F-22 Raptor 1st Fifth Generation Stealth Fighter

Mission
The F-22 Raptor is the Air Force's newest fighter aircraft. Its combination of stealth, supercruise, maneuverability, and integrated avionics, coupled with improved supportability, represents an exponential leap in warfighting capabilities. The Raptor performs both air-to-air and air-to-ground missions allowing full realization of operational concepts vital to the 21st century Air Force.

B-2 Spirit Stealth Bomber

Northrop Grumman is the prime contractor for the US Air Force B-2 Spirit stealth bomber. The B-2 is a low-observable, strategic, long-range, heavy bomber capable of penetrating sophisticated and dense air-defence shields. It is capable of all-altitude attack missions up to 50,000ft, with a range of more than 6,000nm unrefuelled and over 10,000nm with one refuelling, giving it the ability to fly to any point in the world within hours.


21 B-2s have been delivered to Whiteman Air Force Base in Missouri, the first in December 1993. In the first three years of service, the operational B-2s achieved a sortie reliability rate of 90%. An assessment published by the USAF showed that two B-2s armed with precision weaponry can do the job of 75 conventional aircraft.


The aircraft carries all its weapons internally and is fitted with two separate weapons bays in the centre of the aircraft. The B-2 has the capacity to carry up to 40,000lb of weapons, including conventional and nuclear weapons, precision-guided munitions, gravity bombs and a range of maritime weapons.

F-117 Night Hawk



The F-117 Nighthawk stealth fighter attack aircraft was developed by Lockheed Martin after work on stealth technology, and the predecessor test demonstrator aircraft, Have Blue, was carried out in secret from 1975.The Nighthawk is the world's first operational stealth aircraft. The first aircraft was delivered in 1982 and the last of the 59 Nighthawks procured by the US Air Force was received in 1990.The F-117A aircraft is also known as the Frisbee and the Wobblin' Goblin. The mission of the aircraft is to penetrate dense threat environments and attack high-value targets with high accuracy. Nighthawk has been in operational service in Panama, during Operation Desert Storm, in Kosovo, in Afghanistan and during Operation Iraqi Freedom.The aircraft can carry a range of tactical fighter ordnance in the weapons bay, including BLU-109B low-level laser-guided bomb, GBU-10 and GBU-27 laser-guided bomb units, Raytheon AGM-65 Maverick and Raytheon AGM-88 HARM air-to-surface missiles.
