THAAD is a crucial component of the US effort to deploy a multi-layered, integrated ballistic missile defense system. The "high altitude" in the name refers to the capability of the system to intercept incoming missiles at endo- and exo-atmospheric altitudes, with a maximum engagement altitude of around 93 miles (150km) above the surface of the earth. Nearly all sources agree that The THAAD missile system is developed to defend against hostile incoming threats like short range, medium range and intermediate-range ballistic missiles but not ICBMs. THAAD’s high-altitude intercept capability reduces the impact of enemy weapons before they hit the ground, and its non-explosive kinetic effect (hit-to-kill) minimizes the possibility of detonation. The missile can reach a peak speed of about eight times the speed of sound, placing it in the “hypersonic” category. A Patriot launcher carrying PAC-3 MSE missiles can now be integrated into a THAAD battery. On January 17 2022 it made its first successful intercept against an incoming Houthi missile over Abu Dhabi. This is the missile defence shield that scares China. And the North Koreans hate it!

Meet the Antonov An-225, the world's largest aircraft, which has only been produced once and is a first. Antonov An-225, which was developed for the first time to carry the space shuttle Buran belonging to the Soviet Union, was first completed in 1988 and started its flights. The AN-225 is referred to in Ukrainian as Mriya, which means "Dream." It serves as the inspiration for the Antonov Airlines tagline, "No other name carries greater weight," having set 242 world records to date. The "Antonov An-225 Mriya," which was split in two as a result of the bombardments carried out by Russia in the early days of the Russia-Ukraine war, lies in its hangar at the Antonov aircraft complex in the city of Gostomel, where fierce fighting continued until the last two days. In this episode of "Big Machines," we examine the characteristics of the largest freight plane in the world in light of the appearance of these photographs. What are the features and capacities of Antonov An-225, the world's largest aircraft? Details are in this video.

about the daily operations and activities of crews working aboard massive aircraft carriers.

Raytheon's RIM-7 SEASPARROW is a direct development of the AIM-7E Sparrow air-to-air missile. The SEASPARROW missile system is a highly effective surface-to-air missile that is primarily used by naval forces for defense against hostile aircraft and missiles. The missile features a cylindrical body with four mid-body wings and four tail fins, measuring 12 feet (3.7 m) in length and 8 inches (20 cm) in diameter. The missile weighs 510lb (230kg). It is powered by a Hercules MK-58 solid-propellant rocket motor that enables it to reach an impressive maximum speed of 2,645 mph (4,256 km/h). The missile is equipped with a semi-active radar homing guidance system, which allows it to track and engage targets accurately. The SEASPARROW missile has an operational range of 10 nautical miles (19 kilometers), making it an essential component of naval defense systems worldwide. These missiles will be launched from an old Soviet landbased system in Ukraine. Buk is a tracked, short-range air defense system. It employs semi-active radar technology that is now considered obsolete. In terms of homing technology, it is similar to the Sparrow. This similarity let the Ukrainian engineers to figure out how to launch SEASPARROW from Buk command centers, using the system's 9E420 radar to guide them to their targets

Sigiriya, considered the eighth wonder of the world, is located in Sri Lanka.

You get in your seat, place your carry-on in the overhead bin, and put your phone in airplane mode. You are familiar with this ritual at this point. Everybody has a different theory about why you have to do it but have you ever wondered what the exact reason is? Well, there is not a single answer to that question. The Federal Aviation Administration, or FAA for short, allows the in-flight use of electronic devices as long as the airline is okay with it. But the FCC doesn’t allow cell phone usage on planes to prevent disruption to cellular towers on the ground. Components like radio altimeters which calculate the altitude the plane is flying in are also important for a safe flight. Some devices are actually known to interfere with these systems. In 1999, a passenger using their handheld DVD player caused the plane to deviate 30 degrees. The device was turned off as soon as possible and thankfully the plane made it to its destination safely but this event shows that the caution some companies take is not just superstition. There are no recorded airplane crashes that were caused by cell phones. Still, the safety of everybody in the plane is too important for the airlines to take that risk.

Experts and officials agree that there are a lot of activity on the Ukraine’s border, as well as a lot of preparations, with Russian air forces deploying helicopter gunships and fighter jets. Also Russian cruise missiles and drones have shifted their focus to civilian targets. Ukraine received its first National Advanced Surface-to-Air Missile Systems (NASAMS) in late 022, providing the country with a long-awaited capability as Russian missiles and Iranian-made drones attack its infrastructure. To combat Russian aircraft and drones, in November 2022, the U.S. announced the shipment of four AN/TWQ-1 Avenger air defense systems. On January 20, 2023, eight additional systems were included in the military aid package. It is a surface-to-air missile fire unit that is lightweight, highly mobile, and easily transportable, with two missile pods each containing eight Stinger missiles. Raytheon's RIM-7 SEASPARROW is a direct development of the AIM-7E Sparrow air-to-air missile which was developed in the early 1950s as a semi-active radar-homing missile system. These missiles are planned to be launched from Soviet era 9K37 BUK (NATO designation SA-11) systems. The Pentagon recently announced that it would expedite the delivery of Patriot missiles to Ukraine. The PATRIOT employs advanced interceptor missiles and highly effective radar systems. Its average effective range is 93 miles (150 km). Please don't forget to watch our video on the operations of AN/TWQ-1 Avenger Missile System in Ukraine.

The RS-28 Sarmat known as "Satan II", is a Russian liquid-fueled, MIRV equipped super-heavy intercontinental ballistic missile (ICBM) produced by the Makeyev Rocket Design Bureau since 2009. It is intended to replace the R-36M ICBM (SS-18 'Satan') in Russia's arsenal. 🛎 Don't forget to LIKE, SUBSCRIBE, and COMMENT Below for Future Videos.
