Asgard shields are the primary defensive technology used by Asgard and Tau'ri spaceships, and are among the most advanced shields known to exist. The technology was shared by the Asgard with the Tau'ri in thanks for their contributions in defeating the Replicators, giving Tau'ri fleet|Tau'ri ships a great advantage over the advance races of the galaxy.

Functions

Asgard shields create an elliptical "bubble" around the spaceship they are equipped to, which absorbs and diffuses the energy from weapons fire. When hit with weapons fire, Asgard shields have a distinctive bluish color and an effect similar to that of boiling water or mist dissipating the energy. This shield matrix will gradually degrade under fire (rather quickly under sustained bombardment, but only if the shield is attacked by powerful weapons), resulting in more and more energy from attacks bleeding through and causing damage to the ship. However, as pointed out, the weapons impacting the shield must be quite powerful, otherwise the shields will hold even under sustained fire. Lesser weaponry like the one on a Ha'tak vessel have little to no effect on the shield even if multiple vessels are bombarding it simultaneously. Additional energy can be allocated to the shield matrix to reinforce it, but the only way for a ship to ultimately survive a continued assault is to withdraw and give the generators time to recharge and replenish the matrix. {{Cite|SGA|The Siege, Part 3|No Man's Land}}

Asgard shields far outstrip the much more primitive Shield#Goa'uld|Goa'uld shields in effectiveness. Despite this, they become considerably less effective when facing foes of a comparable technological level. The exact strength of an Asgard shield, like most Asgard technology, appears to be relative to the amount of power channelled into them, meaning the shields on Asgard fleet|Asgard ships are much more powerful than those of Tau'ri spaceships unless a Zero Point Module or equivalent power source is interfaced, which renders them even more powerful than the shields featured on Asgard vessels. The most advanced shields ever developed by the Asgard were equipped on the Odyssey before they committed mass suicide, allowing the ship to survive sustained fire from the Ori energy beam weapon|central weapons of multiple Ori warships for several minutes, a most incredible feat currently unmatched by the shield technology of any other race that has battled the Ori. {{Cite|SG1|Unending|The Ark of Truth}}
 

With a Zero Point Module|ZPM or another comparable power source, the shields can withstand virtually anything. Even without a ZPM, the Asgard shields offer protection from Drone weapons. {{Cite|SGA|Be All My Sins Remember'd|}}
