There are no surprises with the Dunkerque. If you were hoping for some unique French flavour to be found in her consumables or modules, I didn't find any present here. The only option she has unique to Battleships at tier 6 is the option of swapping out her Spotting Aircraft for a Catapult Fighter, but that's hardly enough to get excited about. She does not get access to the Artillery Plotting Room 1 Modification. That remains American only.
Her Damage Control party conforms to the standard we've seen so far for German and Russo-Soviet Battleships. This provides a 15s immunity window and a 120s / 80s reset timer. Similarly, her Repair Party is also standard, restoring up to 14% of her maximum base HP per charge.

Objectively, there's not a lot to like about the Dunkerque. She pays a very big price for having all of her firepower easily accessed upon her snout. Bad armour, bad handling, bad camouflage, bad anti-aircraft guns, bad secondaries ... bad, bad, bad. So why the heck do I love her?
Would I Recommend?
Yeesh, this is going to be a tough one to recommend.
You'll get your money's worth here. Her accuracy and gun handling will make farming the damages (and thus the credits and experience) easy enough. At tier 6, you're not going to recoup tons of credits. Also, keep in mind that as a Battleship, you're likely going to be running with at least one premium consumable, so that's going to eat into your earnings. I found her a delight to play, but she doesn't have tremendous carry potential. So that in turn is going to hurt those looking to pad their win rates. She can do very well, but like the Molotov, you need to do well early with overwhelming ad strategically placed damage to effect a win.
She's the first French ship in the game. That's novel enough for many to grab her. She didn't have an illustrious career, so that tarnishes her worth, but at least she's a historical vessel.
I would pick her up for this alone. Her guns are a joy to use -- so much so that I am willing to forgive a whole lot of her flaws. I'll be putting a lot of play time into the Dunkerque.
There's thankfully few surprises here.

The Dunkerque uses a fairly standard set of Battleship skills for her tier.
