The nominal weight of the bomb is 1,000lb (454kg), although its actual weight varies between 985lb (447kg) and 1,030lb (468kg), depending on fuze options,[1] and fin configuration.[2] The Mk 83 is a streamlined steel casing containing 445lb (202kg) of tritonal high explosive. When filled with PBXN-109 thermally insensitive explosive, the bomb is designated BLU-110.
The Mk 83/BLU-110 is used as the warhead for a variety of precision-guided weapons, including the GBU-16 Pavewaylaser-guided bombs, the GBU-32 JDAM and Quickstrike sea mines.
The Mk 83 is also used as the warhead in a variety of Pakistani smart bombs made by GIDS. During Operation Swift Retort in 2019, 2 JF-17 Thunders of the No. 16 Squadron "Black Panthers" armed with newly developed Mk. 83 Range Extension Kit (REK) bombs struck military targets in Indian Held Kashmir.[3][4][5]
This bomb is most typically used by the United States Navy but is used by the USAF in the F-22A in a JDAM configuration. According to a test report conducted by the United States Navy's Weapon System Explosives Safety Review Board (WSESRB) established in the wake of the 1967 USS Forrestal fire, the cooking-off time for a Mk 83 is approximately 8 minutes 40 seconds.
Alan Warnes (19 March 2020). "Operation Swift Retort one year on". KeyMilitary.com. The JF-17s were each armed with two 1,000lb (454kg) Mk83 Indigenous Range Extension Kits (IREKs) that became operational in 2017. Developed, integrated and qualified by Pakistan-based Global Industrial & Defence Solutions (GIDS), the IREK has a range of up to 37 miles (60km). GIDS has converted Mk80-series general-purpose bombs into satellite-aided inertial navigation system (GPS/INS) guided bombs with a tail unit incorporating aerodynamic control surfaces and glide wings. It provides the JF-17 with a very potent day and night capability to engage a variety of targets.
