“Zipline plans to conduct high-volume flight tests this year [2023] involving more than 10,000 test flights using about 100 P2 aircraft, with first customer deployment to follow.”

Zipline has never published a 2023-specific P2 test-flight count; by November 2025 it cited more than 150,000 physical P2 test flights in the US, but the first commercial P2 delivery did not occur until January 2025, well after the 'shortly after' timeline implied in 2023.
