Stealth and Speed: America's SR-71 Blackbird Might Be Old (But Still the World's Fastest Plane)

The Blackbird’s design reflected the fact that it was pushing the limits. The crew wore pressure suits like those used on space missions to withstand the high altitudes they were flying at, and were treated to a medical exam and a high-protein steak and egg meals before each mission. The SR-71’s J58 engines could only start through use of two vehicle-mounted V8 starter engines, and the triethylborane used in the fuel would belch green flames during ignition.

Here's Who Would Win Between Nazi Germany's Bismarck and the Navy's Last Battleship

The larger context of the battle—the U.S. Navy being forced to take on the German Navy—would have had serious repercussions for the Pacific theater. Germany was, after all, considered the primary threat, with Japan second and Italy third. A more powerful German Navy (or weaker Royal Navy) would have had second order consequences for the Pacific, delaying the Solomons campaign, including the invasion of Guadalcanal, the Battle of the Coral Sea, and even the Battle of Midway.

The aircraft only exists in the context of a video game called “Call of Duty: Advanced Warfare”—however, there was once a real world concept that looks similar to the fiction jet.

B-2 Bombers in Guam Send a Message to North Korea (and Russia and China)

The United States Air Force has moved three of its stealthy Northrop Grumman B-2 Spirit strategic bombers to Guam as tensions continue with North Korea. But while the Pentagon does not deny that the arrival of the stealth bombers on Guam is designed to send a signal to Pyongyang, the message is not aimed solely at North Korea. It is a message aimed at Russia and China, who are also in the region.

These 5 Sniper Rifles Can Turn a Solider into a Super Killer

The sniper, a soldier trained in precision, long-range fire, is one of the most feared opponents on the battlefield. Snipers can make their presence felt far beyond a typical soldier’s assault rifle, cutting down enemy leaders, radio and heavy weapons operators, and damaging enemy equipment at considerable distances. This requires a weapon and optic capable of extreme accuracy, typically no more than half-an-inch of deviation per 100 yards. Here are five of the most common—and effective—sniper rifles.
