How GBU-39 bombs became Israel’s ‘weapon of choice’
1,401–1,500 of 1,690
Analyst Note:
Although this munition started out life as a mortar projectile of the M492-pattern, it has been modified to be dropped from an unmanned aerial vehicle (UAV) and, in its present state, could not be fired from a conventional mortar. As such, it is correctly classified here as an air-delivered bomb. (ARES)
Analyst Note:
The fin assembly in the image bears a strong resemblance to those of other munitions employed in the same incident that have been identified as M49A2 mortar projectiles modified to be delivered by UAV. (ARES)
Analyst Note:
The large fragments in this image are typical of 'natural' fragmentation resulting from the rupturing of a thick-walled munition (in this case, an artillery projectile) by the functioning of its explosive payload. (ARES)
Analyst Note:
This image features both delivered (the two left-most munitions) and undelivered munitions of the same model.
Analyst Note:
Like the more common 9M22S rocket, the 9M28S carries the 9N510 warhead, which dispenses 180 individual incendiary elements composed of a magnesium alloy shell filled with a thermite-like incendiary composition. (ARES)
Analyst Note:
The Brimstone is a series of British-designed guided missiles that can be launched from air, land, or sea platforms. The United Kingdom first provided Ukraine with the Brimstone I missile in 2022 and exports have continued since, more recently believed to include the Brimstone II model. In Ukraine, Brimstone-series missiles have been exclusively launched from ground-based and sea-based platforms as of May 2024. (ARES)
Analyst Note:
122 mm ‘Grad’ rockets can be fired from a variety of launchers and even in improvised ways. The most common is the BM-21 launcher and its later derivatives, but many other portable or vehicle-mounted launchers have been used around the world. Craft-produced examples—ranging from simple rails to more complex designs comparable to factory made launchers—are also common. In some cases, Grad rockets are even fired whilst supported by a crude arrangement of logs, bricks, or rocks. (ARES)
Analyst Note:
This artillery projectile is a non-lethal type designed to carry propaganda leaflets. Externally, it strongly resembles other variants carrying lethal payloads, although this particular model has a distinctive all-red colour. The leaflets are expelled from the base of the munition by the action of a small explosive charge, after a set amount of time has elapsed after firing (determined by the fuze). (ARES)
Analyst Note:
These S-25-O air-to-surface rockets are each loaded into a single-barrelled O-25 rocket launcher (sometimes called a 'launch tube' or 'rocket pod') that is affixed to an aircraft hardpoint. The over-calibre high explosive fragmentation warhead (of 420 mm in diameter) protrudes from the front of the tube. (ARES)
Analyst Note:
As a result of the rapid introduction of new models and variants during ongoing conflicts, sometimes a munition is issued with a provisional designation, or with no designation at all. In other cases, the designation is not yet known to researchers. (ARES)
Analyst Note:
Whilst most mortars are smoothbore guns, some have a rifled bore. These M1101 120 mm mortar projectiles feature a 'pre-rifled' driving band—that is, a driving band with grooves cut at the factory to fit the mortar's rifling.
