But it has been long that the structure and shape of navy 37millimeter gun shrapnel do n ' t vary , so the main ballistic trajectory performance is poor , such as power n shooting precision flying time . these have been not able to adapt the need of modem weapon technology development for war field weapon equipment performance 但長期以來,海37毫米艦炮制式榴彈結(jié)構(gòu)與外形等基本上沒有變化,因此,該彈的主要彈道性能,如威力、射擊精度、飛行時間等性能較差,已逐漸不能適應(yīng)現(xiàn)代兵器技術(shù)發(fā)展對戰(zhàn)場武器裝備性能的要求。
