The DF-25 missile has been successfully researched and developed, is able to launch one or a number of warheads that are equipped with passive infrared terminal guidance. After warheads reenter the atmosphere, they are able to maneuver accurately toward the target.

但是美国海军计划对所有装备“宙斯盾”系统的62艘驱逐舰和22艘巡洋舰进行升级，使其具备弹道导弹防御能力。根据美军计划，到2009年美国海军将拥有18艘装备“弹道导弹防御型宙斯盾”系统的战舰，其中包括15艘驱逐舰和3艘巡洋舰。五角大楼水面战委员会主席维克托•吉尔罗伊少将15日表示，18艘反导宙斯盾舰远不够用，因此计划首先对所有的“阿利•伯克”级导弹驱逐舰进行升级，使其具备拦截弹道导弹的能力。随后22艘导弹巡洋舰的升级也将被列上日程。这对地区和平、尤其是东亚和台海安全构成了严重威胁。

But the U.S. Navy planned to upgrade Aegis system, including 62 destroyers and 22 cruisers for missile defense. According to the Navy plans, it will have 18 sea-based missile defense equipped ships, including 15 destroyers and 3 cruisers. A U.S. Navy committee argued that all Arleigh Burke’s should be upgraded. This presents a serious threat to regional peace, especially for security in East Asia and the Taiwan Strait.

从理论上说，如果美国全部宙斯盾战舰作战系统都升级为“导弹防御型宙斯盾”，这样一支反导舰队集中部署在一个方向，将可以同时拦截500枚以上的中程弹道导弹。

Theoretically speaking, if America assembled all its Aegis assets together, they could intercept more than 500 medium range ballistic missiles at one time.

从拦截区域上看，海基拦截系统覆盖面积是“爱国者-3”反导系统的100倍；从技术成熟度上来看，目前海基拦截系统是美国所有能拦截中程弹道导弹的反导系统中拦截成功率最高的一种。
From the perspective of defended area, sea-based missile defenses cover an area 100 times larger than that of PAC-3. In terms of technology, sea-based missile defenses have had the highest success rates.

所以，东风－25弹道导弹采用了“隐形战术弹头”概念，以减少弹头在实施分导开始阶段的“雷达反应红外线” 特征，使得东风25导弹更加难以拦击。但要确保突破宙斯盾反导系统从而达到击沉航母的目的，还是有很大难度的。

Therefore, the DF-25 incorporates a “tactical stealth warhead” concept in order to reduce the “radar reaction infrared” (awkward wording in Chinese that is hard to translate), when the warhead is in the initial phase of payload separation, and make the DF-25 hard to intercept. But it’s still difficult to ensure the ability of missile to penetrate the Aegis missile defense system and destroy the carrier target.

故中国人民解放军在2006年提出了进一步研制新型弹道导弹，争取在3年内装备3种新型弹（目前定型为：东风25乙 东风26甲 东风26乙三型）。要求采用低轨分导式，既导弹升空后保持在20千米至30千米的低轨道飞行，不必重返大气层，使美军装备的“宙斯盾”海基拦截系统没有充足的反应拦截时间。
In accordance with a 2006 PLA proposal, R&D began on new ballistic missiles to be finished within three years (finalized designs include the DF-25B, DF-26A, and DF-26B). The requirement is to adopt a low trajectory with separable warheads, maintain a 20-30 kilometer altitude in order to not give Aegis destroyers sufficient time to respond.

{{Note: In a version posted on Sina.com a few days after the iFeng article, the language stresses a DF-26 sea-launch variant, rather than the surface-launched DF-25:

其中东风25乙为路基型，东风26甲为海基型，东风26乙的具体情况还不太清楚。

Roughly translated, “the DF-25B is ground-launched, the DF-26A is sea-launched, and specific details of the DF-26B aren’t clear.” }}

野战陆基型低轨分导式“航母末日”反航母导弹（东风25乙）具备隐身和超强抗各种干扰能力，发射准备阶段和距离航母舰队500千米前，利用GPS、北斗系统、低轨侦察卫星、天波雷达、地面监听站等设备对航母舰队进行连续跟踪，以保证飞行方向。距离航母舰队500千米时，弹载雷达设备自动寻的，对目标方位进行修正、定位。
Using stealth and ECCM, the ground-launched “carrier killer” ASBM (DF-25B) relies on GPS, Beidou, LEO satellites, OTH-B, and SIGINT sites to establish a continuous track during the launch preparation stage and up to 500 kilometers from the aircraft carrier group. At a range of 500 kilometers, the missile-borne radar starts its autonomous search for the target, and adjusting its direction and position in relation to the target.

其它性能：

Other Characteristics:

1．导弹母体在飞行中敌方雷达可探测距离小于100千米。
1. Enemy radars can detect the main missile body at a range of less than 100 kilometers.

2．导弹母体在释放出分弹头后，可在战区上空盘旋，为分弹头提供制导，并对航母舰队进行强电磁、电子压制。

2. After the main missile body releases warheads, it can loiter within the theater and provide warheads with guidance as well as conduct electronic countermeasures against the aircraft carrier battle group.

3．导弹母体保持200秒以上盘旋时间。

The main missile body can loiter for more than 200 seconds.

4．导弹母体保持200秒以上盘旋时间后，携带预留高燃剂以10马赫速度、90度直角俯冲攻击航空母舰。

另外，野战陆基型低轨分导式“航母末日”反航弹道母导弹（东风25乙）备有多种弹头

In addition, the ASBM (DF-25B) has several types of warheads:

1．高爆穿甲弹

前段时间国防大学军事专家张教授提出我国目前并不急于建造航空母舰的建议，原因很可能是知道反航母弹道导弹“航母末日”既将问世。

At previous times, NDU Professor Zhang raised that China shouldn’t rush to build aircraft carriers, because perhaps the “final days of the aircraft carrier” are going to become public.

陆基型低轨分导式“航母末日”可有效地将航空母舰阻挡在海岸线1000千米——1500千米外，并对进入“航母末日”有效射程范围内的敌舰予以毁灭性的打击。
Ground-based low trajectory, separable warhead ASBM could effectively prevent the aircraft carrier from crossing a 1000-1500 kilometer line. And also the ASBM will effectively enable us to destroy vessels that come within this range.

{{Note: In the Sina.com version, the final two paragraphs are substituted with the following discussion of the sub-launched DF-26 variant and a torpedo-like payload without any additional detail:

另外具可靠消息透露,中国军方正加紧开发新型“航母末日”专用超高速潜水高爆火箭弹头,取名“龙啸”。预计“龙啸”脱离母弹入水后的速度为500千米，水下航程80千米，爆炸当量达到900千克TNT.

In addition, according to reliable sources, the PLA is developing a special use underwater warhead referred to as the “Longxiao.” It’s estimated that the Longxiao would separate from the main missile body and enter the water at a range of 500 kilometers (Chinese says “speed” though), have an underwater range of 80 kilometers, and have 900kg of explosives.

美军方分析，因潜射型低轨分导式“航母末日”反航弹道母导弹弹体偏大，目前中方只有094型战略导弹核潜艇和在研的095型核攻击潜艇、096型战略导弹核潜艇能够搭载。由于094型、096型战略导弹核潜艇的定位不同，携带“航母末日”的数量在3枚以内；095型核攻击潜艇可携带“航母末日”的数量在8——10枚左右.
