2021 and i still love it like CRAZY !!!! Greetings from Greek Cyprus island :)

I remember the first time i was this movie in theaters. To me it had the best sound effects, it was loud and i remember the whole theater room shaking from the explosions. It was the first time i was "wowed" by sound, of course i was pretty young at the time but it was still an awesome experience!

Real explosions, not CGI, and most often shown from one angle and not super quick cutting and repeat footage of the same quick event. Yeah, the plot is dumb and the movie goes south soon after, but this opening is kickass.

This was my childhood movie 12 years ago. I absolutely loved the shit out of this. Now, I admit the movie kinda sucked and the dialogue is cringy, but it’s one of my guilty pleasures.

Too bad it's completely fake.

RIP Mr Sam Shepard, great actor

The first time i watched this film it was awesome

About the closest you're gonna get to a proper Ace Combat movie at this point.

Welp, Jamie Foxx is definitely Chopper then. lol

I came for this on 2020 2:29

The general design of a stealth aircraft is always aimed at reducing radar and thermal detection. It is the designer's top priority to satisfy the following conditions, which ultimately decide the success of the aircraft:- Reducing thermal emission from thrust Reducing radar detection by altering some general configuration (like introducing the split rudder) Reducing radar detection when the aircraft opens its weapons bay Reducing infra-red and radar detection during adverse weather conditions

I've heard that according to IMDB, this was actually meant to be a live-action Star Fox movie, but Rob Cohen, W.D. Richter, and Original Film couldn't get the license from Nintendo (who are still sore over the car crash that is the Super Mario Bros. movie). That may be apocryphal, but I really wouldn't be surprised, and I'd have liked to have seen that hypothetical movie.

The Visuals in this movie make it hard to believe it's a 2005 movies

this is great!

I love this movie! Its my favourite.👍👍👍

Perfection ; Expect the unExpected

The stealth technology aircraft were designed for photographic reconnaissance missions and for attack missions, as the first line of battle to detect and destroy enemy radars, and allow conventional attack aircraft to carry out combat operations within enemy territory.

A low-probability-of-intercept radar (LPIR) is a radar employing measures to avoid detection by passive radar detection equipment (such as a radar warning receiver (RWR), or electronic support receiver) while it is searching for a target or engaged in target tracking. This characteristic is desirable in a radar because it allows finding and tracking an opponent without alerting them to the radar's presence. This also protects the radar installation from anti-radiation missiles (ARM). LPI measures include: Power management and high duty cycle (long integration times) Wide bandwidth (or Ultra-wideband) Frequency Agility, and frequency selection Advanced/irregular scan patterns Coded pulses (coherent detection) High processing gain Low sidelobe antennas

great movie ever!!

Also, such aircraft as the F-22 Raptor and F-35 Lightning II Joint Strike Fighter can also carry additional weapons and fuel on hardpoints below their wings. When operating in this mode the planes will not be nearly as stealthy, as the hardpoints and the weapons mounted on those hardpoints will show up on radar systems. This option therefore represents a trade off between stealth or range and payload. External stores allow those aircraft to attack more targets further away, but will not allow for stealth during that mission as compared to a shorter range mission flying on just internal fuel and using only the more limited space of the internal weapon bays for armaments.

And I remember that this movie was in theaters on the day of my bday...

This was a pretty fun action movie

A stealth aircraft, also called a radar-undetectable aircraft, invisible aircraft, or stealth aircraft, is an aircraft that has been designed to absorb and deflect radiation from radar using stealth technologies. It is also common for them to be called "invisible", which is not very correct, since in part these planes are perfectly visible and "invisibility" is only before the radars, and on the other, there are other invisible planes that do seek to minimize in as much as possible its detection by visual means. The plane invisible to radar is the product of the combination of several anti-detection factors and the use of a weakness of the AA / IR missiles (Infrared Anti-Aircraft), to avoid as much as possible being detected by the radar signals, a fighter plane flying at low operating altitude, between mountains, valleys and with low flights at sea level, it can also become a plane invisible to radar, for a stealth attack against enemy positions and a ship at sea.

this movie intro scene very fantastic

That female computer voice at the start is AWESOME!!!

Ways of reducing the profile of a radar include using wider bandwidth (wideband, Ultra-wideband), frequency hopping, using FMCW, and using only the minimum power required for the task. Using pulse compression also reduces the probability of detection, since the peak transmitted power is lower while the range and resolution is the same. Constructing a radar so as to emit minimal side and back lobes may also reduce the probability of interception when it is not pointing at the radar warning receiver. However, when the radar is sweeping a large volume of space for targets, it is likely that the main lobe will repeatedly be pointing at the RWR. Modern phased-array radars not only control their side lobes, they also use very thin, fast-moving beams of energy in complicated search patterns. This technique may be enough to confuse the RWR so it does not recognize the radar as a threat, even if the signal itself is detected. In addition to stealth considerations, reducing side and back lobes is desirable as it makes the radar more difficult to characterise. This can increase the difficulty in determining which type it is (concealing information about the carrying platform) and make it much harder to jam. Systems that feature LPIR include modern active electronically scanned array (AESA) radars such as that on the F/A-18E/F Super Hornet and the passive electronically scanned array (PESA) on the S-300PMU-2 missile.

Radar systems work by sending out a signal and then listening for its echo off distant objects. Each of these paths, to and from the target, is subject to the inverse square law of propagation in both the transmitted signal and the signal reflected back. That means that a radar's received energy drops with the fourth power of the distance, which is why radar systems require high powers, often in the megawatt range, to be effective at long range. The radar signal being sent out is a simple radio signal, and can be received with a simple radio receiver. Military aircraft and ships have defensive receivers, called radar warning receivers (RWR), which detect when an enemy radar beam is on them, thus revealing the position of the enemy. Unlike the radar unit, which must send the pulse out and then receive its reflection, the target's receiver does not need the reflection and thus the signal drops off only as the square of distance. This means that the receiver is always at an advantage [neglecting disparity in antenna size] over the radar in terms of range - it will always be able to detect the signal long before the radar can see the target's echo. Since the position of the radar is extremely useful information in an attack on that platform, this means that radars generally must be turned off for lengthy periods if they are subject to attack; this is common on ships, for instance. Unlike the radar, which knows which direction it is sending its signal, the receiver simply gets a pulse of energy and has to interpret it. Since the radio spectrum is filled with noise, the receiver's signal is integrated over a short period of time, making periodic sources like a radar add up and stand out over the random background. The rough direction can be calculated using a rotating antenna, or similar passive array using phase or amplitude comparison. Typically RWRs store the detected pulses for a short period of time, and compare their broadcast frequency and pulse repetition frequency against a database of known radars. The direction to the source is normally combined with symbology indicating the likely purpose of the radar - Airborne early warning and control, surface-to-air missile, etc.

Instability of design Early stealth aircraft were designed with a focus on minimal radar cross section (RCS) rather than aerodynamic performance. Highly stealth aircraft like the F-117 Nighthawk are aerodynamically unstable in all three axes and require constant flight corrections from a fly-by-wire (FBW) flight system to maintain controlled flight.[17] As for the B-2 Spirit, which was based on the development of the flying wing aircraft[18] by Jack Northrop in 1940, this design allowed for a stable aircraft with sufficient yaw control, even without vertical surfaces such as rudders.

La aerodinámica se desarrolla a partir de las ecuaciones de Newton. Con las ecuaciones de continuidad, cantidad de movimiento y energía se pueden obtener modelos que describen el movimiento de los fluidos. Un caso particular ocurre cuando el movimiento del fluido es estacionario, es decir, las propiedades del fluido solo cambian con la posición en el campo fluido pero no con el tiempo, y cuando además se puede despreciar la viscosidad del fluido. Con estas dos características, movimiento estacionario y no viscoso, se puede obtener una función potencial que al ser derivada se obtenga la velocidad del fluido en cada punto del campo. Una vez hayamos obtenido la velocidad del fluido, podremos hallar otras magnitudes importantes. La aerodinámica clásica que explica cómo se genera la sustentación en los perfiles aerodinámicos se basa en movimientos potenciales. Este tipo de movimiento es ideal, ya que la viscosidad nula nunca se consigue.

However, modern high-sensitivity microphones, extremely sensitive audio amplifiers and high linear amplification factors, as well as band-pass audio filters (which discriminate the sonic frequency at a narrow soundtrack equivalent to airplane sound), allow the long distance detection with high accuracy. The microphones, with their parabolic reflector, are mounted in "batteries" of up to 100 groups as a kind of directional Yagi antenna. Furthermore, the sound of the plane in the air cannot be disguised and Chinese researchers have succeeded in designing and building a low-frequency radar that bounces off low-reflection surfaces at high frequencies. [

Modern stealth aircraft first became possible when Denys Overholser, a mathematician working for Lockheed Aircraft during the 1970s, adopted a mathematical model developed by Petr Ufimtsev, a Soviet scientist, to develop a computer program called Echo 1. Echo made it possible to predict the radar signature of an aircraft made with flat panels, called facets. In 1975, engineers at Lockheed Skunk Works found that an aircraft made with faceted surfaces could have a very low radar signature because the surfaces would radiate almost all of the radar energy away from the receiver. Lockheed built a model called "the Hopeless Diamond", a reference to the famous Hope Diamond and the design's predicted instability. Because advanced computers were available to control the flight of even a Hopeless Diamond, for the first time designers realized that it might be possible to make an aircraft that was virtually invisible to radar.[ Reduced radar cross section is only one of five factors the designers addressed to create a truly stealthy design such as the F-22. The F-22 has also been designed to disguise its infrared emissions to make it harder to detect by infrared homing ("heat seeking") surface-to-air or air-to-air missiles. Designers also addressed making the aircraft less visible to the naked eye, controlling radio transmissions, and noise abatement.[3] The first combat use of purpose-designed stealth aircraft was in December 1989 during Operation Just Cause in Panama. On 20 December 1989, two United States Air Force F-117s bombed a Panamanian Defense Force barracks in Rio Hato, Panama. In 1991, F-117s were tasked with attacking the most heavily fortified targets in Iraq in the opening phase of Operation Desert Storm and were the only jets allowed to operate inside Baghdad's city limits

Al igual que con otras fuerzas aerodinámicas, se utilizan coeficientes aerodinámicos que representan la efectividad de la forma de un cuerpo para el desplazamiento a través del aire. Su coeficiente asociado es conocido popularmente como coeficiente de penetración, coeficiente de resistencia o coeficiente aerodinámico, siendo esta última denominación especialmente incorrecta ya que existen varias fuerzas aerodinámicas, con sus respectivos coeficientes aerodinámicos, y cada uno de ellos tiene un significado diferente. La forma en que se estudia la resistencia aerodinámica presenta algunas particularidades según el campo de aplicación.

La primera generación de estos aviones incluye el F-117 Nighthawk y tendían a usar fuselajes con superficies angulosas para desviar las emisiones radar así como a usar materiales absorbentes de las ondas del radar (RAM). La segunda generación está representada por el B-2 Spirit. El diseño de estos aviones se ve muy beneficiado por los avances en los ordenadores capaces de modelar la respuesta de un avión a las radiaciones del radar así como mejorar la aerodinámica, siempre a costa de enormes concesiones de diseño que reducen sus prestaciones y potencialidad.

La aerodinámica es la rama de la mecánica de fluidos que estudia las acciones que aparecen sobre los cuerpos sólidos cuando existe un movimiento relativo entre estos y el fluido que los baña, siendo este último un gas y no un líquido, caso este que se estudia en hidrodinámica. Su estudio es básico para la sustentación y las superfices hipersustentadoras de las aeronaves y helicópteros.

Se denomina forma aerodinámica, o simplemente resistencia, a la fuerza que sufre un cuerpo al moverse a través del aire, y en particular a la componente de esa fuerza en la dirección de la velocidad relativa del cuerpo respecto del medio. La resistencia es siempre de sentido opuesto al de dicha velocidad, por lo que habitualmente se dice de ella que, de forma análoga a la de fricción, es la fuerza que se opone al avance de un cuerpo a través del aire. De manera más general, para un cuerpo en movimiento en el seno de un fluido cualquiera, tal componente recibe el nombre de resistencia fluidodinámica. En el caso del agua, por ejemplo, se denomina forma hidrodinámica.

Stealth aircraft are designed to avoid detection using a variety of technologies that reduce reflection/emission of radar, infrared, visible light, radio frequency (RF) spectrum, and audio, collectively known as stealth technology.[2] Well-known modern examples of stealth of U.S. aircraft include the United States' F-117 Nighthawk (1981-2008), the B-2 Spirit, the F-22 Raptor, and the F-35 Lightning II. While no aircraft is totally invisible to radar, stealth aircraft make it more difficult for conventional radar to detect or track the aircraft effectively, increasing the odds of an aircraft successfully avoiding detection by enemy radar and/or avoiding being successfully targeted by radar guided weapons. Stealth is the combination of passive low observable (LO) features and active emitters such as low-probability-of-intercept radars, radios and laser designators.

Precision

There are four forces acting on an aircraft in flight: Push, which is the force generated by the motor and its propellers, which push the air backwards, in order to create a reaction in the opposite direction. Resistance, which is the force directly opposite to the Push. Sustainability, which is the upward force that keeps the aircraft in flight. Weight, which is the force generated by Gravity, and which is opposite to the lift. When the Push and Resistance are equal and opposite, there is a balance of forces, so the aircraft will continue to move forward uniformly (same speed). As soon as the forces are unbalanced, the conditions would change, and an increase in the thrust will bring an acceleration, while an increase in the resistance will result in a deceleration. In the same way it will happen with the other two forces, an increase in lift will cause an ascent, and an increase in weight will cause the aircraft to descend. The air that flows on an aerodynamic surface (a wing), is subject to the Laws of the Movement of Isaac Newton. Air, being a gaseous fluid, possesses inertia, and according to Newton's First Law, if it is in motion, it will remain in motion. If we introduce an aerodynamic surface into this fluid, the uniform flow of air will be altered and, based on Newton's Second Law, a force will be needed to alter the uniform state of motion of that body. The wing is the force that acts on the body (the air) to produce a change in direction. The application of this force creates a reaction of equal magnitude and opposite direction (Third Law of Newton) and that is called Sustainability. As we all know, fluids offer a resistance to the advance, depending on the density of each fluid; The resistance we have when running in a pool is not the same as the one we have when running on an athletics track. Airplanes are influenced by four fundamental forces of physics and fluid dynamics, and it is the combination of these four forces, which make possible the controlled flight of an aircraft. The thrust is generated by the engines, the support is generated by the wings (whether fixed, in airplanes, or rotating, in helicopters), while the weight is generated naturally by gravity, and the resistance is generated by the fluid that surrounds the body, in this case the aircraft, and that is the air.

You mean "thrust" "drag" "lift" and "gravity".... Nice try tho.

Hay cuatro fuerzas actuando sobre una aeronave en vuelo: Empuje, que es la fuerza generada por el motor y su hélices, que empujan el aire hacia atrás, con el objeto de crear una reacción en sentido contrario. Resistencia, que es la fuerza directamente opuesta al Empuje. Sustentación, que es la fuerza ascendente que mantiene a la aeronave en vuelo. Peso, que es la fuerza generada por la Gravedad, y que es opuesta a la sustentación. Cuando el Empuje y la Resistencia son iguales y opuestas, hay un equilibrio de fuerzas, por lo que la aeronave continuará moviéndose hacia delante de forma uniforme (misma velocidad). En cuanto se desequilibren las fuerzas, las condiciones cambiarían, y un aumento del Empuje acarreará una aceleración, mientras que un aumento de la Resistencia resultará en una deceleración. De la misma forma ocurrirá con las otras dos fuerzas, un aumento de la sustentación provocará un ascenso, y un aumento del peso hará que la aeronave descienda. El aire que fluye sobre una superficie aerodinámica (un ala), está sujeto a las Leyes del Movimiento de Isaac Newton. El aire, siendo un fluido gaseoso, posee inercia, y según la Primera Ley de Newton, si está en movimiento, se mantendrá en movimiento. Si introducimos en ese fluido una superficie aerodinámica, se alterará el flujo uniforme del aire y, en base a la Segunda Ley de Newton, se necesitará una fuerza para alterar el estado uniforme de movimiento de dicho cuerpo. El ala es la fuerza que actúa en el cuerpo (el aire) para producir un cambio en la dirección. La aplicación de dicha fuerza crea una reacción de igual magnitud y de sentido opuesto (Tercera Ley de Newton) y que se llama Sustentación. Como todos sabemos, los fluidos ofrecen una resistencia al avance, dependiendo de la densidad de cada fluido; No es lo mismo la resistencia que tenemos al correr en una piscina que la que tenemos al correr en una pista de atletismo. Los aviones están influenciados por cuatro fuerzas fundamentales de la física y la dinámica de fluidos, y es la combinación de estas cuatro fuerzas, las que hacen posible el vuelo controlado de una aeronave. El Empuje lo generan los motores, la Sustentación es generada por las alas (ya sean fijas, en aviones, o rotatorias, en helicópteros), mientras que el Peso es generado de forma natural por la Gravedad, y la Resistencia es generada por el fluido que envuelve al cuerpo, en este caso a la aeronave, y que es el aire.

Vulnerable modes of flight Stealth aircraft are still vulnerable to detection during, and immediately after using their weaponry. Since stealth payload (reduced RCS bombs and cruise missiles) is not yet generally available, and ordnance mount points create a significant radar return, stealth aircraft carry all armaments internally. As soon as weapons bay doors are opened, the plane's RCS will be multiplied and even older generation radar systems will be able to locate the stealth aircraft. While the aircraft will reacquire its stealth as soon as the bay doors are closed, a fast response defensive weapons system has a short opportunity to engage the aircraft. This vulnerability is addressed by operating in a manner that reduces the risk and consequences of temporary acquisition. The B-2's operational altitude imposes a flight time for defensive weapons that makes it virtually impossible to engage the aircraft during its weapons deployment.[citation needed] New stealth aircraft designs such as the F-22 and F-35 can open their bays, release munitions and return to stealthy flight in less than a second. Some weapons require that the weapon's guidance system acquire the target while the weapon is still attached to the aircraft. This forces relatively extended operations with the bay doors open.

"Tactical music" wow....

La resistencia total de un avión en vuelo se puede descomponer en las siguientes: Resistencia parásita Se denomina así toda resistencia que no es función de la sustentación. Es la resistencia que se genera por todas las pequeñas partes no aerodinámicas de un objeto. Está compuesta por: Resistencia de perfil: La resistencia de un perfil alar se puede descomponer a su vez en otras dos: Resistencia de presión: Debida a la forma de la estela. Resistencia de fricción: Debida a la viscosidad del fluido. Resistencia adicional: Es la resistencia provocada por los componentes de un avión que no producen sustentación, por ejemplo el fuselaje o las góndolas de los motores. Resistencia de interferencia: Cada elemento exterior de un avión en vuelo posee su capa límite, pero por su proximidad éstas pueden llegar a interferir entre sí, lo que conduce a la aparición

Aerodynamic limitations Earlier stealth aircraft (such as the F-117 and B-2) lack afterburners, because the hot exhaust would increase their infrared footprint, and flying faster than the speed of sound would produce an obvious sonic boom, as well as surface heating of the aircraft skin, which also increases the infrared footprint. As a result, their performance in air combat maneuvering required in a dogfight would never match that of a dedicated fighter aircraft. This was unimportant in the case of these two aircraft since both were designed to be bombers. More recent design techniques allow for stealthy designs such as the F-22 without compromising aerodynamic performance. Newer stealth aircraft, like the F-22, F-35 and the Su-57, have performance characteristics that meet or exceed those of current front-line jet fighters due to advances in other technologies such as flight control systems, engines, airframe construction and materials

This technique is much less useful against a radar with a frequency-agile (solid state) transmitter. Agile radars like AESA (or PESA) can change its frequency with every pulse (except when using doppler filtering), and generally does so using a random sequence, integrating over time does not help pull the signal out of the background noise. Moreover, a radar may be designed to extend the duration of the pulse and lower its peak power. An AESA or modern PESA will often have the capability to alter these parameters during operation. This makes no difference to the total energy reflected by the target but makes the detection of the pulse by an RWR system less likely.

Perfume ; Perfect T tion

Electromagnetic emissions The high level of computerization and large amount of electronic equipment found inside stealth aircraft are often claimed to make them vulnerable to passive detection. This is highly unlikely and certainly systems such as Tamara and Kolchuga, which are often described as counter-stealth radars, are not designed to detect stray electromagnetic fields of this type. Such systems are designed to detect intentional, higher power emissions such as radar and communication signals. Stealth aircraft are deliberately operated to avoid or reduce such emissions. Current Radar Warning Receivers look for the regular pings of energy from mechanically swept radars while fifth generation jet fighters use Low Probability of Intercept Radars with no regular repeat pattern

The fighting is probably south Of Saudia Arabia or further into North Africa by the "Syrian=African Rift" (Great Rift Valley),en.wikipedia.org/wiki/Great_Rift_Valley since it starts in Syria and goes Lebanon into Israel and south to Africa. US Pilots would not be in the area of Lebanon or Israel so maybe Syria or Sudan etc. is the locale here.
