Fighter jets are aircraft designed for combat and tactical missions. They are known for their speed, agility, and ability to engage in high-speed aerial maneuvers. The development of fighter jets has progressed over time, with modern jets capable of flying at speeds exceeding 1,000 miles per hour. The speed of fighter jets is typically measured using Mach numbers, which represent the ratio of the plane's speed to the speed of sound. Mach 1 is the speed of sound, and fighter jets that surpass this speed are classified as supersonic aircraft. These supersonic jets can intercept other aircraft, break the sound barrier, and create sonic booms. The performance of fighter jets has continued to advance, with some jets achieving speeds of Mach 2 and even higher, showcasing the remarkable engineering and design that enable them to excel in the skies.

What You'll Learn
Fighter jets are a type of supersonic aircraft
The speed of sound is referred to as Mach 1, and it is measured as a ratio of the speed of an aircraft to the speed of sound. As aircraft approach and exceed Mach 1, they create a sonic boom, an impulsive noise similar to thunder caused by the compression associated with the shock waves generated by the aircraft moving faster than sound. Fighter jets are designed to withstand the extreme forces and stresses exerted on their structures when flying at supersonic speeds, utilizing strong materials such as titanium and stainless steel.
Over the years, fighter jet speeds have continued to increase, with modern jets capable of flying over 1,000 miles per hour. The MiG-25 Foxbat, for example, has a top speed of Mach 3.2 or 2,190 miles per hour. The NASA/USAF X-15 is even faster, reaching Mach 6.72 or 4,520 miles per hour. Many fighter jets can exceed Mach 2, with some going beyond Mach 2.5. The F-22 Raptor, a 5th-generation fighter jet, can fly faster than Mach 1.2 at sea level and can supercruise at speeds above Mach 1.8 without using afterburners, resulting in greater fuel efficiency.
The development of supersonic aircraft, including fighter jets, occurred during the second half of the twentieth century. While most supersonic aircraft have been used for research and military purposes, a few, such as the Tupolev Tu-144 and the Concorde, have been utilized for civil air travel. The design of fighter jets emphasizes speed as a critical factor, and their ability to fly faster than sound gives them a distinct advantage in aerial combat and tactical missions.

Mach numbers are used to measure speed
Fighter jets are aircraft capable of supersonic flight, meaning they can fly faster than the speed of sound. Supersonic aircraft were developed in the second half of the twentieth century and are used for research and military purposes.
The Mach number is defined as the ratio of two speeds and is a dimensionless quantity. It is named after the physicist and philosopher Ernst Mach. The word "Mach" is always capitalized since it derives from a proper name. As the Mach number increases, so does the strength of the shock wave, and the Mach cone becomes narrower.
Supersonic aircraft, such as fighter jets, create a shock wave or "sonic boom" when flying faster than the speed of sound. The aerodynamics of supersonic flight is called compressible flow due to the compression associated with the shock wave. Supersonic aircraft usually use low-bypass turbofans, which have acceptable efficiency below and above the speed of sound.

Quick acceleration and sharp turns are key in combat
Fighter jets are the most common example of supersonic aircraft, capable of flying faster than the speed of sound (Mach 1). Quick acceleration and sharp turns are key in combat, and fighter jets are designed to excel in these areas.
The thrust-to-weight ratio is critical to a fighter jet's speed and acceleration. A balance of lightweight design and powerful engines leads to superior performance. Over time, fighter jet technology has evolved, and modern jets like the F-22 and F-35 have more powerful engines that can push speed limits even further.
Altitude also plays a significant role in fighter jet speed. At higher altitudes, the thinner air results in less drag on the plane, enabling fighter jets to achieve faster speeds. Additionally, the design of variable-sweep wings on fighter jets changes with different air conditions, affecting lift and maneuverability. Highly swept wings are generally more stable and less susceptible to sudden lift drops compared to moderately swept wings.
The development of the afterburner, which burns extra fuel in the jet exhaust, contributed to the advancement of supersonic flight. Today, supersonic aircraft are often powered by turbofans fitted with afterburners, allowing for efficient flight both below and above the speed of sound. The future of fighter jet speed lies in hypersonic flight, with countries working on developing hypersonic fighter jets that can achieve speeds over Mach 5.
The speed of fighter jets is crucial in modern air combat. It enables them to quickly intercept threats, evade enemy fire, and gain tactical advantages. High speeds allow fighter jets to rapidly close in on targets and maneuver defensively. While speed is essential, it also comes with challenges, such as increased stress on the aircraft and higher fuel consumption.

Sonic booms are created when breaking the sound barrier
Fighter jets are aircraft that can travel faster than the speed of sound, which is about 750 to 761 miles per hour at sea level. When an aircraft travels faster than the speed of sound, it breaks the sound barrier, creating a sonic boom.
Sonic booms are extremely loud, thunderous sounds that can be heard when an object surpasses the speed of sound. They are created by the pressure of air molecules being disturbed by the aircraft's speed. As the aircraft accelerates, it creates ripples of air molecules and sound that radiate outwards in every direction. However, as the aircraft continues to speed up, the waves at the front of the aircraft start to compress and pile up instead of rippling outwards. This creates so much pressure that it releases a large sound wave, known as a shock wave, which manifests as a loud, booming noise.
The first aircraft to break the sound barrier was the Bell X-1 rocket plane in 1947, piloted by Charles "Chuck" Yeager. Breaking the sound barrier allows fighter jets to become incredible fighting machines, capable of intercepting other aircraft and targets over vast distances at great speed. However, the sonic booms that accompany supersonic flights have proven unpopular with people on the ground. As a result, the Federal Aviation Administration (FAA) has prohibited sonic booms over densely populated areas since 1973 to prevent potential damage and disturbance.
The characteristics of a sonic boom can vary depending on factors such as the aircraft's length, speed, flight track, altitude, and sea level. Most fighter jets produce a double boom, while larger aircraft might generate more complex boom patterns. The size of the sonic boom carpet, or the area of impact, increases with the height of the aircraft, with NASA calculating that a plane traveling at 50,000 feet will create a sonic boom carpet that is 50 miles wide.
