ATTENTION: Behaving quite stable now though, this stuff is still under development.

Remember to read and follow ALL manuals below, and use it at your own risk.

Naval Artillery System(NAS) is basically an expansion of the amazing BahamutoD's BDArmory, providing a set of naval weapon replicas and weapons used to attack naval ships from both side in WWII. It is still WIP, and not so detailed, we would improve that soon. PERHAPS

The pack is now under development of a modding team named Kerwis, members of which are all from China. I am honored today to post this small expansion to you all!

Special Thanks: harpwner (for his wonderful firing effects)

REQUIRES: BDArmory Continued v1.2.0 or later. Older versions are not supported.

Version for Kerbal Space Program 1.3.0

Released on 2017-06-25 (FIX) - "Crossroads"

Special thanks to forum user fitiales, for his Spanish localization texts!

  • Updated part list.
  • Tweaked overheating rate of 10 cm/65 Type 98 Naval Gun.

Any medium to large caliber weapon (larger than 75 mm) would have a deviation that would match the average length of the same class ships at the edge of effective range.

Side cannons, except 15.5 cm/60 3rd Year Type Naval Gun Triple Turret (cruiser gun), would use a destroyer template, large caliber AA guns use 2/3 of maximum range as effective range.
