Kaminami-2

The Kaminami-2 (かみなみ-2) is a Yamataian second-generation  (SLBM) deployed on the Yamatai Imperial Navy's Unryū-class submarines. It succeeds the Kaminami-1 SLBM, also previously deployed on the Unryū-class, albeit with questionable operability.

The Kaminami-2 provides Yamatai with its first viable sea-based nuclear deterrent.

Development
The Kaminami-2 is a naval variant of the land-based Kamikaze-4. Their common 2-metre diameter solid fuel rocket motor was successfully tested in late 1993, and research and development efforts were reorganised starting in 1995 to produce both missiles. The first Kaminami-2 at-sea launch occurred in 2009 from the submarine Unryū. The program was delayed due to the 2010 Masukan War. Successful launches occurred in 2012. Another test launch occurred in January 2015. Deterrence patrols with Kamikaze-2 missiles began in December 2015.

During the development of the missile, it was reported that Yamatai was considering modifying the missile to accommodate an anti-satellite warhead to give it a sea-based anti-satellite capability.

As of 2019, 48 Kaminami-2 launchers are deployed on submarines.

Characteristics
The Kaminami-2 is a three-stage, solid-fuelled missile, with a maximum range of 7,200 km. Its payload is a single 1 Megaton warhead or 3-8 MIRVs with yields of 20, 90, or 150kt.
