"The technology would be a game-changer in theatre, similar to how stealth is changing the battlespace today."<br /><br />Lockheed Martin expects the SR-72 to be operational by 2030.<br />--------------------------------------------------------<br /><br />TomoNews is your daily source for top animated news.
