A few months ago in Yellow Sea, China conducted a secret test launch of Julang-2 SLBM, but failed, according to Jan. 25 report by Liberty Times of Taiwan.
The missile with the range of 8,000 km, which can strike U.S. mainland, was mounted on a Golf-class submarine, and launched from underwater. However, after breaking out of water, its booster failed to fire up, and fell back down on the submarine.
The submarine with 83 crews and displacement of 2,880 tons was hit by the missile weighing 10 tons, and was almost sunk. Still it managed to limp back to its base.
Ten years ago, PLAN developed Julang-2 by modifying Dongfeng-31 ICBM, and successfully conducted the surface launch, but a few attempt of underwater launch all failed.
As a result, Type 094(Jin-class) submarine, China's newest model, is so far unable to be equip itself with its own SLBM's, leaving a big hole in China's offensive nuclear capability, according to the newspaper.
They succeeded in the test launch of Julang-1 from Type 092(Xia-class) submarine, hitting a target in Taklamakan Desert, but its range is only 2,000 km and this class of submarine mostly moves within coastal waters, which is why they decided to develop Julang-2.
