Russia delivered the first regimental set of S-400 Triumf advanced interceptor-based Air Defense Systems (NATO reporting name: SA-21 Growler) to China under a 2014 government-to-government contract, an unnamed Russian official told TASS news agency on April 3. He said “Two vessels[???] have delivered the first regimental set of S-400s from the port of Ust-Lug, Leningrad Region, to China within the time limit established by the contract. It includes a command post, radar stations, launching stations, energy equipment [sic] and other property.” Additionally, the source noted that part of the S-400 equipment destined for China has been damaged during transport and returned to Russia: “The work continues, and the missing equipment is expected to be delivered to the customer in the summer.”

(Comment: China placed an order for four to six Russian-made S-400 regimental units in 2014 for an estimated $3 billion. The exact number of S-400 units to be delivered has not been publicly confirmed to date. It is also unclear what missile types Russia has sold to China for the air defense systems.)
