Six specialised production units forming the industrial backbone of Pakistan's indigenous defence manufacturing — from heavy tank rebuild to cutting-edge R&D, all under one roof at Taxila.
Each production unit at Heavy Industries Taxila is purpose-built, independently capable and tightly integrated — together forming a complete, self-reliant defence manufacturing ecosystem.
The oldest and largest unit within HIT, the Heavy Rebuild Factory is responsible for the complete overhaul, upgrade and remanufacture of Pakistan Army's Main Battle Tank fleet, including the Al-Khalid, Al-Zarar and T-series platforms.
Dedicated to the design, development and series production of Armoured Personnel Carriers and security vehicles. The APC Factory delivers platforms including the M113 variants, the Talha APC and the complete Mohafiz security vehicle series.
Specialist unit for the manufacture and qualification of tank guns, artillery barrels and associated ordnance. The Gun Factory produces the 125mm smoothbore gun for the Al-Khalid MBT, along with a range of artillery systems for the Pakistan Army.
The intellectual engine of HIT, the Research & Development Centre drives Pakistan's indigenous defence technology agenda. From fire-control systems and composite armour research to autonomous systems studies, the Centre underpins HIT's long-term self-reliance mission.
The precision manufacturing backbone of HIT, producing critical sub-assemblies, machined components and specialist parts for all other production units. Houses state-of-the-art CNC machining centres, casting, forging and heat-treatment capabilities.
An integrated network of support infrastructure that keeps the entire HIT complex operational — including central warehousing, logistics, power generation, quality control laboratories, test ranges and field service engineering teams.
Established in 1971 as HIT's founding unit, the Heavy Rebuild Factory (HRF) is where Pakistan's most advanced armoured fighting vehicles are born, rebuilt and upgraded. It houses 1.2 million sq ft of production floor space and a workforce of over 4,000 engineers and skilled technicians.
From design brief to field-ready platform — HIT's integrated production process ensures quality, precision and timeliness at every stage.
R&D Centre defines the platform concept, engineering parameters, and materials specifications in close coordination with the customer.
The CMF produces precision-machined parts, castings and sub-assemblies to tolerances as tight as ±0.005mm on 5-axis CNC centres.
Hull fabrication, armour plate integration and structural welding are performed by specialist teams in the HRF and APC Factory.
Powertrain, fire-control, communications and protection systems are installed and calibrated against programme specifications.
Every platform undergoes rigorous in-plant testing, test-range trials and customer acceptance inspection before delivery.
