Fans can’t wait to see ASTRO back together, performing and creating music again after all members complete their military service. The group’s military enlistment era began when the oldest member, MJ (Kim Myung Jun), enlisted in 2022.
Nearly three years later, two ASTRO members, Cha Eunwoo and Jinjin, will soon hit pause on their entertainment activities to complete mandatory military service. While Cha Eunwoo military enlistment date has already been announced, Fantagio, ASTRO’s agency, has yet to reveal details on Jinjin’s military service.
After debuting in 2016, ASTRO saw a fair share of ups and downs in their 9-year journey with Rocky’s departure and Moonbin’s passing. Before more members begin military enlistment, all ASTRO members, including Rocky, will reunite for their fourth concert, Stargraphy, in Seoul on June 7-8.
Here’s a comprehensive overview of ASTRO members’ military service status, including confirmed enlistment and discharge dates

A Note on Military Service in South Korea:
All able-bodied South Korean men are required to complete mandatory military service, typically for about 18-21 months, depending on the branch. This is a crucial aspect of national defense and a widely accepted part of life.
