Your industries can't even supply artillery and basic equipment to Ukraine, at least nowhere at the level needed to win the war. This is well-known. European leaders have been harping on the need to upgrade capacities.
So, newsflash: sorry, your military industry isn't up to par yet. The potential is there. Many of the technologies are there. The actual support and capacity to make the most out of that potential is lacking.
This isn't in any way a controversial opinion. The reality on the ground with constant shortages and European leaders themselves acknowledging the military industry needs more support is well known.
Europe's euro fighter jet is and was a very respectable fighter. With the shift towards stealth with the latest generation, it may be falling behind in key areas but still a good air craft. Developing a jet is a huge, huge undertaking and arguably Europe's resources could be spent better elsewhere rather than trying to develop an F35/F22 competitor.
Europe does have industrial and military capacity issues. This is well known and European leaders are among the quickest to point it out. No idea why the guy above wants to bury his head in the sand on that.
The biggest issues are arguably fragmentation and tepid political/societal support. Europe has various strengths but work is needed to make the most out of their potential.
