I hear that often, not only about Saudi Arabia but many Muslim countries in general. I mean the idea that Muslim countries did not want to focus on hard sciences and domestic industries decades ago. They all wanted but vast majority (if not all) could not on a large scale until the past 2-3 decades.
Saudi Arabia have been doing great work in the past decade or so. Probably before that as well. It kicked off during the reign of King Abdullah. Nowadays Saudi Arabians are some of the most educated not only in the Muslim world but the world as a whole. In particular the women. You can't survive without it nowadays, the locals are competing with some of the brightest minds from across the Muslim world/West as well. What we have seen so far is only the very beginning and the Saudi Vision 2030 will give a good picture of which direction the country is truly going towards long-term. There is reason to be very optimistic as things stand right now IMO.
I don't think that it was possible or realistic to focus on indigenous tech as far back as 50 years ago. Too low a population, not strong enough local talent pool nor economy. Even though Saudi Arabia underwent gigantic changes and developments on all fronts in the 1960's and 1970's. It would have been a too big ask for them to also go all in on hard sciences given that no Muslim state was able to do so back then. Even more if yo tak the low domestic population into account, the economy and everything that I outlined above.
Saudi Arabia should go for the option which will have the greatest amount of tech transfer and local production (50% is a minimum as stated and state policy dictates that nowadays too), combined with the best overall tech, most secure option "politically" and which will have the best benefits down the road in terms of future cooperation and independence (no pressure from external sources - such as the USA for instance).
In that case China would be the preferred option IMO. This would also be in line with Saudi Arabia's strategic relationship with China which China already helping them with their domestic ballistic missile program, uranium mining, mineral mining, UAV's and other strategic projects. China is also their largest trade partner by far etc.
Remember, Saudi Arabia's navy is a bit underwhelming compared to their air force, land forces, missile force (offensive and defensive) etc. Which is a bit strange given the large coastline of Saudi Arabia (on two fronts even) and their enormous oil and gas reserves and mineral wealth as well as busy shipping ports and some of the most busy trade routes trespassing the country directly. Saudi Arabia borders 3 of the most busy sea trade routes in the world. All this requires a strong navy so this was long overdue. Moreover if you consider that Saudi Arabia is probably never leaving Yemen and I would not be surprised if the Sunni parts of Yemen (with direct access to the Arabian Sea) would join KSA (rich in resources and not too overly populated unlike Western Yemen = less of a burden) so another reason for a strong navy, but that is for another discussion.
I believe that what Saudi Arabia really lacks are advanced submarines..
Royal Saudi Naval Forces
Almost 21 000 Serve in the fleet and 4,000 soldiers in the Marines..
There is a huge and extensive naval infrastructure..
In the Saudi Naval Forces, the main pillars for measuring the development of the navies will be gathered, which are submarines - destroyers - stealth frigates - anti-submarine aircraft - helicopter carriers - jet aviation - advanced corvettes - air defense systems such as the Aster 30 and Aegis..
What is coming next to the Saudi Navy is wonderful in every sense of the word..
The new Korean frigate dedicated to Saudi Arabia "HDF-3800SA" has been announced, with a displacement of 3800 tons.
The frigate assigned to Saudi Arabia will be able to accommodate the MH-60R helicopter owned by the Saudi forces
The frigate will be able to perform anti-air, surface and anti-submarine warfare missions
and electronic warfare. The HDF-3800SA is based on the FFX Batch II (Daegu class) frigate.
which is currently in service with the Republic of Korea Navy (RoK).
Design improvements include the shape of the Hi-Bow body
Designed exclusively by Hyundai Marine Research Institute.
The frigate is made up of a complex of advanced Korean combat systems.
frigate armament
76mm “STRALES” (with guided ammunition) main gun, 16x K-VLS for K-SAAM, 2x Sylena Mk2 decoy launchers by Lacroix, 8x C-Star Korean anti-ship missiles, 2x triple torpedo launchers, 2x rockets launchers and a CIWS (on top of the helicopter hangar). The frigate can accommodate the new MH-60R helicopter of the Royal Saudi Navy. It is also fitted with a variable depth sonar..
Initially, it will be manufactured in the King Salman Complex for Maritime Industries
Because in their wing in the defense exhibition there is the same frigate..
It will be made by IMI, a Saudi company owned by Saudi Aramco, Lamprell plc, National Shipping Company and Hyundai Heavy Industries Ltd.
Aramco and Bahri own about 80% of the company, Hyundai 15%, Lamprell 5%,.
The Saudi version of the HDF-3800 frigate is the proposal submitted by Hyundai to the Saudi Navy's tender to purchase 5 frigates..
The memorandum of understanding between the Korean company and its strategic partner in Saudi Arabia, the International Company for Maritime Industries IMI, to cooperate in the manufacture of frigates, may give us a clear indication that they are the closest to winning the competition against the Spaniards and the French..
Naval News, which was a media partner to cover the exhibition, stated that one of the requirements of the tender is to invest 60% of the contract value in local Saudi companies..
According to the tender schedule, the contract will be signed in the second half of 2023 for five frigates with a displacement of 4000 tons, with a deal valued at 2 to 2.5 billion dollars..
Awesome news, the Navy explicitly needs a number of new frigates and ships
The Royal Navy has undergone an amazing transformation since the appointment of its new commander..
The Kingdom is also interested in the Spanish
NS4K SMART 4000
Navantia @NavantiaOficial reintroduced the NS4K SMART 4000 stealth design as a unique design revolution in the world of military and future naval industries at #WDS2022
, attracting strong attention from the Saudi Naval Forces..
