摘　　要：根据未来CVN-21级新型航空母舰的需要，在改进和完善现有材料和工艺的同时，不断进行新材料、新技术的开发和研究。概述为了减轻整个舰的重量和降低重心所进行的努力，包括船体结构应用高强度高韧性钢；扩大钛铝合金的使用范围；采用轻质LASCOR板与复合材料、泡沫钢；装备电磁弹射器代替蒸汽弹射器等。为了延长使用寿命和提高舰的机动性，研制了先进的甲板防滑涂料和镀层，改进了喷气偏流板。这些新材料、新技术的应用将对舰产生重大的有利影响。According to the needs of new aircraft carrier CVN-21, avaiable materials and process for construction call for a continual improvement. This paper gives a detailed description of efforts which will reduce the weight of the carrier and lower the centre of gravity, by using high strength,toughness steels for ship hull structure ;extending the use of titaninium-aluminium alloy;applying laser welded lightweight sandwich（LASCOR） panel and composite materials and foamed steel; electromagnetic launcher taking place of the traditional steam-driven system. For extending life of service and improving the maneuvrability of the carrier, advanced non-skid coating was developed and jet-blast deflector was improved.
