The PAC JF-17 Thunder (Urdu: جے ایف-١٧ گرج), or CAC FC-1 Xiaolong (Fierce Dragon; Chinese: 枭龙; pinyin: Xiāo Lóng), is a lightweight, single-engine, multi-role combat aircraft developed jointly by the Pakistan Aeronautical Complex (PAC) and theChengdu Aircraft Corporation (CAC) of China. The JF-17 can be used for aerial reconnaissance, ground attack and aircraft interception. Its designation “JF-17” by Pakistan is short for “Joint Fighter-17”, while the designation and name “FC-1 Xiaolong” by China means “Fighter China-1 Fierce Dragon”.
The JF-17 can deploy diverse ordnance, including air-to-air and air-to-surface missiles, and a 23 mm GSh-23-2 twin-barrelautocannon. Powered by a Guizhou WS-13 or RD-93 afterburning turbofan it has a top speed of Mach 1.6. The JF-17 is to become the backbone of the Pakistan Air Force (PAF), complementing the General Dynamics F-16 Fighting Falcon whose performance it roughly matches, at half the cost. The PAF inducted its first JF-17 squadron in February 2010 and five years later 54 units were in service, and 96 units were on order, to be delivered by the end of 2018.
The airframe is of semi-monocoque structure constructed primarily of aluminium alloys. High strength steel and titanium alloys are partially adopted in some critical areas. The airframe is designed for a service life of 4,000 flight hours or 25 years, the first overhaul being due at 1,200 flight hours. Block 2 JF-17s incorporate greater use of composite materials in the airframe to reduce weight.
The mid-mounted wings are of cropped-delta configuration. Near the wing root are the LERX, which generate a vortex that provides extra lift to the wing at high angles of attack encountered during combat manoeuvres. A conventional tri-plane empennage arrangement is incorporated, with all-moving stabilators, single vertical stabiliser, rudder, and twin ventral fins. The flight control surfaces are operated by a computerised flight control system (FCS), which also adjusts the slats/flaps for improved manoeuvrability. Up to 3,629 kg (8,001 lb) of ordnance, equipment, and fuel can be mounted under the hardpoints, two of which are on the wing-tips, four are under the wings and one is under the fuselage.
The man-machine interface of JF-17 Thunder is kept very simple and flexible at the same time too. The cockpit consists of three Multi functional displays (MFDs) supported by a smart Heads Up Display (HUD). The symbology and functionality of the controls is kept very much similar to SAAB’s Gripen aircraft – an aircraft evaluated by PAF in the past. Implementation of HOTAS (Hands On Throttle-And-Stick) is visible in the design. The commonalty of the cockpit helps in decreasing time and training costs thus making a speedy fighter conversion to the aircraft.

JF-17’s cockpit has three 6X8 inch wide MFDs. The information displayed on all these MFDs is interchangeable and pilot can easily switch information among them.A labeled picture of JF-17’s Heads Up Display (HUD).

The elevated design of this panel also helps in decreasing the sun flare from entering the cockpit.PK-16LE MK16 ejection seat also has an ejection sequencer, which manages the separation time of ejection seat and parachute of the ejectee pilot. The main features of PL-16LE MK16 are the rearward firing headbox, leg restraints and enhanced cushions. Beneath the seat cushions are the pilot’s survival kit which includes a rescue flares, small boat, medicine, food and some other accessories.
Internal armament comprises one 23 mm (0.91 in) GSh-23-2 twin-barrel cannon mounted under the port side air intake, which can be replaced with a 30 mm (1.2 in) GSh-30-2 twin-barrel cannon

CM-102 is a Anti-Radar Missile with range of 100km. It has high hit accuracy and a 80kg warhead. PAF has already inducted the Brazillian origin MAR-1 ARM for its JF-17 fleet.Artistic impression of JF-17 Block-II with in-flight refueling probe. The aircraft is equipped with GBU-12 LGBs and WMD-7 Pod on centerline station with CCS marking.Artistic impression of the JF-17 Block-II formation employing 500kg GB-6 SOW. GB-6 is a 500kg bomb guided with GPS/INS system. It can be used for large-scale ground targets such as vital enemy installations.
JF-17 can carry three external fuel tanks (2x 1100 L under wing and 1X 800 L centerline fuel tank) both Air-to-Air and Air-to-Ground role.
The maximum range (3,000km) in a High-High-High mission profile is achieved in the following configuration:
– Stores: 2 x PL-5E II SRAAM + 2 x SD-10A MRAAM + 2 x 1100 L tank + 800 L tank.
The maximum range (1,200km) in a Medium-Low-Low-High mission profile is achieved in the following configuration:
– Stores: 2 x PL-5E II SRAAM + 4 x 250kg bomb + 2 x 1100 L tank + 800 L tank.

The RD-93 is known to produce smoke trails. The Guizhou Aero Engine Group has been developing a new turbofan engine, the WS-13 Taishan, since 2000 to replace the RD-93. It is based on the Klimov RD-33 and incorporates new technologies to boost performance and reliability. A thrust output of 80 to 86.36 kN (17,980 to 19,410 lbf), a lifespan of 2,200 hours, and a thrust-to-weight ratio of 8.7 are expected. An improved version of the WS-13, developing a thrust of around 100 kN (22,000 lbf) (22,450 lb), is also reportedly under development.
JF-17 Thunder has a modified RD-33 engine capable of producing 79-98kN of thrust.Comparison between WS-13 and RD-33
