Deathstar
Deathstar is a reference to a popular style of outfitting a POS. A Deathstar POS fitted primarily or exclusively with gun batteries and Electronic Warfare. Because gun batteries require large amounts of powergrid, Amarr Control Towers and Minmatar Control Towers are the most desired towers to be turned into Deathstars.
Usage
Deathstars are most effective against sub-capital fleets, which can have a hard time dealing with the large amount DPS that they use. This DPS can be focused if players with the Starbase Defense Management skill take control of the defences. Because of this Deathstars are often used in Highsec and other systems with Cynosural System Jammers active. They are also used to defend critical structures like Cynosural System Jammers and Jump Bridges.
Deathstars are not suited to situations where capital ships will be present. Dreadnoughts, Supercarriers and Titans are very effective at incapacitating the defences of even the deadliest Deathstar with little threat to themselves. In such situations a Dickstar setup may be preferable in order to delay the destruction until friendly reinforcements arrive.
