In Star Wars Episode 9: The Rise of Skywalker, Rey flies Luke's old X-Wing, which has been under water on Ahch-To for a number of years. Assuming that the ship didn't suffer enough corrosion or damage that it was unusable, how did Rey manage to fly, let alone navigate, to Exegol without the assistance of an R2 (or R4, etc) unit?

My understanding is that droids did most of the take off/landing of the ships, navigation, targeting, and so on, leaving the pilot to pilot the ship and make the instinctual decisions. I know Luke flew back from destroying DS1 with R2-D2 severely damaged, but that was a short flight in comparison.

    @Valorum Why look for the Wayfinder the then? Jan 6 '20 at 23:38

    Luke went to Dagobah without using a navigational computer.

    Since Luke didn't have an Astro-droid when he traveled to Ahch-To, presumably he retrofitted his X-Wing with a cheap after-market Navicomp

    Plus Luke was using bits of the ship as his door

Although it's been confirmed (repeatedly) that the T-65B X-Wing Starfighter has no built-in Navicomp capability, we do know that Luke somehow managed to travel to Ahch-To without an Astromech droid given that we find R2-D2 rotting under a tarpaulin on Yavin IV.

Since the socket in the fighter is seen to be empty, the most likely option is that he retrofitted his ship with a simple Navigation Computer, noting that technology has moved on significantly since the days when Astromechs were required, to the point that even small First Order TIE fighters now have full hyperdrives.

It's also possible that Rey (scavenger par excellence) was able to cobble a working Navicomp out of components that survived the landing and subsequent bonfire of her TIE

  • Could you clarify the "repeatedly"? I see only one reference in the link you connected that word with.

    @Marakai - It's mentioned in Star Wars: Ships of the Galaxy, Rebel Starfighters Owners' Workshop Manual, The Official Starships & Vehicles Collection (#02) and many other sources. This seems to be the agreed form of words; [2]: i.stack.imgur.com/rN2JB.png

  • Resistance X-Wing fights also have hyperdrives (at least from TFA and onwards), after Starkiller Base is destroyed they jump to hyperspace Jan 7 '20 at 7:00

    @SpacePhoenix - It's not the possession of a Hyperdrive that's the issue, it's whether an X-Wing's hyperdrive can operate without an Astromech droid

I wondered this myself, but then figured that the Sith wayfinder device was what gave her the co-ordinates to get to Exegol. After all, that was the purpose of the device.

Obviously, this leaves the problem of Luke traveling to Ahch-To without an astromech to calculate the hyperspace co-ordinates. So, as suggested by other answers, he may have had the ship retrofitted with a navicomp. Or, he may have used the Force.

    Maybe Luke got a lift and just used his X-Wing to land? I mean the map of where he went had to leak out somehow...

  • Alternately, the ship ended up in the water because he didn't have a droid to help him land. Jan 8 '20 at 19:35
