A higly manouverable small 5th generation stealth fighter. Can go up to mach 1 if you try hard enough and is equiped with two PLSLs or Pulse Lasers, hidden on the wings of the plane. Has the capacity to land on aircraft carriers if you want to, but its hard. AG1 for hook.

Backstory: Developed as Brazils first 5th Generation fighter in the late 2020s, the F37U was to replace both the JAS 39E Gripen NGs, which, altough newly bought, were getting outdated due to 6th Generation fighter having a lot of progress, and the rest of the ancient fleet of F5E/BR Tiger 2s. The project was completed in 2033 and after 2 months of trials, entered mass production. They were so good that, Argentina, Peru, Chile, French Guiana, Indonesia, Unified Vietnam and other countries bought at least 100 fighter each. It recieved its nickname of "Trono Dourado" or "Golden Throne" due to its prototype colors. It was first given to the Esquadrão Ceará, or Ceara Squadron

P.S: if you are wondering, im brazilian, so its easy to translate all of this stuff. No google translate was used (sorry for the brag, but i had to do it to 'em).
