A Chinese Wu Gong Chuan is more or less equivalent to a sixteenth century Mediterranean galia sottil. It has more than forty oars and three hundred sailors (including oarsmen and marines). Its deck length range from seven zhang five chi to ten zhang.
Wu Gong Chuan is armed with thirty-four Fo Lang Ji (佛狼機), which are categorised into light, medium and heavy cannons. Light cannon only weigh one hundred and fifty catties, medium cannon weigh five hundred catties and heavy cannon weigh one thousand catties. The heavy Fo Lang Ji is capable of shooting eight catties cannonball, roughly equivalent to a 10-pounder gun. This is in contrast to contemporary Mediterranean war galley, which is often armed much heavier (50-pounder or more) ordnance.
Mediterranean war galley was superior to Chinese war junk of the time, as evidenced by Ming defeat suffered at the hand of the Portuguese. The Chinese had to resort to long siege, fire ships and divers in order to finally defeat the Portuguese at the Battle of Tãmão (even then, three out of four Portuguese ships escaped). After Chinese reverse-engineered the Wu Gong Chuan and Fo Lang Ji, they were able to defeat the Portuguese much more easily at the Second Battle of Tãmão.
