ECL(25) Reynaud
Copy of the KM Emden. You can mount x2 3.5“/50 cal Model 1929 A AA guns on it. They have awesome range, and muzzle velocity, but on close ranges they aren't the best and you need really good gunners to use them.
PCL(38) Gamelin
I don't have it, but I suppose it's more or less useless like all other PCL.
PCA(53) Mandel
It's a Moltke copy with a nice paintjob. With the x2 12"/45 cal Model 1910 guns of the Courbet this ship has more firepower than any other PCA. You also have many options to mount strong anti air or anti submarine weapons to T slots, while it's still reasonably fast. That's why this ship is better than any CA, PCA, and BB1 in the game.
PBB(61) Dunkerque
It's the counterpart of the well known RN Dunkerque. This ship was made for rushing. With high level crew it's easy to maintain 25/42 Knt. and with it's semi blockshoting quads it's a very fun ship to play. It's possible to mount x2/x4 5.1"/45 cal Model 1932 A guns for AA purposes but it's better to have some HH instead. It has 8 support slots but there's only 4 slots on the ship. Unlike the other three PBB it's a real funship, not just a grinder.
EBB1(50) Danton
This ship intended to use x2 12"/45 cal Model 1906 guns wich are probably the best EBB1 guns in the game. They have BB3 range and great damage/shell. The problem is, that you can't mount more than two of them on the R slots. The T slots are probably the largest in the game (174 space), but you only have 3/side so they are more or less useless. It's possible to mount 5,1" quads for AA purposes but this option makes this ship too slow, and other AA or ASW guns just aren't strong enough if you have only 3 of them. It has 6 support slots.
EBB2(71) Provence
I don't have this ship, but as I know it's nice. It has twice as much x2 12"/45 cal Model 1906 guns like Danton which gives this ship great range and firepower. It has 7 support slots. The only problem with this ship is that there's a much better ship three levels above, that's called...
...EBB3(74) Le Harvre
The Beast. This ship can mantain 23/39 Knt.* That's enough to catch any BB5 and hit their fat asses with 16 barrels of 13.4"/45 cal Model 1912 guns. For more range, speed and some AW capability you can use Danton EBB guns, but I think this ship is made for terror quads. It has 7 support slots.
EBB3.5(84) Strasbourg'38
This is one of my favourite ships. Compared to the normal Strass it's a bit slower (25/42) bit it has a nice paintjob, and more place for a better FCS. With BB FCS III you have reasonable chance to hit the enemy with all your shells, and by two well aimed salvo it's possible to sink any BB1-3 and cripple the bigger ones. The third executes any ship in the game. For T slots still HH is the best option. It has 8 support slots but there's only 4 slots on the ship.
EBB4(96) Clemenceau
It's basically a Richellieu with one more support slot. I don't have it so I don't know what's the speedcap for it, but as I've seen so far, it used to go by 26/44 Knt. It has a plenty slots for secondary armament. Some HH is aways usefull. Since Richie is a good ship Clemenceau should be also nice.
EBB4.5(99) Jean Bart
It's a Richellieu but like all other EBB5 it can mount BB5 clone guns. In this case they are the 18.89"/45 cal Model 1941 quads from Alsace. The playstyle is similar to the Stass('38) but this ship is bigger, slower (24/40) and its shells have longer hangtime. Consider that Jean Bart is also a bigger threat so, you'll be never ignored by your enemy and this ship is quite fragile so don't rush like headless chickens! It has only 7 support slots like Richellieu.
EBB5(113) Thermidor
Compared to the BB5 Alsace it has a longer, but narrower hull and one more support slot. This ship didn't get a special gunset, but it got some accuracy buff. It misses its two big T slots from the sides, but as I see only a very few players use AA on MN Battleships so it's not a great problem.
ECV1(71) Bearn'44
It has a few more planes and one more (7) support slot compared to normal Bearn. It also has the ability to launch one more plane (8), so it makes the grind a little easier.
ECV2(87) Joffre'43
It also has a few more planes and one more support slot (8) compared to it's normal counterpart, like Bearn, but Joffre('43) can't launch more planes than the Joffre without zebra paintjob. I don't have it because I think it doesn't worth the coupon or medals.
PCV(100) Daladier
It's the copy of the KM Hindenburg. It has 10 huge R slots so in case of close combat it's not defenceless. So anyway, like all PCV it's rather a CV5.5 so if you used to play with carriers, sooner or later you'll need it. I already have it, but I couldn't try it, because my pilots aren't lvl100 yet.
5.1"/45 Model 1932 duals and quads
Theres only a little diference between the names of 5.1"/45 Model 1932 premium guns and the 5.1"/45 cal Model 1932 which is confusing. Premium versions are heavier but they have better muzzle velocity, shorter reload time. As I know only Gamelin, Mandel, Dunkerque, and Daladier can be equipped with these guns.
*According to ErwinJA it's possible to reach even 24/40.
Fell free to send me a pm if you notice any inaccuracy, typo or grammatical error. Also if you have additional information about the ships that I don't have yet, (Gamelin, Provence, Clemenceau, or Joffre('43)) please help me complete this post.
