Why Modern weapons (especially Earth Bet's) are less than effective on Abyssals than one would hope
It also doesn't help that Modern naval weapons are actually lower-yield than the massive shells that BBs used to lob.
The Yamato and Musashi were the two biggest, strongest, most armored battleships ever built... And each was sunk by US aircraft peppering them with bombs, rockets, and torpedoes. Musashi at Leyte, and Yamato in the Japanese's last stand (where only 10 US aircraft were shot down, out of hundreds). Their armor was effectively useless against the sheer
numbers that aviation could provide: Destroyers could fire a few torpedoes at a time, and cruisers or battleships could have maybe a dozen guns pointed at you. a carrier could have dozens of planes (with rockets, machine guns, bombs or torpedoes) in the air at once, while staying far enough away to be safe from surface fire, and render your main guns useless.
With heavy armor being of little use against planes, damage avoidance became the new meta, so to speak. Anti-Air and Anti-Missile defense, as well as radar avoidance became more important than actual armor, and if you're already avoiding damage, your armor is just slowing you down (and adding to materials costs).
Less armor means that modern naval weapons just don't
need to have that level of punch anymore. Why hit a ship with a 3,000 pound shell (Yamato/Musashi's shells)- much less a
nuclear shell such as the "Katies" designed for the four Iowa-class battleships- when a rocket with half (if that) of the explosive yield will do just as well? Especially when you need to unleash a swarm of said rockets to overcome the enemy's defenses anyway.
... With that said, there are some people looking at putting guns back on ships. Namely railguns.
I'm still holding out hope for Battleship Dinah. There's just something funny about the adorable tiny girl being the biggest gun in the room.
No, no. Dinah shouldn't be a Battleship... She should be one of Taffy 3's ships.
Why? Just imagine Coil having captured her, and brought her into his base... Only for her to tear through his defenses like paper. Then, once she's free, he finds out that she's not even a full-on destroyer; "just" a destroyer escort.
