Japan to test fly F-3 stealth fighter this summer

Japan's first domestically-made stealth jet, is aiming to conduct test flights this summer.
The advanced fifth-generation fighter, originates from Japan's advanced technology demonstrator-experimental ATD-X program.
The F-3's exterior is said to contain absorbing materials that can reduce radar reflection.
The F-3 still faces many practical obstacles before it can become a reality. Researchers are still exploring engine capabilities and need to figure out problems such as compressors and burners for such a high-powered engine. The fact that engines in the older F-2, which are less powerful than those in the F-3, have malfunctioned during flights, with reports of strong vibrations during high speeds, demonstrates that Japan's engine technology is not sufficiently mature.
