PERFORMANCE SECTION GUIDELINES
1.  Write a brief intro paragraph of 1-3 sentences.
2.  Write 1-3 paragraphs of "meat".  Talk about what the ship does well, what it doesn't, how it compares to same tier ships of the same type, how it compares to the previous ship in the tech tree, whatever.  Try to avoid quoting vital statistics to players unless it is really relevant (i.e. concealment); they can see those in the sidebar on the right and don't need them read back.  
3.  Write a brief summary paragraph of 1-3 sentences highlighting the key takeaways from the paragraphs above.

<h4>Performance:</h4>

''{{#var:ship_name}}'' is the tech tree Tier VI U-boat for the German submarine branch. As an introductory submarine, she is equipped with only homing torpedoes and has access to {{Reserve Battery Unit}}. 

<h4>Hull:</h4>

''{{#var:ship_name}}''’s survivability is low, with an HP pool of 11,500. Her armor is nonexistent, with her entire hull covered in 16mm. Players should be careful not to be spotted on the surface for extended periods of time, as she will suffer heavy damage. 

''{{#var:ship_name}}''’s maneuverability and concealment are very good at helping her survive in battle. Her turning radius and ruddershift are good, at 420m and 4.14 seconds respectively, which aids in dodging depth charges. Her concealment, at 5.65 km, is very good for her tier (outspotting almost every destroyer in her matchmaking spread).

She has an average 27 knot top speed on the surface, alongside a 13 knot underwater speed. While her surface speed is good, her underwater speed is slow, meaning careful positioning is vital in order to not be stuck in bad situations where her speed will not bail her out. Her speed is not enough to outrun destroyers and her hull can be vulnerable to depth charges if the player is not careful. 

''{{#var:ship_name}}''’s Dive Capacity recharge and depletion rate are standard for her tier, at 1 unit/sec each. Her Dive Capacity reserve is high, at 230 units, allowing her to stay underwater for nearly 4 minutes. Her time underwater can be extended with the Reserve Battery Unit consumable which stops the depletion of Dive Capacity for 30 seconds per consumable. This gives ''{{#var:ship_name}}'' an extra 90 units of dive capacity time. 


<h4>Armament:</h4>

''{{#var:ship_name}}''’s sonar is a helpful tool for dealing damage. While the velocity is average at 500 m/s, the 11.5km of range, and fast reload time of 6.5s is enough to double ping reliably. The double ping lasts 50 seconds which allows ample time for homing torpedoes to arrive.

Homing Torpedoes

As a Tier VI submarine, ''{{#var:ship_name}}'' only carries homing torpedoes as her torpedo armament. The homing torpedoes have best in tier range at 11.5km. They deal a respectable 7,533 damage, have a good speed of 76.65 knots, and have a 31% chance of flooding. 

While she gets no access to conventional torpedoes, the fast speed and short arming distance allow the homing torpedoes to be used at close ranges against all targets, especially when shotgunning. Shotgunning is the act of closing distance to a target (around 2-3 km) and launching torpedoes at it, often heavily damaging or destroying low-health ships. Due to having 4 bow torpedo tubes, shotgun attacks will not deal as much damage in comparison to her successors (a maximum alpha strike of 30,132 damage), but the lower health and torpedo damage protection of Tier V and Tier VI ships allows her to comfortably deal high damage to targets. ''{{#var:ship_name}}'' also gets a single rear torpedo tube, which can be used to finish crippled targets from behind. Her torpedoes all reload at the same time, at 50 seconds. 


<h4>Consumables:</h4>

''{{#var:ship_name}}'' has a standard {{Damage Control Party}}, with three stock charges and a short 5 second duration time. Players should be careful not to quickly exhaust their limited charges or will rapidly lose HP to flood and fire damage. 

Her Hydrophone is useful for tracking the location of surface ships while underwater. It lasts 30 seconds, has an 7km range, and has an 80 second reload time

''{{#var:ship_name}}''’s Submarine Surveillance is improved, with a much longer range of 9km. This aids her in detecting enemy submarines from further distances.

''{{#var:ship_name}}'', as a German submarine, gets access to the Reserve Battery Unit.

<h4>Gameplay:</h4>

''{{#var:ship_name}}'' is limited by only having homing torpedoes, but can still deal effective damage in any situation to any target. Players should use her speed and concealment to gain advantageous positions to utilize her homing torpedoes from range or close the distance and “shotgun” targets. 

When pinging targets from range, it is important to utilize her ruddershift in order to dodge depth charges sent at the approximate locations of pings. Double pings will yield more hits, but exposes the submarine's approximate position from repeated pings. This playstyle can also yield less damage due to players using damage control on pings and dodging homing torpedoes by turning away. Once enemy ships are aware of a submarine's relative location, the submarine players' effectiveness shrinks, as the enemy ships will take evasive maneuvers to avoid taking massive torpedo damage.
An alternative way is to fire torpedoes and not use pings, which keeps the submarines position relatively hidden and allows for surprise torpedo hits. 

When closing distances to shotgun targets, players should primarily approach battleships and cruisers. Once at around 6km, players should dive to periscope depth and further close distance. Players should quickly launch all torpedoes before proximity detection (2km) and dive quickly to avoid detection. Players can also ping destroyers at close range as the homing shut off distance is short for destroyers (240m)

Against enemy submarines, her Submarine Surveillance consumable helps in spotting targets and her homing torpedoes can devastate unaware submarines. When fighting enemy subs, it is important to note that they can also use Submarine Surveillance to spot the player back, which can lead to unavoidable damage from depth charges. 

Due to having much lower health and lower alpha strike, ''{{#var:ship_name}}'' can be effective in a supporting playstyle, screening allies for torps, spotting destroyers/submarines, and forcing enemy ships to use their Damage Control Party. It is important to not get caught too deep in enemy lines by submarine surveillance or destroyers, as it can lead to a quick trip back to port. 

''{{#var:ship_name}}'' is an entry level submarine, as her damage output is limited to homing torpedoes. She does not have many weaknesses that prevent her from being effective in most situations. Her biggest strengths are her low concealment and access to the Reserve Battery United consumable, which can aid in staying underwater to evade detection during shotgun attacks or when escaping detection range. The combination of her good maneuverability characteristics and low detection aids in the shotgunning playstyle. Players can find success in both long range homing torpedo attacks and shotgunning targets at close ranges.
