In 2377, Lieutenant B'Elanna Torres participated in a Boray conference on transwarp theory in the Delta Quadrant. In 2376, the Pathfinder Project wasted six months attempting to develop a transwarp probe, based on simulations made by Reginald Barclay. In 2375, Voyager used a transwarp coil stolen from a Borg sphere to create a transwarp conduit to traverse twenty thousand light years closer to the Alpha Quadrant, thus cutting about fifteen years off of its journey. Instead, it came through flowing tachyons almost to a warp core breach. In 2374, Seven of Nine attempted unsuccessfully to modify the systems of the Federation starship USS Voyager to create a transwarp conduit. In 2374, the USS Defiant studied a rare subspace compression anomaly in the hopes of collecting data relevant to the development of transwarp corridors, which are approximately fifty times faster than highest warp of Starfleet ships. ( VOY: ' Distant Origin') This kind of transwarp did not appear to use transwarp conduits. In 2372, the USS Voyager encountered the Voth. The Voth employed ships that were equipped with transwarp drives.

Although this form of travel was found to have severe, unanticipated side effects, Paris was the first person in Starfleet to cross the transwarp threshold. In 2372, Tom Paris of the USS Voyager managed to break the transwarp threshold in the shuttlecraft Cochrane after discovering a new form of dilithium. Geordi La Forge of the USS Enterprise-D likened going through a transwarp aperture to ' falling into a fast-moving river and getting swept away by the current.' ( TNG: ' Descent') In 2370, the ship used by the rogue Borg that were under the control of Lore used a conduit during an attack on Federation space. This encounter remained unreported at the time. ( VOY: ' Unimatrix Zero') This technology was first encountered by the Federation in the 2350s by the crew of the USS Raven. The Borg used transwarp signals for communication and the Borg transwarp drive was based on generating transwarp conduit through transwarp space.

However, the effort was ultimately unsuccessful.

The Federation also attempted to develop a transwarp drive in the USS Excelsior in 2285, termed ' The Great Experiment'. In 2259, John Harrison implemented this technology to a portable transwarp beaming device. The complete transwarp beaming technology was introduced to the alternate reality in 2258 by Ambassador Spock. The theory was postulated and perfected by Montgomery Scott, but was only effective at a few dozen light years and only a limited amount of mass could be transported. This transporter technology allowed the instantaneous beaming of living beings between planets and distant star systems, or even onto a starship traveling at high warp. The Federation developed transwarp beaming by 2387.
