崭露头角的0109型艇人民海军初创时期,东海前线海军依靠一些小型舰艇在头门山海战、夜袭“太平”号、解放一江山岛、炮击金门等战斗中取得了一个又一个胜利。但原有的一些舰艇,如50年代中后期建造的55甲炮艇,虽然比第一代炮艇53甲在战术技术性能上有明显的提高,但此时,国民党海军在美国的扶植下也有了很大的发展,拥有驱逐舰、护卫舰等数十艘舰艇。这些舰艇排水量大,火力强,航速快：此外,尚有一批快速特务艇经常侵犯和骚扰我沿海。相比之下,55甲炮艇航速仍偏低,火力不够强,抗风能力差,不能更好地和鱼雷快艇协同配合作战,需要设计制造新的高速护卫艇。 Emerging 0109 people in the boat during the navy’s infancy, the front-line naval forces in the East China Sea relied on a number of small ships to make victories one after another in battles such as the naval battle at Toumen Hill, the night-tapping “Taiping”, the liberation of a Jiangshan Island and the bombardment of Kinmen. However, some of the existing ships, such as the 55-gun gun built in the mid-1950s, have significantly improved their tactical and technical performance over the first-generation gunboat, but at this time, the Kuomintang Navy also had very good support from the United States Large development, with destroyers, frigates and other dozens of ships. Large displacement of these ships, firepower, fast speed: In addition, there are a number of fast porter boats often violated and harass me along the coast. In contrast, the 55 A gunboat speed is still low, firepower is not strong enough, poor wind resistance, can not be better coordinated with the torpedo speedboat operations, the need to design and manufacture of new high-speed escort boats.
