# B-611

The B-611 is a Chinese solid-fuelled short-range ballistic missile (SRBM) developed by China Precision Machinery Import-Export Corporation (CPMIEC). The missile has a maximum range of 150–400 km (93–249 mi).
The B-611 development began development in 1995, and first shown in 2004. A newer variant was shown in late 2006.
The B-611 was sold to Turkey via technology transfer. Further developed into the J-600T Yıldırım and Bora missiles.

## Variants
### B611

Basic variant, with a range of 250–280 km (160–170 mi) and a 500 kg (1,100 lb) warhead.

#### B611M

Upgraded variant of the B-611, with a 480 kg (1,060 lb) warhead and a range of 80–260 km (50–162 mi).

#### B611MR

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.

### P-12

The P-12 is a variant of the B-611. The P-12 has longer strakes, and is believed to be lighter than the B-611 and carry a 300 kg (660 lb) HE fragmentation or blast warhead.
A pair of the missiles may be carried inside a 6×6 wheeled vehicle.
The P-12 was first shown at the 2006 China International Aviation & Aerospace Exhibition.

#### BP-12

The BP-12 is a variant that has satellite guidance, and is considered the first member of the family to branch out from the B-611.

#### BP-12A

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.

#### CM-401

CM-401 is a hypersonic anti-ship ballistic missile developed by the China Aerospace Science and Industry Corporation (CASIC), with a range of up to 290 km (180 mi) and terminal active radar homing guidance.

#### BP-12B

Latest variant, exhibited at the 2016 China International Aviation & Aerospace Exhibition. It uses radar or infrared homing and can hit slow moving targets like ships.

### SY-300

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. Each vehicle can carry either six or twelve SY-300 rockets.

#### SY-400

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. It was briefly displayed for the first time at the 2008 China International Aviation & Aerospace Exhibition. 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.
