If I remember right, the Klingon Bird of Prey in The Search for Spock was the first time we saw a starship land. Did we ever see a landing of any kind of full size ship back on the original series? The way I understand the intentions of Star Trek is that capital ships aren't too big to land, but rather aren't designed with that in mind.
Outside of the Klingon Bird of Prey, have we seen starship landings before Voyager? Alien ships count, crash landings don't. That said, the crash of the Ent-D saucer is breath taking and still holds up for me in 2020.
I'm pretty sure the Defiant-class was designed with landing in mind. I mean, it's smaller than Voyager and kinda flat, so why not? I think the Equinox and Prometheus were capable of landings.
What other ships were designed to land by the production team, or at least look like they could land?
I wish we saw more of this in Star Trek. Not on the regular, but more often than what we've seen so far.
Why not? Because the Defiant is small, cramped, and adding landing gear and supporting anti-grav systems is a waste of space and energy.
The Defiant is not a transport, cargo ship, assault ship, evacuation ship, explorer, liner, or any thing else that needs to land or requires the expense to land. It is tough enough to survive a emergency landing, sure. It may even be designed so the pilot can do a semi-soft landing, it won't be graceful but it should land in a controlled fashion via RCS, impulse, timing, and the mark 1 eyeball. Whether or not it can take off again is another matter, but one of again probable brute force, as the hull itself is basically the landing gear in that case.
But the Defiant is a dedicated anti-borg ship killer. The Borg ships are in space, not on the ground (for the most part). The Defiant should not waste valuable space and energy on such a system.
Overall I loathed the whole idea, from the Intrepid to the Defiant to the Connie or NX or whatever. A Space/Starship should be solely interplanetary, interstellar. It can lithobreak without killing everyone on board or exploding, sure, but that's a bonus from the tough construction of the future; it shouldn't be a dedicated system. If you
have to land, sure, the saucer section can get you down there, but it probably won't be coming back up under its own power.
But the main job is to scoot from orbit to orbit, or star to star, it shouldn't have to deal with anything more than the uppermost layers of an atmosphere, and again it's brute-forcing it via the massive energy available to it than gracefully flying...or as seen in the movie, even
swimming.
That's what the shuttles are for- to transport personnel and materiel from ship to surface or vice versa; and that's the front that should be expanded on; we should see a lot more shuttlecraft and runabout size class for that heavy duty, especially in earlier works.
ENT did a sort of disservice by shoving in the damn transporter 100 years before Kirk and McCoy, it should had been all shuttles, and a rather big assortment of big, beefy shuttles at that. Smaller XV-30s and the like than the oddly small miracle craft that clamped awkwardly to the ship.
Voy landing always got an eyeroll from me. Take those legs out and put more space for dilithium crystals or replicator feedstock.
