\(\Huge\color{darkred}{Lockheed~F-117~Nighthawk}\)


American Single subsonic tactical strike aircraft unobtrusive firm Lockheed Martin, is designed for covert penetration through the enemy's air defense and ground attack strategically important military facilities (missile bases, airfields, command posts and communications, and so on. n.).

The first flight made June 18, 1981. Produced 64 units, the last serial copy was delivered the US Air Force in 1990.
F-117 quite successfully applied in a number of military conflicts. In mid-2008 aircraft of this type have been completely decommissioned, mainly because of adopting the F-22 Raptor.
Once the project was developed by the F-117 ground-based - F-117A. Offered by Lockheed projects F-117B, F-117N (carrier-based) and the A / F-117X were rejected.
The official name of the F-117 in the US Air Force - "Night Hawk» (Night Hawk - Eng. Nighthawk), though there are also fused writing "Nighthawk". According to the notation in the military aircraft the US, the letter F is assigned to the fighters. The reason why "Night Hawk" has been classified as a fighter and was in service with fighter squadrons, remains unclear; Contrary to popular culture in the way of "stealth fighter» (Stealth Fighter), F-117 is a tactical strike aircraft (bomber / attack aircraft) and was never intended to perform destructive tasks. A similar situation occurred with the tactical / strategic bomber F-111, also wore "fighter" designation.
The design of the aircraft based on stealth technology. The aircraft itself is built on the aerodynamic configuration "flying wing" with a V-tail. It is not typical for subsonic aircraft swept wing (67,5 °) with a sharp leading edge, straight lines outlined wing profile faceted fuselage formed trapetsevidymi flat and triangular plates are arranged in such a way relative to each other to reflect electromagnetic waves in the direction of the radar the enemy. This form of the plane, which was built on the concept of the "plane-reflectors", called "faceted" (from the French. Facette - face). Located over the wing on both sides of the fuselage flat air inlets have longitudinal walls of radar absorbing materials. Part of the cold air flow is separated at the inlet of the air intakes and engine bypass enters into Escaped flat wing nozzle having dimensions 165 x 25 cm, the lower heat-absorbing panels which are covered with ceramic tiles, which considerably reduces the IR visibility of the aircraft. The plane has no external suspension, all weapons placed inside the fuselage.
The contours of the slits formed in the joints of the canopy to the fuselage, landing gear bay doors and arms have a sawtooth shape, which also provides effective scattering of electromagnetic energy and prevents its direct reflection in the direction of the enemy's radar antenna Transceiver.
The design of the aircraft widely used polymer composite materials and Radar-absorbent material. In proportion to the airframe metal alloys have only 10 percent by weight. As a result of these measures, the effective surface scattering plane when irradiated locator front has been reduced, according to some estimates, up to 0,025 m², which is several tens of times less than conventional aircraft EPR similar size.
Faceted shape of the fuselage and wing profile unusual significantly degrade the aerodynamic characteristics of the aircraft. In the process of designing a compromise was reached in which the requirements of low radar visibility prevailed over the requirements of aerodynamics - the aerodynamic quality of the aircraft is 4 (this is a bit better than the Space Shuttle Orbiter), as a result it is impossible to fly at supersonic speeds, limited range decreases combat load and maneuverability.
It should be noted that, despite such radical solutions, designers failed to reach the ultimate goal - to build an airplane, invulnerable to the enemy. Firstly, due to the deterioration of aerodynamics the F-117 was poorly protected from the attacks of enemy fighters, if they could find it. Secondly, by the design ideas could reduce visibility only to a certain limit, and did not provide a very low ESR for radar systems, in which the receiver and transmitter have been carried on different points. For example, when raids on Yugoslavia, the F-117 was shot down by a modernized system S-125 3rd Battery 250th Air Defense Brigade.
The aircraft is controlled by FBWCS with fourfold redundant control channels. Since the F-117 is unstable in pitch and yaw, used automatic system sustainability. Since 1991, in addition to its installed autothrottle.
On the plane is not installed radar. Except for the laser target illumination, all aiming and navigation passive. For guidance system is used infrared cameras for navigation - inertial system and a satellite navigation system receiver. Active EW systems do not.
Weapons bays - two-section, a length of 4.7 m and a width of 1.75 m, with a system of retractable racks. Types of weapons - two Guided bomb GBU-10 and GBU-27 caliber 907 kg. Installation of missiles AGM-88 HARM, AGM-65 «Maverick», atomic bombs B-61 or B-83 (two), GBU-15 bombs or container BLU-9 submunitions. The beam can be installed rails for AIM-9 «Sidewinder».
The existence of the aircraft the F-117 was first officially recognized November 10, 1988, when the Pentagon issued a press release describing the history of the aircraft and unveiled a retouched picture. The first public screening of two F-117 was held April 21, 1990. In 1991, after the Gulf War, "Night Hawk" was shown at the Paris Air Show.
Initially, all the F-117 were armed with 4450-th Task Force at the airbase Tonopah, Nevada, Tonopah Test Range Airport. In 1989, the group became part of the 37th Tactical Fighter Wing. In 1992, all aircraft were transferred to Holloman AFB in the 49th Fighter Wing. They are operated by the three squadrons: two combat (8th Fighter "black sheep", 9th Fighter "Flying Knights") and one training (7 Squadron combat training "Screaming Demons").
For the entire history of the F-117 aircraft, according to official data was lost 7 cars (just over 10% of the total built), including one F-117 was shot down in the fighting. "Nighthawk" flew a total of about 220 000 hours, ie the raid on the one loss was about 31 000 hours.
April 20, 1982 - F-117A (Ser. No. 80-0785), Lt. Col. Bob Raydenauer (Bob Ridenhauer) «Bandit 102". The plane crashed on takeoff due to incorrectly configured at the factory of flight control. The pilot did not have time to eject, was seriously injured and was decommissioned from the Flight of work.
July 11, 1986 - F-117A (Ser. No. 81-0792), Major Ross Malheyr (Ross Mulhare) «Bandit 198". The aircraft collided with the ground in the area of ??Bakersfield, California, during a night flight. The reason - the disorientation of the pilot, who had a small plaque on the F-117. Major Malheyr died.
October 14, 1987 - F-117A (Ser. No. 83-0815), Major Michael Stewart (Michael Stewart) «Bandit 231". The aircraft collided with the ground near Tonopah during a night flight. The reason - the disorientation of the pilot, who had a small plaque on the F-117. Major Stewart died.
August 4, 1992 - F-117A (Ser. No. 85-0801), Captain John Mills (John Mills) «Bandit 402". The plane caught fire during a night flight airbase near Holloman and exploded in the air. The reason - a mistake ground maintenance personnel for maintenance. Captain Mills safely ejected.
May 10, 1995 - F-117A (Ser. No. 85-0822), Captain Kenneth Levens (Kenneth Levens) «Bandit 461". The aircraft collided with the ground in the area of ??Zuni, New Mexico, during a night flight. The purported reason - pilot disorientation, who had a small plaque on the F-117. Captain Levens died.
September 14, 1997 - F-117A (Ser. No. 81-0793), Major Brian Knight (Bryan Knight) «Bandit 437". The aircraft was destroyed in the air and crashed into a building during an air show in Chesapeake, Maryland. The accident occurred due to technical reasons, which led to a loss of control by the pilot. On the ground, injured 4 people. Major Knight safely ejected.
US Air Force going to operate the F-117, at least until 2018 , but the lack of money for the purchase of new multi-role F-22 fighters forced them to begin the process of removing the "Night Hawk" with weapons much earlier. Officially, it was announced in autumn 2006. In the same year the school was closed pilot training F-117, its last edition was held on October 13
The first ten F-117 were retired in December 2006. By March 2008, the US Air Force continued to operate 15 aircraft of this type The formal procedure of removal from service ended on April 22 of that year, when four F-117 was the last time up in the air, having made the flight to the airbase Tonopah
