Ok so here is the difference between the Typhoon and Raven, plugged em into EvEHQ, but heres the stats:

Typhoon All 0 No Fitting
Minmatar Battleship Skill Bonuses:
+5% to Cruise and Torpedo launcher rate of fire
+5% Cruise Missile and Torpedo explosion velocity

Slot layout: 7H, 5M, 7L; 0 turrets, 6 launchers
Fittings: 12500 PWG, 640 CPU
Defense (shields / armor / hull) : 6500 / 6000 / 6000 {23,854 EHP - This takes into acount resists}
Capacitor (amount / recharge rate / cap per second) : 5400GJ / 1087s / 4.97
Mobility (max velocity / agility / mass / align time): 130ms / .11 / 103600000 / 15.8s
Drones (bandwidth / bay): 100MBit / 100m3
Targeting (max targeting range / Scan Resolution / Max Locked targets): 65km / 115mm / 7
Sensor strength: 19 Ladar Sensor Strength
Signature radius: 350m

Raven All 0 No Fitting
Caldari Battleship Skill Bonuses:
+5% bonus to Cruise and Torpedo Launcher rate of fire
+10% bonus to Cruise Missile Torpedo Velocity

Slot layout: 7H, 7M, 5L; 0 turrets , 6 launchers
Fittings: 11000 PWG, 750 CPU
Defense (shields / armor / hull) : 6800 / 5800 / 6400 {24,372 EHP - This takes into acount resists}
Capacitor (amount / recharge rate / recharge per second) : 5500GJ / 1160s / 4.74
Mobility (max velocity / agility / mass / align time): 113ms / .12 / 99300000 / 16.52s
Drones (bandwidth / bay): 50MBit / 75m3
Targeting (max targeting range / Scan Resolution / Max Locked targets): 75km / 85mm / 7
Sensor strength: 22 Gravimetric
Signature radius: 420m

Ok so we can see here that the Typhoon is faster but has less tank than the Raven with base 0

Now the Typhoon is going to be slowed a hell of alot once you start throwing armour plates on it, the reason you dont shield fit it is because its tank lacks in comparison to the raven when fitted with shields.

Mobility (max velocity / agility / mass / align time): 154.38ms (1,064.03ms MWD) / .07 / 103600000 / 11.23s (16.38s MWD)
Signature radius: 350m (2100m MWD)

Raven All 5 With Fitting
High: x6 Torpedo Launcher II, x1 Heavy Unstable Power Fluctuator I
Medium: x1 Prototype 100MN MicroWarpdrive I, x1 Warp Disruptor II, x1 Phased Weapon Navigation Array Generation Exatron I, x1 Heavy Electrochemical Cap Booster I,x2 Adaptive Invulnerability Field II, x1 Large Shield Extender II
Low: x1 Damage Control II, x3 Ballistic Control II, x1 Nanofiber Internal Structure II
Rigs: x1 Large Anti-EM Screen Reinforcer I, x2 Large Core Defense Field Extender I

Defense (shields / armor / hull) : 12,465 / 5800 / 5120 {63,260 EHP - This takes into acount resists}
Mobility (max velocity / agility / mass / align time): 154.53ms (1,124.85ms MWD) / .06 / 99300000 / 9.39s (14.12s MWD)
Signature radius: 501m (2906m MWD)

Raven is faster than the Typhoon once fitted, but less tank, te Raven also has much better agility and align time so it can out turn the typhoon allowing a kitting orbit to work, meaning the Typhoon wont catch the Raven without Faction Webs and Skirmish Links.

I hope you guys can now see what i have been saying in previous posts. The raven could deserve the tank that got taken away from it back though, cause my Drake has 20K more EHP buffer than it.
