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) under the LAP contract.

The North American Industry Classification System (NAICS) code for these items is 332993. The Product and Service Code (PSC) is 1320.

To be considered a capable source for this effort, all interested sources must submit a response that provides adequate technical and manufacturing capability to LAP the above-mentioned 155mm HE M795 and M1128 Projectiles.  If a respondent does not have adequate resources (technical, manufacturing, personnel, etc.) available, the respondent must be able to demonstrate their ability to obtain those resources. Respondents should provide the following information which will assist the USG in developing its acquisition strategy:

a) A summary that includes a brief description of the contractor's capabilities to include description of facilities/equipment, personnel, manufacturing process, inspection capabilities and how they directly relate to the 155mm HE M795 and M1128 Projectiles, to include any experience managing procurement of TNT or similar material.

b) A description of existing production capacity, evidence of ability to produce a minimum of 12,000 M795 projectiles and a minimum of 5,000 M1128 projectiles per month, maximum monthly production capacity, and any experience producing these items or similar items in the past.

c) Estimated time to produce the First Article Testing (FAT) samples after contract award and lead time for delivery of the first production lot for the 155mm HE M795 and M1128 Projectiles.

d) Address if manufacturing resources are shared with other item/production lines and identify the approximate amount shared.

e) A description of any investment/facilitization that are on-going or will be required to meet capacity.

f) Provide evidence of quality assurance in order to support this production plan;

g) Provide company name, address, Commercial and Government Entity (CAGE) code, telephone number, email address, technical point of contact, and company size (please specify as either a Large Business, Small Business, Small Disadvantaged Business, 8(a) concern, Woman-Owned Small Business, Historically Underutilized Business Zone concern, Veteran-Owned Small Business, or Service-Disabled Small Business).

A Technical Data Package (TDP) for both the 155mm HE M795 and M1128 Projectiles will be made available to interested parties for this announcement. The TDPs are marked Distribution D (authorized distribution of technical documents to Department of Defense components and their contractors).)  If interested sources want to become certified to receive the Technical Information for this market research notice, they must fill out a registration form to become Data Custodians for their Company.
