Chinese stealth fighter J-20 made successful maiden flight
据成都网友目击,中国歼20隐形战斗机已于2011年1月11日中午12时50分左右进行首次升空飞行测试,13时11分成功着地。整个首飞过程是在歼10S战斗教练机陪伴下完成的,历时大约18分钟,取得成功。
According to sources in Chengdu, Chinese stealth fighter J-20 succeeded in making its maiden flight at 12:50 p.m. on January 11, 2011, and landed at 1:11 p.m. The whole process was escorted by J-10S trainer aircraft. The 18-minute flight witnessed the success.

在歼-20成功完成首飞落地后,试飞现场内外欢呼声一片,机场外的围观群众也接连放起鞭炮。
After the stealth fighter landed, people at the site jumped with joys, and the masses outside the airport set off firecrackers for celebration.
专家称歼20具备跨过第二岛链攻击美军基地能力
中国引入强大的隐形能力后,美国及其西太平洋盟国的综合防空系统的覆盖范围将会大幅度削减,与1985年F-117A“夜鹰”战机出现时华沙条约综合防空系统的遭遇一般无二。
航空专家表示,该战斗机与同类美国或俄罗斯战机相比,体积较大,设计为远程战斗机。这一情况使得与中国相邻的14个国家感到不安,因为他们根本不具备生产隐形战机的技术,甚至无法监测到中国的隐形战机。
背景知识 Background information:
第四代战斗机的性能特点可以用4S来概括,即:“隐身、超音速巡航、超机动和短距起降”,其中具备革命性的就是隐身性能。隐身性能依赖于外形、材料和内部武器舱,即使是装备完全的作战配置,战斗机依然只有非常低的雷达反射截面积。
5代机4S全称为:Super Maneuverability, Super Sonic Cruise, Stealth, Superior Avionics for Battle Awareness and Effectiveness
