Suddenly thought of this experimental ship with pump-jet propulsion. Figure 1 is the 2000-ton class experimental ship "Hai Kui 1", equipped with four domestically produced 16PA6STC diesel engines, using a 4-engine-4-pump drive layout, with a speed of 32 knots, and the output power is comparable to that of the 054A frigate, but it should be noted that the 054A is a 4000-ton class vessel.
Figure 2 is a 1500-ton class maritime police law enforcement patrol ship currently being outfitting at a shipyard in East China. It also uses four pump-jet propulsions. It is reported that the order for this type of maritime police ship is 10 vessels, built simultaneously by two shipyards.
The maritime police need such fast, maneuverable professional maritime police ships to gain an advantage in close-range combat. They also need high self-sustaining capability to ensure continuous maritime law enforcement. This task is not suitable for the 052D, while the 056 is barely suitable, and although the 022 has a good response capability, the navy is the navy, and its focus is different from that of the maritime police.
