There's a new Sherriff in town...! Test Flights are now taking place for a new combat helicopter called the DEFIANT X from the Lockheed Martin Sikorsky-Boeing team. A newly developed helicopter that can actually reach speeds of over 400 miles an hour. This model is being proposed as the follow on to the Army's venerable Blackhawk helicopter. The DEFIANT is faster, more agile, and has more lift capability than the Blackhawk. A pretty cool video put out by the DEFIANT development team. Enjoy!
