反舰巡航导弹（ＡＳＭ）的进步，给水面舰艇的自卫提出了极大的挑战，为了对付这种威胁，就必须研制更复杂、更昂贵的舰对空导弹。以法国ＡＮＳ为代表的新一代反舰巡航导弹，将能在几米的高度上以几马赫的速度掠海飞行，而且可在末段飞行期间实施规避机动。这种威胁实质上已把舰炮系统排除在舰艇自卫手段之外，并且大大地降低了现役导弹系统的作战能力。在过去二十年的发展中，高能化学激光器似乎已成为舰艇自卫问题的一种可行的解决办法。高能激光武器系统可在所有天气（除大雾外）条件下有效地工作，可以攻击任一种跟踪到的目标，不需要常规的火控系统。再者，一旦射束导向仪捕获到目标，系统就不再受目标机动的影响。只要光激射周期满足威胁的条件，高能激光武器系统的有效Ｐｋ实质上就是１。把化学能用作主要能源，就不需在舰上装设昂贵而笨重的发电设备。舰载高能激光武器系统用于实战所需的技术已由ＮａｖｙＭｉｄ－ＩｎｆｒａｒｅｄＡｄｖａｎｃｅｄＣｈｅｍｉｃａｌＬａｓｅｒ（ＭＩＲＡ－ＣＬ，舰用高级中红外化学激光器）和ＳｅａＬｉｔｅＢｅａｍＤｉｒｅｃｔｏｒ（ＳＬＢＤ，ＳＬ射束导向仪）所证实。１９８９年，该系统曾成功地击毁一枚速度为２．２马赫的Ｖａｎｄａｌ导弹。最近的研究表?
Advances in anti-ship cruise missiles (ASM) pose great challenges to the self-defense of surface ships. In order to deal with this threat, it is necessary to develop more complex and more expensive ship-to-surface missiles. The new generation of anti-ship cruise missiles, represented by the French ANS, will be capable of swept the sea a few meters at a few Machs and will be able to maneuver during the final flight. This threat has essentially eliminated the naval gun system from the means of self-defense of naval ships and has greatly reduced the combat capability of active missile systems. In the past two decades of development, high-energy chemical lasers seem to have become a viable solution to the issue of self-defense of ships. High-energy laser weapon systems work effectively under all weather conditions (except for fog) and can attack any kind of tracked target without the need for a conventional fire control system. Again, once the beam director has captured the target, the system is no longer affected by the target maneuver. As long as the lasing period satisfies the threat condition, the effective Pk for a high-energy laser weapon system is essentially one. Using chemical energy as a primary source of energy eliminates the need to have expensive and bulky power generation equipment on board. The technology required for real-world applications of carrier-based high-energy laser weapon systems has been demonstrated by NavyMid-InfraredAdvanced ChemicalLaser (MIRA-CL) and SeaLiteBeamDirector (SLBD, SL Beam Guidance). In 1989, the system successfully destroyed a Vandal missile at Mach 2.2. Recent research table?
