Anti-tank guided missiles were designed to destroy tank. Many of you may wonder which is the deadliest anti-tank missile. Here is the list of some of the best man-portable anti-tank guided missiles that are currently available. This list does not include vehicle-mounted and helicopter-launched missiles.

The key factors for this Top 10 list are range and penetration of the missile. Guidance method is also considered. Priority is given to advanced fire-and-forget and top-attack type missiles. This analysis is based on specifications and available data. This list does not include missiles that are still being developed.

So which is the best anti-tank guided missile in the world? Which are the deadliest missiles of this type and why?

Last month, the National Nuclear Security Administration (formerly the Atomic Energy Commission) announced that the first of a new generation of strategic nuclear weapons had rolled off the assembly line at its Pantex nuclear-weapons plant in the panhandle of Texas. That warhead, the W76-2, is designed to be fitted to a submarine-launched Trident missile, a weapon with a range of more than 7,500 miles. By September, an undisclosed number of warheads will be delivered to the Navy for deployment.

So many discussions of ships in science fiction fall into the same tired debates. Who goes faster, the Millennium Falcon or the USS Enterprise? How big of a planet would the Death Star blow up — and how much would that ship cost, anyway? This slideshow takes things a step further. We talk about the most creative ships of science fiction. Yes, you'll see some familiar names on here, but we hope there will be at least a couple of surprises.

Does the Pentagon have the right weapons to fight off an alien invasion?

As summer blockbuster season kicks into high gear, big-budget action movies like The Avengers, Battleship, and Prometheus remind us that there’s one thing that unites Americans: Our shared fear of an alien attack. They also remind us that when the invading space fleet arrives, humanity is not going to surrender without a fight to our intergalactic invaders. Instead, we will band together to fight off their incredibly advanced weaponry with our … well, with what, exactly? Are we really ready to battle our would-be alien overlords?

Over the course of six years, from 1 September 1939 to 2 September 1945, upwards of 80 million men and women were killed as total war erupted between the Axis and Allied Powers, obliterating much of Europe, Asia and the Pacific, and bankrupting many of the most powerful regimes on Earth.

Characterised by countless massacres, the Holocaust, civilian bombing, famine and nuclear weapons, the war helped shape international legislation that would dictate the future of global politics. It led to the formation of the United Nations but also plunged the US and USSR into a decades-long Cold War.

In light of increasing tensions in global hot spots, U.S. military R&D is gaining more urgency. The U.S. will spend nearly $80 billion this year to create new weapons, armor and related gear, up 5% from last year. Even higher spending is planned for 2017.The next array of weapons to outgun the old and explore new discoveries in science and security are coming from defense contractors, university labs and small tech start-ups with big aims. They serve not so much to amaze war tech geeks but to protect and defend...and win.

Are we alone in the universe? Do alien life forms exist and are UFOs (Unidentified Flying Objects) real? These questions, often a theme in Hollywood films and for science fiction writers, may not seem as implausible now as they used to. 

“I’m not saying that it’s aliens. But it’s aliens.”

That’s the tagline of a famous internet meme based on Giorgio Tsoukalos’ History channel show, “Ancient Aliens.” But now it seems to be the official United States government line, too.

Americans have fought in many wars, within their own country as well as abroad. These wars were fought for a variety reasons, ranging from the need to be independent from colonists to the expansion of national boundaries.

Here’s a list of American wars that took place since the United States became an independent nation.

from the enormous Tsar Bomba, detonated with the force of 3,800 Hiroshima explosions, to the Mk-41, the biggest thermonuclear device ever built by the US, here’s a list ranking 10 of the world’s most powerful nuclear weapons based on explosive power (or yield).
