Russia vs. China vs. America: The Hypersonic Weapons Arms Race Is Here

Scientists with the Air Force Research Laboratory and the Pentagon's research arm are working to build a new hypersonic air vehicle that can travel at speeds up to Mach 5 while carrying guidance systems and other materials.

Air Force senior officials have said the service wants to build upon the successful hypersonic flight test of the X-51 Waverider 60,000 feet above the Pacific Ocean in May of 2013.

The Air Force and DARPA, the Pentagon's research entity, plan to have a new and improved hypersonic air vehicle by 2023.

5 Naval Battles That Changed History Forever

Needless to say, drawing up a list like this one is tough. Many worthy candidates ended up on the cutting-room floor. China's Ming Dynasty was born through inland naval warfare, at the Battle of Lake Poyang (1363). The Battle of the Virginia Capes (1781) doomed Lord Cornwallis' army at Yorktown and assured American independence. The naval battles at Guadalcanal (1942-1943) reversed the tide of war in the Pacific, while the Battle of the Philippine Sea (1944) doomed Japanese naval aviation—paving the way for history's last major fleet engagement, at Leyte Gulf later that year.

Water War: Russia's Battlecruiser Kirov vs. America's Stealthy Zumwalt (Who Wins?)

In a battle between the two ships, which would prevail? Let’s assume place the two ships on the high seas at the maximum range of either side’s antiship weapons: 300 miles, the range of Kirov’s Granit missiles. Unlike previous scenarios, we’ll not assume that each ship knows where the other is, but that eventually, one will find the other. Kirov has the Legenda satellite system working for it, but Legenda is a radar satellite, and Zumwalt is a stealthy destroyer with the radar signature of a small fishing boat.

Trump's Riyadh Speech: Bowing to the Saudi Regime

The bar for Donald Trump’s speech in Riyadh had been set so low that it was scraping the sand.  How much could be expected from a notorious exploiter of Islamophobia speaking to a gathering of leaders of majority Muslim countries?  Getting through the experience without causing major new damage should perhaps be considered a success.  Perhaps Trump and his speechwrite

How the U.S. Army Is Using Old Artillery to Fire Hypervelocity 'Bullets'

Due to its ability to reach speeds of up to 5,600 miles per hour, the hypervelocity projectile is engineered as a kinetic energy warhead, meaning no explosives are necessary. The hyper velocity projectile can travel at speeds up to 2,000 meters per second, a speed which is about three times that of most existing weapons. The rate of fire is 10-rounds per minute, developers explained at last years' briefing.
