I’ve got a lot of nostalgia for battlewagons myself, but their day came and went. They had their heyday as the queens of the sea before carriers began to replace them. They were once the epitome of technology, a heavily armored warship able to fire the largest of caliber shells further than any other ship could reach with a pretty good accuracy for the day.
Much as there is a conventional wisdom that battleships were obsolete in WW2, they were anything but. They were no longer the queen of the seas, that mantle was passed to aircraft carriers, but there were a lot of surface engagements that occurred, particularly during nighttime. For example 4 of the 10 battleships lost by Japan during WW2 were lost to nighttime surface engagements. These were days when aircraft were pretty much neutered at night. Even without that, the days of the battleship were clearly numbered; nobody built battleships after WW2 ended. Post WW2, the entirety of their reason for existing became shore bombardment.
While nothing can beat the crap out of shore targets like a battleship can, it’s become a very niche role. The cost of maintaining a battleship for service is very high, in large part due to their age and manning requirements. No doubt a purposely designed battleship from the ground up today would require far less crew, and maintenance might be lower, but it would require a huge investment, and the only return would be shore bombardment. Again, it’s a very niche role in the modern world for a very large cost
Much as I get nostalgic about battlewagons, even the reactivation of the Iowas during the Reagan administration was probably anachronistic and a huge waste of money in the end. Their only real combat use after reactivation was to bombard Kuwaiti shores as a diversion, no amphibious assault was planned.
Battleships no longer control the seas, they are very expensive to maintain, and the only thing that they can do better than any other naval ship is shore bombardment - though with the advances in technology, it’s far too close of a game with carrier aircraft that now can operate at night and in all weather conditions and can drop ordinance far, far more accurately than in WW2. For the very ,very few countries that can afford to build carriers or battleships, what would be the more logical choice for the investment - a battleship which can only beat a carrier (possibly) at shore bombardment or an aircraft carrier which is *extremely *versatile and very good at pretty much anything it can do - which cover a **lot ** of ground, from sea denial to sea control to tactical air strikes to strategic air strikes far, far out of range of a battleship’s guns.
From pure nostalgia for all that they did at one time, I’d love to see a role for battleships in the modern world, but frankly there isn’t one.
