作战样式和使命任务的变化对军事装备的发展具有牵引作用。传统的两栖作战样式主要是集中在沿海沙滩直接抢滩登陆发起攻击,因而坦克登陆舰占有重要的地位。进入21世纪,超视距攻击、超视距离速登陆、远征作战成为其核心内容,给两栖舰的发展指明了新的方向,提出了新的要求。美国海军“黄蜂”级两栖攻击舰堪称世界海军两栖战转型期的典型装备。飞机运用能力和装载能力成为各国设计、建造两栖舰最重要的关注点,21世纪以来一批多用途两栖作战舰艇建成服役。其中,以美国“圣安东尼奥”级两栖船坞运输舰.英国的“湾”级登陆支援 Changes in operational style and mission have a traction on the development of military equipment. The traditional amphibious combat style is mainly concentrated in the coastal beach beach landing direct attack, so tank landing ship occupies an important position. Into the 21st century, over-the-horizon attacks, over-the-horizon speed landing, expeditionary operations become its core content, to the amphibious ship's development pointed out a new direction, put forward new requirements. The United States Navy “Hornet ” class amphibious assault ship called the world naval amphibious warfare period of the typical equipment. Aircraft utilization and loading capacity have become the most important focus of design and construction of amphibious ships in various countries. A number of multi-purpose amphibious ships have been put into service since the 21st century. Among them, the United States “San Antonio ” class amphibious dock ship. British “Bay ” level landing support
