The modifications included:
The new design did not had a good reception and was only used for reentry vehicle tests. It flew three suborbital missions from Taiyuan LC-1 with two successes and a failure on the final mission. The first launch was on June 1, 1995 and the second one was on November 1997. The final and failed on was on January 3, 2002.[13][14][15] References
