View Full Version : CV-9 USS "Essex" WWII for FSX/P3D

Hi,
Not many interesting WWII carriers on the "market" (I was looking good carrier for model of AH Helldiver) so I started separated topic about my mod for the model of Collin Glendinning (from the AH SB2C Helldiver topic http://www.sim-outhouse.com/sohforums/showthread.php/105348-Aeroplaneheaven-Helldiver-Released!?p=1078184&viewfull=1#post1078184 ) done for CFS. I did conversion for P3D, solved some of problems with model in FSX/P3D, added new textures (especially deck) for two kind of USS Essex (from 1944 and 45), used another mod (of roger-wilco-66 and Hooky722) but did corrections and proper textures for aircrafts from Essex (and converted to P3D). It works as AI now also with AICarriers2 and TacPack (but model must be tacpaked for VOR). I hope You like it. Ideas are welcome but I am not a modeler so any help is welcome :- ). Model will have clear option, launch and recovery config. I will add it on SOH for sure (in the one package).

The preview 1944 version:

When you use AiCarriers you will pick if you want launch, recovery or empty. And I assume if you use the carrier in
TacPack you will do the same.

You can always use slew option from P3D or FSX or cinematographer mode in P3D for example :wavey:(Shift+F5).

Any chance of a post war / Korean war markings set? I know it's pre-SCB-27 refit, but I'd be happy with the post-war paint of either the -9 or any other of the Essex class.

Just a thought. Would be much appreciated by the Korean/50s era crowd.

thanks,

I dug that paint out and was whizzing around in it before I chopped to the SBD:encouragement:

Just waiting for YoYo to get back. One of the sound files was causing an anomaly in FSXA and not P3D so.. presuming the anomaly was caused by it displaying what should have been a texture that wasn't there.. I added a texture line to the fx file which now displays nice swirly effects behind the carrier. The effect didn't call for a texture (which was odd) but seemed to need one in FSXA. YoYo was going to test it in P3D.

Yes, I wasnt at home. It was a small problem in FSX (in P3D was ok), now looks ok I think in both sim (thx Dave).
I removed also "9" from the tower and hull as it was i real Essex. AI Carrier 2 is necessary to see all accompanying ships.

Just FYI, the YouTube video of "The Fighting Lady" is better quality than a DVD I bought a while back. Even the VHS version I got from the USS Yorktown museum store years ago was better than the DVD. I'd love to see TFL restored and reissued with the same great color and quality as "Dive Bomber".

expat
May 17th, 2017, 00:59
Saw Dive Bomber on TV not long ago and the quality was outstanding. Almost eerie watching the hi quality color movie scenes of squadrons of Grumman F3F's that looked like the film was shot this year, then you realize it was made 75 years ago!

Apologies, very off topic but along the lines quoted above:

While I absolutely agree on the warbirds being TacPack'ed, can warships also be equipped with weapons that defend and/or attack? Imagine putting the SBD and Helldiver to work dropping bombs and launching torpedoes onto the moving airfield and their supporting ships. Does the capability already exist and I am ignorant of that aspect? This would be a graphically beautiful update to CFS.

This would be a graphically beautiful update to CFS.

I think you accidentally typo-ed an answer to your question there. You can already do that in CFS2, presumably in CFS3 and in the IL-2 Sturmovik 1946 series, which lets you take off a whole formation from a carrier, not just the player a/c.

If you have tacpac, any ship in your boats folder can be added to the tacpac Carrier tab.When it's point defences activated they can a b**** to try and sink We practice all the time trying to sink them when there defenses are activated . You sometimes have to sworm them with multiple aircraft to get to them

Now that's an interesting tidbit of info I did not know......you sir, have my interest piqued. Any videos already showcasing that? Not wanting to detract from this great thread but if possible, can this topic make it's own thread if a video exists? I'll do some searching but definitely a bit more excited now. Thanks.

This concept of military operations in FSX - with its prons & cons compared to other sims - has been worked on for a while (from various people with this interest and from various different aspects) :

- Tacpack (for weapons & systems)
- FSX@War theaters (with detailed weapon/target destruction)
- Detailed FSX planes (by FSX developers)
- Enhanced FSX virtual environment (by users or developers)
- AI fighting user

This last ability (AI fighting user : vehicles, boats, statics - even planes to a lesser extend) is "about" to be offered in FSX/P3D community, thus about to conclude this concept of miliatry/combat scenario flying in FSX/P3D, for people interested in such an activity.
It's called FSCAI and will be probably part of FSC RED (or not).
More about FSCAI (C=combat) you may find here : http://www.sim-outhouse.com/sohforums/showthread.php/104404-AI-Combat-addon-(FSCaptain-1-8)

To the point of your quoted post - also myself waiting with a great interest for Yoyo's release - I had started developing an interactive combat photoreal Pacific theater based in FSX Mission System. But when I was aware of the existance of FSCAI, stopped to see & figure out how would this evolve and practically be applied.

Anyway, here is a video of fighting IJN ships in my Mission based Pacific theater, though
I expect that with FSCAI, results will be even better (and in Free Flight and Multiplayer also) :

YoYo, you may consider pre-releasing as is, so that giving the chance to someone
with knowledge about effects to give it a shot and maybe resolve this problem for
you, having it on his system. There are probably some people able of doing so here...

A few choices accurate to the period Yoyo's package:
Trainer - where I'd start:
Warwick (Wozza) Carter's SNJ variant of his T-6 trainer




Fighters:

Alpha Bleu Ciel Corsair, whilst FS9, ports over nicely to FSX.
Milton Shupe's F7F Tigercat
Phil Crowther's F4F Wildcat (https://library.avsim.net/search.php?SearchTerm=fm2&CatID=root&Go=Search)



If you lose the Corsairs and imagine it as a Korean War-to- mid 50s era ship, then you could add

Trainer:
Tim Conrad's T-28 Trojan



Fighter:
Tim Conrad's A-1 Skyraider





This is not an exhaustive list - just the ones that come to mind that are (within 10 years) accurate to that boat. I'm sure DaveB, Expat, and others will chime in with the ones I'm missing.

Yes this was a great addition P3D, I was used in the development and testing of the Milviz Corsair, and rather essential to that project!

For the ship modelers out there, Any ship pouring out black smoke from the stacks would have the engineering officer standing on the bridge undergoing a rather harsh tirade from the Captain. Blowing the stacks is done periodically but with permission! Night would be good time.

YoYo, this is an excellent package. Your attention to detail is extraordinary. I found out the hard way that when the announcement, "Clear the deck, incoming aircraft", shortly thereafter, my aircraft was swept off to the side and in some instances into the drink. That was funny. I enjoy the opportunity to share the experience of late 40's carrier practices.. Very different than modern practices. Thank you for sharing with the community..terry

Yes this was a great addition P3D, I was used in the development and testing of the Milviz Corsair, and rather essential to that project!

For the ship modelers out there, Any ship pouring out black smoke from the stacks would have the engineering officer standing on the bridge undergoing a rather harsh tirade from the Captain. Blowing the stacks is done periodically but with permission! Night would be good time.

"landlubbers" should understand what "blowing tubes" (not stacks) is. Soot builds up on the collection of heating tubes inside each boiler as fuel is burned, despite best efforts to burn fuel in the most efficient way by controlling fuel-oil mixture. If soot builds up it creates 'hot spots" on tubes which can cause a tube to rupture, which requires boiler shutdown and repair - thus losing full power capability for a considerable length of time.

A more common reason is that, even with even, light soot distribution on boiler water tubes, efficient heat transfer to the water is impaired. Boiler powered ships burn a LOT of fuel - anything to increase fuel efficiency was important. One reason you hear about "Navy showers" and "cold water showers" is that it takes fuel oil to distill salt water - if fuel got critical, these measures would help.

Blowing tubes consists of venting high pressure steam in a controlled fashion within each boiler to clean the soot off, which then goes up the boiler flues along with the normal stack gasses. It could be quite spectacular at times!

From CV-60 through CV-67, 1200 psi "D-Type" boilers were used (8 of them), using very high pressure superheated, or "dry" steam. A rupture in a boiler tube -any one of them -was a big deal to just plug, if possible, let alone repair or replace, typically a shipyard job.

These "oil burners" did not necessarily have all boilers lit off or producing propulsion steam at all times, so bringing up steam from say six of eight to increase speed created a lot of soot buildup due to the rich mixture required for fast buildup, created a lot of internal soot as well as stack smoke from combustion

"Blowing tubes" might be done running downwind between recoveries if flight ops were in progress. The Engineering Officer of the Watch would request permission from the Bridge, the Officer of the Deck would alter course to keep stack gas slightly to starboard to avoid the sulfides settling on parked aircraft. Following the ship's SOP, he would then give permission to "blow tubes". Blowing tubes was a routine, required boiler maintenance/operational procedure.

Good explanation! The thickness of the black sooty "smoke" is rather amazing. Today, or even since WWII not as a big a deal, but in the days of active and present submarine threat smoke on the horizon could be a real give away. Often coal fired merchantmen were given away by their stack effluent while otherwise over the horizon.

There's an excellent description from one of the ships that was part of the Falklands Task Force, on the way South, where a reporter was standing on deck and every now and then the (civilian... Elk, from memory?) ship's engineer would appear on deck, look up at the stack, wait a while, a puff of dark smoke would come out, he'd emit a loud expletive and disappear again. A few minutes later, lather, rinse, repeat.

Sorry, I know that's off topic, but the thread reminded me of it.
