Abhay (Sanskrit: अभय, "Fearless") is an Infantry Combat Vehicle (ICV) being developed in India by the Defence Research and Development Organisation (DRDO). Abhay is being developed as a technology demonstrator for replacing Indian Army BMP-2s. At present, various systems of this vehicle are in advanced stages of development.[1] On 18 November 2013 India conveyed to Russia that they will not shelve their homegrown $10 billion Futuristic Infantry Combat Vehicle (FICV) programme in favour of Russian BMP-3 combat vehicles during the meeting of the India-Russia Inter-Governmental Commission on Military Technical Cooperation held in Moscow.[2]

Project

Abhay serves as a pre-technology demonstrator to develop and test technologies that will be used on a futuristic ICV (FICV), which will replace the Indian Army's BMP-2 vehicles.[3] The project started in the late 1990s, and design work was completed by 2001.[4] However, the project faced delays due to US sanctions imposed after the Pokhran-II Nuclear tests.[5]

Abhay is being developed by the DRDO’s Ahmednagar-based Vehicles Research & Development Establishment (VRDE). A Mild Steel (MS) prototype of the Abhay has been built, and is being tested for proving automotive systems. The pre-production prototype was rolled out in June 2005. Development of the first armoured prototype is also in progress.

Design

Firepower

Abhay features an all-electrical turret drive system and a 40 mm high-velocity cannon capable of firing APFSDS and High explosive rounds.[6]

The anti-air firing range of the 40 mm cannon is 4 km and 2.5 km for ground attack. The ICV comes loaded with a total of 210 rounds of ammunition, and its turret, housing a thermal imager using the Catherine FC, also contains a twin-launcher for the Kornet-E ATGM (anti-tank guided missile). The Abhay is operated by a crew of three, and carries seven infantry soldiers. An electro-mechanical all-electric drive (AED) for weapons control with independent stabilisation has been developed indigenously by DRDO in association with private sector industry for the turret. The purpose of the AED is to position the 40 mm cannon on to the target in azimuth and elevation and to provide twin-axis turret stabilisation against external disturbances.

The AED uses brush-less drives with especially designed backlash-free elevation and traverse gearboxes coupled to the turret ring for rotation in azimuth, and to sector gears for elevation/depression of the cannon, respectively. The AED also employs vector-control technologies implemented through digital controllers and insulated gate bipolar transistor (IGBT)-based power amplifiers for control of the brush-less drives. It also uses fibre-optic gyros as feedback elements for the purpose of stabilisation. AED has a provision for MIL-STD-1553B databus and RS-422 interfaces for real-time connectivity.

Mobility

Abhay is powered by a Greaves Cotton TD2 V8 410 kW (550 hp) diesel engine (a power-to-weight ratio of 24 hp/tonne) and an automatic gearbox supplied by L-3 Communications. The hydro-pneumatic suspension allows for increased passenger comfort. These factors will give Abhay excellent mobility and speed.

The DRDO's Defence Bioengineering and Electromedical Laboratory (DEBEL) based in Bengaluru is designing the ergonomical layout of Abhay.[7]

Protection

Abhay is fitted with NBC protection system and Laser warning detectors.

Armour

Abhay is equipped with composite armour. Two prototypes were built. The first one was with the steel armour and the second one was fitted with the composite armour. The composite armour reduces the weight by 40% compared to steel. Lighter ERA has been developed to be used on the Abhay.
