Pu-lease... You do a far better job than I do when it comes to research!

 

Still: Here's what I know of off-hand for Consolidated-Vultee:

Spoiler

Haven't looked too far into the company yet, so I'm looking forward to what you can pull out. One thing I do note is the XP-68, as it was reportedly based on the XP-54, it is sometimes portrayed in the same form, but the wind-tunnel mock-up suggest it to be more conventional in layout. This is in error, as this is the Republic XP-69 instead. The XP-68 was merely an engine swap - despite receiving a new military designation, no more seems to exist than that.

Okay so here is the general strategy:

-- account for all Consolidated, Vultee, Convair aircraft

-- chronological placement based on prototype first flight dates in relation to those aircraft already in-game

 

With that framework in place, then:

-- read narrative from many sources to account for designer, design team, design trends, milestones, relation to other aircraft

-- account for engines/armament in detail

-- repeat all of the above several times, gathering more sources as needed

 

That's basically it.  I have two concerns:

-- scope -- it would be appropriate (necessary, even) to consider other attack aircraft (Douglas, Northrop, etc.) and to read their narratives as well, but doing that is beyond the scope of this project ... for at least the next 9-12 months.

-- time -- I don't have much of it these days.

 

 

Updates to this thread will be most likely be gradual and unannounced.

Bell X-5 (06/1951) -- based on captured Messerschmitt P.1101.

Touched on both of these in my thread - the Skyray is 'potentially viable' when considering the very first prototypes and the intended J40 flop of an engine. But this would require guestimation on figures and unhistoric modules to "nerf" the plane - and there are other, much more viable Douglas aircraft.

The X-5 was considered for a fighter conversion that would compete with the F-86 Saber, but anything beyond that fact, (and a single image with stenciled guns,) is conjecture. It's not impossible for it to head the Bell line, but it is a definite "paper project."

Canberra is iffy, as it is a licensed version of the English Electric Canberra - obviously a British candidate. It was modified, namely in crew seating and engines, coming out slightly heavier and just a little faster, but performance and appearance were not too far removed from its heritage. I had considered this, but decided the Brits should get first dibs.

I finally went to the National Museum of the U.S. Air Force in Dayton today for the first time.  It was really awesome and overwhelming.  I only had a few hours, so I grabbed pictures of airplane text to read later, and tried to just get through the interesting parts -- pre-WWII, WWII, Korea -- and saved the rest for a visit next year.  Douglas Skyraider was one of the highlights -- absolutely massive in person.  Unbelievable.

 

I am thankful for your feedback as I try to learn more about these things.  I shouldn't be crossing things off until I know details.  Work in progress!

One way to reduce complexity is to begin with the end (jets ~1950) and go backwards.

 

Arranged in this manner, the existing in-game aircraft make those not yet in-game more apparent.

 

Two easy/obvious choices would be:

Tier IX:  Republic F-84 Thunderjet (straight wing)

Tier X:  Republic F-84F Thunderstreak (swept wing)

 

Tier IX:  Grumman F9F Panther (straight wing)

Tier X:  Grumman F9F-6 Cougar (swept wing)

 

The all-weather interceptor / night fighter category stemming from Northrop P-61, and North American F-82, would have to be somehow more compelling than the above, such as changes to the radar system, but I speculate.
