Mastiff 6x6 MRAP Repair & Overhaul in Ukraine

Mastiff MRAP MRO Services in Ukraine

Bronetech provides maintenance, repair and overhaul (MRO) services for Mastiff MRAP vehicles, developed on the Cougar 6×6 platform and designed for operation in environments with high mine and blast threats.
Due to increased vehicle weight, reinforced armor protection and mission profile, Mastiff platforms operate under sustained mechanical stress, requiring a specialized approach to repair and maintenance.
Service work includes restoration of the armored hull, inspection of the V-shaped blast-protection structure, and maintenance of the Caterpillar diesel engine, Allison transmission and reinforced axle systems.
Particular attention is given to the suspension and chassis as critical elements affecting mobility and survivability.

Overview of Mastiff 6×6 MRAP

Mastiff is a heavy MRAP-class armored vehicle derived from the Cougar 6×6 platform and adapted for enhanced protection levels in high-risk operational environments.
The vehicle is primarily used for troop transport and deployment in areas with elevated mine and IED threats.
Compared to standard MRAP platforms, Mastiff features significantly increased combat weight, which directly impacts drivetrain load, suspension wear and overall maintenance requirements.
The reinforced armored hull and blast-deflecting underbody design impose additional constraints on inspection, repair and structural restoration processes.

Key Technical Characteristics Affecting Repair

vehicle class: MRAP
configuration: 6×6
engine: Caterpillar C7 diesel
transmission: Allison automatic
reinforced axle configuration
combat weight: over 25,000 kg
The Mastiff platform is designed to operate under high load conditions, which significantly increases stress on the powertrain, suspension and structural components.
The V-shaped armored hull is engineered for blast energy deflection, requiring precise inspection of geometry, weld integrity and structural alignment during repair.
The chassis and suspension systems are designed for heavy-duty operation, making regular technical assessment critical to maintaining operational capability.

Common Failure Points and Damage Patterns

During operation, Mastiff vehicles typically require attention to the following areas:
● powertrain components operating under sustained operational loads● drivetrain and transmission systems affected by vehicle mass● suspension and chassis elements designed for high load capacity● armored hull and V-shaped underbody prone to hidden deformation● protected electrical systems requiring inspection after impact or vibration
Due to the nature of combat use, some damage may not be immediately visible, therefore extended diagnostics is required prior to repair planning.
