Revision as of 03:20, 17 June 2011
Notes on data below:
- Naval assets can only be directed by FAO
- Naval assets fire in salvos/broadsides based on their number of guns
- Mission stats calculated by firing for Maximum duration until rounds complete. This gives the cyclical average rate of fire. As stated though generally salvos are fired so shells arrive in a relatively close group, then pause depending on RoF until next salvo arrives. However at heavy RoF for DD for example the actual salvos seem pretty continuous! If the rounds per min is less than salvo size likely there will be at least a minute gap between salvos.
- Duration stats again reflect the salvo characteristics. On anything more than Harass RoF and Maximum Duration then most fire missions will be over in under 1-2mins. For a longer fire mission (given the relatively long delay to set up) then maybe a good idea to call Harass/Short RoF for maximum duration and then ceasefire when you feel the enemy has a big enough headache. Beware Heavy/maximum as all rounds will be expended in 2-3mins (though that will be impressive boost to friendly forces morale! popcorn anyone?)
- Ships are cruising several miles offshore thus even in pre-prepared missions add approx 30secs flight time for rounds to land on target.
- If you select point target on a building once it is destroyed the mission will cease fire. Even 14in doest seem to breach bocage though...
- Beware safety friendly forces distances for the heavy stuff. BB shells particularly have a danger area of at least 150m to troops in the open and drop shorts do happen...
- Ships names included for scenario building purposes. DD List not complete I think but CL, CA, BB are complete for USN although some other RN ships provided support from time to time.
