Small Fleet Doctrine

Fleet Composition

The core problem with balanced fleet doctrine is that it convinces people that they need to build and use units that are unnecessary in a fleet. This gives your opponents an opportunity to destroy your fleet more efficiently. Balance is important. However, building units merely to create balance means you will spend too much to build a fleet. Your combat will suffer as you will not earn as much as you spend—they Pyrric victory. In this Section, we discuss each unit and their role in an efficient fleet. This precedes a short set of points to remember.

General Unit Advice

This sub-section provides general comments on the fleet units in Astro Empires.

There are four ship classes this guide recognizes:

• Support (Meat) Ships: (Fighers to Frigates).
• Escort Ships: These are large, units (Cruiser, Heavy Cruisers and Battleships).
• Capital Ships: These are massive units (Dreadnought and larger).
• Utility Ships: These are units you should never put into combat.

Generally speaking, your support fleet should be mostly Fighters with some Destroyers. Escort ships should comprise a balance of Cruisers and Heavy Cruisers. In the Small Fleet approach, capital ships are generally not built because of their inefficiency.

Support Ships

Generally speaking, there are three support (meat) units you want in battle: Fighters, Heavy Bombers and Destroyers. Fighters are the best in killing unshielded units. Heavy Bombers are effective in killing Escorts when there is no enemy Fighter support. Destroyers are also highly effective against Escorts; again when there is no enemy Fighter support. Corvettes are useful in raider, emergency resupply roles.

• Fighters: Anti-support
• H.Bombers (Bombers): Anti-escort
• Destroyers: Anti-escort
• Corvettes: Fast Raiders

We now look at the support units in greater detail.

Fighters (FT)

Build this unit. These are the staple of all fleets in AE—defense, offense, everything. Fighters are the single most efficient ship in Astro Empires. The damage they absorb per credit is unparalleled. That makes Fighters your primary unit for use as cannon fodder. It is literal to say that you can never have too many Fighters. A fleet that runs out of Fighters will take far higher losses, and can be defeated in detail for obscene exchange rates by anyone who manages to catch them. Build thousands for base defense, and then keep building them for use with offensive fleets. You go through Fighters at an obscene rate because Fighters are basically designed to die. Application of Fighter waves in combat can significantly improve your exchange rate.

Bombers (BO)

Consider this unit. Bombers have the same armor as Fighters with twice the firepower and twice the cost. This makes them slightly less efficient. While less efficient, they can still be slightly efficient meat. Their ability to harm Cruisers makes them especially handy in the defense until you have Heavy Bombers. Use them in an anti-Cruiser role. Their relative efficiency over Heavy Bombers makes them more useful than their counterpart in a defensive role.

Heavy Bombers (HB)

Consider this unit. Heavy Bombers pack enough punch to take out main fleet units—Cruisers and Heavy Cruisers—but they are vulnerable and expensive, as well. Heavy Bombers are best used in waves after you have used Fighter waves to destroy the enemy's unshielded units. Heavy Bombers are inefficient against unshielded units, and therefore should not be used in main fleet engagements. Enemy Fighters will cut them to ribbons. Therefore, they are best used in an offensive role.

HBs are also the best units for breaking occupations, if you have a proper amount of Command Centers.

Ion Bombers (IB)

Avoid this unit. Ion Bombers have double the price of Heavy Bombers, with the same power and armor. All they gain is one point of shielding, which does practically nothing for their survivability. Their weapons are Ion-based, so 50% penetrates shielding. They are so expensive that they are not even efficient in waves. If you send a wave of Ion Bombers against escort ships of equal value—be they Cruisers, HCs, or BBs---it is impossible for the Ion Bombers to come out ahead in the exchange. The first ship class they can attack efficiently is Dreadnoughts, though only barely. Escort ships are vastly more efficient in attacking capital ships than ion bombers. Avoid these units.

Corvettes

Consider this unit. The Corvette utility lies in its speed. They are not very useful in a battle fleet because they are too expensive compared to other support units. They are as efficient as Bombers, but their unique ability makes them better suited elsewhere. They are inefficient against all support, escort and capital ships.

Corvettes are good in a raider role. Build 500 or more and camp them at a Jump Gate for Recycler hunting and emergency resupply. They can also be used to hunt naked Frigates, if so inclined. They do not need hangars to travel between astros. Therefore, emergency resupply might help a fleet with insufficient Fighter support.

Destroyers (DDs, tin cans)

Build this unit. Because Cruisers and Destroyers share the Plasma weapons system, Destroyers are useful. They are very efficient in destroying naked Cruisers and Heavy Cruisers. They are inefficient against Battleships and Capital ships. They are also very inefficient against Fighter waves. So, when your opponent has a large Cruiser/Heavy Cruiser fleet, Destroyers are your counter-balance.

One tactic is to keep a lot of Destroyers at a Jump Gate to rush Cruisers or strengthen base reinforcements. They are especially useful with Command Centers, playing havoc with the enemy ratios. Their speed makes them handy at Recycler hunting. Do not leave Destroyers in hostile territory when you have to be offline.

Frigates (FR)

Avoid this unit. These ships are handy for one thing: telling whether or not a player is unsophisticated. They are inefficient against all units have have only one trival redeeming quality: hangar space. They are fast and can carry a few fighters. They may also be useful escorting otherwise naked Recyclers because they are offensive and can carry fighters. However, you are better served building any other unit.

Frigates are terrible unites. Never, ever build Frigages.

Escort Ships

Escort ships are shielded units that are generally capable of warp travel. They retain some vulnerability to support ships but primarily serve in an anti-capital, anti-escort role. This is a small class of ships, but your fleet should comprise a considerable percentage of it.

• Cruiser: Anti-Escort
• Heavy Cruiser: Anti-Fighter, Anti-Capital (Titans and smaller)
• Battleship: Anti-Fighter, Anti-Capital (Titans and larger)

We now look at the escort units in greater detail.

Ion Frigates (IF)

Avoid this unit. As with Frigates, these are terrible units. They have one possible use. They can be used to hunt down lone capital ships. With the improved hanger capacity, one might consider a Ion Bomber/Ion Frigate hunter group. However, two Ion Bombers are more effective than one Ion Frigate, if you can risk using a Carrier or Fleet Carrier. Follow the advice as for the normal Frigate. It is called an “escort” ship only because it is shielded.

Cruisers (CR)

Build this unit. In Small Fleet Doctrine, Cruisers serve a critical role. You will want to build these by the hundreds. They are the efficient killer of escort units (Heavy Cruisers and Battleships). They are less efficient against Fighters than Heavy Cruisers, and should never be used to “naked rush” Fighters. They are inefficient against capital ships. Cruisers protect your support fleet from Heavy Cruisers and Battleships. They are vulnerable against Heavy Bombers and Destroyers.

Cruisers are allegedly the most efficient way to take out Planetary Rings (P-Rings), but it takes a hundreds of them. Make sure you have enough. Cruisers should be the backbone of your main battle fleets.

Heavy Cruisers (HC)

Build this unit. Heavy Cruisers are the bruiser of Astro Empires. Their shields are high enough to let them nakedly rush Fighters. They are inefficient against Heavy Bombers and Destroyers, and should have Fighter support in that attack. Heavy Cruisers are efficient killers of capital ships (Dreadnoughts and Titans). When your rivals start building capital ships, then start building this unit. They are less efficient in main fleets where there are no capital ships. Titans are massively inefficient against Heavy Cruisers. However, Leviathans are massively efficient against HCs. Death Stars are immune to Heavy Cruisers, but Death Stars are floating credit banks.Therefore, you do not need build these until you start seeing Dreadnoughts and Titans.

Battleships (BS)

Consider this unit. As ships get larger, they tend to become less efficient. They are significantly efficient against support units, able to destroy more than 12 times their value in Fighters and Heavy Bombers. They are inefficient against escort ships. Therefore, use Battleships to destroy support fleet in coordination with Cruisers and Heavy Cruisers.

In an anti-capital role, Battleships are generally grossly inefficient. They are balanced against Dreadnoughts. They are less efficient than Heavy Cruisers against Titans. They are the most efficient escort ship for killing Leviathans (but still require nearly three times the fleet). They are very efficient against Death Stars. Therefore, do not build Battleships for in an anti-capital role until you are faced with Leviathans and Death Stars.

Capital Ships

Captial Ships are the massive units that provide bragging rights to senior players. To younger players, they provide shock-and-awe. However, the bigger units get, the less efficient they are. The big stuff is best used against things that cannot hurt it. Small Fleet Doctrine discourages building any of these units until you have a firm grasp on their use and can effectively destroy your rival's capital units and defend your own.

Dreadnoughts (DN)

The strength of these units is their shields. They are great for attacking bases that have defenses weaker than Disruptor Turrets, provided the defense fleet is not large enough to have a chance at killing the Dreadnought.

Dreadnoughts are a fair addition to combat fleets when attacking things that cannot kill them and are willing to tolerate the long travel times. If a Dreadnought would be destroyed in the attack, it is preferable to leave it out. Otherwise, a safe Dreadnought will help soak damage that would otherwise destroy other units. Therefore, think of Dreadnoughts as inefficient, floating shields.

Titans (TI)

Titans are massively inefficient against Heavy Cruisers and Battleships. They are able to destroy Cruisers effectively because of the Titan's shielding. However, the terrible speed and terrible efficiency of the Titan mean you should leave them off your list. Twenty Battleships will kill a naked Titan, as will 130 HCs; assuming technology is the same. The HCs should yield about a 2:1 kill ratio, while the BBs will yield around 1.5:1. Titans are great to send out solo to smash bases with defenses less than rings.

If your opponent has disruptors as his highest defense, then Titans will kill the base pretty easily, unless he has high disruptor tech or a Dread with high CCs in addition to a fighter screen.

Leviathan

Levianthans are allegedly useful for taking bases with Disruptor Turrets. However, they are still massively inefficient against a determined escort force. One should accept that taking bases is a secondary objective. The primary objective is destroying your opponent's fleet and collecting the debris.

Utility Ships

Utility Ships are those ships which you need, but should never be used in combat. This guide does not discuss Outpost Ships as they have one obvious, limited role.

Always retreat utility ships before attacking. They are not meant for fleet operations.

Recyclers (RC)

These are not combat units. However, they are critical to successful fleet operations. Resource denial is key to waging war in Astro Empires. You should probably have at least 1000 for effective hit-and-run tactics.

Carriers (CA)

Support ships (mostly Fightes) are useless outside the base that built them because they need transportation. Carriers are the smallest unit that can carry Fighters by the boat load. They have less survivability than Fleet Carriers, but they are also faster. Keep a group at your jumpgates for rapid reinforcement.

Fleet Carriers (FC)

Fleet Carriers sacrifice speed for survivability and portage. They have strong enough shields to shield-rape small units. If you have a calculator and you are very careful, it's possible to include FCs in attacks to improve ratios. This is dangerous, though. Avoid this unless you are experienced. You should have lots of FCs to move all your Fighters around.

Major Points to Remember

Here are the most important parts for review:

• Fighters and Cruisers should be the bulk of your fleet—70 percent your total fleet size.
• Keep enough HCs around to deal with the big stuff, with more than that if you want to use them in main fleets.
• Do not build Frigates, Ion Frigates, or Ion Bombers. You are wasting your production time and money.
• Bigger is not always better. The bigger you get, the less efficient you get. Do not build too much of the big stuff.
