Top 5 most populous megacities worldwide
The United Nations has released fresh data on the most populous cities in the world. Let's take a look at the top megacities by population.
A Lockheed Martin F-35A Lightning II – The F35 Joint Strike Fighter program is the most expensive military weapons system in history. It is multipurpose fighter of the fifth generation, created by Lockheed Martin in three versions. The price is $ 1.5 billion.
Donald Trump has again criticised the cost of Lockheed Martin's F-35 fighter jet and tweeted that he has asked Boeing to offer a price for an older aircraft that lacks the same stealth capabilities. At the moment, the purchases of a combat vehicle are carried out for $ 94.6 million, and in 2019 it is planned to reduce the cost to to $ 80-85 million.
A single Arleigh Burke costs $1.843 billion, while all of the Arleigh Burkes in existence have cost about $101.8 billion. Like other destroyers, it is a small but fast and maneuverable warship intended to protect bigger ships from short-ranged attackers, but it is interesting in that it makes extensive use of guided missiles. Said weapons range from anti-aircraft missiles and anti-surface missiles to Tomahawk missiles that can be used for strategic purposes. Of course, the Arleigh Burke is also armed with other equipment such as torpedoes, 5-inch guns, and mine detectors, thus enabling it to serve in an even wider range of roles.
Despite being a less expensive counterpart to the Seawolf-class submarine, the Virginia-class submarine cost $83.7 billion. In brief, it is a nuclear-powered attack submarine meant to serve in littoral waters as well as the open ocean. As a result, it comes with a wide range of weapons, which include but are not limited to mines, torpedoes, and even Tomahawk missiles.
The fourth line in this ranking is occupied by F-22 Raptor. It is a multipurpose fighter of the fifth generation, created by Lockheed Martin, Boeing and General Dynamics. In total, the F-22 Raptor cost $79.2 billion, which is appropriate considering that it is a state-of-the-air stealth fighter. As a result, it should come as no surprise to learn that it has two short-range air-to-air missiles and six medium-range air-to-air missiles, which are supposed to enable it to blast its opponents out of the air before they can even notice its presence.
The fifth place among the most expensive weapons is given to the F / A-18E / F Super Hornet. The F / A-18E / F Super Hornet strike fighter is an upgrade of the combat-proven night strike F/A-18C/D. The Super Hornet will provide the battle group commander with a platform that has range, endurance, and ordnance carriage capabilities comparable to the A-6 which have been retired. The cost of a combat vehicle is just over $ 57 million.
The sixth place goes to the V-22 Osprey – an American convertor, which has a number of advantages of an airplane and a helicopter. With the ability to convert into a rotary wing helicopter for takeoff and landing and the ability to turn into a fixed wing aircraft for sustained flight, the V-22 Osprey is definitely the most unique aircraft in service. The aircraft has two engines Rolls-Royce T406, located at the ends of the wing in the gondola, which are able to rotate almost 98 degrees. The cost of the aircraft is $ 57.8 billion.
The Trident-2 missile closes the list of the most expensive military weapons. The Trident II missile sees use in both the U.S. Navy and the British Navy. In brief, it is classified as a SLBM, meaning that it is a ballistic missile that is launched at its intended target from a submarine, with the result that it can move up to 13,000 miles per hour. It has never been used, and assuming that things go well, it will never be used because it is armed with nuclear warheads. The Trident-2 missile is estimated at $ 53.2 billion.

Deepfake is a technology based on artificial intelligence to create ultra-realistic fake videos, audio, and images featuring real people. In recent years, it has gained incredible popularity, evoking both admiration and concern. Celebrities, whose faces are often used for such purposes, have felt its impact most acutely. In this article, we will discuss five of the most "deepfaked" individuals who have become the main victims of this emerging technology.
The biggest news of recent days has been Donald Trump's victory in the US presidential election. This event has caused a stir around the world, reminding us of the significant role a US president plays in both national development and international affairs. Throughout US history, several presidents have dramatically reshaped the country's domestic landscape and strengthened its influence abroad. Let's take a look at some of the most influential
