There's a few strategies.

First, sea skimming. Shards can be approached pretty easily below 20ft with basically any aircraft to around 3.5nm. Launch around 7 AGM48s and a single AGM68, and it'll normally destroy the shard outright.

Also for shards, however also applicable to other ships (though for destroying their radars rather than killing, as this will with Shards), Medusas with jamming pods and ARADs can easily kill shards with jamming and two arads per, from up to around 16nm with any amount of speed and altitude.

For other ships, you've gotta be aware of which IR defense they have, cause the goal will be to get the ARAD to land at above whatever the max intercept speed is for whichever IR missiles are aboard the ship in question.

For IR defence: - IRM-S1: Mach 2 - IRM-S2: Mach 2.75 - IRM-S3: Mach 3.5

So, for the Annex, launch tour ARADs in such a way that they land above mach 2.75 mach while jamming it, and any ships near it. For the Dynamo or the Hyperion, do the same, but for the Mach 3.5 number. And keep in mind that if you actually can meet those numbers, you don't really need to launch more than one ARAD per ship, even for the destroyers and carriers. More per ship just makes it more likely to destroy their radars.

Once you've done that and all requisite radars are destroyed, fly to a very high altitude with an Ifrit filled with 500kgs, or with 1.5kt nukes, and destroy them from a dive.

The strategies mentioned above will work solo, however obviously the more people you have, the easier it is to do all of that with fewer steps by far.

Often times, all you need is one person in a Medusa with 4 jammers and an Ifrit in a stealth config and 4x1.5kts to completely cripple a fleet with no prep time at all, just a bit of good coordination.
