Why do different naval ship types exist?

I can obviously tell why you’d want a dedicated aircraft from a not, but trying to wrap my head around why you’d for example in the royal navy (UK) frigates are slightly specialised for anti submarine warfare whilst destroyers are slightly specialised for anti air warfare, why not have a single dedicated escort?.

And to mention historically, why would you have smaller ships alongside battleships (for example destroyers and torpedo boats in the battle of Jutland) when the battleships have a dedicated armament to combat destroyers?

Sorry if this seems stupid, I’m just doing my best to understand 🙂

As the old saying goes a jack of all trades is a master of none, in theory a specialised ship with a dedicated role and a crew trained for that role will outperform a multi role ship in that tasking.

Smaller ships are better closer to shore. Less draft. You cant bring battleships into less then 30 feet of water (i made up the number since it varies so much, you get the idea). Conversely you want big ships to cross oceans.

In WWII, part of a destroyers mission was to run screen for cruisers and battleships. Its better mission wise if they take torpedoes than the big ships.

You can only fit a certain amount of stuff on a ship guns, missiles torpedoes, radar, sonar, other electronics, helicopters etc. So if the ship specialises in a role like anti aircraft they can have a special antiaircraft radar and anti aircraft guns and missiles all on a relatively small ship. Alternatively they can have a powerful sonar and an anti submarine helicopter and antisubmarine weapons fitted.
