Tianran Xu pointed out that it is challenging to determine whether the engine is merely for display, an early development model or a more serious piece of technology - this type of gas turbine is relatively large and has powered USSR's large surface combatants, but he's uncertain if DPRK possesses the capability to reverse engineer such a complex engine. He emphasized the complexity and durability required for large gas turbines, especially since they need to work reliably for extended periods or require significant maintenance in naval ports.
