Two ships of the Tau'ri fleet.

"How many ships do we have available?"
Rodney McKay[1]

The Tau'ri Fleet includes all Earth-built space vessels, as well as those acquired from ally and enemy races. These ships serve as a means of defending Earth from various alien threats and also as a means of transportation to the Pegasus Galaxy where the city, Atlantis resided before its return to Earth in 2009.

Fleet history

Early attempts

"Up till now, we haven't had a platform from which we could launch an attack against a Goa'uld ship... now we do."
Samantha Carter[2]

The Stargate Program was created with a mandate of acquiring knowledge, allies, and technology for the defense of the Earth. To this end, significant focus was placed upon the development of spacecraft capable of defending Earth from orbital attack. By the year 2000, after over five years of researching alien technologies discovered on off-world missions, along with billions of dollars of work, several prototype models, and several failures, the Tau'ri were eventually able to construct their first glider vessel based on alien technology. That was the X-301 Interceptor - a Tau'ri/Goa'uld hybrid. While it initially showed great promise in fulfilling this role, the craft ultimately failed due to its heavy reliance on alien components. (SG1: "Tangent")

The F-302

"Now, while many of the 302's systems were retro-engineered from Goa'uld technology, it is entirely human built."
Samantha Carter[3]

By 2002, following the failed flight tests of the X-301, the United States Air Force took an entirely different approach. This would result in the F-302 fighter-interceptor. Unlike its predecessor, the F-302 was built entirely using technology developed on Earth or reverse-engineered from Goa'uld equipment. F-302 fighter-interceptors are now the standard fighter-craft used by the military in the Stargate program, and they are stationed on all Tau'ri Battleships and major off-world bases. (SG1: "Redemption, Part 1", "Fallen")

Introduction of the Battle cruiser

"The Stargate Program has succeeded in acquiring alien technology. So now it's time to devote our resources to exploiting those technologies for planetary defense, namely by building more Daedalus-class ships."
Senator Fisher[4]

It was not long before Earth was able to create its first (and for a long time, only) interstellar battlecruiser, the Prometheus, introduced in 2003. While the F-302 is generally sufficient to successfully challenge its alien equivalent, the Prometheus was still inferior to the highest classes of battlecruiser operated by most other prominent races in the galaxy. Despite this, Prometheus represented a massive step in the Tau'ri's development. It played a major role in both the Tau'ri-Goa'uld war and Ori crusade, until it was ultimately destroyed in a battle over Tegalus in 2006. (SG1: "Ethon") Though plans were made to construct an entire fleet of BC-303s, the introduction of the Daedalus-class battlecruisers in 2005 rendered the craft obsolete, leaving the Prometheus as the sole vessel in its class. (SG1: "Enemy Mine", "Moebius, Part 1")

With the assistance of the Asgard, the Tau'ri were able to develope their most advanced ship to date, the Daedalus-class Deep Space Carrier. Since their creation, numerous 304s have been constructed. These ships are among the most advanced creations in the Tau'ri's possession and represent the ultimate culmination of everything the Stargate Program sought to achieve — the acquisition of technology capable of defending Earth from its enemies. These ships rival those of most races and have ascended the Tau'ri to a place of major power in both the Milky Way and Pegasus galaxies. (SGA: "The Siege, Part 1", "SG1", "Unending")
