InSWTOR the Sith Empire uses ship and uniform designs similar to those of the Galactic Empire in Episodes 4-6. But in Episodes 2 & 3 and the animated series we see the new clone-based Republic military using these same designs.
Did Chancellor Palpatine do this deliberately, thinking that nobody in this distant future would recognize these ancient Sith designs? Did Obi-Wan and Yoda look at these ships and think "Hm, interesting, I wonder where these designs came from" as they went about the business of fighting the separatists?
Or did some droid at the start of the Clone Wars just open up Encyclopedia Galactica and randomly pull up "Pattern #1247151 for Starships in the Billion-Ton Range", and "Uniform Pattern #14123114 for Galactic Empires That Used to be Republics"?
The Sith Empire of this time will eventually be defeated, and it's millions of citizens will become citizens of the Republic. And since this happens, it's not unlikely the Republic began using technology from the Empire to, perhaps, rebuild their fleet, or at least examine the designs and coming up with improvements on them. The dagger shape of Imperial ships may have been an efficient design.
Why wouldn't they exploit the technology of their defeated enemy? They used ancient Mandalorian designs (Kandosii-type Dreadnaught) to build the Dreadnaught-class Cruiser, in use during the Clone Wars. Another defeated enemy.
The Star Wars Extended Universe, despite taking place in an entire galaxy, has always been ludicrously small when it comes to things like this, and this game is no exception. Millions of planets, and where do we visit? Hoth, Tatooine and Taris. Thousands of corporations, and who inevitably designs the ships for each incarnation of the Empire? Sienar Fleet Systems. Billions of people living on Alderaan, and who do run errands for and/or slaughter? House Organa.
Despite the futuristic setting, technological stagnation has also been a long-running hallmark of the EU. We're several thousand years before ANH, and yet nearly every race in the galaxy seems to be at exactly the same point in their technological evolution that they are in the original films. So yes, the ships look the same. So does everything else, if you look closely. It's not this game's fault, so much as a bizarre and silly quirk of the Expanded Universe generally, to which the game is being faithful.
The Battle of Ruusan. The remaining Sith are exterminated on Ruusan, with the exception of Darth Bane, who starts a new Sith Order with only one master and one apprentice at a time (this is known as the Rule of Two). Each subsequent Sith would bear the title Darth, with few exceptions. The Senate passes the Ruusan Reformation, setting the year of the Battle of Ruusan to the year zero.
The reason the old design is in this time frame and in the movies time frame as far as ships go is that when a rebel army decides to over throw a government they take what they can get. Prime example of this is look at Afgan/Iraq/Pakistan/ect all these countries use old AK-47's for small arms. In fact if you spent any time collecting these (god knows I have) you'll find different types from different countries. For example we've confiscated some from China and Russia.
So in short Rebel armies will take any thing they can buy with what little money they have to fight. Also in this time period I'm sure that the republic uses Mon Cal Shipping Yards (or what ever the name of the ship building company is that produced the hammerhead design as well as the frigates in the original movies) as it's primary source of space tech, and in the original movies they where the chief supplier of ships for the Rebels since they did not join the Empire and split off to help the Rebels.
Its a scifi fantasy universe, it doesn't have to make any kind of sense whatsoever. If this was truly hard scifi with a thriving corporate sector and countless competing cultures then this kind of technological stagnation would be impossible.
It wouldn't be impossible. As someone who makes very well-informed posts, the reason there's technological stagnation is they've hit a sort of technological plateau. There hasn't been any need to make things "better".
They can already travel from one end of the galaxy to another in a reasonable time due to hyperdrive. They already have shields that can withstand a fair amount of punishment (although, I don't think anything ever explains with Sith/Imperial ships have external shield generators, and Republic/Rebel ships use internal), weapons are effective enough, etc. etc.
It's why both sides are making so many "doomsday" weapons. There just wasn't anything else they could really do. Even further into the series nothing changes much. They've simply tapped everything they can think of, and the only advancements they make is changes in design or use of material.
I think the problem we perceive with SW tech is that we inevitably compare it to our current level of technology, and when today we are in the brink of nano-machines, anti-matter, mutiverses and whatnot, as well as practical deadly and highly accurate intelligent weapons systems... SW ends up looking a somewhat backward place.
In response to the original poster: When Chancellor Palpatine formed the Grand Army of the Republic in 21 BBY, the Republic had been without a military for about 1,000 years (with the believed eradication of the Sith) so the choice of what style to go with was purely open to him and the Senate. As far as efficiency, the old Sith ship designs may have been best, while the Republic Army's armor was the best in that category. This principle holds true in real-world today as the US GI M-1 Helmet's design is based off of the German Helmets of WWII. In-Universe, we see the Republican Guard's uniforms slowly evolve to the Stormtrooper format, but the officer's uniforms aren't seen until much later, and even Moff Tarkin's uniform as he's overseeing the initial construction of the Death Star is still slightly different then his 0 BBY version. As for the Rebel Alliance's ships, until the Mon Calamari joined their cause, all of their ships were just "re-purposed" vessels that the "local" Planetary governments had original used for civilian purposes.
But yes, this is an In-Universe plot hole that Bioware created by associating this Empire with the one that would follow 3,000 years later. Even the accents were too far (as the Empire = British, Rebels = American concept was invented by Irvin Kirshner), and in fact causes huge holes for the non-exiled races (SPOILER: Kaliyo comments that my Chiss Imperial Agent wasn't born into the Empire, but still has the accent, when there is no logical explanation for this... nor is their a logical explanation on why the Chiss joined the anti-alien Sith Empire).
And to the guy who brought up "old AK-47's" technically most of them are not old, as they are still being manufactured, nor are they to be solely associated with "the rebels and pirates" across the globe, in fact about 90% of the world's governments use the 47 for their military, the other 10% either use Germany's Hechler & Koch's answer to the 47, and the US, which is the ONLY country to use the M-16 (why? because it's a piece of crap... even the terrorists, gangsters, drug lords and rebels don't want it).
it IS a very efficient design, it has the maximum amount of turrets able to fire at the enemy at all times so long as you keep your enemy in front of you or in worst case off to the side while maintaining a small profile. the only downside is you are completely exposed from the direct backside, not really a problem while on the offensive.
It's not really clear, they just ended up vanishing from the galaxy for the most part. It's possible that the bloodlines of the purebloods have only become a mere trickle... and possibly entirely eradicated with Bane's radical change in philosophy toward the way of the Sith.
