F-117 Nighthawk

The Lockheed F-117 Nighthawk is a stealth ground attack aircraft formerly operated by the United States Air Force. The F-117A's first flight was in 1981, and it achieved Initial Operational Capability status in October 1983.[1] The F-117A was "acknowledged" and revealed to the world in November 1988.[4]

A product of the Skunk Works and a development of the Have Blue technology demonstrator, it became the first operational aircraft initially designed around stealth technology. The F-117A was widely publicized during the Persian Gulf War of 1991.

The Air Force retired the F-117 on 22 April 2008,[2] primarily due to the acquisition and eventual deployment of the more effective F-22 Raptor[5][6] and F-35 Lightning II.

F-35 Lightning II

The Lockheed Martin F-35 Lightning II is a fifth-generation, single-seat, single-engine, stealth-capable military strike fighter, a multirole aircraft that can perform close air support, tactical bombing, and air defense missions.[6] The F-35 has three different models; one is the conventional takeoff and landing variant, the second is short takeoff and vertical-landing variant, and the third is a carrier-based variant.

The F-35 is descended from the X-35, the product of the Joint Strike Fighter (JSF) program. Its development is being principally funded by the United States, with the United Kingdom and other partner governments providing additional funding.[7] It is being designed and built by an aerospace industry team led by Lockheed Martin with Northrop Grumman and BAE Systems as major partners.[7] Demonstrator aircraft flew in 2000,[8] with the first flight on 15 December 2006.
