Lockheed Martin continues to invest in propulsion technologies and advanced materials needed for hypersonic speeds.

For comparison purposes, we will pit a hypersonic get against a 747 airliner.

The latter travels at about 550 mph (885 km/h).

Hypersonic jets could become a reality by the year 2023

At such hypersonic speeds, an aircraft could fly across the Pacific Ocean in between 1 to 2 hours.

Now, Lockheed suggests they are closer to building a hypersonic craft at an affordable price.
