Top Speed Calculation Guide

Editor's Note: This is an advanced guide, and assumes a solid understanding of both EVE-Online and basic algebra. The following concepts, while extremely useful to understand, are not critical.


The list of things that affect your "cruising" speed, i.e. before you've turned an afterburner or microwarpdrive on is:

• Base speed of ship
• Overdrive Injector Systems, Nanofiber Internal Structures and/or Expanded Cargoholds equipped (low slot modules)
• Level of navigation skill (5% per level of skill)
• Level of racial ship skill where applicable, e.g. 5% per level of Racial Industrial skill on industrial ships
• Implants that effect velocity, e.g. Hardwiring - Eifyr and Co. 'Rogue' CY-1
• Bonuses from leadership skills and gang assist modules (I won't be going into too much detail on these as I'm not that familiar with them)

Cruising speed = (base speed of ship + increase/decrease from Overdrives/Nanofibers/Expanded Cargoholds) * (1 + navigation skill level * 0.05) * (1 + racial ship skill level * x applicable) * (velocity implant(s)) * (gang skill/warfare module bonus(es))

E.g.

Sigil, with navigation 4, acceleration control 2, Amarr Industrial 3, a local hull conversion nanofiber structure I, and a CY-1 hardwiring implant.

• Base speed of ship = 155m/s
• Local hull conversion nanofiber structure I gives 24m/s velocity increase
• Sigil gets a 5% per level velocity bonus from Amarr Industrial skill
• CY-1 implant gives a 3% increase to top speed

Cruising speed with these skills and modules applied

= (155 + 24) * (1 + 4 * 0.05) * (1 + 3 * 0.05) * 1.03

= 247.02 m/s

That's all pretty straightforward, the part that isn't as simple is when considering afterburners and microwarpdrives. Apart from the factors that affect the cruising speed, listed above, there are additional factors that decide what the top speed with a particular afterburner or microwarpdrive equipped are. These are:

• Base boost provided by the AB or MWD
• Level of acceleration control skill (5% per level of skill)
• Base mass of ship
• Size of speed boost module (1MN/10MN/100MN)
• Implants that affect microwarpdrive/afterburner boost, e.g. Hardwiring - Eifyr and Co. 'Rogue' MY-2
• Plate(s) fitted

The size of the speed boost module actually determines two variables: the thrust of the module and the mass that is added to the mass of the ship when the module is activated.

• 1MN modules give a thrust of 1,500,000 N and add 500,000 kg to mass
• 10MN modules give a thrust of 15,000,000 N and add 5,000,000 kg to mass
• 100MN modules give a thrust of 150,000,000 N and add 50,000,000 kg to mass

The size and quality of the plate also adds a certain amount of mass to the ship. This has two effects - makes the ship accelerate slower, and lowers the maximum velocity of the ship when a speed module is activated. It does not affect the cruising speed of the ship.

Boosted speed (i.e. the top speed when the boosting module is active)

= Cruising speed * (1 + (base boost of AB or MWD * (1 + accel control level * 0.05) * (ab/mwd implant(s)) * (thrust / (ship mass + modules mass)))


= (base speed of ship + increase/decrease from Overdrives/Nanofibers/Expanded Cargoholds) * (1 + navigation skill level * 0.05) * (1 + racial ship skill level * x applicable) * (velocity implant(s)) * (gang skill/warfare module bonus(es)) * (1 + (base boost of AB or MWD * (1 + accel control level * 0.05) * (ab/mwd implant(s)) * (thrust / (ship mass + module mass)))

E.g.

Thorax with navigation 5, acceleration control 4, a Mark I Modified SS Nanofiber Structure, a 1600mm Reinforced Titanium plate, a Y-T8 Overcharged Hydrocarbon I Microwarpdrive, a CY-1 implant.

• Base speed of ship = 180 m/s
• Base mass of ship = 12,000,000 kg
• Mark I Modified SS Nanofiber Structure adds 21 m/s
• CY-1 implant gives 3% bonus to velocity
• Y-T8 Overcharged Hydrocarbon I Microwarpdrive gives a base boost of 525% (thrust = 15,000,000 N, additional mass = 5,000,000 kg)
• 1600mm Reinforced Titanium Plates I adds 3,250,000

Boosted speed = (180 + 21) * 1.25 * 1.03 * (1 + (5.25 * 1.2 * (15,000,000 / (12,000,000 + 5,000,000 + 3,250,000)))

= 258.7875 * (1 + 4.667) = 1,466.4625 m/s
