Germany is the pinnacle of engineering. If they want they can do it. French and british technology are inferior to Germany. Dont forget we are still not capable of building AIP submarines or Leo tanks. Are we capable of building a car like mercedes including its engines?
Iris-T missile systems that consist of air to air, surface to air are built by mainly German technology behind it. Namely DIEHL defence Systems.
Rheinmetal for artillery systems,
MTU /RR engines for marine use and heavy armoured vehicles,
MTU aero engines (derived from old BMW aero engines) that part produces EJ200 engines for Typhoon jets with RR help. but they are the people that first developed Blisk technology for compressor blades used first in ej200 engines,
Mbda Germany for missile systems,
Airbus Germany building Typhoon jets,
Leopard tanks,
AIP submarines,
RAM point defence systems’ missile production,
Naval ships
Are just some of the top end German military achievements. Almost all of the above are combat proven in one way or another.
But in aerospace they are behind both France and UK . However can catch up quickly if given the chance.
