This battle group was under the command of Rear Admiral P Ajit Kumar, Flag Officer Commanding, Eastern Naval Command. According to the Ministry of Defence, the two-month deployment, far from India's usual area of operations, along with naval exercises with a number of countries, aimed to demonstrate the Indian navy's operational reach. During the deployment the battle group participated in passage exercises with the navies of the countries visited. The 'Passage Exercises' focussed on maritime security cooperation, which included humanitarian aid & disaster relief (HADR) operations and 'visit, board, search and seizure' (VBSS) drills for anti-piracy operations. These exercises aimed to increase naval inter-operability, enabling the two navies to function together smoothly during possible HADR operations.
