This scenario is the second in a series in which some of the Naval Gun weapon types newly developed or being investigated are at you disposal in a large scale exercise between AUKUS members USA (Red side) and combined AU, UK and guest NZ (Blue side).
Here the Blue side has HMAS Hobart played by an Indian type 15B DDG that includes a 127/64 Oto LW mount with extended range and guided Vulcano weapons.
Compare this with the realistic Hobart included in scenario #1 of the King Series (KingASW)
