Tips for beginners: Shields and Armour

elite_noobOkay, so I am assuming you have done the basic tutorial missions. You haven’t? Well, do them! No arguments. They teach you the basic basics. What’s the difference between this and those? The same difference between driving lessons and road experience. One gets you a licence, the other keeps you alive afterwards.


When you fly around in a ship in Elite: Dangerous there are two things saving you from the bullets and lasers of those pesky pirates. Shields and hull armour. Your shields are a semi-visible barrier that blocks energy and matter from hitting your ship, preventing most damage. Your hull starts with a basic level of armour that prevents incoming weapons from damaging your ship. Better armour can take more damage.


Your shield is an energy bubble that protects you from a fixed amount of damage (measured in Mega Jules "MJ") from weapons fire. When it isn’t being hit, it will recharge at the rate of 1.6MJ per second from your "SYS" systems power capacitor. If the shields are drained, they collapse and the hull will start taking damage. You see your shields displayed as three blue rings around your ship hologram on the Heads Up Display (HUD).

Ship power systems

When your shields have collapsed, they must be recharged to half their total capacity before they come back up. This means the bigger your shields the longer they last, but the longer you are without them once they collapse. This means you have a choice of keeping them light with a faster recharge or “tanking” and hoping to outlast an opponent by having the bigger shields.

The exception are Bi-Weave shield generators. These come only in C rating in all class sizes. They have the same resistance as standard shields, but recharge at 2.4MJ/s (roughly 1.5 times faster).

There is also one other type of shield currently. Prismatic shields. These are only available to rank 3 power player members of Aisling Duval’s faction after four weeks. Prismatic shields are 20% stronger than standard, but draw a lot more power and weigh more. They are like a shield with an A rated booster built-in. Why use them? They free up a utility slot on your ship if you are short, to add more shield boosters or other things, like Chaff launchers or Kill Warrant Scanners.

Shields often come in one class size that is the default for your ship, but a higher class may be fitted (or lower if weight and power are an issue) but the caviat for this is the shields only work for a maximum hull mass, so like other modules, if you fit shields too small for your ship, they will not function. You cannot fit multiple shield generators. Sorry.

The examples below are of one model of each shield type fitted to a Cobra Mk III (the most common ship in the game).

Shield types

Hull armour

Your basic ship hull comes with lightweight armour. This has a “Hit Point” value, which indicates the amount of damage it can take before it fails. Buying better armour (or Hull Reinforcement modules) will raise this value. There are also two derivatives of the top-end armour that make your hull more resistant to thermal damage (lasers) or kinetic damage (bullets).

The examples below are of one model of each bulkhead type fitted to a Cobra Mk III.

Armour types

Armour is expensive. Military grade composite will cost as much as the ship you are fitting onto! Another thing to be aware of, is weight. The extra hull will reduce your jump range, which is why most fighters can’t jump very far.

Hull Reinforcement

Armour is a way of making your ship tougher, but hull has to be repaired when damaged (unlike shields which recharge) and is one of the things you can only fix at a station. You can also add armour into module slots with "Hull Reinforcement Packages". This upgrades are not as effective as bulkheads, but add a lot of armour and can be used to fill any free internal slot with armour. What difference does this make? Well if you've got some cash to splash on it, a lot. Spend 3M CR and you'll get a pretty tough ship. See below.


Both ships look the same from the outside, but it's clear who will last longer in any conflict.

Obviously you don't have to add these upgrades all at once, but as you can see there is a large scope for incremental improvement of your ships hull and shields. No ship can be made indestructible, but you only have to be a bit tougher than the other guy. A bit of extra shield or hull might mean the difference between making the jump to hyperspace or being slain by those pirates.

Shield recharge times in Elite: Dangerous

shields_thumbAfter a bit more research I have found some of the theory behind shield recharging.

The value of 0.9 MJ/s on a 3E Power Distributor on a Cobra is the rate at which systems recharge shields. The default shield generator is a 4E with 93.58 MJ total strength. In theory therefore, a 4E shield should take 104 seconds (93.58 / 0.9) to recharge.
A class 3A Power Distributor pumps out 1.3 MJ/s, so the same shield with an A rated distributor should take 72 seconds.

Until I’ve tested this theory, I cannot be certain, but it follows that the increase in shield from the boosters would make the recharge time increase based on your power distributor’s ability to fill it back up.

Boosted shield recharge times

As you can see, if this is correct, the Cobra with 4A Shields and a 3A Power Distributor should recharge in 97 seconds. With a 0A Shield Booster, the shields are raised to 150.6MJ so will then take 116 seconds to recharge on the same ship (19% longer).

My Fer-De-Lance with 5A Shield Generator, 6A Power Distributor and four 0B Shield Boosters will therefore take four minutes and three seconds to restore shields!

My next quiz question is are shield cells based on a percentage or a fixed number of MJ? If the latter is true, then the more Boosters you use, the less effective even the best Shield Cells will become.
