Currently the only nations able to produce such technologies are the United States, Japan (Invisible Clothing), Israel, and the United Kingdom (Joint Project with Israel and the USA). Possible countries with such technology include Germany, France, and Italy (Which are included in many joint US Military Projects - I.E. The Joint Strike Fighter). Nations which claim such technologies are China, Russia, and Iran. Out of the 3 Russia may be the only one that could possibly attain or produce such technology. Chinese produced military aircraft are usually upgraded Russian technology as well as stolen US technology. Iran has failed to provide any evidence they can replicate any thing close to invincibility technology, this claim should be taken with a grain of salt considering Iran still possesses 30yr old F-15s that they can not replicate the part for military use.
