The Pixiu submarine has a range exceeding 16,000 nautical miles. Based on this distance, it could easily reach the southern tip of China, or even make a round trip to the northeastern waters. However, in reality, this is impossible in combat. This is because that's a theoretical value for a submarine navigating at an economical speed on the surface. In actual combat, chasing and searching for the enemy requires navigating circuitous routes, consuming large amounts of diesel fuel.
Therefore, in the event of combat, the Pixiu's remaining time in the Beibu Gulf would be very limited. Thus, a supply ship is needed, making the PJP (the cargo ship) crucial for providing support. Furthermore, the PJP also has the mission of transporting five to six hundred tons of explosives.
