The Defence Research and Development Organisation (DRDO) handed over the Medium Range-Microwave Obscurant Chaff Rocket (MR-MOCR) to the Indian Navy at a ceremony held in New Delhi on June 26, 2024. Microwave Obscurant Chaff (MOC), a niche technology developed by DRDO’s Defence Laboratory, Jodhpur, obscures radar signals and creates a microwave shield around platforms and assets, thus reducing radar detection.
A special type of fibres, with a diameter of few microns and unique microwave obscuration properties, have been assembled in the medium-range chaff rocket. The rocket, when fired, forms microwave obscurant cloud in space spreading over a sufficient area, with adequate persistence time, thus creating an effective shield against hostile threats having Radio Frequency seekers.
The Phase-I trials of MR-MOCR were successfully conducted from Indian Navy ships, demonstrating the MOC cloud blooming and being persistent in space. In Phase-II trials, the Radar Cross Section (RCS) reduction of an aerial target to the extent of 90 per cent has been demonstrated and cleared by the Indian Navy. The number of MR-MOCR, meeting all the qualification requirements, have been successfully handed over to the Indian Navy.
