Medium Lift Helicopter (MLH) Also on the anvil is RWRDC’s next big leap into the Medium Lift Helicopter category through the Design & Development of the Indian Multi-Role Helicopter (IMRH) of 13 Ton class to meet the requirement of IAF & Indian Army. Similarly, the Deck-Based Multi-Role Helicopter (DBMRH) of 12.5 Ton class is being developed for Indian Navy and will feature blade folding for ship-deck operations. The preliminary design of the IMRH is nearly completed and the configuration studies for the DBMRH are progressing towards completion.
