Stealth Bombers

Stealth bombers are one of the earliest T2 ships that new pilots and pilots using Alpha accounts can fly. These ships travel through systems undetected, approach under cloak, and deliver high-damage torpedoes and bombs on unsuspecting targets. Flying in a fleet, stealth bombers provide surveillance and dps. Flying solo, stealth bombers provide surveillance, but one downside to flying alone is the high chance of being destroyed at gatecamps. Stealth bombers are one of the most powerful tier II (T2) frigates in New Eden. This page covers general information about stealth bombers.

Hound	Manticore	Nemesis	Purifier
The Minmatar Hound	The Caldari Manticore	The Gallente Nemesis	The Amarr Purifier

Which bomber?

Pilot preference. Pilots can choose how to fly their bomber and configure modules accordingly.
Each race has one stealth bomber with its own combination of module slots.
-recommended bomb platforms: Amarr Purifier, Minmatar Hound
The Purifier and the Hound have a 3L-3M-5H slot layout.
-recommended torpedo platforms: Caldari Manticore, Gallente Nemesis
The Manticore and the Nemesis have a 2L-4M-5H slot layout.

Other than slot layout and preferred damage type, there are few major differences between the bombers.
The Nemesis is bonused for thermal damage, which is the least often resisted damage type in pvp.
The Purifier has a largest cargo bay, which allows storage for 3 bombs.
The Manticore has the highest CPU, which allows easier fitting.
The Hound is the most agile, which allows faster align time to escape dangerous situations.

Hound

The Minmatar Hound

The Hound is the Minmatar Stealth Bomber. It gets a bonus to explosive damage and uses Nova torpedos. It features a 3L-3M-5H slot layout, composing of three low slots, three mid slots, and five high slots. The Hound's 3L (three low slots) could fit Ballistic Control Systems (BCS) modules, but due to their high-CPU requirement, fitting three BCS modules may be a challenge. The Hound also has the fastest align time (faster warp to/faster escape from) and the highest scan resolution (faster lock time) out of all of the bombers.
With the exception of the torpedo type, the fit is the same as the Purifier, though pilots may find it a touch easier to squeeze everything on due to a slight difference in CPU.

Manticore

The Caldari Manticore

The Manticore is the Caldari Stealth Bomber. It gets a bonus to kinetic damage and uses Scourge torpedoes. It features a 2L-4M-5H slot layout, composing of two low slots, four mid slots, and five high slots. The Manticore's 4M (four medium slots) have to option to fit one more utility/EWar/etc module (Sensor Dampener, Target Painter, Capacitor Booster, etc.)
It has the highest CPU, making module fitting ideal.

Nemesis

The Gallente Nemesis

The Nemesis is the Gallente Stealth Bomber. The Nemesis gets a bonus to thermal damage and uses Inferno torpedoes. It features a 2L-4M-5H slot layout, composing of two low slots, four mid slots, and five high slots. The Nemesis's 4M (four medium slots) have to option to fit one more utility/EWar/etc module (Sensor Dampener, Target Painter, Capacitor Booster, etc.)
It has less CPU, making Tech 2 module fitting a challenge.

Purifier

The Amarr Purifier

The Purifier is the Amarr Stealth Bomber. It gets a bonus to EM damage and uses Mjolnir torpedoes. It features a 3L-3M-5H slot layout, composing of three low slots, three mid slots, and five high slots. The Purifier's 3L (three low slots) could fit Ballistic Control Systems (BCS) modules, but due to their high-CPU requirement, fitting three BCS modules may be a challenge. It has the least CPU, which makes module fitting tight and not quite as varied as the other races.

Fitting

All stealth bombers get a 15% bonus to racial torpedo damage:
Amarr = +15% EM damage
Caldari = +15% Kinetic damage
Gallente = +15% Thermal damage
Minmatar = +15% Explosive damage
as well as a 5% bonus to racial bomb damage per level of Covert-Ops trained. In addition, bombers get a flat 100% bonus to torpedo velocity and a 50% bonus to explosion velocity and torpedo flight time. Lastly, they receive a flat role bonus of a -99.65% reduction in Torpedo Launcher powergrid needs, -50% reduction in Cloak CPU Use, and -100% targeting delay after decloaking. These last three skills are to ensure the ship can equip battleship size missile launchers, and that the covert-ops cloak is used exclusively on covert-ops ships.

In fitting a bomber it is ideal to maximize potential damage. This is done largely with the use of target painters, and ballistic control systems. These greatly increase the DPS torpedoes do to non-battleship size targets. Newer players will have trouble fitting three launchers as well as a bomb launcher without perfect fitting skills. The purifier, in particular, is difficult to fit.

A standard general fitting is as follows. Work your way down the list to gauge how much CPU you have left to fit the next module down the list.

High Slots:
1 Covert Ops Cloaking Device II
3 Prototype 'Arbalest' Torpedo Launcher or Torpedo Launcher II
[1 Bomb Launcher] (CPU dependent) [1 Probe Launcher] (CPU dependent)

Mid Slots:
1 Propulsion Module (afterburner/microwarp drive)
1 Target Painter (100km)
1 Remote Sensor Dampener
1 Optional module (warp disruptor 20km, warp scrambler 10km) *

Low Slots:
1 Ballistic Control System (increased rate of fire) or
1 Optional module (a second Ballistic Control System, auxiliary power core, co-processor) *

=Adding extra modules depends on your ship's CPU limit
- =The Bomb Launcher is largely very difficult to fit in addition to the three 'Arbalest' launchers due to CPU limit.

Bombers can alter the standard fit to include 1 bomb launcher and offline 1 or 2 torpedo launchers, or fit for 3 torpedo launchers only.

The choice of what meta level module to fit into the mid and low slots is largely capsuleer choice, however it is recommended that pilots fit the highest (up to meta 5/Tech II) module possilbe. If CPU usage is a problem with the Arbalest launchers, the meta 1 variants (Malkuth) offer less performance but less CPU usage. Alternatively, if the DPS difference is smaller, altering the rigs used on the bomber may allow for better fits.

The sensor dampener is used to increase the bomber's lifespan. Dampeners are used to reduce enemy ships targeting range and scan resolution. It is recommended that all ships carry both scripts in their hull so switching can be done on the fly. However, in multiple bomber gangs, it is usually advised to run the targeting range script.

All bombers should be carrying Faction torpedoes due to smaller explosion radius.
Dread Guristas variant torpedoes deal the biggest damage/are the most expensive.
Caldari variant torpedoes deal big damage/standard ammo for stealth bombers.

Alternative low slots

The remaining low slot should be filled with a module of the player's choice, however it should still play to the strengths of the ship. This means that the final low should be a nano-fiber internal structure, or perhaps an overdrive injector system. Alternatively to agility mods, a Damage Control or Adaptive Nano Plating if possible to fit can work as well.

Modules that are not recommended

Often it is suggested that fittings equip sensor boosters, or tracking disruptors. While these can be beneficial, they are also very situational. Tracking disruptors are flat out useless against enemy missile ships (for now), thus limiting the types of engagements one can be useful in. Sensor boosters, while good for locking quickly, is somewhat counter-productive to the whole idea behind bombers. Targeting anything that can warp off quickly, or has a small signature radius means torpedo damage is going to be negligible. Meanwhile, bombs require no lock to fire, and are thus preferred for engaging smaller targets, but bomber cargo bay capacity limits the number of bombs onboard to less than 3, including the bombs loaded inside the bomb launcher, but bomb damage is proportional to target signature radius (a 5000 damage bomb will only cause 500 damage to a target signature below 100m), and bombs can only be launched in 0.0 security space, -0.1 and below space, and wormhole space. Bombs launchers are automatically offline and unusable in Empire space (0.1 - 10.0 security space).

Additionally, it is sometimes suggested bombers fit shield extenders to increase their survivability. This is not recommended as shield modules generally increase the signature radius, and thus make the bomber easier to lock and easier to hit. This runs counter to the idea and tactics employed with the bomber. The argument for survivability also is largely irrelevant. The bomber is a glass cannon, trying to increase survivability is trying to mitigate the ship's weaknesses instead of playing to its strengths. Bombers are ideally fit for speed and as much damage-per-second as possible, against target signatures greater than 400m. In this same fashion, Inertia Stabilizers also increase the signature radius and should not be used. In contrast, should a bomber enter a system and uncloak inside a surprise gate camp warp bubble, the bomber has a higher chance of survival if it is equipped with more shield capacity, re-approaches the gate, overloads the afterburner and spams the jump button to escape through the gate.

Rigs

The choice of rigs used on the bomber is largely player preference. The most often used, the Warhead Calefaction Catalyst boosts torpedo damage, however other modules increase missile range (useful for staying outside targeting range {thanks to your sensor damps}) and velocity, or firing rate and thus DPS. Alternatively, there are rigs to decrease explosion radius (increased damage versus smaller sized ships) and explosion velocity (increased damage to faster moving ships). Most of the different missile launcher rigs are useful in someway on the stealth bomber. It largely depends on individual flying preferences and styles. The downside to these rigs is that they also increase the CPU usage of each launcher, making fitting even more difficult.

Astronautic rigs are also widely used, these are useful in increasing ship agility and speed. These are useful in situations in which the bomber needs to align quickly and warp off the grid. These situations are frequent with bombers and thus having a short align time is a must. The downside of these rigs is that they reduce armor amount, and thus make the bomber that much more fragile. Suggested astronautic rigs are Low Friction Nozzle Joints and Poly-Carbon Engine Housing.

Since the introduction of the Processor Overclocking Unit rigs with the Inferno expansion, these are useful on stealth bombers as well. Processor Overclocking Unit rigs increase the CPU output of your ship at the cost of a slower regeneration rate of the shields. Stealth bomber fits still remain tight but with these rigs, it is possible to mount tech 2 Torpedo launchers alongside the other standard modules including the Bomb Launcher.

The Bomber uses size small rigs.

The different roles of stealth bombers

Black Ops gang

Bombers can be very effective in gangs of all cloaky ships. Usually, a recon will find and tackle a good target and then call in the rest of the gang, either from the neighboring system, wormhole or by lighting a cyno for a black ops battleship's covert jump portal. In this role, bombers tend to be optimised for torpedoes rather than bombing.

Bombing wing

A large fleet can be accompanied by a force of bombers. The bomber force acts mostly independently of the main fleet, often with their own FC and as a separate in-game fleet. The bomber wing will try to get bombing runs in on the enemy fleet to destroy, soften up or simply distract them as support for the main fleet. Bombers in this role will be bomb fit.

Bombing squadron

In general usage, a Bombing Squadron is composed of 7 bombers. It is required that all bombers in the squadron have the same type of bomb. Ideally, the squadron is homogenous as far as the type of bomber hull.

Fleet Damage Dealer

Operating in the fleet, independently A bomber attached to a fleet that is not part of a bombing wing (there may be too few bombers or the fleet is fighting in high or low sec where bombs are not available) will normally use torpedoes. In this role, a bomber acts like a cloaked EWAR ship, warping in at range, aligning, uncloaking, fighting aligned at maximum range and warping out when targeted. If left alone, a bomber's torpedoes will do impressive damage to ships that have or generate a large ship signature (battlecruisers and battleships). However, if a bomber is frequently targeted and continously warps off, applied damage to target is lowered considerably. Bombers can be used in frigate gangs to bring a "big punch" for use against large targets. Eve University roams will sometimes find large signature targets, and in these situations, torpedoes provide significant damage. If small signature targets are locked and scrammed, torpedoes provide a fraction of total damage, but it is still damage on target, so don't let target size stop you from using torpedoes. There may be chances that the small target has an activated microwarp drive on, while being webified, increasing that target's signature bloom to 500%, which will greatly absorb 50-75% torpedo damage. Remember, bombers may have very low hit points, and can be destroyed in one or two hits, but if your bomber is in a safe and aligned position to launch torpedoes on any target, small or large, by Eden, send your torpedoes flying, give that target a hug.
Do not decloak until the following requirements are met:

Be in position at optimal torpedo launch range.
Align out.
Be ready to fire at a target with signature radius large enough to take significant damage from torpedoes.
There is nothing around that can tackle your ship (tackle ships, interceptors, Lachesis).

Fleet Scout

A bomber attached to a fleet may perform the role of scout and report target movement and intel to the FC.
-Scout ahead or behind the main body
-Evade gate camps and enemy fleets
-Remain cloaked at safe distance from stargates and deadspace sites
-Position behind target ships undetected to provide a tactical fleet warp-in

Fitting exceptions

Probe Launcher
- A bomber may be requested to fit an expanded probe launcher to find further targets in the system. The extreme CPU requirements of this module require it to be kept offline or to use a modified fit that will seriously reduce the bomber's effectiveness at its main role. As such, if the fleet needs a prober a covert ops ship is very much preferred.
Warp Disruptor
- If recon ships are not in fleet during Black ops operations then a Manticore or Nemesis stealth bomber may also need to fit a warp disruptor (Point) in the extra mid slot, and act as a tackle. This should only be used as a last resort because a bomber has low hp and usually cannot hold a tackled target for long.

Tips

The five "R's"

Bombing runs are the ultimate purpose of Stealth Bombers. To throw bombs at some unsuspecting group of ships defines the concept of gank. However, if in the throwing of bombs you find yourself on the wrong side of the killmail you may be forgetting the Five "R's".

RUN AWAY: As soon as your bomb is released, warp away. With few exceptions, the Stealth Bomber never remains on grid post bomb release. Uncloak - Bombs Away! - RUN AWAY!"
REMOVE YOURSELF: After running away, you will likely be heading in warp to a pre-planned escape point. Upon landing at that escape point, REMOVE YOURSELF from the place you just landed. Other members of your squadron may be landing there in short order and SB's in close proximity post-attack is a mistake. Your aim is to be at least 2,500 meters away from your landing point so decloaking is less likely to happen.
RELOAD: As soon as practical after launching your bomb RELOAD your bomb launcher. Many escape points are far enough away that you ought to be able to complete a 10 second reload prior to landing. A fully loaded stealth bomber has more utility than a half empty launcher. Plus, it frees up space in cargo for more bombs or even loot if your run was wildly successful.
RECLOAK: An SB that is not cloaked is a glass pigeon waiting to get popped. RECLOAK as soon as you have reloaded.
RESET: After reaching your escape point the bomber leader may have you RESET at an observation point. Being ready to go on command or even anticipating the reset may give your squadron the opportunity to restrike a target... Be ready, immediately.

Pre-fleet

Bookmarks, bookmarks, bookmarks, BOOKMARKS! Spend some time in a fast frigate (fitted with a cloaking device and Overdrive injectors) before the operation creating bookmarks around the system gates of interest. Create, at the least, two perches, and eight tacticals (bookmarks at ~200km, ~800km at each cardinal direction, bookmarks at ~200km, ~800km above and below) at each gate.
More BOOKMARKS! Revisit the systems and expand your bookmark database. A near-perfect 78-bookmark tactical grid above and below every gate in every system your fleet roams through qualifies you for the "Bomber Grid Master" and "Hero of the Fleet" decoration medals. See your corporation about decorations and accomplishments.
Tactical bookmarks, that is, bookmarks on a gate or station placed 250-350km away from the gate are your life blood and savior in bombers. They allow you to warp into a gate at range, to check the gate for potential targets, without the worry of being decloaked by enemy ships. Additionally, bookmarks provide a great close-to-the-fight bounce spot if you need to warp out of an engagement. Warping to a bookmark 200km away from the fight is a much faster way to break a lock, cloak back up, then warping to a celestial. Additionally, tactical bookmarks around warpgates and stations will save your ship countless times in null security space where bubbles abound on gates and stations.
Know the numbers of your ship.

optimal range of your launchers
optimal warp-in range to target vs. gate/deadspace site situation
launch cycle time: 10-12 seconds for the first volley of torpedoes to hit the target. It is not uncommon to have up to 2 volleys in space before the first torpedo hits the target.

Basic fleet tactics

*Remain cloaked at all times. Do not break cloak until ready to fire.

Make sure your fleet commander knows he/she has a bomber in fleet. Do this before the fleet undocks.

"This is Joe Spaceman checking in. I have a Purifier with Dread Gurista Mjolnir torpedoes and 4 Focus Void Bombs. Where do you want me?" Check that the FC is happy to have bombers along, and find out if they want to use you in a specific way. If the FC cannot use your bomber, you can still travel with the fleet, but travel out-of-fleet and remain in Mumble comms. The worst thing a bomber can do to the fleet is 1)accidentally launch a bomb into the fleet in non-Empire space, 2)lose a bomber in a situation that was avoidable and cause negative isk efficiency to the fleet, the fleet commander's after-action report, and the university standing.

Travel ahead or behind the fleet. Do your best to travel just behind or in front of the fleet (sort of a -1 or -0.5). Showing up after the battle is in full swing for a surgical strike is where bombers really shine. Your goal isn't to be the first thing they see, but the last. This tactic gives the target no chance of finding a bomber in an attacking fleet, the target's overview is already filled with flashing yellow targets and has already locked and targeted its maximum number of targets. A bomber uncloaking after the target has locked onto five fleetmates will stand a greater chance of launching torpedoes and surviving than a bomber uncloaking and landing on grid with the fleet.
Land on grid at range and move to the side. After landing at the battle grid, double click in space in a direction perpendicular to the direction you approached from before realigning. This will keep fleetmates who show up a few moments after you from decloaking you if they arrive on grid on the same line.
Move into optimal firing range and ALWAYS ALIGN OUT before decloaking. Be on the field as close to the beginning of the battle as possible, in comfortable torpedo optimal range (around 40-50km) and aligned to a celestial (for advanced pilots, align to a bookmark ~200km from the fight, if at a gate). Wait for the battle to start. Waiting gives the target time to lock its maximum number of attacking ships.
Pre-load modules. While cloaked, some of the bombers modules cannot be pre-activated. Be ready to mash all the hotkeys at once after decloaking. Every second of lag counts against the bomber.
Decloak, lock target, launch torpedoes. Decloak after the battle starts and the desired targets are otherwise over-occupied. Attack whatever ship your FC calls primary. Only decloak if you are ALIGNED OUT, ready to lock, and attack immediately. Once you get a lock, activate all of your torpedo modules and wait for impact.
Launch two salvos, wait for impact, cloak. You cannot re-cloak immediately. Generally firing around 2 salvos while getting ready to either re-cloak or warp out is ideal. However, if there is an abundance of blue force ewar on the field, you may consider staying to unleash the pain. When your second salvo launches, wait for impact. If your ship cloaks during any torpedo flight time, those torpedoes will not impact the target. Re-cloak and wait for your launcher cycle to finish. You can cloak while your modules are active; they will automatically shut off.
Warp to the close-to-the-fight bookmark or celestial if you are targeted and taking damage.
Decloak and repeat. Your torpedoes will NOT hit if you 1)re-cloak within 3 seconds of them hitting the target, 2)warp away within before the torpedoes hit the target.

Ships to watch out for

Interceptors/Fast Tackle: Atron, Condor. They can close the 50km gap between you and the battle in a matter of seconds. They will do this, and they will kill you. Keep your overview sorted by range, and when you see someone moving up the list quickly, it's time to bounce, cloak, and then return to the fray from a different angle.
Sniper ships: Tornado, Naga, Oracle, Apocalypse, or Zealot, or ships fitted for ranged attack. They only have to hit you once, and your sensor dampener will not be effective enough against them to keep you safe from their attack.
Drones: A target's drones will continue to attack you after they have been jammed and their locks on you will prevent you from cloaking. Even after the target has been destroyed its drones can keep you locked and prevent you from cloaking. The point here is to not get locked. At all.
Heavy Assault Cruiser (HAC) / Factional Cruiser: Vagabond, Dramiels, Cynabals, are frigate killers. These ships have speed, distance, Drones, and a punch. If these are on the field then keep cloaked until they are destroyed, or watch them like a hawk for signs they are coming for you.

Rookie mistakes

New Stealth Bomber pilots will probably do one or two of these mistakes at least once:

Warp to 0 on a battle
Warp to 0 at a warp gate
Warp to 0 at a Gallente Novice Outpost with a flashing yellow Stilleto and Griffin waiting outside the acceleration gate
Uncloak friendly bombers at a wormhole
Enter a -security system without a scout and get podded in an inescapable warp bubble
Linger on a gate and destroyed by smartbombs
Forget to align before decloaking
Fail to move off the landing area, uncloaking fleetmates as they land
Fail to warp off within three seconds of being yellow-boxed by the enemy
Get locked by an enemy and tell themselves "I'm good for another salvo."

Targets

Good targets for bombers: Battlecruiser, battleships. You will be most effective against larger targets like battlecruisers and battleships. At no point should a bomber ever consider engaging any cruiser or frigate by itself. Cynabals and Dramiels are bomber eating machines.
Medium targets for bombers: cruisers, a ship with active microwarpdrive. Target painters will help against cruiser hulls, but what you really want is for them to activate their MWD.
Bad targets for bombers: frigates. Frigate hulls can shrug off a lot of torpedoes. You can whore on the mail if you really must, but if you haven't yet uncloaked and there's some intel value in not revealing your presence to anything in d-scan range, you may want to consider holding off.

The torpedo explosion radius will be too large to apply full damage to the small signature radius of a frigate, unless:

the frigate is locked (no warp, no velocity) and still in space
the frigate is affected by ten or more target painters
your fleetmates have some kind of fleet booster that will shrink your torpedo explosion radius down to 40m to match the target frigate's signature radius (no way possible), but even under the above conditions, the target frigate will absorb only a fraction of the torpedo damage. Save your expensive torpedoes, practice launching cheaper torpedoes.

If you have an abundance of torpedoes and don't care about wasting them, send any and all of your targets some love.

Bombing techniques

Bombs don't work in Empire Space
The other thing that sets the bomber hull apart, besides the ability to fit torpedoes onto a frigate hull, is where it actually gets it name from - the ability to fit the Bomb Launcher I/II. From this module you fire the six flavors of bombs that exist. But what is a bomb actually?

Bombs cannot be launched in high security space
Bombs cannot be launched in low security space
Bombs can only be launched in 0.0 security space, nullspace, and wormspace

The bomb

Bombs are in essence a missile that does Area of Effect damage of a certain type. It will shoot out from the front of your ship at 3km/s for 10 seconds and then blow up. However, unlike a missile, it doesn't require that you lock a target. It's essentially a 'dumbfire' rocket. Where your ship's nose is pointed at the time you cycle the bomb launcher module, is the direction it will go. This makes the bomb a weapon that takes a fair bit of experience and skill to use effectively. And when you factor in that you have six other bombers also shooting off a bomb, the complexity increases and the skill of the FC becomes a critical factor. Then imagine that you have multiple bomber wings making a run on the same target... it sounds impossible to coordinate and pull off, but it can be done.

Bombs can also be separated into two categories.

Damage Bombs: Straight forward big explosions of either EM, Explosive, Thermal or Kinetic damage.

Utility Bombs: They require higher levels of skill with Bomb Deployment, but are useful in niche situations. The Void Bomb will neutralize a certain amount of capacitor energy from any ship within its area of effect. The Lockbreaker Bomb is an ewar bomb in essence. It will cause any target locks that a ship is maintaining to fail within its area of effect.

Team technique

This is where each bomber is coordinated by the FC. The FC will call for each bomber to approach/align to a target/target zone/bookmark. They will warp to the point where they begin their attack run, approach and call out ranges to target for the FC. The FC then has to judge the best time to order the release of bombs, whereupon the wing will warp immediately to the escape point. Onus with this technique is on how well the bombers act as a team, and actual piloting skill. It's versatile, flexible and the FC can call abort at any point until the bombs are flying. It's also ideal for bombing single/small gang targets. Its weakness is that fleet management and FC-ing becomes impractical as soon as you grow beyond two wings of bombers. It also allows human error in aiming the bomb into the equation.

Quarterback/Flyhalf technique

This technique uses a cloaked scout to sneak to within 30km of the enemy fleet/target and act as a target guide for the incoming bomber fleet. The FC then warps the bomber fleet to the cloaked scout a point where he can draw a straight line from the bomber fleet, through the scout, and straight into the enemy targets, release bombs such that the explosion radius is outside the cloaked scout's position.
The FC shall fleet warp the bombers to the scout at zero. In mid-warp, all bombers will keep a close eye on their target distance and ownship's speed (cursor over the warp/speed meter in the bottom center of the HUD). The moment the bomber's speed begins to decelerate, decloak, and spam the bomb launcher button, until it turns red. The effect of this is the bomber will exit warp, decelerate, and the instant your warp field collapses, launch a bomb from the bomb launcher. Bombers can immediately warp off to the escape point, or align to a random celestial (in the case of an ad hoc bomb attack) to escape, reload their bomb launchers and cloak up. The advantage of this is that it allows for minimum amount of time on a dangerous grid, the aiming has already been done for the whole bomber wing by the cloaked scout, and the mid-warp shuffle that the game does to arrange the ships, has the effect of nicely overlapping the AOE damage of each bomb.

The Flyhalf technique also allows for the coordination of multiple wings of bombers. When the bomber fleet gathers at the observation point, they are assigned ranges to warp at. (John warps at 0, Jill at 10, James at 20, Harmony at 30, Guile at 50, Titus at 70, Steven at 100). This will prevent a mass cascade decloak of the entire fleet if one person DCs/makes a mistake, or in the case of a spy/awoxer/sabotage pilot, only one bomber wing will die. The FC can then squad warp each bomber group at will at the enemy. Ensuring enough time between squad warps so that their bombs have enough time to detonate before the next wave of bombs goes off.
