Ships & Modules

I have a kind of multi-part question regarding a Cov Ops setup (Cheetah, in my case, but not limited to).

The roles I use it for:
Primary: All purpose shuttle, but main job is scanning wormholes and sigs in our w-space system. As such, it essentially have to have 2xgrav rigs, a cov ops cloak, and a probe launcher.

Secondary: we occasionally are under 'siege' or just simply have wh campers at our exits. I use this ship for running bubbles, which is relatively low risk in a cov ops EXCEPT when someone is using bombs. So far, I have not been tagged, but I am looking for a fit that might at least survive a single bomb. I essentially have all my lows (3) and mids (4) available.

Bomb mechanics question. A bomb does 6,400 damage of a particular type (increased up to 8,000 by skill), but appears to have a 400m explosion radius. Since my cov ops has ~52m radius, I only take about 1/8th damage, I presume, meaning about 1040 per bomb. I can get my EHP up to right at 3,200 against the worst damage type (thermal). Does this mean I can survive 3 bombs? Am I missing something? To get that EHP I am giving up a bit of speed - I have a T1 MWD, three small extenders in the mids and an ODI and 2xT2 RCU in the lows.

Against the Hound and the Purifier, I have quite a bit more EHP, but not enough to quite take a 4th bomb.

Am I missing some mechanics here? I kind of always assumed the first bomb that came may way would obliterate me, but maybe not....?

Thanks, I was totally forgetting the MAPCs, I rarely fit small ships for 'performance' anymore :).

I am probably going to go with a MSE and 2 resist amps (EM and Ex) since I see probably 90% Hounds and Purifiers. This saves me from trying to pulse three modules (2 invulns and an AB) then cloak. With my lack of coordination, I would probably just screw it up. And although it is rare that I would still be subject to bombs 10 seconds after cloaking, the Invulns would be off then and not help as much as the resists. Without a MWD, I am probably dead if they decloak me, so I am not too concerned about anything other than the initial pulse before I cloak. I am debating a DCU, which would give me a huge EHP (relatively speaking ofc - 7400 EM and 9400 exp, 4974 to weakest), but that is another mod to pulse, albeit one with a 30 sec duration.

As I understand it, when you jump through a gate or wh, the 'free' cloak that last until you move keeps you invincible, even to bombs, is that correct? Or are WHs different than gates?

OP, note that Shield Extender modules bloat your signature radius, by a flat number of meters per module. Not by much, but it's there. Damage Control Units, and Shield Hardeners, do not cause sig bloat.

And not that it applies to you, but shield rigs (purges and extenders) causes a percentage signature radius bloat.
