When sending out a Strike Group, you may have a chance to deal with a Sudden Strike, a surprise attack that catches the enemy unawares. If successful, the enemy aircraft will start the battle landed on the ground, sitting targets until launch. The outpost’s garrison will also not have time to transmit your location to the enemy fleet.
The chances of performing a Sudden Strike successfully with your current strike group are indicated in the bottom right of the map screen. Flick any of the three red toggle switches to see the Sudden Strike percentage if the enemy possessed that detection method.
For your best chance at a Sudden Strike, use the ships in your squadron with the highest Speed (SPD) statistics. As you add more ships to the Detachment, your Sudden Strike percentage chance will increase or decrease, so choose the optimum balance.
