Lockheed Martin F-35 Lightning II

Lightning II

The Lockheed Martin F-35 Lightning II consists of a family of single seats, single engine and it’s main role as a stealth multi-role fighters under development to undergo ground attack, reconnaissance and air defense missions.

The Lockheed Martin F-35 was designed to be the ultimate answer to the future multi-role fighter requirements. Built in 3 variants, the manufacturer could build over 3,000 of these aircraft, with a high production rate designed to minimize costs. But, as the testing continues on the aircraft, questions mount as to whether the Lightning II will give a promising delivery.

The F-35 redefines fighter aircraft, surpasses all expectations and is getting progressively cheaper. Though some experts say that the F-35 is fundamentally flawed on several levels, over budget, performing poorly and already proving that it cannot meet all promises that have been made.

The F-35 offers a wide range of advanced technologies to meet a number of mission roles. Multiply this by 3 variants and a range of requirements, the result would be a very complex aeroplane. The Lightning II's cockpit on the other hand is nothing short of revolutionary. A large liquid-crystal color display dominates the cockpit. This aircraft has been designed to be extremely simple and user-friendly.

'Finger on glass' brings the pilot everything from navigation and threat warnings to target designation and ordnance display. The most amazing feature is the 80 x 20 in-touch-screen. Lockheed Martin preferring this approach for a quick decision-making compared to voice-control.
