This is a Brazilian Air Force (FAB) livery using the HAVEGLASS style of coating.
The way Brazil names its aircraft is very similar to the USAF thus the "Su-33KB", which would be the Russian designation for the export version (K) to Brazil (B), would have been called "F-33KB".
In the file, you'll encounter 4 different bort numbers for this livery. 4333, 4359, 4361 and 4327.
Brazil does not, and never has, bought or employed the Sukhoi-33. This livery is purely fictional and made for fun.
It is inspired by one of the prettiest birds of prey present in the Brazilian fauna the hook-billed kite - aka "anzoleiro".
