I thought about three rigs that adds a slot to your Ship.

Only one of each rig can be mounted.
Required skill: Jury Rigging.

High slot Rig
Reduce the ship's agility.

Med Slot Rig
Reduce the Armor HP

Low Slot Rig
Reduce the Shield HP

Stealth Systems Enhancer rig - Calibration 200 - 99% reduction to the CPU need of the Covert Ops cloaking device. - Electronics Superiority Rigs
Stealth Jump Drive rig - Calibration 100 - Gives the ability to jump through a Covert Jump Portal Generator - Electronics Superiority Rigs
Stealth Signature Absorber rig - Calibration 150 - Reduces the ship's signature radius by 10% - Astronautic Rigs
Black Ops Cloaking Device - High slot - Fits to Black Ops ships and allows them to warp while cloaked. No penalties to scan resolution or speed.
Scan Absorption Paint - low slot module - Reduces sig radius by 10% - passive module
Scan Suppression System - medium slot module - Reduces sig radius by 20% - active module (same cap needs as ECCM medium slot modules)

One of the things the game lacks is what I saw years ago when I was playing Descent Freespace and/or Homeworld Complex. Flaks. Since the game includes projectiles, it wouldn't be absurd to include flaks. You wouldn't approach to a shivan ship without fear when long range/short range flaks are locked on you.

Flak Cannon (Overall): A delayed projectile, like missiles, but won't follow. It is fired as-is, from point A to B, if you are not there, you won't get hit. Eve already has the mechanics for this (bombs). It's resolution determines how further AoE damage you get. It has very fast rate of fire and consumes your ammo like there is no tomorrow (overloading it makes sure this will happen) Playing more angular game will help you to survive.
All flaks have very long falloff and should have a short optimal. If enemy is burning towards you from 100km without changing it's direction or speed, they will have trouble. If they just choose to orbit you @ 10km and saying "haha this smartbomb dominix is going to die with this 40 frigates", and if there is a flak equipped, watch the show.

- Flaks also have explosion velocity like missiles, but much faster.
- Explosion radius is lower than missiles.
- Travel velocity is faster than missiles, but lower than projectile ammo (visible while travelling), so the closer you are to the flak owner, the harder to escape by manuavering.
- Flaks' damage is joke when only one equipped. It should get exponentially more dangerous when you equip more and more (like when 8 frigate is much dangerous against a battleship than only one, the reverse role). So, each flak cannon you equip increases flak damage and explosion radius something like 1.75x, changes with meta of item.
- Flaks can be equipped with all types of damage. EMP/Therm/Kin/Exp.
- Tech II flak cannons can be equipped with webber ammo, when explodes in area, slows the targets for very short amount of time. (Since it is launched very rapidly, it can apply this one after another)
- Because of their fast rate, they should consume a lot of powergrid.
- Since it is only fire&forget gun, it should consume little cpu.
- Reloading ammo bay of an empty flak gun should take long time (20-30 secs).
- Its ammo bay should be big.

--High Slot--
40mm flak cannon (can be fit on destroyers)
80mm flak cannon (can be fit on cruisers)
Dual 80mm flak cannon (battlecruiser)
Quad 80mm flak cannon (battleship)
Octuple 80mm capital flak cannon (capital ships)

For working modern physics, I highly suggest checking the flak frigate, flak destroyer, cruiser with flak cannons, battlecruiser/battleships with rapid sweeper systems(flaks) and finally mothership (capital ship) with rapid sweeper system in latest homeworld 2 complex mod.
Here is a link to very short youtube video where a battlecruiser is battling against corvettes (a carrier vs fighters/frigates equavalent for eve): Flak fight

I raped a lot of BS while roaming with tons of frigs. There is something missing in the game. A fearsome feeling. A feeling that reminds me the danger of approaching to bigger hulls. Drones shouldn't be the only answer. A "battleship" should have much more gun slots. More generalized, the bigger the ship, the more it can(should) equip. Not only 400 resolution guns, also smaller gun slots. "Fear from the big fish" concept shouldn't be destroyed while keeping "protect the small guy so they can enjoy". There must be tools for those who are using big hulls against massive surround situations. I don't say everyone in a bs hull should kill everything smaller, but not being able to touch frigates with a ship geared for "battle" makes me wonder...

Back to the concept, flaks might make this game a little bit more challenging when considering battles like tons of small ships to larger types of ships. It is one more way (or tool) to defend what seems "undefendable".

Oh yes lets make a game where nobody can find nobody and where no weapon can hit...
I would love to fly a Covert Ops Harbinger with a cruiser signature ;-)
Perharps, the T2 covert ops would become useless, but nevermind.

I had a feeling that this was suggested before, but anyway, how about marine frigates?

Marine Frigate, Base stats H:300, A:200, S:200, signature: 29 m2.
1 high slots
2 med slots
1 low slots
Marine Bay Capacity: 10 marines (upgradable with skills)
cpu and powergrid is low for an afterburner or mwd.

Role Bonuses:
- Can attach to any cruiser or bigger ship with its strong magnets.
- Can equip Hull Penetration Laser

Attach bonuses:
- %15 to 75 decreased agility to attached ship
- Speed penalty to Cruisers: %75, Battlecruisers: %60, Battleships: %45, capitals: %30, supercaps: %15
- Target ship will unable to use warp systems of "any" kind, including mwd.
- Only one marine frigate attachment per target is possible.
- Marine frigate cannot be shot by guns of any kind. Only drones/fighters will be able to shoot after attachment.

High Slot Item: Hull Penetration Laser I - Charge: Marines
- Can only target cruiser class or bigger ships.
- Can only target ships which host frigate attached succesfully.
- When activated, starts penetrating hull of attached ship. Depending on ship size, penetration time is varied between 2 min - 10 min.
- After penetration, marines will be sent from marine bay, overtake time is [target ship crew / marine count] minutes.
- Marines are consumed during the process.

After successful overtake, target ship's player will be ejected from the ship and unable to board back again next 15 minutes.

---

This frigate is useless and very fragile by itself. It needs very strong fleet communication in order to survive and overtake.

I don't know if anywhere else have uses for this, but finally, "passengers" will mean something and maybe there will be a passenger bay which player can bring marines into it to defend against this frigate. If you have more soldiers, marine frigate will fail to overtake your ship. How many soldiers you can board will depend on your soldier management skills (a new skill?)

Is this another opening for DUST 514? Should probably have a requirement that the target ship be moving no faster than 5 m/s because attaching to a ship at high speed is extremely dangerous. There is always the issue of getting through the shields when even a carrier hitting a frig while dropping out of warp cannot get through its shields to cause hull damage.

That said, I disagree about the warp/MWD disabling and about the limit on number of frigate attachments limitation. The Marines should cause ship damage in the form of heat damage and structure damage as the fight progresses. In addition to the frigate attaching to the ship, drones could carry the Marines to the target ship and attach themselves to it, and then return to pickup another Marine. Light carries 1, medium 2, and heavy drone carries 3 Marines.

Is the purpose of this to end Titan battles quicker? or even capture Titans? or captil ships.
