This article should be cleaned up or improved. The reason is: unspecified

Propulsion modules are a way to trade off capacitor energy in your ship that allows it to gain an advantage in ship positioning and speed. These advantages are based on what type of propulsion module you are using and the type of ship you are flying. Certain ships require certain size afterburner to function properly or heavily favor certain types of modules with hull bonuses.

Afterburners and micro warp drives

Afterburners (AB) and micro warp drives (MWD) are the basic propulsion modules most hips use. They both greatly increase ship's max velocity. Generally afterburners increase maximum speed by around 150% while micro warp drives increase maximum speed by 500%.

Disatvantages of micro warp drives are high capacitor usage and additional penalty to capacitor capacity, they are shut down by warp scramblers and are generally harder to fit.

There are different sizes of propulsion modules based on basic ship hull size. Using an undersized afterburner on a larger ship will cause the speed boost to become much smaller.

A rough guide:

  • 1MN/5MN = Frigate/Destroyer
  • 10MN/100MN = Cruiser/Battle Cruiser, Industrials
  • 100MN/500MN = Battleship+
  • 1000MN/5000MN = Capital

The max velocity bonus listed in module info is only one factor in actual velociy increase. The maxiumum velocity of a ship useing a propulsion module is

V_max = V_base × V_bonus × ( Thrust / mass )

In practice tha last thrust/mass term is almost equal to one when using properly sized propulsion module and the new maximum velocity is just base velocity multiplied by velocity bonus of propulsion module.

Oversized afterburners

It is possible to fit ships with oversized afterburners: 10MN on frigate/destroyer or 100MN on cruiser/battlecruiser. The high fitting requirement of larger afterburner usually makes this harder to do.

In this case the full maximum velocity formula needs to be used.

Generally the resulting maximum velocity is close to normal sized micro warp drive but the added bonus is that the oversized afterburner is not shut down by scramblers. Thre drawback is greatly increased ship mass which makes manouvering harder.

Micro jump drive

The Micro Jump Drive (MJD) is a propulsion module that instead of making the ship move faster it jumps the ship forward 100km in the direction it is facing. Upon arrival, the ship maintains its direction and velocity. Warp scramblers can be used to disrupt the module.

Micro jump drives can be used only on t1 and t2 battleships, combat battlecruisers, command ships and deep space transports. Marauders gain specific bonus encouraging use of this module.

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

MJD operation

When the module is activated the module spools up for 12 seconds. During this time the ship can not change its direction. The signature radius of the ship is also increased by 150% during the spool up time.

The jump is interrupted if the jumping ship is warp scrambled when spool up time ends. Bubbles, warp disruptors and warp core stabilisers have no effect on micro jump drives. Active bastion module also prevents the ship from jumpint. Deactivating the module during spool up time has no effect.

After 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 module enters 180 seconds long cooldown period that must pass before the module can be used again. Even if the jump fails the module will enter cooldown period.

Micro jump drive field generator

Micro jump drive field generators (MJDFG) are similar to micro jump drives. But instead of jumping only one ship MJDFG jumps all ships in 6 km range of the ship using the module.

Only command destroyers can use micro jump field generators.

Operation of MJDFG is almost idetical to MJD operation. The only difference is that it jumps all ships in 6 km radius. Scramblers can also prevent their targets from getting jumped. This way the ship with MJDFG and some of the ships near it can be jumped while others stay in their places.
