 406mm guns of the Project 24 class battleship. I would like to request the creation of an HE salvo for the 406mm/50 Mk1 Triple Soviet mounts on the unit, but as I don't have details for the HE shell the specifications and parameters of the HE salvo may be decided by the DB manager.

The max speed should be lowered to 30 knots. The full throttle setting should become 25 knots.

Rename to BB Project 24 -- Soviet Union [-1991] (Naval Fleet [V-MF]), 2x planned

Change the year of entry into service to 1959

Changes to DBID #315 AKR Project 72 CV -- Soviet Union [-1991] (Naval Fleet [V-MF]), 1960

Length should be changed to 273 meters

Beam should be changed to 33.5 meters

Draft should be changed to 8.7 meters

Standard displacement should be changed to 30700 tons

Crew should be changed to 2300

Aircraft capacity should be changed to 62 medium aircraft in total. There is no information available for the amount of parking space on the deck and in the hangar so the DB manager may make decisions on how to divide it.

Rename to AKR Project 72 II-B CV -- Soviet Union [-1991] (Naval Fleet [V-MF]), 2x planned

If needed I can send a folder with pictures of the pages with the information.

Yes please

Here is data for the Stalingrad class battlecruisers, Kronshtadt class battlecruiser, Project 71 class carrier, and the German carrier Graf Zeppelin in Soviet service.

All information is from the book Stalin's Ocean-Going Fleet: Soviet Naval Strategy and Shipbuilding Programs 1935-1953 by Jurgen Rohwer and Mikhail S. Monakov

Crew should be changed to 1037

The armor thickness' to be changed are as follows, and should be changed to the corresponding level (light, medium, etc.) within the database.

Belt: 230 millimeters

Bulkhead: 330 millimeters

Deck: 120 millimeters

Engineering: 275 millimeters

Draft should be changed to 8.7 meters

Standard displacement should be changed to 36500 tons

The crew is actually 1710, currently it is 1712, because it is such a small difference this change is up to you.

The armor thickness' to be changed are as follows, and should be changed to the corresponding level (light, medium, etc.) within the database.

Belt: 180 millimeters

Bulkhead: 140 millimeters

Deck: 95 millimeters

Bridge: 250 millimeters

CIC: 250 millimeters

Max speed should be changed to 35.2 knots. Cruise throttle should be changed to 17 knots, full throttle should be changed to 30 knots. Fuel consumption should remain the same for all. A new engine DB entry will probably need to be made as it appears the Kronshtadt uses the same one currently and does not need to have its speed parameters changed.

Changes to DBID #310 AKR Project 71 CV -- Soviet Union [-1991] (Naval Fleet [V-MF]), 1957

Length should be changed to 199 meters

Standard displacement should be changed to 10600 tons

Crew should be changed to 580

One of the Open Parking (10x Medium Aircraft) should be removed.

Soviet Carrier Steam currently used on the unit should be replaced by 2x GTZA TV-7 Boilers & Steam Turbines, like the ones on DBID #163 KR Chapaev. The Project 71 used the same hull as the Chapayev class cruisers. The max speed for the GTZA TV-7 Boilers & Steam Turbines should be changed to 33.5 knots (this will also fix the max speed of the Chapayev in the DB, which is currently a bit low).

Rename to AKR Project 71A CV -- Soviet Union [-1991] (Naval Fleet [V-MF]), 4x planned

Change year of entry into service to 1960

Changes to DBID #503 AKR Orlitsa (Ex Graf Zeppilin) -- Soviet Union [-1991] (Naval Fleet [V-MF]), 1954, Cancelled Project

Draft should be changed to 8.5 meters

Standard displacement should be changed to 33550 tons

Change year of entry into service to 1956

If needed I can provide a folder with pictures of the pages with the information.

I remember someone requesting the Project 85 class carrier awhile back, I don't know how far along the work on adding it to the DB is but if information is needed on it I have that too.

Also, there are some missing units- the Pr. 23NU Sovetsky Soyuz class battleship and the Project 66 class light cruiser. I am planning to request the former but I do not need the latter for any scenarios I plan to make, but for the sake of the completion of the addition of the cancelled Soviet heavy ships I can provide data for it if needed.

Requesting the following US Sub Classes be added to the Cold War Database 1946-1979 (CMANO and CMO) or corrections.

Suggested Corrections:

#463 SSRN 586 Triton (Navy) 1959-1961 - I think this is representing the re-classification of the Triton to an SSN in 1961. If so it should read:

SSN 586 Triton (Navy) 1961-1969

----------------------
#51 SS 574 Grayback (Navy) 1964-1975 - Grayback was re-classed from SSG to and APSS in 1968. She was decommissioned temporarily in 1964 while work was performed converting from the original SSG configuration to her final APSS layout. She decommissioned in 1984. I think this entry should read:

APSS 574 Grayback (Navy) 1968-1975

#324 SS 574 Grayback (Navy) 1975-1976 - See above for her classification. Multiple internet and book personal book resources indicate Grayback decommissioned in 1984. I think it should read:

APSS 574 Grayback (Navy) 1975

---------------------
#281 SSN 671 Narwahl (Navy) 1967-1969 - Multiple internet resources and personal book resources indicate Narwhal commissioned in 1969. I think this entry should be deleted.

--------------------
#324 SS 574 Halibut (Navy) 1975 - Multiple internet and personal book resources indicate she decommissioned in 1976 (not 1975). I think it should read:

SS 574 Halibut (Navy) 1976

---------------------
#222 SSN 594 Permit (Navy) 1962-1965 - This class was originally the SSN 593 Thresher (1961-1963) class. The Thresher was lost at sea in 1963 off the Boston coast and subsequently began to commonly be referred to as the Permit Class. I'd suggest either adding a specific SSN 593 Thresher entry OR simply changing the existing #222 entry to:

SSN 594 Permit (Navy) 1961-1965

---------------------
#506 SSN 685 Glenard P. Lipscomb (Navy) 1978 - Multiple internet and book resources indicated she commissioned in 1974. I think additional entries may be required beginning from 1974.



Suggested Additions:

SSN 597 Tullibee (1960-1988)

ORIGINAL: Ancalagon451

Found an errata in the Yak-9 Frank fuel consumption table, as you can see in the image the burned fuel while at max power if by far the lowest of all. Giving it an endurance of as many as 8! hours at max speed.

Ancalagon

It's not just the Yak-9, seems that many prop-driven A/C have this issue. I'm seeing it on AD Skyraider, B-29, B-36, etc. I'm wondering if the mil consumption was intended to be kg/s instead of per minute?
