Darth Maul's TIE precursor also had a hyperdrive as well.
Basically, the main issue for hyperdrives not being in every TIE is COST.
There were canonically 25,000 ISDs in the Imperial Navy. At a wing of 72 TIEs per ISD, thats 1.8 MILLION TIEs alone.
The Empire at it's height had about a million worlds or systems. If we assume the same distribution for government structures as in the USA:
(https://www.statista.com/statistics/241 ... tion-size/)
Code: Select all
1m or more 10 0.0513%
500 to 999k 26 0.1334%
250 to 499k 51 0.2616%
100 to 249K 223 1.1439%
50 to 99K 465 2.3852%
25 to 49K 735 3.7702%
10 to 24.9K 1,574 8.0739%
Under 10K 16,411 84.1806%
Total 19,495 100.0000%
1 million times 15.8 percent equals 158,000 Wings and 11.37 MILLION TIEs.
Now, this is a simple analysis; we'd have to figure out how many TIE Wings a top grade world like Coruscant would get (a lot more than just 1), and figure out the contribution of the Imperial Army (Army wings are only 4 squadrons) Garrisons; but it provides a lower bound.
Then there's the scores of miscellaneous TIEs on:
Space Stations (2 to 3 squadrons -- 24 to 36 TIEs)
Nebulon B Frigate (2 squadrons - 24 TIEs)
etc.
It's plausible to figure that there are at least 20~ MILLION TIEs in the Galactic Empire at it's height.
When you have that many, cost and efficiency become main drivers -- an analogous situation would be the early Vietnam stuff:
UH-1 HUEY Cost: $300,000 in 1969
Cost to add Self Sealing Tanks: $10,000 (3% of total helicopter cost)
Link
We know this because the USAF didn't lose Hueys to fuel fires since they had all of their Huey's equipped with self sealing tanks and cited that cost.
So it's easy to see how the vast majority of TIEs built are simple, rugged craft designed for local patrol duties simply because of cost.
