- The South Korean navy is pursuing what it calls the "Joint Firepower Ship."
- Borrowing a US concept, the so-called arsenal ship is meant to carry dozens of missiles.

In June, South Korean shipbuilder Hanwha Ocean showcased a model of its "arsenal ship" design at the International Maritime Defense Industry Exhibition in Busan.
It was the latest sign of progress on an ambitious project for which the South Korean navy has notably given few updates on, or specific details about, over the years.
