20世纪后期,对海上舰艇的探测技术和手段有了飞速发展和提高,为了对付这一技术,保证舰艇安全,舰艇隐身技术的开发和研究应运而生。在隐身舰艇制造方面,美国行动最早,法国行动最快,其“拉斐特”级隐身护卫舰90年代初即问世。瑞典虽然立项、研制、试验几乎与法国同步,但是到了2000年6月,第一艘隐身护卫舰方下水。为什么拖后了4、5年,因素有很多。但从瑞典在2000年6月8日下水的“维斯比”隐身护卫舰的性能看,堪称世界一流。“维斯比”护卫舰,是在140吨实验船的基础上发展起来的。当时瑞典海军认为尽管冷战结束了,但实际上海军执行各种任务的数量和性质基本没有变化,因而决定建造多用途护卫舰,又鉴于当前探测与 In the late twentieth century, the technology and means of detecting ships at sea were rapidly developed and improved. In order to deal with this technology and ensure the safety of naval vessels, the development and research of naval stealth technology came into being. In stealth warship manufacturing, the United States acted first and France took the quickest way. Its “Lafayette” stealth frigate was launched in the early 1990s. Although the establishment of the project in Sweden, research and experiment almost simultaneously with France, but in June 2000, the first stealth escort ship launched. Why delayed for 4, 5 years, there are many factors. However, the performance of the “Visby” stealth frigate launched into Sweden on June 8, 2000 is regarded as world-class. The “Visby” frigate was developed on the basis of a 140-tonne experimental ship. At that time, the Swedish Navy believed that in spite of the end of the Cold War, the Navy had virtually no change in the quantity and nature of its various tasks and decided to build a multi-purpose frigate. In view of the fact that current exploration and
