The Yorktown, under the command of Captain Joel Randolph, was disabled by the Whale probe near Earth in 2286. During his distress call, Randolph noted the Yorktown was without power, and their chief engineer constructed a makeshift solar sail in the hope that, once deployed, it could generate power to keep the crew alive.

Prior to the 2270s Fleetwide adoption of the Enterprise delta shield as an insignia, the assignment patch for Yorktown was a long rectangle (similar in proportions to the assignment patch for Exeter) with a scalene triangle superimposed on the top right corner.

Reginald Chandra was the commanding officer of Yorktown from 2259-2269. (Orion Press: Lexicon C-D, 2010 revision) He served on the trial board during Kirk's court-martial for the murder of Benjamin Finney. (TOS: "Court Martial")

Number One was offered command of the USS Lexington in 2261, which she turned down. Three years later, she also turned down command of the USS Antares. When Pike was promoted to fleet captain in 2264, she was offered -- and accepted -- command of Yorktown.
When the incident that crippled Pike occurred in 2266, she and Yorktown were on patrol in the Neutral Zone, and received a communiqué from Commodore Mendez. While Number One traveled to Starbase 11 as quickly as possible, Pike had left orders that no one -- not her, not Philip Boyce, not Robert nor Sarah April -- would be allowed to see him.

Sometime prior to stardate 3714.28, Yorktown, commanded by Captain Eric von Ryan, discovered the damaged, uninhabited hull of IKV Krieger, a Klingon D7-class battlecruiser near Starbase 16. The ship was used to add to Starfleet's intelligence on the class of ships. (Star Fleet Assembly Manual 2)
In 2274, the ship was refitted.
Following the Whale probe incident the Yorktown was converted into the USS Enterprise-A. (Ship Recognition Manual, Volume 4: Starships of the Original Series Era)
