The combined DARPA and U.S. Air Force Hypersonic Airbreathing Weapon Concept (HAWC) flight test was once again successful.
With its Aerojet Rocketdyne scramjet, the Lockheed Martin version of the missile capped a program that accomplished all of its initial objectives.
It was the last flight test for HAWC, which gave the Air Force Research Laboratory (AFRL) important information to help it improve hypersonic technology.
The Lockheed Martin missile flew again faster than Mach 5, higher than 60,000 feet, and farther than 300 nautical miles.

Today, however, the tactical risks of modern special operations missions to rescue American citizens or capture terrorists pale in […]

The Heckler & Koch P7, which used to be called the PSP for “Polizei Selbstlader Pistole,” has a powerful round but is small enough to fit in a pocket or holster.
