The Shenyang J-50 is a temporary designation given by military analysts and defense media to a twin jet tailless lambda wing aircraft under development by the Shenyang Aircraft Corporation (SAC). The aircraft was observed in flight testing in Shenyang, Liaoning, China in December 2024, which was tentatively named Shenyang J-XD or Shenyang J-50 by analysts, given the limited available information.

Intended to be the leading American advanced tactical fighter in the early part of the 21st century, the Raptor is the world's most expensive fighter to date costing about $120 million per unit, or $361 million per unit when development costs are added.

The T-72, which entered production in 1971, was first seen in public in 1977. The T-72, introduced in the early 1970s, is not a further development of the T-64, but rather a parallel design chosen as a high-production tank complementing the T-64.

Early in June 1944, Army commanders expressed a need for a new breed of tank that could mount either a 90mm or 105mm main gun. This request was approved by the Army Staff soon thereafter even though trials of the new T26E1 had already begun back at Fort Knox earlier that year.
