Is it strong still?

To refute Mr. Schaub's answer (IMHO), the USS New Jersey was one of four IOWA-class battleships built during WW2 (USS Missouri, USS Iowa, USS New Jersey, USS Wisconsin). Technically, yes they are now obsolete, but a great deal of controversy still exists. Costs to modernize & upgrade the Missouri & Wisconsin, last deployed in the 1991 Gulf War, raised questions about cost & relevance of the battleship in modern naval warfare. The need for 16" guns & numerous other heavy armaments versus missiles & drones, and vulnerability of the Iowa-class is clear. IMHO, the need for the battleship is still legitimate because it is potentially a massive platform for deployment of ultra-modern heavy weaponry (i.e. rail gun). Nonetheless, nothing today exists that is stronger, tougher, and capable of delivering sheer firepower than these. It may take 18-24 months to modernize, but if you needed one & didn't have it, it would take 5 years to build from scratch.

I think it can still kick some major behind if needed. Would need to be broght back to seaworthy though. Those guns alone were pretty fearsome. Everyone keeps saying to not bump your head. I was able to make the whole tour with out a bump. And i climbed in the rear gun turret also!

Off course it's still strong ,it's an IOWA class battleship ,it's good for another 50-100 yrs . Murica !

Its old and obsolete. It would stand no chance in a war now. Its a neat tour but if your tall take something with you for a headache because there is a lot to duck.

It is still a relevant treat to naval forces as it is a lead ship of a battlegroup.
