Russia tests stealth jet designed to be invisible to radar

**A new stealth fighter has made its maiden flight in Russia’s far east.**The Sukhoi T-50 jet spent 47 minutes in the air over Komsomolsk-on-Amur and test pilot Sergei Bogdan said “it is easy and comfortable to pilot”.

The jet - also known by the Russian designation PAK FA - is seen as a potential rival to the US F-22 Raptor, which first flew in 1997.

The “fifth generation” jet is designed to be invisible to radar. Russia’s air force hopes to acquire it in 2015.
