The Defence Research and Development Organisation (DRDO) has developed indigenous armour panels that are 20 percent lighter than existing systems while stopping 30 mm armour piercing (AP) ammunition. The panels were developed by the Research and Development Establishment (Engineers) in Pune and meet STANAG 4569 Level 6 protection. They are meant for future main battle tanks, light tanks and Future Infantry Combat Vehicles.
What Is DRDO and Which Lab Developed the Panels?
The Defence Research and Development Organisation (DRDO) is the research and development wing of the Ministry of Defence. It develops weapons, sensors and combat systems for the Army, Navy and Air Force. The new armour panels were developed by its Pune laboratory, the Research and Development Establishment (Engineers).
DRDO was formed in 1958 by merging the Technical Development Establishments of the Army with the Defence Science Organisation. The organisation works under the Department of Defence Research and Development and is headquartered at DRDO Bhawan in New Delhi. Today DRDO operates a network of around 41 laboratories along with five Young Scientist Laboratories that cover aeronautics, armaments, missiles, electronics, combat vehicles and life sciences.
The Research and Development Establishment (Engineers), known as R&DE (Engineers) or R&DE(E), is based in Pune, Maharashtra. The laboratory focuses on combat engineering systems for all three services. Its past work includes military bridging systems, mine warfare equipment, launchers for weapon programmes and ground support systems. In recent years the laboratory has also worked on robotics, composite products and advanced hull structures for combat vehicles.
What Is Armour and What Are Ballistic Armour Panels?
Armour is a protective covering fitted on military vehicles, ships, aircraft and personnel to block bullets, shells and blast fragments. Ballistic armour panels are modular plates made from steel, ceramics, composites or layered combinations. The DRDO panels use such layered design to stop high speed projectiles while keeping weight low.
The word armour simply means protection. On a tank, armour forms the outer skin that absorbs or deflects the energy of an incoming round. Ballistic protection refers to the ability to stop projectiles in flight, while blast protection refers to the ability to survive mines and improvised explosive devices. Vehicle armour must handle both.
Armour piercing (AP) ammunition is designed to punch through such protection. It uses a hard, narrow core, often made of tungsten or hardened steel, that concentrates force on a small point. A 30 mm AP round is fired from an automatic cannon and carries far more energy than a rifle bullet. Stopping it needs thick, hard materials arranged in smart layers.
Older tanks relied mainly on rolled steel. Steel is tough but very heavy. Modern ballistic panels combine a hard ceramic face that breaks the tip of the incoming round with a tough backing of fibre composite or special alloys that catches the fragments. This sandwich design gives the same protection at lower weight and allows damaged panels to be replaced in the field.
What Is STANAG 4569 and What Does Level 6 Protection Mean?
STANAG 4569 is a NATO standard that defines protection levels for occupants of logistic and light armoured vehicles. It grades protection from Level 1 to Level 6 against bullets, artillery fragments, mines and blasts. Level 6 is the highest kinetic energy grade and requires stopping 30 mm armour piercing rounds.
STANAG stands for Standardization Agreement. It is a common rulebook issued by the North Atlantic Treaty Organization (NATO), headquartered in Brussels, Belgium. STANAG 4569 carries the full title Protection Levels for Occupants of Logistic and Light Armoured Vehicles. The detailed test methods are given in a linked document called AEP-55. Even non NATO countries like India use this scale so buyers, designers and soldiers share the same language for protection.
The standard tests three types of danger. These are kinetic energy threats such as bullets and cannon shells, artillery shell fragments, and mine and blast threats. Levels rise from low to high. Testing checks the type of ammunition, the distance, the angle of hit and the part of the vehicle that is hit. Level 6 testing for cannon fire focuses on the frontal arc, which is the front of the vehicle plus 30 degrees to each side, at a reference distance of 500 metres.
| Level | Kinetic Energy Threat It Must Stop |
|---|---|
| Level 1 | 7.62 mm NATO ball and 5.56 mm NATO ball rifle rounds |
| Level 2 | 7.62 mm armour piercing incendiary rounds |
| Level 3 | 7.62 mm armour piercing rifle rounds with tungsten core |
| Level 4 | 14.5 mm armour piercing heavy machine gun rounds |
| Level 5 | 25 mm armour piercing discarding sabot rounds |
| Level 6 | 30 mm armour piercing and armour piercing fin stabilised discarding sabot rounds |
Level 6 is therefore reserved for frontline combat vehicles that may face infantry fighting vehicles and attack aircraft cannon. Very few materials can meet this grade without making the vehicle too heavy to move. That is why a 20 percent weight saving at this level is treated as a major technical step.
The New Indigenous Panels: 20 Percent Lighter Design to Stop 30 mm Rounds
The R&DE (Engineers) panels are reported to be 20 percent lighter than the current system while meeting the same 30 mm AP protection requirement. DRDO scientists have said the design matches global standards for this class of armour. The laboratory has completed in house ballistic testing and confirmed that the panels meet the operational requirements of the force.
Weight is the central gain. Conventional steel armour can stop heavy rounds but it adds tonnes to a vehicle. Extra weight strains the engine and suspension, increases fuel use and makes airlift and rail movement harder. A lighter panel with equal ballistic protection improves speed, range and agility. It also leaves spare weight for sensors, communication sets, active protection systems and add on mine protection.
The achievement matters because modern battlefields expose vehicles to a wider set of threats. Along with armour piercing bullets and cannon shells, crews face anti tank guided missiles, rocket propelled grenades, mines, improvised explosive devices and armed drones. No single plate can stop every weapon. Designers therefore build layered protection where light, high hardness panels handle cannon fire and other systems handle missiles and top attack drones. A lighter base armour gives designers more freedom to fit those extra layers without crossing weight limits.
Where Will the Panels Be Used: Tanks and Future Combat Vehicles
DRDO has positioned the new panels for future main battle tanks (MBTs), light tanks and Future Infantry Combat Vehicles (FICVs). An MBT is the Army heavy tank built for direct battle. A light tank is a nimbler, lower weight tank built for mountains and rapid deployment. An infantry combat vehicle carries soldiers into battle while giving them cannon and missile fire support.
India operates a large fleet of armoured vehicles and is now renewing it. The Wheeled Armoured Platform (WhAP) 8x8, developed by the Vehicles Research and Development Establishment with Tata Advanced Systems, is already inducted in infantry protected mobility and paramilitary roles. In April 2026 DRDO also rolled out the Advanced Armoured Platform, in tracked and wheeled versions, at VRDE Ahilyanagar. Both platforms use a 30 mm crewless turret and aim for high power to weight ratio, speed and STANAG level protection. The new lightweight panels can fit into such programmes as base or add on armour.
Light weight is especially valuable for high altitude service. The Army has deployed large numbers of tanks and infantry combat vehicles in Ladakh and other mountain sectors after 2020. Thin air reduces engine power and soft ground limits movement. Officers have noted that a lighter yet strongly protected system adds a new dimension to mountain warfare because it preserves mobility without sacrificing crew safety.
Transfer of Technology and the Push for Self Reliance
R&DE (Engineers) has offered the manufacturing technology to Indian industry through the Transfer of Technology (ToT) route. DRDO placed the item on its ToT list on 1 October 2026 as Manufacturing Technology for STANAG-6 (30 mm AP) Armour Panels. The offer is listed as Category A with three licences available for industry partners.
Under this system DRDO shares the bill of materials, manufacturing process, quality checks and test schedules with selected firms. The firms then set up production lines and supply panels for vehicle programmes. Senior scientists have said several leading companies have already shown interest. The next stage will involve industrial production and trials on specific vehicle types.
The move supports the national goal of self reliance in defence, popularly called Make in India and Atmanirbhar Bharat. India has long imported specialised armour steel and composite packs. Local design and local production cut import dependence, build a domestic supply chain for ceramics and composites, and allow quick changes to suit Indian terrain and threats. For private firms, access to proven DRDO technology lowers research cost and helps them enter the armoured vehicle market.
