Load, Assembly and Pack (LAP) of 60mm, 81mm, and 120mm Full Range Practice and High Explosive Cartridge

The 60mm, 81mm, and 120mm HE cartridges are high explosive munitions developed for use in various mortar systems, including the M224A1, M252A1, M120, M121, and Stryker Brigade Combat Team Mortar Carrier. These munitions are intended for use against personnel and materiel targets, providing fragmentation and blast effects.

Key components provided as Government Furnished Material (GFM) include: Fuzes (M734A1, M783), Fin assemblies (M27, M24, M31), Propelling charges (M235, M236, M220, M658, M234A1), Ignition cartridges (M702, M299, M1020), Shell bodies, Explosive fills (IMX-104, Composition B), Booster materials (PBXN-12).

60mm HE Cartridges:

The 60mm M768A1/M720A2 cartridges represent an Insensitive Munition (IM) upgrade to the M768/M720A1 cartridges, which were originally materiel released in 2006. The M768A1 HE Mortar Cartridge consists of a M783 point detonating/delay fuze, while the M720A2 uses the M734A1 multi-option fuze. Both cartridges use four (4) M235 propelling charges, M27 fin assembly, M702 ignition cartridge, and HF-1 steel shell body. The shell body is filled with insensitive munitions explosive 104 (IMX-104) and includes a PBXN-12 auxiliary booster. The propelling charges are horseshoe-shaped containers filled with propellant around the fin assembly, which can be removed based on the range distance to the intended target. Legacy Composition B variants of these rounds may also be solicited.

The 60mm High-Explosive Enhanced Fragmentation (HE-EF) M1061 Mortar Cartridge consists of the M734A1 Multi-Option (MO) Fuze, M27 Fin Assembly, fin adapter, Obturating ring, four M236 propelling charges, round body assembly (warhead), and M702 ignition cartridge. The warhead includes an aluminum container filled with PBXN-110 explosive, known as the HE unit, which is loaded into a fragmentation insert (FI) made of Liquid Crystal Polymer matrix with preformed metal fragments embedded in the polymer. The FI/HE unit is encased within an outer aluminum case. Variants of the M1061 Mortar Cartridge may also be solicited.

81mm HE Cartridges:

The 81mm M889A4 HE Mortar Cartridge represents an IM upgrade to the M889A2 HE Mortar Cartridge, which was originally materiel released in 2009. The M889A4 consists of M783 point detonating/delay fuze, four (4) M220 Propelling Charges, M24 Fin Assembly, M299 Ignition Cartridge, and HF-1 steel shell body filled with IMX-104 and includes a PBXN-12 auxiliary booster. Legacy Composition B variants of these rounds may also be solicited.

The 81mm HE-EF M821A4 Mortar Cartridge consists of the M734A1 Multi-Option Fuze, M24 Fin Assembly, M299 Ignition Cartridge, four M658 Propelling Charges, Obturating Ring, PBXN-14 Auxiliary Booster, and a Warhead Assembly. The warhead assembly includes an HF-1 Steel Shell Body filled with IMX-104 explosive and a Liquid Crystal Polymer (LCP) matrix with preformed fragments. Variants of the M821A4 Mortar Cartridge may also be solicited.

120mm HE Cartridges:

The 120mm M934A1/M933A1 Mortar Cartridges consist of M734A1 Multi-Option fuze for M934A1 and M783 Point Detonating/delay fuze for M933A1, four (4) M234A1 propelling charges, steel shell body, M31 Fin Assembly, M1020 Ignition Cartridge, Composition B or IMX explosive, and a PBXN-12 or CH-6 Auxiliary Booster. The propelling charges are horseshoe-shaped containers filled with propellant around the fin assembly, which can be removed based on the range distance to the intended target.

Practice Mortar Cartridges:

The 60mm M769, 81mm M879A1, and 120mm M931 FRPC cartridges consist of a hollow shell body with no energetic fill and, except for the color, look identical to the HE cartridges. These cartridges utilize a center vent tube to allow the fuze signature to be vented through a series of holes in the aft shell body. The practice fuze produces a flash, bang, and/or smoke signature upon ground impact, providing audio and visual feedback for training operations. The FRPC cartridges are packed into fiber containers and wooden wirebound boxes.

The U.S. Government intends to solicit the LAP of 60mm, 81mm, and 120mm FRPC/HE cartridges and award up to four (4) Firm Fixed Price (FFP), Indefinite Delivery Indefinite Quantity (IDIQ) contracts to support U.S. Army, Marine Corps, and Foreign Military Sales (FMS) requirements.
