The CH-53K King Stallion achieved its first external lift flight, successfully carrying a 12,000 pound external load. As testing ramps up both of the current flying prototypes will be exercised to expand the external load envelope. Initial external payloads weighing 12,000 pounds will be flown first in hover and then incrementally to speeds up to 120 knots. The aircraft will then carry 20,000 and 27,000 pound external payloads. | Sikorsky
