BMP II Integrated Missile Simulator

Training of the BMP-2 crew on the present generation of anti-tank guided missiles as well as other gunnery aspects of BMP-2 is essential to ensure operational readiness of Mechanised Infantry unites. With ever increasing cost of live missiles, 30mm Cannon and 7,62mm PKT ammunition, their availability for training has reduced considerably.


Training of the BMP-2 crew on the present generation of anti-tank guided missiles as well as other gunnery aspects of BMP-2 is essential to ensure operational readiness of Mechanised Infantry unites. With ever increasing cost of live missiles, 30mm Cannon and 7,62mm PKT ammunition, their availability for training has reduced considerably. The emphasis on simulator training needs to be correspondingly increased.

To achieve the training objective for BMP-2 crew, an upgradation in stand alone missilery training is sought through ATGM Simulator Konkurs. GSQR for the same has been approved vide GSCPC of Jul 2002. In the phase 2, it is intended to integrate missilery training with the basic gunnery training of BMP-2 for the reasons already explained above.

 

1.1.1.  Concept

The BMP-2 Integrated Missile Simulator is intended to practice and master the skills of AGM, 30mm Cannon, 7.62mm PKT and 81mm Smoke Grenade Discharger system by BMP-2 commander and gunner. To ensure the same, simulator should replicate the turret station of BMP-2 to include various controls, sights and other electronic parts as akin to the real system as possible. Dummy breach block and ATGMs system could be provided to enhance realism of the Turret Sin environment. The simulator should provide simulation of terrain, targets, noises and various effects necessary to ensure complete missilery and gunnery training of BMP-2.

 

1.1.2.  Proposed Service Environment

The BMP-2 Integrated Missile Simulator will be used to impart year round missile and gunnery training to Infantry Combat Vehicle crew in Mechanised Infantry units and School of instructions, in all weather conditions. The crew should be able to perform realistically and in correct sequence all actions relating to engagement of all types of ground and aerial targets with ATGM, 30mm Cannon and 7.62mm PKT likely to be encountered in the battle field. The use of the simulator should ensure retention and enhancement of gunnery skills and objective assessment of trainee's performance. Once in use, the BMP-2 Integrated Missile Simulator will supplement not only existing methods of training but also give a state of art training facility to Infantry Combat Vehicle crews and also help mitigate the adverse impact on op preparedness due to restrictions placed on firing of live ammunition.
