to steal the Project Genesis materials from its creators, Drs. Carol and David Marcus, at the Regula 1 science station.
Dr. Carol Marcus requests assistance from Admiral Kirk, who is aboard Enterprise during an Acadamy training
cruise. Kirk assumes command of the ship and heads to the science station. En route to the station, Enterprise
is attacked by Reliant under Khan's command. After taking heavy damage, Enterprise is able to disable
Reliant and flee to the station. At the science station, a landing party from Enterprise discovers most
of the Project Genesis science team dead but the Reliant's captain and first officer alive. The landing party
learn of a cave created by Project Genesis experiments under the surface of Regula I.
Once there, the landing party find some of the science team alive including Drs. Carol and David Marcus. However, Khan
is able to obtain the Genesis Torpedo and other materials related to the project. Enterprise attempts to flee
into the Mutara Nebula and Reliant pursues the damaged ship. In the nebula Enterprise and Reliant
battle each other and Reliant is destroyed along with the entire Mutara Nebula when the Genesis torpedo is
detonated aboard the ship by Khan in his attempt to destroy the Enterprise. Spock dies from radiation poisoning
after successfully restarting the ship's warp drive, allowing the ship to escape destruction, but not before

space. The torpedo gently lands on the newly-formed Genesis Planet.
(ST3) As the Enterprise returns to
Earth, Spock's body is reborn on Genesis. The Oberth class science vessel USS Grissom begins to
survey Genesis but is destroyed by a Klingon Bird-of-Prey. Despite the destruction of the Grissom, two members
of the ship's crew; David Marcus and Lt. Saavik survive on the planet but are located and captured by a Klingon landing
party. On Earth, it is discovered that Spock's katra resides in McCoy's mind. Kirk asks for permission to go to
Genesis to retrieve Spock's body but is refused. He and his senior officers steal the Enterprise and head to
Genesis. Upon arrival, Enterprise encounters the Bird-of-Prey and a brief scuffle between the ships occurs,
disabling both. Kruge, the Klingon commander, states he has prisoners on the surface and orders the death of one of
them. Attempting to protect Saavik and the reborn Spock, David Marcus, Kirk's son, is killed. Kirk surrenders and
Klingon troops board Enterprise however, Kirk and his crew activate the ship's auto-destruct sequence and beam
down to Genesis. Enterprise explodes in orbit, killing most of the Bird-of-Prey's crew; its' remains tumbling
into and burning up in the atmosphere.
On the surface, Kirk and his crew locate Savvik, Spock's regenerated body, the body of David Marcus and the Klingon
guard who is shot by Kirk. Kruge returns to the surface, Kirk's crew is beamed up to the Bird-of-Prey and Kirk and
Kruge engage in hand-to-hand combat as the planet tears itself apart. Kirk kills Kruge, contacts the Bird-of-Prey and
beams up to the ship with Spock's body. Under Kirk's command, the Bird-of-Prey flees Genesis as it explodes and heads
to Vulcan to re-fuse Spock's katra with his body which is ultimately successful.
2286: (ST4) Following three months on Vulcan, Kirk and company choose to return to Earth to face
judgement of the crimes the committed while saving Spock. En route, they learn that the transmissions of an orbiting
probe of unknown origin is causing enviromental havoc to Earth, particularly its' oceans. Spock determines that the
probe's transmissions could be answered by humpback whales which are extinct on 23rd Century Earth. To save
Earth, Kirk decides to travel back in time using the "sling-shot effect" and retrieve the despritely whales in the past.
With assistance from 20th Ceteasian biologist Dr. Gillian Taylor, Kirk and his crew are able to bring two
humback whales to the 23rd Century and release them in San Fransisco Bay. The whales communicate with the
probe and it departs Earth without further incident.
In the Federation Council Chambers, the Federation President announces that all but one of the charges against Kirk
and his crew are dropped "due to mitigating circumstances". The remain charge of disobeying a superior officer is
solely against Admiral Kirk. The Federation President announces that the Council's judgement against Kirk for
disobeying the orders of the Starfleet Commander-in-Chief, he is demoted from Admiral to Captain and granted the
opportunity to command a starship again. Starfleet launches and commissions the second Federation starship to bear the
name Enterprise. The vessel is a refit Constitution Class starship, bears the registry number NCC-1701-A
and is placed under Kirk's command.
2287: (ST5) Starship Enterprise-A is hijacked by Spock's half-brother, Sybok, who pursues his visions of God. The Transwarp Development Project is deemed unsuccessful by Starfleet, but believes that Excelsior has potential and decides to refit the ship with standard warp drive.

Commander Hikaru Sulu, helmsman of Starship Enterprise, is promoted to Captain and given command of Excelsior, beginning a three-year mission of mapping gaseous anomolies in the Beta Quadrant of the galaxy.
2293: (ST6) On its return journey home, Starship Excelsior is hit by a massive shockwave
created by the explosion of the Klingon moon Praxis. The moon was the Empire's key energy production facility and its'
loss cripples the Klingon economy and causes irrepapable damage to the atmosphere of the Klingon homeworld. Starfleet
Command sends the Enterprise to escort the ship transporting Chancellor of the Klingon High Council and his
staff to Earth for peace negotiations. During the voyage however the Chancellor is assassinated and Kirk, along with
Dr. McCoy, is arrested for the assassination. The new Chancellor, the deceased Chancellor's daughter, negotiates with
the Federation President for a new secret and neutral location for peace talks. Kirk and McCoy are tried and convicted
in the assassination and are sentenced to life in prison on the penal asteroid of Rura Pethe. Kirk and McCoy escape
from prison and are rescued by their ship. Kirk and his crew determine that there is a conspiracy taking place to
prevent peace and the conspirators include Starfleet and Klingon military officers. They also learn that the new
location of the peace talks is "Camp Khitomer, near the Romulan border", from Captain Sulu of the Excelsior and
head there to prevent the possibility of another assassination.
Upon arriving in the star system that Camp Khitomer is in, Enterprise is intercepted and attacked by a Klingon
Bird-of-Prey that can fire its' weapons while cloaked. The one-sided battle results in heavy damage to the
Enterprise as the Excelsior arrives, which is also assualted by the cloaked Klingon ship. Aboard
Enterprise, Spock and McCoy modify a photon torpedo to detect the ionized gas exhaust of the Klingon ship. Once
launched, the torpedo homes in on and hits the Bird-of-Prey allowing Excelsior and Enterprise fire a
torpedo barrage that destroys the once-cloaked Klingon ship and kills a number of the conspirators. Kirk and his crew,
along with Sulu and a contingent of his ship's security personnel, prevent the assassination of the Federation
President and the new Klingon Chancellor and capture the remaining conspirators. The peace negotiations continue and
successfully establish the Khitomer Peace Accords between the United Federation of Planets and the Klingon Empire.
Following its brief, seven years of service to the Federation, Starship Enterprise-A returns to Earth and is
decommissioned by Starfleet as the ship's senior officers retire.
(ST7) A modified Excelsior
Class starship is commissioned into the service of the Federation and Starfleet as the third ship to bear the name
Enterprise. The vessel, registered as NCC-1701-B, is launched under the command of Captain John Harriman with
Ensign Demora Sulu as helmsman and retired Starfleet offiers James T. Kirk, Montgomery Scott and Pavel Chekov onboard
as honored guests for the maiden voyage. During the maiden voyage the ship receives a distress signal and Harriman
decides to help despite the ship not being fully manned or outfitted. Enterprise-B is able to save 47 refugees
but is caught in the gravitational pull of the energy ribbon that the ship encounters. Captain Kirk personally
reconfigures the Enterprise-B's navigational deflector to fire a antimatter discharge, freeing the ship.
However, the section of the Enterprise's secondary hull that Captain Kirk is in is hit by the energy ribbon.
There is no trace of him and it is reported that he was killed (in action), saving the lives of others.
