【民船设计】--- 北极号电子科考船
1929年，在得到法国的大力帮助下，基于国民经济的发展，民用船只开始有了起色。民间团体要求国家发展民用科考船只， 北极号在这样的大背景下完工。上面装有法国和美国的最新式的科考电子设备。

舷窗离水线太近，极为危险，白白安装装甲。 巴掌 发表于 2011-7-1 10:54 static/image/common/back.gif

我的意思是，北极科考船的水线附近设置舷窗，有被浮冰撞碎的危险。 巴掌 发表于 2011-7-1 11:03 static/image/common/back.gif

这个，老X啊，你不是用的智利么……怎么又来了个CHINA，还北极……科考“穹面钢甲快船”？ 无用的大白象吧？你要这玩意儿何用？而且智利的电子水平当时提不上趟吧？ 小胡子 发表于 2011-7-1 19:06 static/image/common/back.gif

有些桌面下的交易你不知道
北极科考？看来是想阴我了。
和平时期你怎么靠不管，战争时期我是要划出战区的，未经允许的船进入就等着发生海难吧。 回复 巴掌 的帖子
巴掌淡定，这是我援助了智利一所大学以及若干科研机构后的产物之一，目的在于扶植智利发展科技。 智利放着好端端的南极不去，偏来北极，动机很让人怀疑啊。
