Frigate :
It is a lightweight unit, not very fast but dangerous, it is equipped with the most powerful sonar and hydrophones that certainly make it difficult to appear unnoticed (but it has a small radar range) !!
When you encounter a Frigate you should try to sink it immediately, or escape to the maximum depth (250 m), at the limit of the vertical range of its sonar and its hydrophones.
At shallower depths you must also pay attention to not be detected by his powerful hydrophones, moving very slowly to not be located.
Dimensions : 92 m x 11 m
Weight : 1370 t
Speed : 20 kn
Weapons : guns (up to 7 miles) and depth charges.
Sensors :
Sight : 22.5 NM (day), 6 NM (night) (extended range, locate and identify); 7.5 NM (day), 2 NM (night) (standard range, only locate).
Sonar : 2 NM (horizontal), 250 m (vertical).
Hydrophones : 25 NM (horizontal), 250 m (vertical).
Radar : 6 NM.
Destroyer :
It is a unit a little bigger than a Frigate, with less powerful sensors but much faster.
When you encounter a Destroyer you should try to sink it immediately, or escape to a depth greater than 200 m, beyond the vertical limit of its sonar and hydrophones.
At shallower depths you must also pay attention to not be detected by his powerful hydrophones, moving very slowly to not be located.
Dimensions : 107 m x 10.5 m
Weight : 1692 t
Speed : 37 kn
Weapons : guns (up to 7 miles) and depth charges.
Sensors :
Sight : 24 NM (day), 6 NM (night) (extended range, locate and identify); 8 NM (day), 2 NM (night) (standard range, only locate).
Sonar : 1.5 NM (horizontal), 200 m (vertical).
Hydrophones : 20 NM (horizontal), 200 m (vertical).
Radar : 7 NM.
Heavy Cruiser :
It is a unit big enough, fast enough but with less powerful sonar and hydrophones than Frigate and Destroyer, and it has a standard radar.
Be careful that it is hardly to sink it with a pair of torpedoes, but with the reduced vertical range of its sonar will not be difficult to escape.
Dimensions : 193 m x 20.1 m
Weight : 9850 t
Speed : 32 kn
Weapons : guns (up to 9 miles) and depth charges.
Sensors :
Sight : 30 NM (day), 7.5 NM (night) (extended range, locate and identify); 10 NM (day), 2.5 NM (night) (standard range, only locate).
Sonar : 1 NM (horizontal), 150 m (vertical).
Hydrophones : 10 NM (horizontal), 150 m (vertical).
Radar : 8 NM.
Battleship :
It is definitely the largest warships that will require an abundant dose of torpedoes to be sunk !!
It does not have hydrophones, it has a radar and the range of its sonar is reduced.
Dimensions : 227 m x 31.4 m
Weight : 36727 t
Speed : 28 kn
Weapons : guns (up to 9 miles) and depth charges.
Sensors :
Sight : 30 NM (day), 7.5 NM (night) (extended range, locate and identify); 10 NM (day), 2.5 NM (night) (standard range, only locate).
Sonar : 1 NM (horizontal), 150 m (vertical).
Radar : 8 NM.
Aircraft Carrier :
It is a very large unit, fast enough, with a little sonar, a radar but without hydrophones. It doesn’t have cannons or depth charges, but during day it can launch its fighters !!
It contains 37 fighters and can control up to 5 aircrafts at a time.
Dimensions : 212 m x 34.4 m
Weight : 13190 t
Speed : 25 kn
Weapons : 37 fighters.
Sensors :
Sight : 30 NM (day), 6 NM (night) (extended range, locate and identify); 10 NM (day), 2 NM (night) (standard range, only locate).
Sonar : 1 NM (horizontal), 150 m (vertical).
Radar : 8 NM.
