Russian Cloning
You really do not understand how it works...
US companies are constantly hacked by Russia/China or both at same time... stealing valuable production secrets...
looks like it backfired this time... as it did when the Russians (then known as Soviets) cloned the b-29 bomber to make the TU-4
( great story how exact the copy was: https://tu-95.net/soviet-b-29-clone-the-tupolev-tu-4/ )
