Formed about 2,500 years ago when Emeria had just reached the Space Age (Tek Level 5), it replaced it's outdated seafaring predecessor, and took to the stars. Starting in true
Fast forward about 250 years. The devastating defeat to the Assyrian Star Empire forces change, not only from the strange, new orangle-clad Trianglist Heretics' advanced tek, but by pure necessity. The whole military underwent extensive renovation and modernization, which was led by the Assyrian overlords sent to impose their law on Emeria. From this effort, the Emerian Imperial Navy was born. To this day, it remains the vanguard of the Emerian Imperial Armed Forces, and is the other side of the coin from the ground-pounding Imperial Army.
That brings us to now.
The São Filipe is the Emerian answer to all other navy's destroyers. Designed after Praetorian contractors stopped working with the EIN, the São Filipe is designed to pack a punch, take lots of punishment, and outmaneuver other ships. Also note the hangar.
After the Atlantian War with Assyria ended in disaster and the resulting Assyrian-lead upgrade of the Emerian military took place, it became crystal clear to Emeria that it needed a more powerful navy. Emeria discovered the Praetorian Empire during the Second Battle of New York, and contacted them when that debacle ended. Desperate to rid themselves of the obsolete Vendettas, they eagerly sold a healthy amount (and continue to) to Emeria, and helped them chop up the ship and adapt it with Emerian technology.
The result was the San Lorenzo (and loss of Praetorian support when they passed off the design as theirs own), and it serves as the main body of the Emerian Navy.
Heavy Battleship Mk. III
Meaning, "the Donkey" in the Common Tongue, El Burro is a battleship with one ideal in mind: the complete destruction and utter annihilation of Emeria's foes. Designed to have a carry a full, miniature fleet of fighter aircraft and/or bombers, enough gun to smite a small fleet of pirate scum, and engines / slipspace devices powerful enough to match that of the major powers of the BrikVerse. Thanks to its armor, El Burro can take a good amount of punishment and dish it back out with equivalent, if not greater, malfeasance. Wherever Emerian interests lie, an El Burro battleship will be there, melting the foes of Emeria's might.
