By Manjeet Negi: A Delhi-based laboratory of the Defence Research and Development Organisation (DRDO), Centre of Fire, Explosive and Environment Safety (CFEES), has designed and developed a vertical shaft-based underground ammunition storage facility.
The trial of the storage structure was successfully conducted on April 30 in the presence of the Armed Forces by detonating 5,000 kg of TNT in one of the chambers of the underground facility.
This facility is designed to ensure an explosion within which will not cause damage to the adjacent chamber and also ensure full operability of the remaining facility. The facility is aimed at enabling upward vertical dissipation of blast effects, considerably reducing the blast effect on surrounding utilities.

All the parameters recorded during the trial matched estimated values, as per the CFEES.
The Armed Forces find it difficult to stock ammunition as required by them due to the non-availability of adequate land as large safety distances are required for the storage.
The safety distances are considerably reduced when ammunition is stored underground.
Based on trials, the safety distance has been established; up to 120 metric tons of ammunition storage per chamber. The design has the additional advantage of reducing safety distances and costs by 50 per cent as compared to current designs. The design also ensures a higher safety of ammunition stored from any kind of aerial attack or sabotage.
