During this year's parade, the most notable weapons on display were the cruise and ballistic missiles. Tanks, self-propelled artillery and other armored vehicles also rolled by while large numbers of fighter aircraft (including the J-15 carrier-based fighter) and helicopters flew overhead. Unlike the missiles, however, no completely new design was included among these formations. Missiles that were previously closely guarded were also shown, such as the DF-16 short-range ballistic missile, the DF-21D anti-ship ballistic missile , the DF-10A land-attack cruise missile and the DF-26 intermediate-range ballistic missile. China, unlike the United States and Russia, is not a party to the Intermediate-Range Nuclear Forces Treaty . The treaty forbids the deployment or development of ground-launched ballistic and cruise missiles with intermediate ranges, defined as 500-5,500 kilometers (300-3,400 miles).
