අද මම කියන්න හදන්නෙ දැනට ලොකෙ තියන හොදම වර්ගයේ ප්රහාරක ගුවන් යානයක් ගැන.
මේකෙ නම තමයි F-22 Raptor
මෙක නිශ්පාදනය කරන්නෙ Lockheed Martin කියන සමාගමෙන්.
මෙක නිශ්පාදනය කරල තියෙන්නෙ 2005 වර්ශයේ.
මෙම යානය ප්රහරක multirole fighter යනයක් වන අතර රෙඩාර් වලට අසු නොවි ගමන් කිරීමේ හැකියාව හෙවත් stealth technology වලින් සමන්විතයි.
