Star Trek’s Biggest Plot Hole Is Actually a Major Problem for Wrath of Khan

Along with being the best Star Trek movie, The Wrath of Khan has one of the biggest inconsistencies that bothers die hard fans. In the movie, Khan recognizes Chekov, even though the two of them never met in the original series episode, “Space Seed.” But that issue is tiny compared to the real plot hole that sits in the very center of Wrath of Khan’s story.

In Star Trek II: The Wrath of Khan, Chekov and the crew of the USS Reliant are on a mission to find a lifeless planet that can be used to test the Genesis Device. A team beams down to Ceti Alpha VI to evaluate the planet, and soon enough they are captured by Khan Noonien Singh and his team. All of this is odd to Chekov, because Khan should be on Ceti Alpha V.

That is when Khan reveals the truth: they are on Ceti Alpha V. As the onetime ruler of a quarter of the Earth explains, just six months after Captain Kirk stranded Khan and his crew on Ceti Alpha V, Ceti Alpha VI exploded, shifting the orbits of all the planets in the system. And that is where the plot hole comes in.

How Did The Starfleet Miss Such An Obvious Change?

Because the planets are given numerical names, it is clear that the Ceti Alpha system, located in Sector 25712 of the Alpha Quadrant, has been fully mapped out by Starfleet. They would have left sensor and/or survey buoys behind that would keep tabs on what was happening in the sector. But somehow, for 15 years, no one knew an entire planet had exploded.

Setting aside that Starfleet never bothered to check on the crew of the SS Botany Bay, it’s hard to believe that a planet unexpectedly exploding, causing an complete shift of the other planets in that system, would go unnoticed. Even more, Starbase 12, as discussed in “Space Seed,” is in the next system, Gamma 400, and its own instruments should have picked up on the event.

Wrath Of Khan Is Still Great, Despite The Plot Hole

None of this is enough to take away all that makes Wrath of Khan great, but it does create a number of questions about Starfleet’s methods. Making things worse is that Starfleet’s attention toward the Ceti Alpha system is still poor generations later. In the Lower Decks episode “An Embarrassment Of Dooplers,” it is revealed that Mariner stranded someone on Ceti Alpha IV believing it contained life.

Of course, Mariner isn’t the most truthful member of Starfleet, so she may have just been trying to get out of trouble. And, as Boimler points out, it wouldn’t be the first time she had done something like that.
