近年来,世界上许多国家都非常重视发展155毫米口径的火炮系统,以将其作为21世纪战场上的主用武器。但是由于各国的技术基础、设计、研制和生产能力各不相同,因而所发展的155毫米火炮也都带有各自不同的特点。我国155毫米火炮的优点尤其突出。从牵引到自行国产PLL01 155毫米牵引式火炮是我国利用多年来在研制牵引式和自行式火炮过程中积累起来的丰富经验与技术成果,同时借鉴国外同类火炮的先进技术而研制成功 In recent years, many countries in the world have given great importance to the development of a 155-millimeter artillery system that will serve as the main weapon on the battlefield in the 21st century. However, because of the technical basis, design, development and production capacities of different countries, the 155-mm artillery developed has its own unique characteristics. The advantages of our 155 mm artillery are particularly outstanding. From traction to self-made PLL01 155 mm towed artillery is China's use of many years in the development of traction and self-propelled artillery accumulated during the rich experience and technical achievements, at the same time learn from the advanced technology of similar foreign artillery and successfully developed
