EU had high thrust low bypass afterburning turbofan engines back in the day (M53, Spey, Olympus used on the Concorde etc.). It is spurious to claim that RR (even if we are not sure about Safran) does not have the technical capabilities today to make a F119 / WS15 / AL51 peer - it might take some time but RR has the capabilities. The Trent series for civilian aircrafts all boast significantly larger core than any military turbofans. RR was also a key contributor to the F120 / 136 programs and has been running its own ACE program. EJ200 is technologically comparable to F119 even (just on a smaller core, but RR has no problem making significantly larger cores than even F135 as you see with the Trents) and if you throw enough money at RR it can be developed into the EJ270 with similar thrust level to earlier F110s / AL31s.The EU does not have high thrust engines. Only the United States (F135, F119, F110), China (WS-15, WS-10), and Russia (AL41F1) have military high thrust engines in the world.
Many countries, such as France, the United Kingdom, Germany, Spain, Japan, South Korea, and others, have attempted to develop high thrust engines, but ultimately failed. Türkiye and India are still trying to enter the track.
We can summarize the reasons for the failure of high thrust engine projects in various countries.
Firstly, it requires top-level technological capabilities and a complete industrial ecosystem. It requires top-notch materials science, such as the manufacturing of single crystal blades, ceramic matrix composites, and other top-level materials. It also requires the ability for precision manufacturing and assembly. It also requires the system integration capability of hundreds of technical units including aerodynamics, thermodynamics, structural strength, etc. It also requires expensive and scarce facilities such as high-altitude platforms to conduct tens of thousands of hours of complete machine experiments.
Secondly, developing a high thrust engine requires a significant long-term investment of funds. Usually, an annual investment of over 2 billion US dollars is required, and a project typically lasts for more than 20 years. For example, the United States has invested over $100 billion in high thrust engine projects over the past 50 years.
Thirdly, due to the enormous investment of funds and time, the development process is very painful and unproductive, so the developing country needs a stable environment and national strategy that transcends economic and political cycles. Cannot be interrupted due to economic crisis or government changes.
If Turkey could successfully develop high-thrust engines in the short term, it would be a proud miracle indeed. But our current skepticism is logical. Because if Turkey really had such strength, it should be the British who bought fighter jets from Turkey, not the other way around. The British have already failed in the high-thrust engine, and Britain has failed three times (BS100, RB106, TSR-2).
What Europe currently lacks are funding and use case for a low bypass high thrust afterburning turbofan but RR is still likely the third best turbofan OEM on the whole behind only GE / PW. With more funding and time I am sure China will leapfrog RR (and even the Americans) but for now RR is still slightly ahead.
