Transport Units (Little Upsilon)

When I go to setup transport Units, it says I need Transport Airplanes. Naturally, I search in the world Market and realize, there are no transport Planes. I however did find, Air Transport, and Cargo planes.

My question therefore is thus: Assuming one of these two is what I need, which one is it?

Thanks in advance for speedy replies.

You need Military Transport Airplanes.

That's what they appear as on the World Trade page.

Lol, thanks for the help, I found them.
