Lockheed Martin is actively pursuing hypersonic aircraft, estimating that it can build a fighter-sized demonstrator capable of reaching Mach 6 for less than $1 billion. The manufacturer revealed this week that it is advancing multiple platforms that would travel at or beyond hypersonic speed of Mach 5, or five times the speed of sound.
