This is the kits from HobbyBoss. Nice little kit , the detail on the hull and bridge is excellent , the fitting were pretty good and no putty were needed. Recommended for anyone who want to try on HobbyBoss submarine kit. I can say "you must try and you'll love it".
The first of these two submarines was reportedly planned to be named INS Chakra. In January 1988 India had arranged a three-year transfer of a Charlie-I class nuclear attack submarine from the Soviet Union, also named Chakra. The word comes from the Sanskrit "cakra" meaning "wheel, circle", and sometimes also referring to the "wheel of life".
