A spigot mortar consists mainly of a solid rod or spigot, onto which a hollow tube in the projectile fits—inverting the normal tube-mortar arrangement. At the top of the tube in the projectile, a cavity contains propellant, such as cordite. There is usually a trigger mechanism built into the base of the spigot, with a long firing pin running up the length of the spigot activating a primer inside the projectile and firing the propellant charge. The advantage of a spigot mortar is that the firing unit (baseplate and spigot) is smaller and lighter than a conventional tube mortar of equivalent payload and range. It is also somewhat simpler to manufacture. Further, most spigot mortars have no barrel in the conventional sense, which means ammunition of almost any weight and diameter can be fired from the same mortar. FR230 Intucompound is a gypsum based mortar used to reinstate the fire resistance performance of floor & wall constructions where they have been breached with apertures for the penetration of single or multiple services. FR230 provides a safe working platform for loads up to 2.5 kN/m² when installed in full accordance to our Ammunition for mortars generally comes in two main varieties: fin-stabilised and spin-stabilised. Examples of the former have short fins on their posterior portion, which control the path of the bomb in flight. Spin-stabilised mortar bombs rotate as they travel along and leave the mortar tube, which stabilises them in much the same way as a rifle bullet. Both types of rounds can be either illumination ( infrared or visible illumination), smoke, high explosive, and training rounds. Mortar bombs are often referred to, incorrectly, as "mortars". [25]

The PFP FR EX fire resistant mortar will also maintain the acoustic design performance of surfaces. Where plastic pipes pass through the mortar, our pipe wraps should be used and can be easily added through the mortar and resealed with further mortar. Supplied in a 20kg bag, the mortar is easy to sand or drill, dries an off-white colour and is suitable for painting once cured. Gábor Ágoston (2005).

ISBN 9780521303583.A mortar is usually a simple, lightweight, man-portable, muzzle-loaded weapon, consisting of a smooth-bore (although some models use a rifled barrel) metal tube fixed to a base plate (to spread out the recoil) with a lightweight bipod mount and a sight. They launch explosive shells (technically called bombs) [1] in high-arching ballistic trajectories. Mortars are typically used as indirect fire weapons for close fire support with a variety of ammunition. Stephen Turnbull (2002). Siege Weapons of the Far East (2): AD 960–1644.

What Is Fire Cement Made Of?

A mortar can be moved around by one or more people (bigger mortars can usually be broken down into parts) or moved around in a vehicle. An infantry mortar can usually be set up and fired from a mortar-carrier. A mortar-carrier is a modified armoured vehicle or one built especially to be a mortar-carrier. They have a big hatch on the roof. Mortars with two barrels—like the AMOS PT1—are the latest kinds of heavy mortar. They are put on carriers such as armoured personnel carriers, tank chassis and patrol boats. [3] During the Russo-Japanese War, Lieutenant General Leonid Gobyato of the Imperial Russian Army applied the principles of indirect fire from closed firing positions in the field and, with the collaboration of General Roman Kondratenko, he designed the first mortar that fired navy shells.

Mortars are usually smaller and lighter than howitzers and field guns. When the mortar bomb is launched, it descends at a very steep angle (almost straight down). [1] The Infantry Assault Soldier/Pioneer conveys unique skills to the battlefield, he is able to provide mobility, counter mobility and survivability to his Battalion. The ammunition fired by mortars are properly called "bombs". One possible reason for this is that the fins that stabilise the round when it is flying, and the shape of the round makes it look like a bomb dropped from aircraft. [1] The Strix mortar round is a Swedish endphase-guided projectile fired from a 120mm mortar currently manufactured by Saab Bofors Dynamics. STRIX is fired like a conventional mortar round. The round contains an infrared imaging sensor that it uses to guide itself onto any tank or armoured fighting vehicle in the vicinity where it lands. The seeker is designed to ignore targets that are already burning. Launched from any 120mm mortar, STRIX has a normal range of up to 4.5km. The addition of a special sustainer motor increases the range to 7.5km. GMM 120–120 mm Guided Mortar Munition". Israel Military Industries. Archived from the original on 7 April 2014 .

The Company comprises of four Platoons that concentrate on supporting all command courses in their different disciplines, within Waterloo Lines. Modern mortars and their ammunition are generally much smaller and lighter than long range artillery such as guns and howitzers, which allows light and medium (typically, 60mm and 81mm/82mm) mortars to be considered light weapons; i.e. capable of transport by personnel without vehicle assistance.
