The timeline in which these events occurred was negated when Picard was able to stop the initial formation of the eruption.' ( TNG: ' All Good Things.') It was later discovered that the tachyon pulses themselves were what ruptured the subspace barrier between time and anti-time, creating the eruption in the first place. In an alternate timeline, Captain Picard ordered the use of an inverse tachyon pulse in three different time periods, to scan the interior of an anti-time eruption which existed in each period. The Enterprise generates an inverse tachyon pulse This forced Lieutenant Torres to eject the core. Five years later, Seven of Nine attempted to utilize the same procedure to create a transwarp conduit in an effort to facilitate Voyager's return to the Alpha Quadrant, but the tachyons flooded the warp core, threatening a breach.

In 2369, Commander Geordi La Forge, chief engineer of the Enterprise-D, was able to set up a temporary tachyon matrix in the ship's main deflector to simulate the pulses that the Borg used, and gain access to a transwarp conduit. The Borg utilized tachyon pulses of alternating frequencies to open their transwarp conduits. ( DS9: ' For the Cause', ' By Inferno's Light' Star Trek Nemesis) As of 2379, the Remans were able to equip the Reman Warbird Scimitar with a cloak which did not have this limitation. In 2372, the USS Defiant produced a tachyon surge when decloaking in front of the SS Xhosa, and in 2373, when a fleet of Romulan warbirds decloaked near station Deep Space 9, they produced a large buildup of tachyons. In addition, cloaked ships were known to produce detectable tachyon emissions. ( TNG: ' Redemption II' VOY: ' Flashback' DS9: ' Once More Unto the Breach') They were first observed being used by the crew of the Klingon vessel Ch'Tang, after conducting a cavalry raid behind enemy lines. As of 2375, the Dominion began employing long-range tachyon scanners to detect cloaked vessels. Six years later, Lieutenant Tuvok suggested initiating a tachyon scan of a nebula that the USS Voyager had encountered in the Delta Quadrant, in an attempt to reveal the presence of any cloaked ships which could be hiding inside. This effectively stopped the Romulan Empire's covert support for the House of Duras's attempts to take control of the Klingon Empire. In 2367, Captain Jean-Luc Picard instituted a tachyon detection grid on the Klingon-Romulan border, in order to prevent any cloaked Romulan ships from crossing the border undetected while cloaked.

In 2366, the non-corporeal species, the Calamarain, used a tachyon field to attack Q, who had been stripped of all of his powers by the Q Continuum and deposited on board the USS Enterprise-D. In 2151, Silik detected this radiation aboard Enterprise NX-01, and deduced that Daniels was on the ship, as Enterprise did not have any technology which emitted tachyons. Some of the 31st century temporal agent Daniels' equipment produced tachyon radiation.
