Jump drives: Difference between revisions

Jump drives are not modules. They are built into the hull of the ship. All ships that contain a jump drive require the {{Sk|Jump Drive Operation}} skill to pilot. The following classes of ship contain jump drives:  

* [[Jump Freighters]]

* [[Black Ops Battleship]]s

Unlike stargates, which are free to use, jump drives require fuel. The jump drive comes with a special fuel bay. The fuel required depends on the faction that constructed the jump drive, and can be produced by refining [[Ice_Mining#Ice_distribution|corresponding ice]]. The respective fuel type for each faction is:  

* The skill {{Sk|Jump Fuel Conservation}} reduces the fuel consumption by 10% per level which means that you use half the fuel at the maximum level of five.

The following table shows the range, base fuel consumption, and fuel capacity of all jump drive-capable ships.

Activating a jump drive has similar constraints to activating a warp drive: jump drives cannot be activated if the ship is either inside a [[Tackling#Warp_disruption_fields|warp interdiction bubble]] (from an [[Interdictor]] or [[Heavy Interdiction Cruiser]], or if the ship has been [[Tackling#Fitting for tackling|warp disrupted]] below a Warp Core Strength of 0. (However, a jump drive can be activated regardless of the jumping alignment.)

The amount of fuel used in a jump can be calculated with the following formula.

== Cynosural Field Types ==

''Cynosure'' (pronounced like "sigh no sure") is a little-used word outside of EVE. It means a guide, or a person or thing that draws attention towards itself. It originates in the ancient Greek name for the North Star, making it a very appropriate term for the cynosural fields of New Eden.

=== Normal Cynosural Fields ===

Ships with a jump drive can only jump to cynosural fields or beacons. Cynosural beacons are provided by a player-deployed navigational structure, the [[Pharolux Cyno Beacon]] (colloquially simply called "beacon" or "cyno beacon"). Cynosural fields are generated or "lit" by the ship module Cynosural Field Generator I. Cynosural fields and their generators are colloquially abbreviated as "cyno". A normal (or "hard") cynosural field can be seen on the overview from any place in the system and is "warpable". Further, it appears on the universe map.

If you want to light a cyno you have to be in a fleet (only fleet members can jump to that cyno) and slower than 500 m/s. After you light the cyno your nominal speed becomes zero but you continue to drift and can also be bumped, but the cynosural field stays at the position, where you lit it. Further, you cannot dock in a station or structure and cannot eject, but you can self destruct. Indeed you can light a cyno after you initiated the self destruct sequence. This is used as a trick for extra safe traveling. The cyno needs several seconds until it appears on the universe map. If you light the cyno shortly before you self destruct and immediately jump to it, you can minimize the risk of being caught. But, be aware that if you jump to a cyno in the same moment as the cyno ship dies, you still jump but you land at the destination system's star, not at the former spot of the cyno.

=== Covert Cynosural Fields ===

Covert Cynosural Fields are a special variant of the "normal" Cynosural Fields discussed above. In a context in which either type might be mentioned, a "normal" cyno is often called a "hard cyno".

Unlike a normal cyno, a Covert Cynosural Field is only visible on the overview if you are on grid and can be generated even in cyno jammed systems. The module to generate a covert cyno is named Covert Cynosural Field Generator and can only be fitted to certain ships. Those are [[Black Ops Battleship]], [[Blockade Runners]], [[Frigate#Covert Ops|Covert Ops Frigates]], [[Cruiser#Recon Ships|Force Recon Ships]], [[Stealth Bombers]], and [[Strategic_Cruiser|Strategic Cruisers]] (with the covert subsystem); further, the single hulls [[Etana]], [[Prospect]], and [[Rabisu]]. As a rule all ships which can fit a covert cloak (except the [[Sisters of EVE]] ships) can fit a covert cyno.  

Only [[Black Ops Battleship]]s can jump and bridge to covert cynos. Black Ops Battleships can only bridge ships which are able to fit a Covert Ops Cloaking Device (it doesn't have to be fitted). Bridges by Black Ops only last 20 seconds. For more details about bridging mechanics see the below [[#Bridging|section]] about it.

=== Industrial Cynosural Fields ===

An Industrial Cynosural Field Generator I works much like an ordinary cyno, but with some key differences. First, it can only be jumped to by [[Jump Freighters]], [[Capital_Ship#Capital_Industrial_Ship:_The_Rorqual|Capital Industrial Ships]] and [[Black Ops Battleship]]s. Of these ships, only Capital Industrial Ships can bridge to it. Second, similar to Normal Cynosural Fields, Industrial Cynosural Fields appear on the Overview when lit. It has a base fuel consumption of 800 liquid ozone per cycle, with a minimum consumption of 400 LO/cycle with Cynosural Field Theory V. Industrial cynos can only be fitted to:

== Bridging ==

A Jump Bridge is a way for a [[Titan]], [[Black Ops Battleship]] or [[Rorqual]] to launch its allies, who cannot use jump drives, across space to where they are required.

Titans can bridge all subcapital ships. Black Ops Battleships can only bridge ships which are capable of fitting the [[Cloaking|Covert Ops Cloaking Device]]. (The ships do not need to have the module fitted in order to use the bridge.) This includes the [[Sisters of EVE]] ships, and [[Strategic Cruisers]] fitted with the Covert Reconfiguration subsystem. Rorquals can only bridge [[Mining Frigate]]s, [[Expedition Frigates]], [[Mining Barges]], [[Exhumers]], and the [[Porpoise]].

The ship with the generator must first be within jump range of a cyno lit by a member of the fleet.

A bridge can be activated if the host ship is in a warp disruption bubble, but ships inside the warp disruption bubble cannot take the bridge, only those outside a warp disruption bubble and who are not warp disrupted below a warp core strength of 0.

A Black Ops Battleship or a Rorqual can instead conduit jump to their respective cyno. This both jumps them and to 30 eligible ships in a 10 km radius to the cyno. Unlike bridging, conduit jumping costs a flat amount of fuel no matter the size or mass of the affected ships, at a base value of 1000 isotopes, making conduit jumping a more efficient way of moving a smaller fleet around. A Rorqual can only conduit jump if its Industrial Core is disabled.

As of the October 2014 Phoebe release, traveling using a Jump Drive, Jump Portal, Jump Bridge, Covert Jump Drive or Covert Jump Portal causes fatigue to capsuleers and a delay is required between successive jumps. This delay is determined by the jump fatigue mechanic. Jump fatigue is presented as a time value, indicating the time it will take to decay to zero, and can accumulate to a maximum of 5 hours. It decays in real time, whether logged in or not. Jump fatigue is recalculated after every jump.
