The X-44 design had a reduced radar signature (due to lack of tail and vertical stabilizers) and was made more efficient by eliminating the tail and rudder surfaces, and instead using thrust vectors to provide yaw, pitch and roll control. [1] The X-44 MANTA design was based on the F-22. The engine and fuselage would be carried over to the X-44.
The resulting X-44A (although apparently unrelated to the previously developed X-44 MANTA) was built in 1999 and first flew in 2001, [1] representing an interim design between the Darkstar and P-175 Polecat. However, Lockheed Martin kept the X-44A under wraps until February 2018. [1] [2] [3] The X-44A successfully tested multiple technologies.

This list of United States Tri-Service aircraft designations includes prototype, pre-production and operational type designations under the United States Tri-Service aircraft designation system, which replaced the 1924 Air Force, 1922 Navy, and 1956 Army designation systems in 1962.
The CL-1201 design project studied a nuclear-powered aircraft of extreme size, with a wingspan of 1,120 feet (340 m). [4] Had it been built, it would have had the largest wingspan of any airplane to date, [5] and more than three times that of any aircraft of the 20th century.
The Lockheed Martin F-35 Lightning II is a family of stealth multirole fighters that first entered service with the United States in 2015. The aircraft has been ordered by program partner nations, including the United Kingdom, Italy, Norway, and Australia, and also through the Department of Defense's Foreign Military Sales program, including Japan, South Korea, and Israel.
