Civinator -
I should have mentioned this is actually the third game I am playing on your mod. The first I played on 240x260 huge, regent, continents, 60% H20. Unfortunetly I don't know the turn times because that game was on my old computer. I didn't even notice, but you are correct I haven't received a single SGL this game (could be I'm now playing on diety though

).
If I am understanding you correctly, if I had added the units using 1.00 editor I would have SGL options and perhaps no turn time issues?
I'm actually going to download version 1.3 now and start playing that with no modifications so I can know if I need to return my $2,400 computer

.
For the units I didn't alter the specs where possible to not throw off game balance I just wanted my own units!
Arleigh Burke Class: same as guided missile destroyer
Ticonderoga Class: same as guided missile cruiser
Perry Class: Cold-War era guided missile and anti-sub frigate. (I actually don't recommend adding this as you get guided missile destroyer/cruisers so soon after cold-war in your tech tree)
Ohio Class: same as other SSBN's (12/6, 6MP), but +1 transport capacity. 4 SLBM's = 1 capacity so a total of 6. According to most publications compared to other nations ballistic missile submarines this is true. Specifically, the Russian Typhoon class (20 SLBM's compared to 24 for the Ohio class). I would recommend autoproducing all modern subs as most nations only have one or at most two shipyards capable of producing nuclear naval vessels. The US only has 18 SSBN's, but they pack a punch.
Virginia Class: would have to expand to add other nations attack subs, but I used 14/8, 8MP. Modern attack subs are extremely fast in MIL power (much faster than published numbers) and are considered a dangerous threat to carriers. A lot of nations(Germany, Sweden, China, Norway to name a few) are now producing diesel electric subs that are so quiet they are sinking US Carriers in war games. Ohio Class cost $2B which is about the same cost as a B-2 spirit bomber, hence I also moved up shield cost to 360. I am considering adding stealth attack, but the units would need to be autoproduced or some other precaution as to not unbalance game play by being able to sink carriers easily.
On a huge map I don't see a nation having 8-10 attack subs as an issue.
F-35A: Would need to be available to a lot of countries that are in the program. Stats are 9/7 (10) with 2ROF. Stealth is added with a range of 16 for a shield cost of 300. This essentially replaces the standard stealth fighter for countries involved in the project.
F-22A: Specs of 11/10 (4) 1ROF, 18 range, and stealth. Shield cost is 420 (almost a waste at twice the cost of an F-15, but they are good planes just like in real life). F-15 cost is $55M and F-22 is approximately $170M. The F-22 is essentially only an air-air platform, but they are good at what they do. Since they have stealth I don't feel they unbalance game play because you can't attack and knock out a nations air force, they are a killer defensive weapon though.
You could add the Sukhoi TA-50 for russia, and PAKFA for India (same plane). These are 'comparable planes' to the F-22, but not operational yet. I don't want to bore you with details, but there are actually two different methods of stealth that are in play for design. Both RAM (Radar adsorbent materials) and LO(Low observable) technologies had to be developed for the newest stealth planes. LO observable is just how the design reflects radar waves.
F-16 Block 60: The US actually sells F-16's to a ton of countries(Turkey, Korea, Israel, etc), but only sell the block 60 to the UAE. If you want to use the block 50/52 there about 5-8 countries that would get the unit. It is slightly cheaper than an F-15, almost as effective, but one engine makes the range 14. Stats are 9/7 just like a standard jet fighter.
F-18E/F: I don't recommend adding this as it is essentially the same plane as the F-15, but Canada and Australia are the main purchasers of the super hornets.
If you think you want to add any modern units WWII-Present, I'm happy to do in depth research to make sure the stats are correct.
