Germany and the United States have sent tons of of Stinger missiles (like this one being fired during a Marine Corp training mission) to assist Ukraine combat the invasion from Russia. U.S. Navy picture by Mass Communication Specialist 2nd Class Chandler Harrell
When Russia invaded Ukraine in late February 2022, outnumbered Ukrainian defenders on the ground had been susceptible to attack from Russian helicopters, which also had the ability to transport Russian troops rapidly around the beleaguered smaller nation. That’s why the U.S. and its NATO ally Germany decided to provide the Ukrainians a potent weapon that may assist even the percentages – the Stinger antiaircraft missile [sources: Rfel.org, Gould and Altman].
As retired Army Lt. Gen. Jim Dubik told the publication Army Times, the Stinger is a weapon with the potential to be “a game changer,” giving soldiers on the ground the power to contest the airspace, and hinder the enemy’s skill to conduct operations [source: Gould and Altman]. The weapon’s effectiveness was demonstrated back within the mid-1980s, when Afghan resistance forces used Stinger missiles given to them by the CIA to shoot down Soviet helicopters. Some specialists credit Stingers with having altered the course of that conflict, and being a significant issue within the Soviets’ eventual defeat [supply: Woody]. Stingers additionally are used on the U.S. Army’s AH-sixty four Apache combat helicopter as an air-to-air weapon [source: Raytheon Missiles & Defense]. And they can be mounted on ground vehicles as well [source: Judson].
Along with being versatile, the Stinger missile can also be highly correct, as a result of it makes use of an infrared seeker to lock on to the heat in the engine’s exhaust, and can hit nearly something flying beneath 11,000 feet (3,352 meters).
The Stinger was developed in the early 1970s [supply: Trimble]. But it’s nonetheless fearsome. Through the years, Stingers have been battle-examined in several conflicts, and today they’re in the arsenals of 19 nations, and are used by four U.S. military branches [source: Raytheon Missiles & Defense].
In this text, you’ll have an opportunity to learn concerning the Stinger missile, and the way it’s utilized on the battlefield. Federation of American Scientists
The Stinger missile, formally known as the FIM-92A, is designed to present ground troops a option to deal with low-flying airplanes and titanium forging helicopters. From the attitude of troopers on the ground, low-flying enemy aircraft are normally a problem as a result of they’re either bombing or strafing (attacking repeatedly with bombs or machine-gun fire), doing surveillance work, or inserting, extracting and resupplying enemy troops. Shooting down these aircraft is the easiest strategy to get rid of these threats. The missile and its launcher weigh about 35 pounds (15 kilograms). The launcher is reusable. Each missile is a sealed unit that weighs only 22 pounds (10 kilograms).
It is a shoulder-launched weapon, and one particular person can launch a Stinger missile (though you usually see a two-man staff operating the missile).
It makes use of a passive infrared seeker. The infrared seeker can lock on to the heat the goal is producing. It is called a “passive” seeker because, unlike a radar-guided missile, titanium wire it doesn’t emit radio waves in an effort to “see” its goal.
It’s a “fire-and-neglect” weapon, meaning it requires no enter from the gunner as soon as it’s fired. This allows them to take cowl, move to a different place or engage a brand new target.
Launching the Missile
To launch a Stinger missile, a soldier principally just points it on the target, and when the seeker locks on, they pull the trigger. U.S. Army
The Stinger missile consists of the guidance, tail, propulsion and warhead techniques. The tail has four folding fins that ship roll. Stability while the missile is in flight. The steering part includes the seeker assembly, a guidance meeting, a control assembly, a missile battery and four wings that present in-flight maneuverability. The warhead is equivalent to 1 pound (0.45 kilograms) of explosives encased in pyrophoric titanium. The propulsion section features a launch motor. A twin-thrust flight motor.
To hearth the weapon, the soldier goals the missile on the goal. When the seeker locks on, it makes a distinctive noise. The launch engine falls away. The principle stable rocket engine lights. This rocket propels the Stinger to approximately 1,500 miles per hour (2,four hundred kilometers per hour, Mach 2).
The missile then flies to the goal routinely and explodes.
The Stinger missile can hit targets flying as high as 11,500 toes (3,500 meters), and has a variety of about 5 miles (eight kilometers). Because of this the goal is an airplane less than 2 miles (3.21 kilometers) high and it’s visible as a form (quite than a dot), then most certainly the Stinger missile can hit it. They are extremely correct.
Stinger missiles use passive IR/UV sensors to track targets. The missiles search for the infrared gentle (heat) produced by the goal airplane’s engines and track the airplane by following that mild. The missiles additionally determine the UV “shadow” of the target. Use that identification to distinguish the target from different heat-producing objects.
Motion-sensing lights use passive infrared sensors. The sensors in a motion-sensing mild are tuned to the temperature of a human being. When the sensors see a sudden change in the amount of infrared light, they activate the light.
A motion-sensing light wants just one sensor. But a Stinger missile needs a complete array of them, because its job is to trace the target while it is flying. The nose of a Stinger missile has, essentially, an infrared digital digicam in it. This digicam might have an array of anything from 2×2 (in older designs) to 128×128 (in the Sidewinder design) infrared sensors that obtain an infrared image of the scene. When the soldier will get able to launch the missile, the missile should have the target visible in roughly the middle of this sensor.
While the missile is flying, the image of the airplane that it’s making an attempt to hit might turn into off-heart on the image sensor. When it does, that tells the missile that it is off-course, and the guidance system in the missile should decide the right way to get back on target. This is the place proportional navigation comes in. The missile looks at the angle of off-centeredness. Changes its angle of flight proportionally. In different words, it makes use of a multiplier. If the multiplier is 2, then if the steerage system thinks it is 10 degrees off course, it is going to change its flight path by 20 degrees. Then, a tenth of a second later it would look at the angle again, and alter once more. By over-correcting this way, it lets the missile anticipate the path of the moving aircraft in the same approach that you just anticipate the path of a transferring object.
If you’re a quarterback making an attempt to throw a ball to a receiver running throughout the sector, titanium alloy you would not throw the ball towards where the receiver is – you’d throw it towards where he will be when the ball arrives.
While the Stinger has confirmed effective over the many years, the U.S. Army already is looking for a next-technology weapon to change it.
Improving the StingerIn 2019, the U.S. Army began retrofitting its Stinger missiles with proximity fuzes. The expertise allows the missiles to destroy drone aircraft either with direct hits or by detonating near them, a capability that was demonstrated in Army testing in 2017. The modified missile provides floor troops higher protection against small, agile threats [source: Osborn, Raytheon Missiles & Defense]. U.S. Army photograph by Capt. Rachael Jeffcoat
