China's People Liberation Army (PLA) Rocket Force is upgrading its older liquid-fuelled, silo-based Dong Feng-5A (DF-5A, or CSS-4 Mod 2) intercontinental ballistic missiles (ICBMs) to carry multiple independently targetable re-entry vehicles (MIRV), according to US government sources.
根据美国政府的消息来源，中国人民解放军（PLA）火箭部队正在升级其老式液体燃料、东风-5A型仓管式（东风-5A，或CSS-4 Mod 2）洲际弹道导弹（ICBM）去携带多弹头分导再入飞行器（MIRV）。

While not mentioning this missile, on 9 February in his annual 'World Wide Threat Assessment' for the US Senate Armed Services Committee, Director of National Intelligence James R Clapper stated that China "continues to modernise its nuclear forces by adding more survivable road-mobile systems and enhancing its silo-based systems".
尽管没有提到这种导弹，2月9日美国参议院军事委员会在他的年度‘全球威胁评估’上，国家情报总监杰姆斯R克拉珀表示，中国“继续现代化其核力量增加更多的可生存道路机动系统和提高其仓管系统”。

That China has been observed replacing the DF-5A's former single warhead with three warheads "within the past several months" was first reported by The Washington Times on 10 February.
华盛顿时报2月10日最早报道“在过去的几个月里”，中国一直在研究采用三枚弹头替代DF-5A型以前的单弹头。

The new MIRV-equipped warhead bus being retrofitted to the DF-5A is probably the same as that on the MIRV-equipped DF-5B first displayed in China's 3 September 2015 military parade. Both the DF-5B and the upgraded DF-5A probably also carry penetration aids such as decoys and chaff to counter ballistic missile defences.
新的已经安装MIRV弹头载具的DF-5A型或等同于MIRV DF-5B型在2015年9月3日阅兵上首次展示。无论是DF-5B和升级的东风-5A可能还使用突防手段如诱饵和箔条去对抗反弹道导弹防御系统。

In its 2003 China Military Report to the US Congress the Pentagon stated that "China is replacing CSS-4 Mod 1 ICBMs with longer-range CSS-4 Mod 2s. The replacement of all the approximately 20 CSS-4 Mod 1s reportedly will be completed by mid-decade."
在面向美国国会的2003年中国军力报告称，“中国采用射程更远的CSS-4 Mod 2S型替换CSS-4 mod 1型洲际弹道导弹。全部约20枚CSS-4 MOD 1型据说将十年内完成更换。”

The 2009 'Cruise and Ballistic Missile Threat' report of the US Air Force's National Air and Space Intelligence Center (NASIC) stated that the PLA's CSS-4 Mod 2 inventory was "about 20".
美国空军国家航空航天情报中心（NASIC）2009年'巡航导弹和弹道导弹威胁'报告描述，中国人民解放军的CSS-4 Mod 2型库存为“大约20枚”。
