受军事战略调整的影响,各国海军普遍把水面舰艇发展的眼光投向驱逐舰、护卫舰这类中型作战舰艇。这是由于舰船设计技术的新概念在中、小型舰船上实现比较容易,建造成本相对于大型舰船低廉。更重要的是当代高新技术发展使得这类中型舰船的武备系统和作战能力大为加强,具有较高的效费比,即使是护卫舰级的新型舰艇亦可遂行远洋作战和三维全方位攻击、防御任务。英国海军出于自身发展及面向中、小国家的水面舰艇市场需要,对新型护卫舰的研究 Influenced by the readjustment of the military strategy, the navies of all countries have generally turned their attention to the development of medium-sized warships such as destroyers and frigates. This is due to the fact that the new concept of ship design technology is relatively easy to implement on medium and small ships, and the cost of construction is lower than that of large ships. More importantly, the development of modern high-tech makes the system and combat capability of such medium-sized ships much stronger and more efficient and cost-effective. Even the new type of frigate can carry out ocean-going operations and three-dimensional all-directional attacks, Defense task. British navy out of its own development and facing the needs of the surface naval vessels in small and medium-sized countries, the study of new frigates
