Which helicopter has the higher maximum airspeed?

Explanation:
Maximum airspeed comes from the balance of thrust, rotor efficiency, and drag, all shaped by engine power and airframe design. The HH-60 Jayhawk can reach about 180 knots because it has a more powerful engine and airframe built for higher-speed performance. The HH-65 Dolphin is smaller and optimized for efficiency and handling, with a lower maximum around 150–165 knots. So the Jayhawk achieves the higher maximum airspeed.
