The H-6 Bomber in One Word: New. That is not a typo, and it is not a joke about relative ages.
The H-6 descends from the Tupolev Tu-16, which first flew in April 1952. But China stopped building H-6s in the early 1990s, when the design was plainly obsolete, and then restarted the production line around 2006. The bulk of the modern force, the K and N models that make up China’s front-line bomber strength, was built after that restart. The outline is seventy years old.
