Background
The absolute latest in American manned fighter aircraft, Lockheed Martin's F-35 Lightning II is slated to replace aging F-16, F-18, and AV-8B aircraft in the lightweight fighter attack role in the US Air Force and US Navy in the next several years. The land-based F-35A will replace the F-16, the vertical-takeoff F-35B will assume the Harrier's role, and the carrier variant F-35C will take over for the F/A-18. Several other nations, including the United Kingdom, are expected to purchase variants of the F-35 for their air arms. This fifth-generation fighter employs many advanced features, including low-observable (stealth) technology, to ensure its effectiveness in the 21st Century combat environment.
