Lockheed Martin F-35 STOVL Variant Flies Supersonic
"For the first time in military aviation history, supersonic, radar-evading stealth comes with short takeoff/vertical landing capability," said Bob Price, Lockheed Martin's F-35 U.S. Marine Corps program manager. "The supersonic F-35B can deploy from small ships and austere bases near front-line combat zones, greatly enhancing combat air support with higher sortie-generation rates." The F-35B will enter service for the Marines, the United Kingdom's Royal Air Force and Royal Navy, and the Italian Air Force and Navy.
The supersonic milestone was achieved on the 30th flight of the F-35B known as BF-2. U.S. Marine Corps pilot Lt. Col. Matt Kelly climbed to 30,000 feet and accelerated to Mach 1.07 in the off-shore supersonic test track near Naval Air Station Patuxent River. Future testing will gradually expand the flight envelope out to the aircraft's top speed of Mach 1.6, which the F-35 is designed to achieve with a full internal weapons load of more than 3,000 pounds. All F-35s are designed to launch internal missiles at maximum supersonic speed, as well as launch internal guided bombs supersonically. During the flight, Kelly accomplished 21 unique test points, including several Integrated Test Blocks to validate roll, pitch, yaw and propulsion performance.
BF-2 is the third F-35 to achieve supersonic flight. Two F-35A conventional takeoff and landing variants also have broken the sound barrier.
The F-35 program has about 900 suppliers in 45 states, and directly and indirectly employs more than 127,000 people. Thousands more are employed in the F-35 partner countries, which have invested more than $4 billion in the project. Those countries are the United Kingdom, Italy, the Netherlands, Turkey, Canada, Australia, Denmark and Norway.
Three F-35 variants are under development – the F-35A CTOL variant to replace U.S. Air Force F-16s and A-10s, as well as aircraft employed by seven allied nations; the F-35B STOVL variant to replace U.S. Marine Corps AV-8B Harriers and F/A-18s, U.K. Royal Air Force and Royal Navy Harrier GR.7s, GR.9s and Sea Harriers, and Italian Harriers; and the F-35C carrier variant to replace U.S. Navy F/A-18s.
The F-35 Lightning II is a 5th generation fighter, combining advanced stealth with fighter speed and agility, fully fused sensor information, network-enabled operations, advanced sustainment, and lower operational and support costs. Lockheed Martin is developing the F-35 with its principal industrial partners, Northrop Grumman and BAE Systems. Two separate, interchangeable turbofan engines are under development: the Pratt & Whitney F135 and the GE Rolls-Royce Fighter Engine Team F136.
Headquartered in Bethesda, Md., Lockheed Martin is a global security company that employs about 136,000 people worldwide and is principally engaged in the research, design, development, manufacture, integration and sustainment of advanced technology systems, products and services. The Corporation reported 2009 sales of $45.2 billion.
