Subject: Source Sought Notice for production of Joint Assault Bridge (JAB) chassis

REFERENCE: SAM NOTICE: “JAB-Requirement-Change-Notice” for Notice to Industry on the change in Government requirement from an Authorized Army Objective (AAO) of 297 to an Army Procurement Objective of 213.

Army Contracting Command - Detroit Arsenal (ACC-DTA) is issuing this Sources Sought Notice on behalf of the requiring activity, Project Manager Force Projection (PM-FP) Product Manager Bridging (PdM Bridging), as a means of conducting market research to identify interested parties with resources to support the JAB requirements.

Purpose: The purpose of this notice is to seek information to assess the availability of sources that possess the capabilities and interest in the reduced requirement, for an estimated 18 JAB chassis to achieve the current APO of 213, as identified in the referenced SAM notice above, to produce the Bridge Launch Mechanism (BLM) and integrate it onto an M1A1 (with heavy A2 suspension) Abrams chassis in order to provide JAB chassis, ancillary support including Contractor Logistics Support (CLS) and material. DRS Sustainment Systems, Inc. (DRS) is the developer and Original Equipment Manufacturer (OEM) of the JAB and current the Prime contractor.

Background: The M1110 JAB is an Army Acquisition Category (ACAT) II program replacing the legacy M48/M60 tank-based Armored Vehicle Launched Bridge (AVLB) and Wolverine systems. The JAB system is a fully-tracked armored combat engineer vehicle specifically designed to provide Armored Brigade Combat Teams assault bridging capabilities to support maneuver elements. Using the M1A1 (with A2 suspension) Abrams chassis as the basis for the system, the JAB provides equivalent crew protection and vehicle survivability, while having the necessary speed and cross-country mobility to keep pace with maneuver forces. The JAB launches and recovers the Army’s existing hydraulically actuated Heavy Assault Scissor Bridge (HASB), Military Load Class (MLC) 115.

The Government has a mix of unlimited and Government Purpose Rights (GPR) for the product-level TDP.

Acquisition Timeline: The estimated date for award is 3QFY26.

Production Requirement: The Government has procured 175 JAB chassis from DRS-SSI through FY25 and anticipates procuring an additional 20 JAB chassis in FY26 for a total anticipated quantity of 195 JAB chassis to be procured from DRS-SSI through FY26.

As of July 2025, the Government requirement to achieve the APO of 213 systems is an estimated 18 systems. The remaining requirement to achieve the APO is 18 JAB chassis through FY28.

The JAB program could be constrained by available funding in the Program Objective Memorandum (POM) out years. In addition, the JAB program may be constrained based on multiple factors including available funding provided as well as direct labor rates on a cost-reimbursement basis; currently ANAD is responsible for a complete tear down and repair of the JAB M1A1 (with A2 suspension) chassis. Any increase in cost-reimbursement identified costs or funding cuts will reduce the affordable quantity in any given year and extend the date of completing the APO. Any ensuing contract will require optional coverage to procure the anticipated Government requirements, as well as meet any FMS or emerging requirements.

Associated with the production quantities estimated between FY27-28, supply chain or obsolescence issues associated with utilization of the M1A1 (with A2 suspension) chassis will need to be analyzed by the contractor.

Current Production: The current JAB production time is approximately 12-14 months and is produced in two production stages.

Under stage-one, approximately 8-months; Anniston Army Depot (ANAD) performs all work to produce a rolling chassis, to include the tear-down and repair of the chassis which is funded directly by the USG. The M1A1 (with A2 suspension) chassis is then provided to the current contractor as Government Furnished Material (GFM).

Under stage-two, approximately 6-8 months; the current contractor produces the BLM and integrates the BLM onto the GFM provided chassis and delivers a complete integrated JAB Chassis excluding the HASB.

JAB Specifications:

Weight, Load, Ground Pressure:

Weight, combat-loaded (less kits) with T-158 track

• With MLC 115 scissoring bridge           72 tons (65 metric tons)
• Without MLC 115 scissoring bridge      56 tons (50 metric tons)

Dimensions:

• Length (without bridge)              36.8 ft (11.2 m)
• Length (with bridge)                     42.4 ft (12.9 m)
• Height (without bridge)               9.9 ft (3 m)
• Height (maximum overall)          13.1 ft (4 m)
• Width                                                    13.2 ft (4 m)
• Width (less skirts)                            11.3 ft (3.5 m)

Contractor Logistics Support (CLS) Requirement: The JAB program achieved Full Material Release (FMR) in April 2023; however the Government has incorporated multiple Engineering Changes through Engineering Change Proposals, including Add on Armor (AoA), hydraulic parking brake accumulator, and updated launch control unit. The Government requires CLS support to any newly fielded JAB systems with the Engineering Changes until updated logistics products are authenticated, currently estimated in December 2028.

The result of this market research will contribute to determining the best method of procurement. The applicable North American Industry Classification System (NAICS) code assigned to this procurement is 336992.
