I mean you have this massive small-town sized ship (6000~ crew) and it's support ships, and then you have a bunch of agile, fast moving, speedboats that present very small targets that bounce across the waves that are capable of carrying enough explosives to put a hole in the hull...
Obviously the swarm of small things that are effectively man-piloted missiles are going to be able to take out the slow 200 million pound behemoth that requires 3-5 miles to turn around.
Carrier groups are specifically designed to combat these kinds of threats. That's why "carrier killer" missiles like China's DH-26 are hypersonic; it's because that's what you're supposed to have to do to overwhelm a carrier group.
Carrier groups are meant to take out proper ships, not small speedboats. You can have a hypersonic missile all you want, but when a speedboat can rapidly change speed and direction unlike even something small like cyclone-class patrol craft.
Change generic speedboat to fastboat and you have something that can do 30-90mph (50-80 knots) depending on wave conditions while the previously m entioned cyclone-class tops out at 40mph (35 knots).
Carrier groups aren't exactly in a tight circle around an aircraft carrier either and then you have to consider friendly fire (with deck guns/artillery) so enough much smaller craft can come zooming in and easily overwhelm any defensive capabilities.
Depending on distances and angle you might be firing a 62 caliber projectile directly at your own ships with a craft randomly adjusting course, in choppy waters. Software is only going to do so much to increase the odds of hitting your target and something like a deck gun is going to be used long before anti-ship missiles that cost many hundreds of thousands of dollars well into million dollar plus range a pop. Especially if you have a half dozen, a dozen, two dozen cheaply acquired speedboats/fast boats coming at you.
Naval warfare isn't much different now than it was hundreds of years ago for proper ships. Sure the projectiles can be laser guided and carry way more destructive potential while the ships can move under their own power but you're still talking about incredibly heavy ships that move slow and are bobbing up and down in the water.
Similarly put a dozen guys on performance dirt bikes and give them explosive backpacks and throw them at an M1 Abrams and unless you have one hell of a lucky gunner, one of those dozen people is going to get right up on that tank and at a minimum will render it immobile.
Naval ships are meant to fight other ships and in the case of the aircraft carrier itself, simply support a small fleet of aircraft. They are not designed, or intended to, fight multiple much smaller craft. Speedboats have very limited ranges, rarely leave coastal waters and can't carry any weapon system that poses a risk to naval vessels EXCEPT for shoulder-fired rockets and by acting as suicide man-piloted missiles laden with explosives.
I'm not sure where you're getting your information. Naval warfare has had more changes in the past 100 years then nearly any other point history. Like 100 years ago they didn't have aircraft carriers, the keel of the first one was laid 1924, and it wouldn't be until near the end of the Pacific theater that the supremacy of the carrier group was proven.
Like, your whole argument is equally applicable to torpedoes, except those are even harder to hit.
>Like, your whole argument is equally applicable to torpedoes, except those are even harder to hit.
Torpedos can cost a million bucks each, a stolen/commandeered/seized speedboat is free.
Torpedos are covered under ITAR and require quite a bit of sophistication to manufacture and are effectively limited to nations. Anyone can obtain a speedboat, or a dozen speedboats, and deploy them. Kinda like when the USS Cole was successfully attacked, leaving a 40x60 foot hole in the side, by a small fiberglass boat carrying several hundred pounds of explosives and modern day pirates usually use small fishing boats.
The Cole was literally moored for refueling, not quite at peak readiness, and not really what we're talking about here.
But the whole point of how carrier defenses work is to not wait until they're literally on top of you (like on your example of shooting your own ships). Speed boats are stupid loud on SONAR, so you should detect and destroy them before they can even see the carrier group.
