This is a theme i made after watching the film in anticipation of the F-14 module.
Enjoy.
Extract the zip file to "%USERPROFILE%\Saved Games\DCS".
Launch the game and navigate to Option > Misc > Theme and select "TopGun".
If you don't like the wallpaper feel free to replace "base-menu-window.png" and "loading-window.png" with a picture you like.
