Underwater Missions Not Triggering

[Armitage451]

End of December 01, and I am yet to see a single underwater mission. At this point I have an armory full of various underwater gear (chiller, frogman, etc) and basic weapons to use - and not one mission.
Starting to get worried that there is something wrong with my game - is this normal?

I finished the research that should've unlocked those missions months ago - unless I am missing something?

Definately got !Undersea Treasures! researched?

Double check using the in game tech tree viewer.

Make sure you have a craft ready in a hangar that has SUB as one of it's capabilities~ Your Flagship/Worm/Snake/Jellyfish/Airtruck/Blowfish. In my experience, it won't spawn missions if you don't have a suitable craft for it. The Firefox is technically a sub but it doesn't seem to qualify for 99% of underwater missions since it's also a wide craft. Until I maintained a Jellyfish with a dedicated underwater team in my 3rd base I didn't get many underwater missions at all.

If you've definately got both ready, it's possible the RNG just hates you (I had one brothel mission in 7 months once). It's not hugely important at your stage of the game anyways. You will eventually want to access Dreams and Chants of the Deep stuff, but it's likely a while off.

I got some underwater missions when I still only had an airbus, so I think they'll spawn as long as you've got the right research done.

It's probably just bad luck, those missions are pretty rare.

Not having a suitable vehicle should not be an issue. I often purchase submarines or ground vehicles for specific missions and then sell them afterwards.

It was just the case of RNG hating me 
took couple more months and finally had an underwater mission spawn in.
