Its a Trump impression of the Tromp destroyer in World of Warships. Tromp is notorious for being a bad or meme pick in the game and because of that the community often joke that it is in fact a great ship.

Tromp is the best ship, it has all the best shells. No other ship has better shells, believe me. It has the best shells and the best speed, you wouldn't believe it. they told me "It's impossible, it's too good!" But it is, folks, it is, and you'll get tired of winning. We're gonna do so much winning, believe me, you're gonna get tired of it. You're gonna say "please, Wargaming, it's too much! We're winning so much with Tromp we can't take it anymore!" But you're gonna keep winning and it's gonna be awesome, and we're gonna build a great torpedo wall, a beautiful wall, with the best torpedoes, and we're gonna make War Thunder pay for it! And we need the wall, because the enemy team isn't sending us their best. They're kill stealers, they're trolls and some, I believe, may be good players. But we can't take them. It's a scam, folks. So we'll build a torpedo wall, the greatest torpedo wall ever 

Liar. You're a liar and you know it. Tromp is the best ship, it has all the best shells. No other ship has better shells, believe me. It has the best shells and the best speed, you wouldn't believe it. they told me "It's impossible, it's too good!" But it is, folks, it is, and you'll get tired of winning. We're gonna do so much winning, believe me, you're gonna get tired of it. You're gonna say "please, Wargaming, it's too much! We're winning so much with Tromp we can't take it anymore!" But you're gonna keep winning and it's gonna be awesome, and we're gonna build a great torpedo wall, a beautiful wall, with the best torpedoes, and we're gonna make War Thunder pay for it! And we need the wall, because the enemy team isn't sending us their best. They're kill stealers, they're trolls and some, I believe, may be good players. But we can't take them. It's a scam, folks. So we'll build a torpedo wall, the greatest torpedo wall ever. 

Tromp is actually one of the very strong ships too. The survivability is incredible due to its 30mm turtleback armour almost nobody knows about. Although your upper compartment drains HP in the beginning, after having no HP left it is almost like a french destroyer as the citadel compartment is protected from AP even from battleships like Montana. You can bounce of every cruiser in the game with that citadel armour while Ragnar can just get overmatched by Sevastopol AP. This also means that adrenaline rush is very strong as you just lose very little hp as soon as the upper compartments HP is drained. It almost has Ragnar gun HE DPM (when being nose in it has better DPM than Ragnar due to the 2 turrets in front) while compensating its downside of having almost 50% more alpha damage while having incredible 70s stock reload on 6 12km 15kdmg and 71kts torps. I'm not sure why Ragnar is banned but Tromp isn't, it just shows that the devs can't read their own numbers, play the game or listen to the community. That DPM is almost 80% of the Somers torp DPM while somers has horrible guns and slower torps. And then we even get a +25% speed boost which makes it very manouverable. On the top as a gimmick you get the Airstrike with incredible 266k (stock) DPM which can set fires on anything you shot so far making it the perfect firestarter. If you put it together with a ship having smoke it can easily kill any Annapolis (which has less than just double your airstrike DPM in HE). 

Its a World of Warships (WoW) copypasta that started from an analysis of the ships in WoW and a flawed balance suggestion. The OP was incapable of receiving feedback and argued with every commenter which led to the now iconic “Rangar is inherently underpowerd” meme.

Rangar is inherently underpowered. It lacks the necessary attributes to make meaningful impact on match result. No burst damage to speak of, split turrets, and yet still retains a fragile platform.

I would take 1 Conqueror..Thunderer or 1 DM or even 1 of just about any CA over 2 Ragnars on my team any day of the week.

Now... If WG gave it the specialized repair party of the Nestrashimy ( and 1 more base charge).... And maybe a few more thousand HP if could make up for where it is seriously lacking with longevity.
