我还把自由轮的货舱平面图和甲板平面图翻译过来了，各位争论自由轮如何装载货物的仁兄大可参考.附带还找了些模型图片，可以非常清楚地了解自由轮的总体布置。
Liberty Ships built by the United States Maritime Commission in World War II

The first of the 2,751 Liberty ships was the SS Patrick Henry, launched on Sept. 27, 1941, and built to a standardized, mass produced design. The 250,000 parts were pre-fabricated throughout the country in 2,500ton ctions and welded together in about 70 days. One Liberty ship, the SS Robert E. Peary was built in four and a half days. A Liberty cost under $2,000,000.
组装自由轮的预制构件
2751艘自由轮的首船SS Patrick Henry“帕特里克·亨利号” 于bountiful1941年9月27日开始按照大规模生产的标准规格建造。总重超过2500吨的美容美容培训250，000个预制构件在大约70天内从遍布全国的各个生产厂被运送到船厂中焊接起来。“罗伯特·皮尔里”号自由轮甚至在4做一个快乐的人small天半内建造完成。1艘自由轮的造价在200万美圆以下。（此处的2751艘和该文后面给出的数据：开工2711艘，完成2710艘不符，原因不明；每艘自由轮的平均造价是180万美圆，后文有提及）
Liberty ships were named after prominent (decead) Americans, starting with Patrick Henry and the signers of the Declaration of Independence. 18 that were named for outstanding African-Americans. Any group which raid $2 million dollars in War Bonds could suggest a name for a Liberty ship.
自由轮一般是用以故的美国名人名字命名，由帕特里克·亨利这个美国独立宣言署名人作为首舰命名。其中18艘自由轮是以著名的非洲裔美国人的名字命名的。而任何团体只要认购200万美圆的战争债券就可以为1艘自由轮提名。
Fully asmbled, the engine weighs 270,000 pounds. It stands 19 feet tall and is 21 feet long. The ship's four-bladed propeller, 18 feet in diameter, is directly coupled to the engine, which is designed to turn at a maximum of 76 rpm. This gave Liberty ships a top speed of about 11 knots. Aboard the BROWN the engine is normally run at 65 rpm, which saves fuel and is easier on the engine. This gives an average speed of around 10 knots. Power output from the engine is 2,500 horpower. Fuel consumption is about 170 barrels (30 tons) of oil per day at 11 knots, giving a range of 19,000 nautical miles.
完全装配后自由轮引擎，高19英尺，长21英尺，重达27万磅。自由轮的4叶螺旋桨直径为18英尺，直接连接到引擎，其设计转数为76转/分，这个螺旋桨转速使自由轮可以达到最高11节的航速。在正常情况下，自由轮的引擎转速为65转/分，在此转速下船速为10节，并且可以节省燃料和延长引擎使用时间。引擎的输出功率为2500马力，在使用11节航速航行时，每日燃料消耗为170桶（30吨），续航力为19000海里。
