Fitting a Tengu with HAMs

In a previous post, I detailed a few Tengu fits I have owned or flown.

Since the Retribution patch, it’s worth revisiting some of these fits to see if they hold up, or whether a heavy assault missile (HAM) fit would be better.

6-Launcher DPS Fit

The old fit output 658DPS @ 110km with heavy missiles (factoring in reload time); this has since been reduced to 624 DPS @ 70.7km.

An alternative would be this HAM fit:

[Tengu, pve slightly ganky HAM]

Caldari Navy Ballistic Control System
Caldari Navy Ballistic Control System
Ballistic Control System II
Ballistic Control System II

Republic Fleet 10MN Afterburner
Caldari Navy Kinetic Deflection Field
Gistii B-Type Small Shield Booster
Phased Weapon Navigation Array Generation Extron
Federation Navy Stasis Webifier
Gistii B-Type Small Shield Booster

Heavy Assault Missile Launcher II, Scourge Rage Heavy Assault Missile
Heavy Assault Missile Launcher II, Scourge Rage Heavy Assault Missile
Heavy Assault Missile Launcher II, Scourge Rage Heavy Assault Missile
Heavy Assault Missile Launcher II, Scourge Rage Heavy Assault Missile
Heavy Assault Missile Launcher II, Scourge Rage Heavy Assault Missile
Heavy Assault Missile Launcher II, Scourge Rage Heavy Assault Missile

Medium Rocket Fuel Cache Partition II
Medium Hydraulic Bay Thrusters II
Medium Warhead Rigor Catalyst I

Tengu Offensive – Accelerated Ejection Bay
Tengu Propulsion – Fuel Catalyst
Tengu Defensive – Amplification Node
Tengu Electronics – Dissolution Sequencer
Tengu Engineering – Augmented Capacitor Reservoir

which has a respectable 911DPS @ 36.3km. If range is still an issue for you, replacing the afterburner with a 10mn microwarp drive would bump your speed up to 1250m/s, requiring a medium ancillary current router rig. It will be barely cap stable, so it’s best to faction or deadspace it.

5 launcher tank fit

The old fit was 518DPS @ 110km with heavy missiles; now only 491dps @ 70.7km. That’s still pretty reasonable for long-ranged combat without a propulsion module, but there might be some benefits to using HAMs instead.

Domination Large Shield Booster

Heavy Assault Missile Launcher II, Scourge Rage Heavy Assault Missile
Heavy Assault Missile Launcher II, Scourge Rage Heavy Assault Missile
Heavy Assault Missile Launcher II, Scourge Rage Heavy Assault Missile
Heavy Assault Missile Launcher II, Scourge Rage Heavy Assault Missile
Heavy Assault Missile Launcher II, Scourge Rage Heavy Assault Missile

Medium Warhead Rigor Catalyst II
Medium Hydraulic Bay Thrusters II
Medium Warhead Flare Catalyst II

Tengu Defensive – Amplification Node
Tengu Electronics – CPU Efficiency Gate
Tengu Engineering – Capacitor Regeneration Matrix
Tengu Offensive – Accelerated Ejection Bay
Tengu Propulsion – Gravitational Capacitor

678DPS @ 30.3km is reasonable (452 @ 54.7km with javelin)

A propulsion module is required to ensure that you’re in range, cutting the tank by a fair margin (again, a 10mn MWD fits with an ACR but sacrifices cap stability unless it’s deadspace) It’s still way over 1000 permatanked Serpentis dps though, which should be fine for all your afk answering-the-doorbell needs.

I’m not sure whether this is an improvement. Sure, it deals a fair bit more damage, but 5-launcher Tengus aren’t really in it for the DPS; they’re used because it’s easy-mode. To that end, I think the 5-launcher fit is probably best with heavy missiles unless you’re willing to spend the effort getting into range. Having said that, the difference between Scourge Fury heavy missiles and Scourge Javelin assault missiles is fairly small, so that’s an option as well.

Welp

Turns out I’m terrible at paying attention to local.

Shadai  over at Sleepless in Space posted a series of Strategic Cruiser fits for combat salvaging during wormhole operations.

Turns out that the Tengu does exceptionally well in this role, too:

3x Salvager II

3x Small Tractor Beam I

1x Heavy Missile Launcher II

2x Large Shield Extender II

1x Magnetic Scattering Amplifier II

1x ECM – Phase Inverter II

1x ECM – White Noise Generator II

1x 10 MN MWD II

1x Damage Control II

1x Signal Distortion Amp II

1x Medium Anti-EM Screen Reinforcer I

1x Medium Anti-Explosive Screen Reinforcer I

1x Medium Salvage Tackle I

5x Hobgoblin II

5x Hornet EC-300

1x Defensive – Adaptive Shielding

1x Electronics – Emergent Locus Analyzer

1x Engineering – Augmented Capacitor Reservoir

1x Offensive – Rifling Launcher Pattern

1x Propulsion – Interdiction Nullifier

LOL-tastic damage, but can tractor in from up to 40km and jam fairly effectively (although without the long range you’d get from an Obfuscation Manifold). You could easily swap the missile launcher for a remote shield repairer for gang work, or refit for extra jam range instead of extra tractor range if you need it.

Fitting a ship in Eve Online is a lot like playing with LEGO; things sometimes don’t fit, you get halfway through an edifice and realise it looks terrible, and scrounging for parts is part of the fun. However, when you build a spaceship out of LEGO, you can only blow up other people in your imagination. Score one for Eve.

However, there’s a few things to check before you undock for the first time…

Skills

To fly a Tengu, you need skills to be trained. Assuming you have the prerequisite support skills to fly a Caldari ship without embarrassing yourself, the only skills that are up for debate are the subsystem skills. I suggest that the minimum skill level required to fly a Tengu effectively is:

• Caldari Offensive Subsystems V
• Caldari Defensive Subsystems V
• Caldari Engineering Subsystems IV
• Caldari Electronics Subsystems IV
• Caldari Propulsion Subsystems IV

Offensive and defensive subsystems should be maxed because the most common mix of subsystems provide massive benefits for each level trained, so why not max them out.

You can limp along with engineering, propulsion and electronics subsystems at IV for a fair while, although you’ll eventually find that engineering subsystems at V is worth it for increasing your cap stability. Electronics subsystems V is mandatory if you’re probing or jamming but you can get away with less if you’re just shooting things. Similarly for propulsion systems – if your tank isn’t breaking on IV, then training to V can be left until later.

Granted, most people eventually skill all subsystems to V, so enough said about subsystem skills.

Rigs

You can swap the subsystems in and out of a Tengu, but you can’t detach the jury rigs without destroying them, so it’s important to choose wisely.

Most Tengu fits use the Accelerated Ejection Bay, which lacks a drone bay. This makes killing frigates an important consideration, since they’re also the ship classes most likely to web and warp scramble your ship, with tragic results. To combat this, a Medium Warhead Rigor Catalyst or Flare Catalyst will mitigate the damage reduction frigates experience against heavy missiles. This is even more important when using Scourge Fury heavy missiles, which require assistance to even hit cruisers for full damage. Alternatively, a Bay Loading Accelerator will just pump more missiles at the target, killing faster via brute force, but chews up a lot of calibration points.

If you’re more concerned by tanking ability than DPS, then you’ll probably fit Capacitor Control Circuits instead – especially since your shield booster will be substantially larger than on a DPS fit.

Modules

With a ship as expensive as a strategic cruiser, it makes sense to fit faction modules where CPU or capacitor is tight. Of particular note are deadspace shield boosters, which are incredibly cap-efficient for their size and are often (ab)used in Tengu fits.

Now, onto some fits. I don’t claim these are optimal, but they’re representative of the sorts of popular fits that Tengus are configured for.

6-Launcher DPS Fit

Medium Warhead Rigor Catalyst II
Medium Capacitor Control Circuit I
Medium Warhead Rigor Catalyst II

Tank: 700 DPS Guristas
Gank: 700 DPS with my skills
Cap stable (just)

This fit is for anomalies, level 4 missions and general ratting, where you don’t need to tank excessively. For example, this fit can run a Serpentis Sanctum without needing the second shield booster active, but needs the second shield booster in Angel Sanctums.

Six launchers provide maximum offense but capacitor may be an issue. Note the judicious use of faction fittings to save on CPU enough to fit the dissolution sequencer. If you don’t want to bother, just fit a CPU efficiency gate and deal with the reduced targeting range.

This fit has dual small deadspace shield boosters, which are extremely cap-efficient and cheapish. You can swap one with another shield boost amp (or use the slot for a utility mid) if you want to go cheaper but still cap-efficient, or upgrade to a single Pith booster for additional tanking ability.

Medium Capacitor Control Circuit I

Tank: 2000 DPS Guristas
Gank: 550DPS
Cap stable at 46%

This fit trades the sixth launcher for a huge capacitor, enabling the use of a large shield booster for a ridiculous amount of tanking. This fit should tank all Level 4 missions, provided the hardeners are adjusted accordingly.

Note the modules used for cap-stability – swapping in some capacitor rigs would make the fit less awkward if you wanted to roll with this fit all the time. Options with this fit involve using a cap booster instead of the cap-related modules, downgrading the shield booster size (or upgrading to a large deadspace booster) for cap stability, or just managing your capacitor by pulsing the shield booster.

Cap stable at 45%

This fit would be used for buddy-pair Tengus in wormhole space. Cap warfare might be an issue, in which case the low slots can be altered to provide more cap buffer, or tech 2 rigs installed. Due to the nature of wormhole space, it’s generally not worth pimping it out too much.

Tank: 240 DPS Omni
Gank: 505DPS (not using scourge fury)
Cap stable at 35%

This fit is from a friend’s exploration alt. He has this to say:

You can tweak it however to fit your wallet. e.g. Drop the expensive shield booster and passive EM hardener for 2 cheaper faction boosters. This fit works on the premise that you do Radar sites, otherwise you can drop the codebreaker too for a boost Amp. For me, this is also cap stable. I carry a EM Active hardener, Covert Subsystem and COCD in my hold for if I get a lowsec escalation.

What’s handy about exploration is that the modules you find can be used to pimp your Tengu further.

Travel

Obviously in Highsec you’re after a big buffer and good resists to prevent being alpha-striked on the Jita 4-4 undock, but elsewhere, you’ll want to take more stringent measures.

A fit dedicated to scouting and travel can be seen at Jester’s Trek.

How Do I Love Thee? Let me count the ways.

The Tengu is undoubtedly the most well-known of the Strategic Cruisers introduced in the Apocrypha expansion. The Strategic Cruisers (also known as T3 Cruisers) were also the last new sub-capital combat ships to be released into New Eden, and thus retain some semblance of newness.

Designed to be supremely configurable, strategic cruisers have been pressed into action in a variety of combat and non combat roles.

Some point to the relative unpopularity of certain racial subsystems as evidence that the T3 Experiment has failed and players only use the “best” fit and ignore the others. Perhaps that’s true; perhaps there are other factors at play, like relative balance between subsystems, or the dubious wisdom in configuring a very expensive ship to be a bad version of a much cheaper hull.

OMG a Caldari ship that actually looks vaguely good

Of all the strategic cruisers, the Caldari Tengu is acknowledged as a solid performer so when it came time to switch from training support skills to a more aggressive bent, I naturally gave some serious consideration towards training to fly one.

What decided it for me were the subsystems skills. Some subsystem skills are Int-Mem primary; others are Per-Will so it made sense to train whichever were easiest now, before the neural remap.

For most ships, its role is predetermined; recon ships are for PVP engagements; logistics ships are for repairing; Heavy Assault ships for pure damage. However, a multi-role vessel such as a T3 necessitates a different approach.

A T3 poses the question: what roles do you want it to play? for me, I narrowed it down to a few roles:

• HAC-like damage dealing for Sovereignty-related cosmic anomalies and belt ratting
• Tanking like a brick for harder DED-rated complexes
• Possibly a gang fit for either warfare links or (mutual) remote repair

An all-in-one exploration fit was discarded because I can easily swap ships, although some friends swear by their Tengu for high-sec exploration.

Similarly, a pvp fit was out of the question because I’d much rather lose a half dozen T2 ships than a single T3, not least because I would have had six times the number of fights.

So, Serps, I hear you say, why not just buy a Ship for each role? say, a CNR, an Ishtar and a basilisk?

Well, basically because I can’t fly them 😦 and anyway, what use is a T3 ship if you don’t change the subsystems from time to time?

With this in mind, I set about investigating the Caldari subsystems for purchase. Of course, I’ll have to choose at least one from each group, but since some of the subsystems are quite pricey, it’s worth taking the time to choose wisely.

Defensive Subsystems

As you’d expect, all the defensive subsystems affect defence, as well as providing different module slots.

Supplemental Screening

10% bonus to shield hitpoints per level

This is obviously the module of choice for PVP shield buffering: a buffer bonus, nice base shield amount, and two mid slots. I suppose you could make a passive tank fit but then the signature radius blows out and you lose a lot of the benefits to flying a small ship, as well as waste all the low slots on shield power relays instead of damage modules.
Good for: PVP buffer tanking
Buy? No

Adaptive Shielding

5% bonus to all shield resistances per level
10% bonus to shield transporter effectiveness per level

This is an intriguing module. It offers a high slot and a mid slot, but the shield resistance bonus compensates for the missing mid. It seems really good for remote repair setups, so depending on price, I’ll chalk this one up as a maybe.
Good For: Remote reps (wormholes)
Buy? Maybe

Amplification Node

10% bonus to shield booster effectiveness per level

Ah, this is nice: an excellent PvE tanking bonus; this will be the mainstay of my PvE fits.
Good For: PvE Solo tanking
Buy? Yes

Warfare Processor

5% bonus to effectiveness of Siege Warfare Links per subsystem skill level

Considering my siege warfare skills are terrible, I think I’ll delay this purchase, although I note that Tengus benefit greatly from each of the three types of Siege Warfare links. Fitting multiple warfare links will require a Command Processor, which is yet another long train, so this aspect of helping others will take a back seat, I fear. The missing second mid slot also means that a fleet boosting Tengu will be more fragile, which also doesn’t appeal.
Good For: Gang Boosting, getting awoxed by fleet members
Buy? No

Electronic Subsystems

The Electronics subsystems affect the targeting range, sensor strength and provide, it seems, a lot of mid slots.

CPU Efficiency Gate

5% bonus to CPU per level

T2 fitting a Tengu can be daunting at low skills like mine, so it’s good that this option is available. However, since its base CPU is pretty low, you need Caldari Engineering Subsystems III to even match the other subsystems, so you’re really only getting maybe 10% more rather than 25% more CPU. I appreciate the option of using this subsystem but I think I’ll give this a miss in favour of adjusting my fit downwards until my skills catch up.
Best For: Pilots who load up on missile rigs or T2 modules
Buy? No, but it’s cheap anyway

Dissolution Sequencer

15% bonus to ship sensor strength per level
5% bonus to targeting range per level

This subsystem provides resistance against ECM as well as longer targeting range for the heavy missiles I will be using. This is the best electronics sub yet.
Best For: Long range combat, especially vs Guristas rats
Buy? Yes

Obfuscation Manifold

10% bonus to ECM target jammer optimal range per level

ECM optimal range is good, since the only other cruiser with that bonus is the Blackbird with its tragically weak tank. By some accounts, the Tengu could be put to use as a durable ECM boat for incursions or wormhole space, but I will give this a miss for the time being
Best For: Pilots who want a really tanky Falcon
Buy? No

Emergent Locus Analyzer

10% increase to scan strength of probes per level
20% bonus to range and velocity of tractor beams per level

Role Bonus: -99% reduced CPU need for Scan Probe Launchers

I don’t need an exploration fit at the moment, but if I did, this would be awesome. 4 mid slots allow for exploration modules, or extra-tough tank for a brick fit. I will keep this one in mind.
Best For: Exploration, or really tanky fits
Buy? Yes, because it’s cheap.

Engineering Subsystems

Augmented Capacitor Reservoir

5% bonus to capacitor capacity per level

Bonuses to capacitor would be a lot better if the Tengu didn’t use its mid slots for tanking, so I could fit a large capacitor battery on at 150% strength. Still, the extra high slot is desirable for damage, so I rate this a buy, especially since I’ll be starting out on much less dangerous sites like belt ratting.
Best For: Moar Damage
Buy? Yes

Capacitor Regeneration Matrix

5% reduction in capacitor recharge rate per level

The truly huge base capacitor size, coupled with the recharge rate bonus and a few Capacitor Control rigs make for a cruiser that can comfortably fit a permanently-running large shield booster for incredible amounts of tanking ability (In the ballbark of 1800 rat-specific damage, not adjusted for damage mitigation due to signature radius and speed). The extra low slot allows for a Power Diagnostic System, Damage Control or Capacitor Flux Coil/Capacitor Power Relay for additional ease of tanking.
Best For: tanking stupid amounts of incoming DPS
Buy? Later, when I need it

Power Core Multiplier

5% bonus to power output per level

A pilot chooses this for the turrets, but it’s widely known that Hybrid Turrets are underpowered, especially on Caldari ships which don’t get damage bonuses for them. Using this subsystem on this ship is a mistake.
Best For: Hybrid Turret fits
Buy? Hell no

Supplemental Coolant Injector

5% Reduction in the amount of heat damage absorbed by modules per level

Considering that the most-overheated module are weapon turrets, the fact that this subsystem doesn’t have an extra turret is a huge strike against it. I suppose that overheating mid slots is a viable niche for T3 cruisers in PvP, but since the ECM subsystems are a bit ordinary, the Tengu is probably not the best strategic cruiser to benefit from this subsystem.
Best For: Overheating mid slots
Buy? No; train your Strategic Cruiser skill more instead.

Offensive Subsystems

Accelerated Ejection Bay

5% bonus to kinetic missile damage per level
7.5% bonus to Heavy, Heavy Assault and Assault missile launcher rate of fire per level
10% bonus to heavy missile and heavy assault missile velocity per level

Five launchers and substantial bonuses to kinetic damage means a big thumbs-up.  No drones for smaller targets, but compensated by moar damage(tm) so it’s a wash. Focused bonuses lend themselves towards best use of faction or tech 2 ammunition.
Best For: violencing cruisers and larger.
Buy? Of course. This is why you bought a Tengu.

Magnetic Infusion Basin

5% bonus to medium hybrid turret damage per level
20% bonus to medium hybrid turret optimal range per level

If hybrids didn’t suck, then maybe this would deserve a second glance.
Best For: Masochists (i.e. those who like hybrid turrets)
Buy? not unless you like pain

Rifling Launcher Pattern

10% bonus to ECM target jammer strength per level
5% bonus to Heavy, Heavy Assault and Assault missile launcher rate of fire per level

Well, this has a drone bay, and the missile bonus is not restricted to Kinetic damage (although lower than the Accelerated Ejection Bay). This may be an option for long-range ECM configurations, where the damage type flexibility for PvP comes into play, and the drones can be used to keep tacklers away, but I remain unconvinced that it’s worthwhile outside of C5 and C6 wormholes.
Best For: do-it-all scenarios, tanky Falcon fits, people who can’t make decisions
Buy? No. There, decision made.

Covert Reconfiguration

5% bonus to missile launcher rate of fire per level
Role Bonus: 100% reduction in Cloaking Device CPU use

Who doesn’t like the Covert Ops Cloak? While it’s nice to have, I suspect I will fit it to fly my Tengu to its null-sec destination, then repackage it and send it back to Jita to sell.
Best For: Cloaky Tengus, travel Tengus and some styles of Ninja Ratting Tengus
Buy? Yes, then sell after use.

Propulsion Subsystems

Fuel Catalyst

10% bonus to afterburner speed per level

Well, it doesn’t go particularly fast at 160m/s base speed, but the 50% bonus adds up to a pretty decent speed tank. Considering that many Tengus fill their low slots full of Ballistic Control Systems, dropping a BCS for a speed module should push you faster than 800m/s for only a small drop in damage output if you feel the need for speed.
Best for: PvE
Buy? Yes

Gravitational Capacitor

15% bonus to warp speed per level
15% reduction in capacitor need when initiating warp per level

The highest base speed (175m/s) makes up for bonuses that don’t affect your play style very much. The fastest subsystem when a MWD is fitted.
Best for: MWD fits, loltastic racing Tengus, expensive salvage boats.
Buy? No

Intercalated Nanofibers

5% increased agility per level

A popular choice. Many players don’t use an afterburner or MWD, or care more about the align time than speed. I’ve yet to see whether this is an issue, but no doubt someone will eventually violence my boat and I’ll wish I had this fitted instead.
Best for: scared carebears, close-orbit HAM PvP fits
Buy? No, but I’ll regret it later

Interdiction Nullifier

5% increased agility per level
Role Bonus: Immunity to non-targeted interdiction

It’s missing a lot slot which means that your fit is slightly gimped by using this (although nowhere near as gimped as an armour tanking ship) and it’s pretty slow and not particularly agile, but the ability to ignore warp bubbles is pretty awesome.
Best for: travel Tengus
Buy? Sure, it’s cheap
