While there are no existing prototypes of the aircraft, the artist rendering is based on the initial design concept. The designation B-21 recognizes the LRS-B as the first bomber of the 21st century.
James also explained why the B-21 shares some resemblance to the B-2.
“The B-21 has been designed from the beginning based on a set of requirements that allows the use of existing and mature technology,” James said.
