补充资料:“河谷”级导弹快艇
“河谷”级(024)型小型导弹艇,从原苏联的“蚊”式改进而来,有较好的快速性与耐波力。
建造:首艇由芜湖造船厂制造,1966年4月开工,8月下水,12月服役,命名为66型小型导弹艇。因为“文革”影响,直到1975年2月才定型,由芜湖造船厂和上海求新造船厂生产。1980年至1982年,701所与海军4805厂将4枚 c-801型多用途导弹改装到一艘024艇上,攻击力大大加强。近年来,海军还在该型艇上进行c-101超音速反舰导弹的试验工作。
排水量:标准68吨,满载79吨
尺度:长27米,宽6.3米,吃水1.3米
动力:4台柴油机/4800马力
航速:37.5节
续航力:700公里
编制:17人
武备:“上游-1/2”双联装反舰导弹1座
25毫米/60双联舰炮1座
