NASA's experimental supersonic X-plane, that it hopes will help them commercialize supersonic travel, will officially be known as the X-59 QueSST moving forward, according to an Mlive report.

The US space agency has said that if it can "lower sonic booms to a low rumble" then commercial jets could be able to make the cross-country trip from New York to Los Angeles in two hours in the future.

Back in May, NASA awarded Lockheed Martin a $247.5 million contract to build the experimental X-Plane. 

NASA says that the US Air Force informed them of the decision to designate the experimental supersonic plane with an X-number name earlier this week on June 26. The X-plane designation "continues a tradition of naming important experimental aircraft and rockets that dates back to 1947 and the X-1." 

"For everyone working on this important project, this is great news and we're thrilled with the designation," Jaiwon Shin, NASA's associate administrator, said in a news release. 

"I'm confident that the contributions the X-59 QueSST will make to our nation and the world will ensure its place among the greatest NASA X-planes ever flown."

The space agency says that the plane is currently under construction with Lockheed Martin in California.

Once the X-59 QueSST is fully tested and deemed safe to fly in the National Airspace, NASA says it will begin making "supersonic flights over select communities to measure residents' reactions" in 2022. 

NASA says the X-plane's design is based on a Lockheed Martin preliminary design, which will make an aircraft 94 feet long with a wingspan of 29.5 feet and weigh in at 32,300 pounds with a full tank of fuel.

Once complete and ready for flight, the space agency says the plane will cruise at an altitude of 55,000 feet at 940 mph, and that its top speed will be a projected 990 mph with one pilot in the cockpit.
