Virginia has been made in double digits already and has far superior track record. Yasen barely has one because they barely exist. One completed and one in tests. That's it.

Are you clinging to paperwork here?
Not that it matters because USN has far stricter safety regulations.
They haven't lost a sub since USS Scorpion and that was in 1968.
You don't get it.
Say there are order for two truck , one for 5 tons of load capacity, the other is for 10 tons of load capacity, all other parameter the same.
Now, company A deliver the truck with 5 tons certified, but the other fail the delivery , and provide only a truck with 8 tons of load capacity.
The second truck failed the order specification, but does it means it is inferior compared to truck 1 with 5 tons of load capacity ?
Or it means it superior compared to the other truck, but not achieved the design parameters?
Same for safety, it is easy to operate a lift with extreme safety, all that it takes is to use it no more than 10th of design load.
Now, operating it closer to the design load ( diving it deeper /going faster) decrease the safety margin.
