Ok, there's
-A dock- drive to the end of the runway, there's a path going down to it
- Snowstone
- That army base runway in Snowstone Valley
-The Convoy (found in the road surrounding Krakabola Volcano)
-Sky Park City (that stadium south of Wright Airport. Spawn at Wright Final and look directly backwards, you should see it in the mist)

Unknown if Mobile has it or not;
- Is there any ships in Mobile? Then there would be the USS Tiny 1, USS Tiny 2, and the USS Beast (The USS Tiny 2 is located about 1/3 of the way from Yeager to Snowstone)
- There might be the Kraken

Sorry, no Maywar in Mobile

P.S I play on computer, so a few unknowns.

@LiamW Thx dude!

Its under the ice base at sea level in a cave @EpicPigster1

@Awsomur oh yeh thats the hangar

That too. @CaesiciusPlanes

Yes. Take off from Yeager and look down near the foot of the runway. @UssInvincible

@Awsomur theres an water shed?

Okay, thanks. That's a very interesting conversation. @Tully2001

Hmm. May I ask where they confirmed this? @Tully2001

Thanks@Awsomur @EpicPigster1 @LiamW @Tully2001 @UssInvincible @MechWARRIOR57

Besides it's a Kraken, not Cthulhu. @Tully2001

USS Beast, Ice Base, and a custom one: the Water Shed near Yeager.

@LiamW Wait there is?! Can you tell me how to get to it?

I assume you know about avalanche

Undermountain docking bay under the ice base

There is Ice base, Uss Beast carrier, north runway, the kraken (custom location) then there's ramp it up in maywar, and I think that is it

no, at least none that I know of
