Freyr's O'Neill

"The vessels you face are far superior to the one you attacked. Challenge us at your own peril."

- Freyr

Freyr's O'Neill was an O'Neill-class warship, under the command of Freyr, which was part of a fleet sent to rescue Thor from Anubis.

History
In 2003, Osiris successfully attacked a Bilskirnir-class ship, piloted by Thor, over a planet protected by the Protected Planets Treaty. Because, at the time, no Asgard ships were available, SG-1 was sent to the planet where an Asgard scientist, Heimdall, was left stranded in a research facility beneath the planet's surface.

Eventually, the team was able to rescue both Heimdall and Thor, who had been captured by Osiris. However, upon leaving the planet in the Tel'tak in which they came, they were fired upon by Goa'uld Death gliders. Moments before their destruction, however, three O'Neill-class ships, commanded by Freyr, came out of hyperspace directly in front of them. Seeing that their ships were no match for the three Asgard vessels, Osiris' Ha'tak departed peacefully, and the team was saved.
