2218, May 3
The U.S.S. "Constitution" (NCC-1700) heavy cruiser is commissioned. This starship class will total 14 ships and, as other heavy cruisers of similar design are constructed over the next century, this class will be uprated to match the current state-of-the-art technologies. The "Constitution" will be be the first ship to apprehend the smuggler Kojiro Vance, captain of the S.S. "Kobayashi Maru" (ex-"Gas'Tath") in orbit around Ti'Ruben, confiscating the contraband merchant ship. The U.S.S. "Constitution" will also be credited in verifying the existence of the D-7 "Klolode" class Klingon warships "Klothos" ("Carnage," KL 99970) and "Tabor" ("Powerful," KL 85269) on stardate 4517.23, and later the "Marta" ("Corona," ChR 333) in Romulan service on 6348.17. Later on, the U.S.S. "Constitution" will be the first starship to encounter a prototype Klingon "K't'inga" class battlecruiser, "Ykir" ("Usurper," KL 17675) in 2264 near Gamma Canaris and will sustain considerable hull damage. She will later serve as the lead vessel, again, for a new heavy cruiser variant named the "Constitution (II)" class, be recommissioned in 2271 and assigned to Fleet Subquadrant 3 South. The uniform insignia of the U.S.S. "Constitution" may take the form of a circle overlaid upon a horizontal ellipse

2220, July SECOND LYRAN-KZINTI WAR BEGINS
- The U.S.S. "Enterprise" (NCC-1701) is launched from Earth. Captain Robert April takes her out on a shakedown cruise, following her christening by the U.F.P.'s President Samuel Solomon Qasr. The "Enterprise's" First Officer is Shundresh, Chief Engineer is Kursley, Navigator is Lt. Po, and her Helmsman is Lt. Nobis [Star Trek Log 7, [Ships of the Star Fleet, U.S.S. Enterprise Heavy Cruiser Evolution Blueprints, The Making of Star Trek, Starfleet Handbooks]
- Captain Krenn in command of the I.K.V. "Fencer" captures a Willall ship. Analysis of the captured starship will give the Klingons dilithium-focused warp drive. Captain Krenn is later ordered to serve as an ambassador to the U.F.P., a long-duration voyage of over a year [TOS 16: "The Final Reflection"].
2220, September
- On September 8, the U.S.S. "Farragut" (NCC-1702) "Constitution" class heavy cruiser is laid down at Star Fleet Division, Puget Sound Yards, Earth [Ships of the Star Fleet, U.S.S. Enterprise Heavy Cruiser Evolution Blueprints]
- On September 13, The U.S.S. "Lexington" (NCC-1703) "Constitution" class heavy cruiser is laid down at Star Fleet Division, Puget Sound Yards, Earth [Ships of the Star Fleet, U.S.S. Enterprise Heavy Cruiser Evolution Blueprints]
2220, October 19
The U.S.S. "Yorktown" (NCC-1704) "Constitution" class heavy cruiser is laid down at Star Fleet Division, San Francisco Yards, Earth [Ships of the Star Fleet, U.S.S. Enterprise Heavy Cruiser Evolution Blueprints]
2221, January
- On January 3, the U.S.S. "Excalibur" (NCC-1705) "Constitution" class heavy cruiser is laid down at Star Fleet Division, San Francisco Yards, Earth [Ships of the Star Fleet, U.S.S. Enterprise Heavy Cruiser Evolution Blueprints]
- On January 5, the U.S.S. "Enterprise" (NCC-1701) heavy cruiser is commissioned with two (4680 TEV rarium) laser banks, monotronic computers, and a complement of 403. Captain Robert T. April takes her out on her first deep-space mission: galaxy exploration and investigation, beginning with the patrol of the 9th quadrant, from Alpha Centauri to the outer Pinial Galaxy limit. Captain April's "Enterprise" officers at this stage may consist of: Chief Engineer Charles Fourrier, Communications Officer Karen Van Fleet, Helmsman Luis Ferarra, Science Officer Gregor Allinsky, and Medical Officer Sarah April. Easily the most famous "Constitution" class starship, in her long service life she will be commanded by Captains Pike, Kirk, and Spock before her self-destruction in 2287. Her normal patrol zone will eventually be Fleet Subquadrant 3 South throughout most of her service life. A residence hull will honor the "Enterprise's" name at the First Fleet Star Fleet Academy. The "Enterprise" might be the first ship to utilize the classic arrowhead uniform insignia. The insignia's design is based upon the energy expenditure curves associated with normal space and warp drive travel established by Zefram Cochrane in the 21st Century [U.S.S. Enterprise Heavy Cruiser Evolution Blueprints, Ships of the Star Fleet, The Making of Star Trek, Star Trek Maps, Starfleet Academy Student Handbook, Starfleet Uniform Recognition Manual, TOS Giant Novel 18: "Federation"].
2222 FEDERATION-KLINGON WAR ENDS
- The U.S.S. "Farragut" (NCC-1702) heavy cruiser is commissioned. A longlived ship, she will be assigned to Fleet Subquadrant 1 South. Christopher Pike will serve aboard her as an Ensign in the 2230s and James Kirk will likewise serve aboard her in the 2250s (then under the command of Captain Garrovick). Garrovick will die with half his crew during the attack of a Vampire Cloud creature but the ship will remain in service. Captain Kelly Bogle will be in command of the "Farragut" c. late 2262 shortly before being assigned to Star Fleet's Plans and Policy commission. Captain Phillips will assume command of the "Farragut" in 2264 in time for the warp-powered shield test wargames with the "Enterprise." The "Farragut" will be one of three (then-reclassified) command cruisers in 2278 to be converted to a strike carrier. The ship will be refitted many times, and in the late 2280s to "Enterprise (II)" specs and assigned to Fleet Subquadrant 2 North. In the 24th Century she will continue as an active starship, rechristened the U.S.S. "Centurion" and crewed by Magna Romans, she will be commanded by Captain Lucius Aelius Sejanus. One of the residence hulls at the (Home Fleet) Star Fleet Academy in San Francisco will be named in honor of this ship, eventually lost in the line of duty. The uniform insignia of the "Farragut" may be two overlaid vertical circles with two inset horizontal circles [Ships of the Star Fleet, U.S.S.
