Lockheed Martin Conducts Aerial Refueling Test

Lockheed Martin announced today that short takeoff/vertical landing (STOVL) variant of the Lockheed Martin F-35 Lightning II stealth fighter has become "The first F-35 to complete an aerial refueling test using the Navy- and Marine Corps-style probe-and-drogue refueling system".

Headquartered in Bethesda, Md., Lockheed Martin is a global security company that employs about 146,000 people worldwide and is principally engaged in the research, design, development, manufacture, integration and sustainment of advanced technology systems, products and services.
"The F-35 program is on the cusp of a tremendous expansion in flight test as a large number of new aircraft enter the test fleet this year and early next year," said Dan Crowley, Lockheed Martin executive vice president and F-35 program general manager. "This milestone will help ensure that we fill the pipeline between Fort Worth and Pax River with F-35s and maintain our flight-test tempo."
During Thursday's flight, the F-35B designated BF-2 (the second STOVL flight test aircraft), began a series of tests in which fuel is uploaded into the aircraft at 10,000, 15,000 and 20,000 feet, at speeds ranging from 200 to 250 knots.
The refueling mission also marked the first time a Lockheed Martin KC-130J tanker has been used to refuel an F-35.
As the company explains, probe-and-drogue refueling employs a flexible hose that trails from the tanker aircraft. The basketlike drogue at the end of the hose connects to the receiving aircraft's probe, which, in the case of the F-35, resides on the right side of the forward fuselage and retracts when not in use. The U.S. Navy, Marine Corps and the air forces of many other countries use the probe/drogue system, while the U.S. Air Force refuels its aircraft via a rigid flying boom that inserts into a receptacle on the receiving airplane.
The Lockheed Martin F-35 and F-22 are 5th generation fighters, characterized by a combination of advanced stealth with supersonic speed and high agility, sensor fusion, network-enabled capabilities and advanced sustainment. The three F-35 variants are derived from a common design, are being developed together and will use the same sustainment infrastructure worldwide, bringing economies of commonality and scale.
Lockheed Martin informs that it is developing the F-35 with its principal industrial partners, Northrop Grumman and BAE Systems. Two separate, interchangeable F-35 engines are under development: the Pratt & Whitney F135 and the GE Rolls-Royce Fighter Engine Team F136.
