The latest update adds a new Submarine Torpedo Attack order. Players can now use their wolf packs to sneak up on enemy naval groups, fire torpedoes and retreat. This type of attack can be countered with the presence of Destroyers who have a chance to detect the subs and shoot first. Grouping your naval units takes on greater importance as does the race to gain anti-submarine tech to defeat this lethal combat tactic.
As with land and air units, we've improved naval combat tooltips and group information. A new Out of Fuel Penalty has been added that reduces combat effectiveness when ships run out of Coal or Fuel. This will devalue parking ships in mid-ocean. Additionally, naval units without fuel cannot interdict trade.
We’re also looking at ways to improve player feedback. The Summary Panel now shows the progress of all your Recruitment and Construction projects. We have more plans to develop this area of the UI and we encourage your feedback and ideas.
More naval focused AI, UI enhancements and improvements are planned for the next update.
