A V-280 in flight with rotors tilted to hover configuration. The V-280 is designed for a cruising speed of 280 knots (320 mph; 520 km/h), hence the name V-280. It has a top speed of 300 knots (345 mph; 556 km/h), a range of 2,100 nautical miles (2,400 mi; 3,900 km), and an effective combat range of 500 to 800 nmi (580 to 920 mi; 930 to 1,480 km).
