L16 mortar consisting of barrel, base plate and bipod Looking down an L16 mortar barrel. Note: fixed firing pin. Most modern mortar systems consist of four main components: a barrel, a base plate, a bipod and a sight. Modern mortars normally range in calibre from 60 mm (2.36 in) to 120 mm (4.72 in). However, both larger and smaller mortars have ...
The mortar had a firing pin in the bottom of the tube. When the shell was dropped down the tube, the firing pin struck the ignition cartridge in the shell's tail, detonating it. When the cartridge detonated, the explosive gases exited the base of the shell through two bleed holes. This propelled the shell out of the tube in an arc.
Because of this, the Army started the Accelerated Precision Mortar Initiative (APMI) from an urgent operational needs statement in February 2009 [citation needed] to create a GPS-guided 120 mm mortar with accuracy of 5 m (16 ft) CEP at 7,000 m (4.3 mi); because APMI was an urgent request, it was accelerated by an Other Transaction Authority ...

Reports of M240 mortar use became scarce after 2012, possibly because of depletion of munitions stock, but in 2015 and 2016 the exploded casings of two dozen rocket-assisted 3O8 240 mm shells were identified in the suburbs of Damascus, as well as in East Ghouta and Douma, accompanied by un-exploded O-10 fragmentation cluster munitions, which ...
The design of the M-37 is based on the earlier French Brandt mle 27/31 mortar with Russian modifications. [5] The main difference between the 82-PM-37 and the earlier 82-PM-36 was the adoption of a round base plate, revised traverse/elevation controls, simplified sights and spring-loaded shock absorbers on the bi-pod to reduce the amount of ...
The Type 97 81mm infantry mortar was essentially a straight copy of the Brandt 81mm mortar with only a few Japanese-specific changes that differentiated the type from French and American derivatives. The Type 97 81mm mortar used Type 98 and Type 100 HE rounds, use of smoke and illumination rounds was restricted to larger trench mortar types.
In September 1917 under-secretary of state for inventions sent a circular letter requesting inventors to design a better projectile for the successful Stokes mortar, and Brandt scaled his 60 mm projectile up to 81 mm. [10] Both British and French military adopted the scaled-up design except for the grooves (apparently, their importance wasn't ...
