Propulsion equipment: Difference between revisions

Afterburners boost a ship's maximum speed by around 130-200%, while microwarpdrives increase speed by around 500-700%. Compared with afterburners, then, microwarpdrives offer a much greater speed boost. However, they also use more capacitor energy, reduce the ship's total capacitor capacity when fitted, increase the ship's [[signature radius]] when active, can be shut down by [[scram|warp scramblers]], and are generally harder to fit.

=== Sizes and mass effects ===

There are different sizes of propulsion modules, intended for use on different sizes of ships.

The max velocity bonus listed in module info is only one factor in the actual velocity increase. The maximum velocity of a ship using a propulsion module is

In practice, that last thrust/mass term is almost equal to 1 when using properly sized modules on frigates, cruisers, and battleships, and for such hulls the ship's new maximum velocity is about equal to its base velocity multiplied by the bonus of the propulsion module.

==== Choosing afterburners ====

For afterburners, the pattern is fairly straightforward. Higher-tech afterburners grant larger speed bonuses. Faction and deadspace afterburners have lower capacitor costs, and come in two types: one consuming extra CPU ([[Gallente]]/[[Serpentis]]), one consuming extra powergrid ([[Minmatar]]/[[Angel Cartel]]).

==== Choosing microwarpdrives ====

For microwarpdrives, the story is more complex. Higher-tech MWDs grant only minimal speed improvements over lower-tech modules. Instead, higher-tech MWDs carry significantly reduced signature radius bloom effects and capacitor penalties.

As with afterburners, faction and deadspace microwarpdrives come in two types: one consuming extra CPU but with reduced activation cost (Gallente/Serpentis), and one consuming extra powergrid  but with reduced signature radius bloom (Minmatar/Angel Cartel).

It is possible to fit ships with oversized afterburners: 10MN on a frigate/destroyer, or 100MN on a cruiser/battlecruiser. The high fitting requirements and capacitor consumption of the larger AB usually makes this difficult. If this is being done, the full maximum velocity formula needs to be used to determine the ship's actual max speed.

It is theoretically possible to also fit oversized microwarpdrives onto certain ships, but this is extremely difficult and extremely rare.

A ship may only have one afterburner and/or microwarpdrive running at a time. However, it is possible, and commonly done on certain ships, to fit both an afterburner ''and'' a microwarpdrive onto one ship, to exploit both the evasive abilities of an AB and the range control of an MWD.

These overheat effects become especially noticeable on Combat [[Interceptors]], which feature a bonus that increases the overheat speed multiplier to ''100%'', and on ships using oversized afterburners, which will both benefit from the added acceleration, and be able to run their afterburners hot for exceedingly long times.

The following skills directly effect afterburners and/or microwarpdrives.

* {{sk|Acceleration Control}} 5% Bonus to Afterburner and Microwarpdrive speed boost per skill level.

* {{sk|High Speed Maneuvering}} 5% reduction in MicroWarpdrive capacitor usage per skill level.

The '''Micro Jump Drive''' ("MJD") is a propulsion module which, rather than making the ship move faster, teleports the ship forward 100km in the direction it is facing. Upon arrival, the ship maintains the direction and speed it had at the moment of MJD activation. Warp scramblers can be used to disrupt this module.

Micro jump drives can be used offensively to close on a target, or defensively to jump out of a fight.

=== Micro Jump Drive operation ===

When a MJD is activated, the module spools up for 12 seconds (reduced to a minimum of 9 seconds by the skill {{sk|Micro Jump Drive Operation}}). During this time, the ship can not ''voluntarily'' change its direction, though it may unpredictably change course if it bumps into an immovable object. The signature radius of the ship is also increased by 150% during the spool-up time. A ship attempting to activate an MJD gains a visible orange-white rippling cone effect in front of it.

After the spool-up period the ship jumps 100 km to the direction it is facing. The ship retains its velocity and locked targets through the jump. Other ships will also retain locks on the ship that jumped.

After the jump has been completed (or aborted by scrambler) the MJD enters an 180-second cooldown period before it can be used again. Even if the jump fails, the module will still enter its cooldown period. This cooldown period is reduced to 54 seconds on [[Marauders]], allowing them to activate an MJD to move, then activate one cycle of their Bastion Module on landing, and then jump again when the Bastion ends.

Micro Jump Field Generators ("MJFGs" or "booshes") are similar to Micro Jump Drives, but they let pilots move surrounding ships and objects with them.  

=== Mobile Micro Jump Unit ===

Mobile Micro Jump Units may be deployed in space, with modest restrictions on proximity to stargates, stations, starbases or Upwell structures. They allow all nearby ships (within 2.5 km) to jump themselves 100 km away in whatever direction they are facing, by right-clicking the Unit and selecting ''Jump''. Jumping using a Mobile Micro unit has a 12-second spool-up, not reduced by skills, and produces the same orange-white rippling cone visual as using a Micro Jump Drive.

The Mobile Micro Jump Unit is the only source of micro-jumping available to [[Alpha clones]].
