155mm Artillery Projectile Load, Assemble, Pack (LAP): M795 and M1128 LAP Sources Sought The United States Army Contracting Command-Rock Island (ACC-RI), Rock Island, IL, on behalf of the Office of the Project Manager Combat Ammunition Systems (PM CAS), is conducting market research to identify sources capable of LAP and delivering both the 155mm High Explosive (HE) M795 and M1128 Artillery Projectiles. At a minimum this effort will include M795 and M1128 Artillery Projectiles (other Artillery projectile configurations may be included in the final solicitation based on U.S. Government requirements). The 155mm HE M795 Projectile is an extended range high explosive artillery projectile used for fragmentation, blast, and mining. The projectile is a hollow, high fragmentation, steel forged shell filled with TNT and a TNT supplementary charge . The projectiles are packed eight per wooden pallet. Government Furnished Material (GFM) for this effort may include M795 Projectile Metal Parts, Flexible Rotating Cover Band, wooden pallets, lifting plugs, and supplementary charges. Bulk TNT must be procured by the offeror. The 155mm HE M1128 projectile is an Artillery Projectile which utilizes a base bleed for range extension. It is a U.S. Government (USG) developed materiel solution to combine the effectiveness of the existing M795 Insensitive Munition (IM) (DA54) and the extended 30km range of the legacy M549A1 High Explosive Rocket Assisted projectile. This is accomplished through technological advancements in available energetics as well as projectile case design. The M1128 can be used for conventional fire support for Harassment and Interdiction, fragmentation, and blast effects. It will be compatible with current 155mm firing platforms (M109 & M777 series Howitzers). The M1128 projectile will produce fragmentation effects versus personnel and light materiel targets. It consists of a high fragmentation steel body and uses a modified M795 ogive which has been streamlined to increase range. The gilding metal rotating band and plastic obturator are identical to those used on the M795. The projectile cavity is filled with IMX-104 and a PBXN-9 supplementary charge. The M1128 also employs a base bleed propellant in the aft section of the round to reduce projectile base drag. The Hydroxyl Terminated Poly Butadiene (HTPB) base bleed propellant utilizes the same formulation as the one found in the M864, molded into a larger grain for increased range extension. The base closure that protects the propellant is also the same as the one found on the M864. The components that may be provided as GFM to the 155mm HE M1128 Artillery Projectile LAP contractor will be the following: the 155mm HE M1128 Artillery Metal Parts Assembly, IMX-104 Explosive, Meltable Fuze Plug, PBXN-9 Supplementary Charge, Flexible Rotating Cover Bands, Base Closure and Wooden Pallets. The projectiles are packed eight per wooden pallet. The Base Bleed will be Contractor Furnished Material (CFM) …
