The submarine launched version of the Gale-III ICBM, the next generation HCS ballistic weapon, has been successfully tested for the first time. SeaGale Development Build 1 was launched from the HCS' main missile test site in Micom, a launch from underwater is not expected this year.
A tethered tube will be used in the first underwater test probably next year unless the ballistic missile test submarine CNSS Warhammer is ready.
As for Gale-III itself a final test is expected soon before it is cleared to enter production. The first silos to change from Gale-IIB are expected next year.
