The Department of Defense Precision Fires and Mortars (PM PFM) organization manages several sizes and variants of Mortar weapon systems. These weapon system products include special kits and standalone hand held electronic devices used to operate these devices. The systems range in size from small man-portable versions like the 60 mm and 80 mm mortars to the 120 mm vehicle mounted and vehicle towed mortar systems. PM Precision Fires and Mortars was formerly known as Product Manager Guided Precision Munitions and Mortar Systems (GPM2S).

Accelerated Precision Mortar Initiative (APMI)
The Accelerated Precision Mortar Initiative (APMI) is precision mortar which uses Global Positioning System (GPS) technology. The XM395 GPS guided 120 mm mortar round is programmed before it’s fired.
APMI Details:
“APMI XM395, cartridge uses a standard M934 high-explosive 120 mm projectile body. In the nose, a GPS receiver and computer controlled aerodynamic directional fins keep the round on its programmed trajectory. Folding fins in the tail provide stability. The APMI also has a multi-functional fuse, which allows the round to be programmed to explode in the air, once it hits a hard surface or after it penetrates inside a target.” According to Peter Burke, PEO Ammunition’s deputy product manager, Guided Precision Munitions and Mortar Systems.
The GPS coordinates are input from the ballistic computers with the addition of a Precision Lightweight Universal Mortar Setter System (PLUMSS). The PLUMSS fire control interface unit is an indirect fire control system that is capable of programming the precision guided 120 mm mortar cartridge which is used with 120 mm smooth-bore, mortar systems such as the ground mounted and Stryker mounted 120 mm mortar systems.
This High Explosive Guided Mortar (HEGM) cartridge gives soldiers in Brigade Combat Teams (BCTs), and Special Operations Forces (SOF) Non-Line-of-Sight (NLOS) capability on the battlefields. It’s programmable by the M95 Mortar Fire Control System or M150 MFCS-D or M32 Lightweight Handheld Mortar Ballistic Computer (LHMBC).
The NSN for the XM395 120 mm High Explosive Guided Mortar (HEGM) cartridge is 1315-01-590-3308.
The NSN for the XM701 Precision Lightweight Universal Mortar Setter System (PLUMSS) is 1290-01-586-5780.
Precision Guidance Kit (PGK) XM1156/M1156
The Precision Guidance Kit (PGK) is a precision guidance fuze that contains Global Positioning System (GPS) guidance for more accurate result. The PGK currently has two Department of Defense Identification Codes (DODIC), NA28 NSN 1390-01-579-0413 for the XM1156 and DODIC NA29 NSN 1390-01-617-0269 for the newer M1156. The PGK currently being procured has the NA29 DODIC. It is adaptable to existing stockpile of M795, M795IM and M549A1 high explosive 155 mm projectiles. Flight data is inductively loaded into PGK using the Enhanced Portable Inductive Artillery Fuze Setter (EPIAFS)
The Product Manager Precision Fires and Mortars several years ago performed a bottom-up technique known as “clean-sheeting” to better understand the cost of the M1156 Precision Guidance Kit (PGK) and to identify opportunities for cost savings. We may touch on this in future articles. One of the initial contract that was awarded to for production of the Accelerated Precision Mortar Initiative (APMI) XM395 was sole source to Alliant Techsystems, ATK (Now owned by Northrop Grumman) contract number W15QKN-10-C-0059.
Mortar Systems
The PM Precision Fires and Mortars product line includes the entire Mortar System everything except the ammo. The mortar systems are the 60 mm, 81 mm, 120 mm towed and mounted mortars.

Doing business with PM Precision Fires and Mortars (PM PFM):
Part of doing business with the military, selling products you manufacture starts at knowing what, why and how they buy. Much of what DOD buys is part of something else, a higher system or end item. The items above are mostly end items and in order to keep them operational, sometimes over the span of 50 years they need a lot of parts. The more knowledge you have on the end items and who uses them will lead your company to better and bigger business opportunities with the Department of Defense.
In addition although a single weapon system may have initially been produced by one prime contractor many other smaller contractors get involved especially when the item currently in use, needs repairs or updating. One weapon system could have 100s or thousands of individual parts that are needed to keep the item in operation – These are known as spares and can be great business opportunities for any government contractor.
