This item is currently being replaced by the Lightweight Handheld Mortar Ballistic Computer RPDA 57, manufactured by General Dynamics.  TAMCN and ID listed in the table below.  The US Army is the Primary Inventory Control Agency (PICA) and replaced the previous model in 2009.

Previous Model:

MBC will automate technical Mortar fire direction and replace the M16 and M19 plotting boards as the primary means of computing 60mm and 81mm mortar firing data. The end state MBC system will consist of a ruggedized handheld device utilizing the latest Windows based operating system to host the Mortar Ballistic Kernel software. This stand-alone system will be fielded to 60mm mortar sections at the infantry company level, and 81mm mortars at the infantry battalion. Approximately 623 units will be acquired, plus spares.

The LHMBC is a small, lightweight, portable, battery powered data entry terminal and computer used for automated computation, digital communication, and display of mortar-related information. It sends and receives digital information within the Tactical Fire Direction System (TACFIRE), communicating with the Digital Message Device (DMD) through standard Marine Corps communications radios or field wire.  Coined "Merlin".

E06717M M777 LIGHT WEIGHT HOWITZER

The LW155 is the world's first 155mm howitzer with a flyweight of less than 9800 pounds with digital fire control. Designed as artillery support for the Marine Corps and Army Light Forces, the LW155 is air transportable by medium or heavy lift helicopters, the V-22 tilt rotor aircraft, and other tactical transport aircraft. The LW155 offers greater ground mobility and improved reaction times, compared with the greater than 16,000 pound M198 Howitzer it is designed to replace. It also offers significant advantages in the areas of automatic breech opening and primer feed, and crew ergonomics.

E06657M M198 HOWITZER MEDIUM TOWED

The M198 Howitzer provides the user with a towed system that is air transportable, has high reliability and availability while greatly increasing the effective range of towed weaponry. It provides significant improvements in lethality, range, reliability, availability, and rapid emplacement and movement over its predecessor, the M114A1, which was fielded in World War II. The M198 is air transportable by transport aircraft and the CH47C Helicopter. The weapon is designed for use with new ammunition, such as the Copperhead and rocket assisted projectiles, as well as other 155mm standard projectiles and propelling charges. The gun/ammo system complies with the quadrilateral (US, FRG, UK, Italy) ballistic standardization agreements. en rotated 180 degrees and it should be noted how far the reticle in the telescope has moved up or down from its original position.
