Propulsion equipment: Difference between revisions

Afterburners and microwarpdrives both have 10-second cycle times, and cannot be deactivated prematurely. However, the cycle time of afterburners can be reduced to a minimum of 7.5 seconds by training the skill {{sk|Afterburner}}. Capital ship-sized afterburners and microwarpdrives have 20-second cycle times instead. These modules do not have cooldowns, and can be left running continuously, provided capacitor energy is available.

=== 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.

Such fits are sometimes described as "6MN", "60MN", or "600MN" (referring to the size of the two propulsion modules added together).

However, this power comes at a risk: prop mods generate more rack heat than any other modules, and microwarpdrives in particular have extremely severe head damage values. A 5MN MWD, for instance, can completely burn itself out in as few as ''three'' overheated cycles, severely damaging any tackle modules being run alongside it along the way. Very unusually though, the heat damage inflicted by prop mods vastly decreases at larger sizes, to the point that a 100MN afterburner can potentially be overheated for over a minute and a half before being in danger of burning out.

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.

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

* A Micro Jump Field Generator moves not only the ship itself but also most objects which are within 6 km of the boosher. Up to 25 ships will be carried along.

** [[Drones]], [[fighters]], [[bombs]], and [[Interdictors#About the "bubble" (Warp Disrupt Probe)|Warp Disrupt Probes]] will also be moved, and will not count towards the 25-ship limit.  

* [[Warp Scrambler|Warp scramblers]] prevent the boosher or its targets from being jumped.  

** Any target that is scrammed will not be jumped

=== 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]].
