F-117 Nighthawk Stealth Fighter – We [RULE] The Night!

F-117 Nighthawk Stealth Fighter - We [RULE] The Night!

F-117 Nighthawk Stealth Fighter

F-117The F-117 Nighthawk Stealth Fighter was made famous for its role during the Persian Gulf War in 1991. She was the aircraft that fired the first shots of Desert Storm and lead the way into the most heavily defended city in the world at that time, Baghdad. With her stealth technology, she was easily able to penetrate enemy airspace undetected and strike her targets with laser like precision.

On the first night of the war, it was reported that the Lockheed F-117 Nighthawk hit 80% of their designated targets with zero combat losses. Later reports were scaled back to a 41–60% success rate which is still pretty impressive. The F-117 was the only aircraft that the coalition would risk over Baghdad because it was so heavily defended. Most of the optically aimed AAA and infra-red SAMs were located on the outskirts of the city making it possible for other aircraft to hit targets inside the downtown Baghdad area.

During the Gulf War in 1991, the F-117 logged in approximately 6,905 flight hours scoring direct hits on 1,600 high-value targets while flying 1,300 sorties in Iraq. She carried 500-2000 pound laser-guided bombs designed for hardened targets such as underground bunkers and aircraft hangers. Although the F-117 is designated “F” for fighter, she is a ground attack aircraft only and NOT a dogfighter.

The F-117 was specifically designed to be the world’s first invisible plane and defeat any enemy radar system. It is her unique design that made her stealth capabilities possible. Stealth technology has its advantages and disadvantages such as sacrificing performance for stealth. The F-117 Stealth Fighter is a ground attack aircraft that is NOT very maneuverable because of a high sweep wing angle of 50° degrees needed to deflect incoming radar waves.

Another disadvantage to stealth technology is the F-117’s speed and performance. This is due to lower engine thrust and losses in the inlet and outlet, a very low wing aspect ratio and a high sweep wing angle of 50° degrees as mentioned earlier. Because of these design considerations and no afterburner, the F-117 Nighthawk is limited to subsonic speeds. It is this revolutionary design that gives the F-117 a radar cross-section of about 0.001 m2 (0.0108 sq ft), which is about the size of a small bird on a radar screen.

Lockheed F-117 Nighthawk

Lockheed F-117 Nighthawk

The Lockheed F-117 Nighthawk was proposed by Skunk Works Director Kelly Johnson and his assistant Ben Rich. In the early 1970’s the United States Air Force (USAF) approached Lockheed with a stealth concept for a first strike aircraft. Kelly Johnson proposed a rounded design which he believed the smoothly blended shapes offered the best combination of stealth and speed.

Kelly’s assistant Ben Rich, proposed faceted-angle surfaces which he believed would provide significant reduction in radar signature and that necessary aerodynamic control could be easily provided with computer units. In May 1975, a Skunk Works report titled “Progress Report No. 2, High Stealth Conceptual Studies” showed why the rounded concept was rejected in favor of the flat-sided design proposed by Ben Rich. Although both concepts were revolutionary, the flat-sided design proved to be stealthier.

F-117 Nighthawk Cutaway

This highly unusual design makes the F-117 Nighthawk aerodynamically unstable in all three aircraft principal axes. Constant flight corrections need to be made by a fly-by-wire (FBW) flight control system to maintain controlled flight. Without this state-of-the-art fly-by-wire (FBW) flight control system. It would be impossible for pilots to fly the F-117. The F-117 is just too aerodynamically unstable!

Experienced fighter pilots were both shocked and amazed at the unusual design of the F-117 Nighthawk. One pilot was quoted as saying that stated that when he first saw a photograph of the F-117 Nighthawk, he promptly laughed and thought to himself that the F-117 clearly can’t fly. He was right in a sense because early stealth aircraft such as the F-117 were specifically designed for minimal radar cross-section (RCS) rather than aerodynamic performance.

On June 18, 1981, the first YF-117A, serial number 79-0780, made its maiden flight from Groom Lake (Area 51), Nevada. That’s only 31 months after the full-scale development decision was made. The first production F-117A was delivered in 1982 and operational capability was achieved in October 1983. The F-117A Nighthawk 4450th Tactical Group would be stationed at Nellis AFB, Nevada.

F-117 Top Speed

F-117 Stealth Fighter Flyby

The F-117 Top Speed is a modest Mach 0.92 (617 mph, 993 km/h) which is its maximum speed and cruise speed is at Mach 0.92. Because of the F-117’s design, she is not capable of super-sonic speeds. However, the F-117 Nighthawk’s lack of speed makes up for her invisibility to radar. Early stealth fighter designs were all about stealth, not aircraft performance.

The F-117 Nighthawk’s power-plant are 2 General Electric F404-F1D2 turbofans with 10,600 lbf (48.0 kN) each. She has a range of 930 nmi (1720 km) and a service ceiling of 45,000 ft (13,716 m). Wing loading is 67.3 lb/ft² (329 kg/m²) and the thrust to weight ratio is 0.40. The General Electric F404-F1D2 turbofans were a perfect fit for the F-117 Nighthawk and gave her maximum performance in spite of her unusual aerodynamic design.

F-117 Top Speed

In the early 1990’s, Lockheed proposed a new variant of the F-117 Nighthawk for the United States Navy (USN). This new variant would be suitable for carrier use and was dubbed the F-117N “Seahawk”. However, the United States Navy had no interest in the single mission capabilities of the F-117N “Seahawk”. The F-117N “Seahawk” would have differed from the F-117A Nighthawk in many different ways. The new variant would include a bubble canopy, reconfigured tail, a less sharply swept wing and elevators.

After the Navy shot down the F-117N “Seahawk” proposal, Lockheed submitted an updated proposal that included an a larger emphasis on the F-117N as a multi-role aircraft rather than just an attack aircraft. The new F-117B was a land-based variant that featured all of the F-117N capabilities. This variant was proposed to the United States Air Force (USAF) and the Royal Air Force (RAF).

The renewed F-117N proposal was also known as the A/F-117X. The F-117N nor the F-117B were ordered by the Royal Air Force (RAF) or the United States Air Force (USAF). These aircraft could be fitted with a new ground-attack radar system with air-to-air capability. She also featured optional hard-points allowing for an additional 8,000 lbs (3,600 kg) of payload. In this new role, the F-117N “Seahawk” and F-117B could carry AIM-120 AMRAAM air-to-air missiles.

F-117 Cockpit

The F-117 Cockpit was very spacious for pilots compared to traditional fighter planes. She featured ergonomic displays and controls making the pilots job so much easier with everything at their fingertips. One of the problems pilots faced was their limited field of view. It was somewhat obstructed by the design of the canopy with a gigantic blind spot in the rear. Since the F-117 Nighthawk was an attack aircraft and not a dogfighter, the lack of visibility was not a huge problem for pilots.

F-117 Cockpit

The avionics inside the F-117 Nighthawk were state-of-the-art at that time and the core of this magnificent aircraft. Even though she featured stealth technology to evade enemy radar, she relied on her quadruple-redundant fly-by-wire flight controls, sophisticated navigation and attack systems integrated into a digital avionics suite. No other aircraft in the world at that time featured an avionics package like this!

Take a look at the F117 Cockpit photo below and see what it looks like from a fighter pilots point of view. As you can see, the F117 Cockpit is roomier and the ergonomic displays and controls are right in front of the pilot. Just like other fighter planes, the control stick is right in between the fighter pilots legs with the throttle on the left. This cockpit configuration was extremely efficient for pilots and relatively comfortable on long flights as well.

The F-117 Nighthawk’s sophisticated navigation and attack systems navigate primarily by using GPS and high-accuracy inertial navigation. All F-117 Nighthawk missions are coordinated by an automated planning system. This automated planning system can automatically perform all aspects of an attack mission including weapons release and safely return to base. The F-117 Nighthawk could technically fly a mission without a pilot in command!

11 Little Known Facts About The F-117 Nighthawk – F-117 Is Still Flying

The Amazing Lockheed F-117A Nighthawk was a flying legend during her time and exceeded all expectations when the moment of truth arrived. She performed flawlessly in combat and proved to be the most valuable asset in the United Air Force’s inventory. Even though she wasn’t very fast, she was nearly invisible to radar making her the world’s first stealth fighter to enter service. She has paved the way for a new generation of stealth fighters with unimaginable capabilities.

There were a total of 64 F-117 Stealth Fighters built, 5 YF-117As and 59 F-117As. The F-117 Nighthawk exclusively saw service with the United States Air Force (USAF). The Royal Air Force (RAF) was offered to buy the F-117 Nighthawk during the Reagan administration but declined for reasons unknown. Each F-117 Nighthawk cost approximately $42.6 million USD (flyaway cost) and $111.2 million USD (average cost).

A Flyaway cost is the basic cost of production including the tools to make the aircraft. It does not take into account research and development and supplementary costs for support equipment, avionics and weapons systems. The F-117 Nighthawk developed from the Lockheed Have Blue program. The F-117 Nighthawk first entered service in October of 1983 and was retired on April 22, 2008 when she took her last flight.

B-2 Stealth Bomber – [UNCLASSIFIED!]

B-2 Stealth Bomber - [UNCLASSIFIED!]

B-2 Stealth Bomber

B-2 SpiritThe B-2 Stealth Bomber is the most advanced strategic bomber ever created! This amazing aircraft features low observable stealth technology that is specifically designed to penetrate any anti-aircraft defense system in the world! She is basically invisible and has a radar signature of a small bird.

The Northrop Grumman B-2 Spirit stealth capability comes from a combination of reduced infrared, acoustic, visual and radar signatures (Multi-Spectral Camouflage). This helps the B-2 evade various types of hi-tech detection systems that would be used to detect and direct attacks against the aircraft.

Inside the Stealth B2 Bomber Military Documentary HD – MUST SEE Video!

She also features additional reduction capabilities in its radar signature by the using various state-of-the-art radar-absorbent materials (RAM) which neutralize and absorb radar beams. The B-2 is also painted in a special anti-reflective paint which helps to reduce optical visibility during daylight flights. The contents used to create the anti-reflective paint is classified.

The undersides of the B-2 Bomber are painted a dark grey because of the high altitudes (50,000 ft or 15,000 m) she flies. At those high altitudes, the dark grey paint job blends perfectly into the sky above. It is rumored that the B-2 has an upward-facing light sensor that automatically alerts the pilot to reduce or increase altitude in order to match the ever changing illuminance of the sky.

The B-2 Bomber’s only vulnerability is visual interception at ranges of approximately 20 to 23 nmi (37 km) or less. This is why all production aircraft have a contrail sensor that alerts the pilot when he should change altitude. The original B-2 Spirit design had tanks for a contrail-inhibiting chemical. These tanks were scraped in favor of the contrail sensor which was developed for the production variation of the aircraft.

Northrop Grumman B-2 Spirit

Northrop Grumman B-2 Spirit

On July 17, 1989, the Northrop Grumman B-2 Spirit took to the skies for the very first time and made aviation history. The origin of the B-2 Spirit comes from several versions of flying wing aircraft such as the Northrop YB-49 and German Horten Ho 229. during the last days of World War II, the German Horten Ho 229 actually flew combat missions.

Although these aircraft proved to be capable aircraft, the Northrop YB-49 was scrapped due to technical difficulties and soaring costs. The German Horten Ho 229 was the first jet powered flying wing in aviation history! It amazes me that this aircraft did not continue to fly in Russian or Allied Air Forces after the war. The German Horten Ho 229 could be considered the grandmother of the B-2 Spirit.

B-2 Stealth Bomber Cutaway

The Advanced Technology Bomber (ATB) program began in 1979 and would end up costing approximately $44.75 billion US through 2004. There were a total of 21 B-2 Spirits built at a cost of $737 million each at flyaway cost. Each B-2 Bomber would eventually cost $2.1B US dollars. B-2’s first entered service January 1, 1997 and is still in service today. Due to the end of the Cold War, Congress purchased only 21 of the planned 132 bombers.

This was also due to the overall cost of the program and the astronomical operational costs. There are are currently 20 B-2’s serving in the United States Air Force today and plans to operate them until 2032. Only 1 B-2 has been lost and was destroyed in a crash shortly after takeoff in 2008. The crew did manage to eject safely. The B-2 Spirit is designed for all-altitude attack missions up to 50,000 feet (15,000 m).

She has a range well over 6,000 nautical miles (6,900 mi; 11,000 km) on one tank of fuel and more than 10,000 nautical miles (12,000 mi; 19,000 km) with a midair refueling. The B-2 bomber can deploy either thermonuclear or conventional weapons, such as sixteen 2,400 lb (1,100 kg) B83 nuclear bombs or eighty 500 lb (230 kg)-class (Mk 82) JDAM Global Positioning System-guided bombs. The B-2 also can also carry large air-to-surface standoff weapons in its stealth configuration.

B-2 Spirit Speed

B-2 Bomber Breaking The Sound Barrier

The B-2 Spirit Speed is not as fast as you may think. She flies just as fast as a conventional bomber. The B-1 Bomber and the Russian Tupolev Tu-22M were the only bombers capable of supersonic speeds. It was the development of the B-2 Bomber in the 1970’s that caused the cancellation of the B-1 Bomber which is also in service today. This is what eventually led to the program being canceled in 1977 after the B-1A prototypes were built.

The B-2 Stealth Bomber is a subsonic bomber which means she flies slower than the speed of sound. She does have an unclassified top speed of Mach 0.95 (550 knots, 630 mph, 1,010 km/h) at an altitude of 40,000 ft. This is just short of the speed of sound which is Mach 1. There is considerable debate among aviation enthusiasts that she is capable of supersonic flight. It she is capable of speeds above Mach 1, it remains classified.

B-2 Spirit Speed

The B-2 Stealth Bomber is powered by four powerful General Electric F118-GE-100 turbofan engines. The General Electric F118-GE-100 turbofan engines are internally mounted inside the body of the wings. These engines are rated at 77kN which provide a maximum gross take-off weight of 336,500lbs and a high subsonic speed. The General Electric F118-GE-100 turbofan engines have an exhaust temperature control system which minimizes thermal signature.

It is these magnificent engines that power the B-2 Bomber and give her unprecedented power with the ability to carry large payloads. With her stealth capabilities combined with these General Electric F118-GE-100 turbofan engines make her the deadliest air asset in the world. It is rumored that if there were hostilities among the nuclear powers. They would have no choice but to launch their missiles once the B-2’s takeoff in order to guarantee a strike of their own.

B2 Cockpit

B2 Cockpit

The B2 Cockpit is where the two person crew sits and where all the magic happens. The B2 Cockpit features state-of-the-art avionics and flight control systems. Engineers did everything in their power to make the B-2 more effective than previous bombers. She features many advanced and modern avionics systems that were integrated into her design.

The B-2 Bomber also has a Defensive Management System (DMS) that alerts the flight crew of possible threats. This onboard DMS system is capable of automatically assessing the detection capabilities of identified threats and indicated targets. This gives the B-2 a huge advantage while flying over enemy territory and is the only such system of its kind used. The flying wing design is inherently unstable in flight and almost impossible to control without flight computers.

B2 Stealth Bomber Cockpit

This is why the B-2 was fitted with a complex quadruplex computer-controlled fly-by-wire flight control system. The quadruplex computer-controlled fly-by-wire flight control system can automatically control all flight surfaces and settings without the pilot. This incredible flight control system is the reason why the B-2 can maintain aircraft stability during flight. There are other flight control systems that do remain classified to this day.

The quadruplex computer-controlled fly-by-wire flight control system receives its information from external conditions such as the aircraft’s angle of attack and current air speed via its pitot-static sensing plates. These pitot-static sensing plates are used instead of traditional pitot tubes. The use of pitot tubes would impair the B-2’s stealth capabilities and make her vulnerable to modern radar systems. These are just some of the systems that make her almost invulnerable.

B-2 Spirit Stealth Bomber in Action: B-2 Stealth Bomber Doing Carpet Bombing, B-2 Bomb Drop & More

Most of the B-2 Bomber is made out of advanced carbon-graphite composite materials that are lighter than aluminum and much stronger than steel. These exotic carbon-graphite composite materials absorb most of radar energy giving her a radar signature not much larger than a small bird. This makes her nearly invisible to all radar systems around the world and allow her to penetrate enemy airspace at will which was her main mission during the Cold War.

The B-2 Bomber boasts many innovations including an alternate high frequency material (AHFM) which is an automated material application method that was incorporated to improve the B-2’s radar-absorbent properties and reduce maintenance requirements which saves the program an extraordinary amount of money and one of the reasons why she will fly up until 2032 and beyond. Northrop Grumman began applying this newly developed AHFM to operational B-2s in early 2004.

B-2 Stealth Bomber In Action

Every B-2 in service today is kept inside a climate-controlled hangar. This is an (Extra Large Deployable Aircraft Hangar System) that is more than large enough to accommodate the B-2’s 172-foot (52 m) wingspan. The main reason why the (Extra Large Deployable Aircraft Hangar System) was built is to protect the operational integrity of the B-2’s sophisticated radar absorbent material and coatings from the elements. It also serves a dual purpose in hiding the B-2 from satellites and other surveillance techniques.

Make sure you watch the B-2 documentary above and let me know what you think. You’ll get to see the B-2 in action as she carpet bombs enemy territory and uses a multiple array of other conventional weapons. Now that you’ve learned all about the AMAZING B-2 Bomber.
