The B611MR is a semi-ballistic surface-launched anti-radiation missile first advertised in 2014. It uses GPS-inertial guidance and wideband passive radar. The missile is capable of flying flattened trajectory and performing pre-programmed maneuvers to reduce the chance of interception.[10]
The P-12 is a variant of the B-611. The P-12 has a longer strake,[clarification needed] and is believed to be lighter than the B-611 and carry a 300 kg (660 lb) HE fragmentation or blast warhead.[4]
A pair of the missiles may be carried inside a 6×6 wheeled vehicle.[4]
The BP-12A is similar to the Type 631, with an estimated range of 300–400 km (190–250 mi) and a 480 kg (1,060 lb) warhead. The missile can be integrated into the SY-400 missile launcher.[2][3]
Latest variant, exhibited at the 2016 China International Aviation & Aerospace Exhibition.[12] It uses radar or infrared homing and can hit slow moving targets like ships.[13]
SY-300 is a development of WS-2/3, with SY standing for Shen Ying (神鹰 meaning 'Divine Eagle'), designed after the 4th Academy and the 9th Academy of the China Aerospace Science and Technology Corporation (CASC) were merged to form a new 4th Academy. The main difference between the SY-300 and its WS-2/3 predecessor is that for WS-2/3, the control section of the forward control surfaces and the warhead are integrated into a single unit, but they are separated in SY-300. This design difference enables the guidance system of SY-300 to be rapidly changed in the field by soldiers, by simply replacing the guidance system with a dummy weight, when SY-300 needs to be used as an unguided rocket.[14] Each vehicle can carry either six or twelve SY-300 rockets.
SY-400 is a further development of SY-300 that can carry either two BP-12A short-range ballistic missiles with a range of 400 km (250 mi) or eight 400 mm rockets.[2][15] It was briefly displayed for the first time at the 2008 China International Aviation & Aerospace Exhibition.[2] As a low cost alternative to more expensive ballistic missiles, the accuracy of SY-400 is increased by adding GPS to correct the cascade inertial navigational guidance, and according to the developer, the accuracy can be further improved if military grade GPS signals are used to replacing the existing civilian GPS signal. Another feature of SY-400 is that it shares the same launching vehicle and fire control system of BP-12A ballistic missile, thus simplifying logistics.[16][2]
