Ancient shield

Ancient Shields:
Being the first known to develop shield technology, the ancients possesses the most varied and powerful shield to exist.

Since the first ships created like the Destiny to the most advanced city-ships, the shield technology of the ancients seems to always dependent of the amount of energy directed to the shield.

Destiny-Class:
To be a Millenia-Build and damaged ship, the shield on the Destiny are very advanced. At least, with minimal energy, is capable of entering a corona of a star (is unknown if the shield was built specifically to this conditions or not), in addition is capable of withstanding bombardment of energy weapons of other ships for prolonged periods of time and even, although with effort, withstands the corona of a blue super-giant star (O-Class of 24 solar Masses).

The asurans use old lantean/ancient technology. All their ships have shield (except their Gateships) but these are inferior to those of the Ancient Fleet.
The shield in his Cruisers are capable of withstanding Mark VIII missiles from the Apollo, and their Aurora-Class shields only are capable of withstanding 3-4 shots from the asgard beam weapons.

With Limited Knowedge:
Anubis uses a limited ancient technology knowedge to upgrade the shield in his Ha´Tak-Class ships and in his Mothership.

Meanwhile a Goa´Uld Ha´Tak-Class ship is only capable of withstanding 12 shots from another Ha´Tak-Class ship, the new Anubis-Upgraded Ha´Tak-Class can withstand about 50.

His Mothership was even more powerfull and was capable of withstand 150 shots from an entire fleet of Ha´Tak-Class ships.

Aurora-Class Ships:
==== The ships on the Aurora-Class ships are very powerful, even without a ZPM, these shield are capable of withstand about 150 shots from a Wraith Cruiser (the Upgraded Daedalus is only capable of withstand 100) and the explosion of a Supervolcano 10000 times more powerfull that St Helens Mount (about 3500000 Megatons of TNT for 4,1 seconds (800539000000 Terajoules in total). ====

Atlantis Shield:
==== The shield of Atlantis is the most powerful shield never created. Powered by 3 ZMP´s is capable of things such protecting almost a whole planet of a coronal mass ejection, being submerged many hundreds of meter under the sea for 10000 years, being attacked by the Wraith Hive ships for years. ====
