TOS Season 2

Summary
This season saw Ensign Pavel Chekov added to the regular bridge crew. Although his first appearance in had him operating the science station,  established him as the ship's primary navigator.

Following their introduction near the end of the previous season, the Klingons were established as major adversaries, appearing in three episodes,, , and. The second of those would turn out to be one of the show's most popular and influential episodes, introducing Koloth and the Tribbles, who reappeared on Deep Space 9, with other characters reappearing in the animated episode. The Romulans also made a brief reappearance in while Harry Mudd returned for a second tussle with the Enterprise crew in the comedic episode. saw Kirk and company paying a first visit to the mirror universe which also later featured prominently on Deep Space 9.

The show began to explore the rest of the Federation, with the Enterprise making its first trip to Vulcan as Spock underwent Pon farr in. saw the Enterprise transporting representatives of the Vulcans, Andorians, and Tellarites to a conference to admit the Coridans to the Federation, among them Spock's father Sarek. provided an insight into Kirk's early Starfleet career, revealing some of the details of his tour of duty on the USS Farragut (23rd century).

Although most episodes centered around the triumvirate of Kirk, Spock, and McCoy, the other regular crewmembers began to appear more. After first commanding the ship in, Scotty was firmly established as the Enterprise's third-in-command, with episodes like , , and giving screen time to his command. He was also given a spotlight in, in which he was accused of a series of murders. Chekov and Uhura were given a chance to accompany Kirk on an away mission in and Chekov also had a prominent role, and an opportunity for romance, in. Sulu, on the other hand, was absent from nine consecutive episodes in the middle of the season, the result of a film George Takei was working on over-running.

The Enterprise visited several planets based on Earth history, either by coincidence or as a result of human visitors, such as Ancient Rome, Chicago gangsters , Nazi Germany and the American Constitution. There were other surprising encounters with Zefram Cochrane, the father of warp technology, the Greek god Apollo and a giant space amoeba.

The show continued Gene Roddenberry's original idea of political fables, with two episodes identified as providing somewhat opposing commentary on the Vietnam War. saw the Federation and the Klingons supporting opposing sides in a civil war, with Kirk talking of the need to maintain the balance of power, while saw Kirk telling a race based around the American Constitution that the values of liberty and freedom of belief also applied to their enemies.

Background Information

 * There were some "upgrades" to bridge equipment made at the start of this season (most notably the helm console), but these changes aren't always visible because first-season footage was used in many bridge scenes. You can recognize this footage when you see the viewing screen and the back of Sulu's head – the navigator isn't shown because Walter Koenig hadn't signed on when this footage was filmed. The black viewer or scope at Spock's library computer station was replaced with a white one (that came with a knob on the left side). A similar scope was added to Scotty's engineering station.
 * For the second season, the production budget per episode was around US$185,000, slightly less than Season 1.
 * Lawrence Montaigne, who played Stonn in, and Mark Lenard were both being considered as possible replacements for Leonard Nimoy prior to the beginning of the second season if contract negotiations had fallen through. Nimoy's agent had asked for Nimoy's salary to be increased from US$1,250 per episode during the first season to US$9,000 for the second season.  Eventually a compromise figure of US$2,500 per episode was reached and Nimoy signed on for the second season. (Inside Star Trek: The Real Story, pp. 317-324)
 * Dr. McCoy's sickbay gained a lab this season. The back bulkhead of said lab appears to be one of the bulkheads of the SS Botany Bay from.
 * A new expanded engineering set was built, including a small set called "Emergency Manual Monitor" built on stilts that looked down onto the engineering set.
 * A completely new set called Auxiliary Control was also built.
 * In the second season more emphasis was put on the supporting characters (especially Scotty and Chekov), but the show didn't feature scenes of every-day activity around lower decks of the ship anymore as it did in the first season.
 * Beginning with Season 2, the episode titles and credits were in the same font as the series title. Also, DeForest Kelley's and Gene Roddenberry's names were added to the opening credits.
 * Also, during the opening credits, the Enterprise fly-by and the planet that the Enterprise orbited were different from that of Season 1.
 * Walter Koenig joined the main cast as the Russian navigator Pavel Chekov.
 * The theme music for the series was slightly re-arranged this season, with Loulie Jean Norman supplying vocal accompaniment.
 * Season 2 was a period of behind-the-scenes transition from Desilu to Paramount production. On, Gulf+Western's purchase of Desilu was announced. It was commemorated with a ribbon-cutting ceremony on 26 July.  Gulf+Western executives were known to have signed off on production of the then-upcoming Season 2 of Star Trek, as they would have been financially obligated to continue its production after the sale.  Therefore, Season 2 technically began filming as a Desilu/Gulf+Western co-production. (Sanders, Coyne Steven and Tom Gilbert.  Desilu: The Story of Lucille Ball and Desi Arnaz.  HarperCollins.  1994.  297-298)  However, the December 1967 intra-company merger between Paramount Pictures and Desilu caused later episodes of the season to be labeled "a Paramount production".  Episodes throughout the season thus have a variety of different ownership claims.  is a simple "Desilu production" under just the Desilu logo, while the later  displays the Desilu logo, but a Paramount Pictures Corporation copyright.
 * was the first to be filmed after the late July ribbon-cutting on the Gulf+Western/Desilu merger, but no episode of the season began filming prior to the February merger announcement.
 * Gene L. Coon remained the producer, but he was replaced mid-season by John Meredyth Lucas.
 * D.C. Fontana, who took the position of story editor near the end of season one, remained in this capacity during the second season.
 * However, after the departure of Rolland M. Brooks (the last episode he worked on was ), Walter M. Jefferies remained the series' sole art director.
 * Most of the seasons' episodes were helmed by one of three prominent directors, Joseph Pevney, Marc Daniels and Ralph Senensky. Assistant director Gregg Peters was promoted to unit production manager.
 * Andrea Weaver became the women's costumer for the series at the time begins production. She would remain with the show throughout the remainder of the season and half of TOS Season 3.
 * The first season and, , , and did not use a copyright until 1978 so starting with , all of the episodes have the correct copyright date to them at the end of each episode.
