In a recent game, I was trying to do amphibious invasions against a couple tiny-island cities the AI controlled. These two cities were spaced nicely between me and the long, skinny continent that the AI's main cities were located upon, although I could have bypassed them by going a long way around. The fact that they were located in such a defensive position made me attempt to take them rather than trying to form a beachhead and invade at a different location. In retrospect I should have attempted to buy out a nearby CS, land there, and then launch a navy-supported invasion across the land instead. That way I could have had multiple AA guns to defend the rest of the army. I should also note that I was using Thal's Vanilla Enhanced mod which makes the small islands more useful than automatic razes, but it also doesn't affect air missions as far as I know.

I did also forget that carriers could have escorted my fighters much closer to the invading infantry units.

I had one of the cities bombed down to 1 HP with battleships and destroyers, but I could never get an appropriate land unit close enough to capture it. Even when I had my fighters on the intercept mission and a few squares away from the embarked land unit, every turn that I had an embarked unit a turn from capturing, I'd get a message saying I was bombarded and destroyed by an enemy fighter. What radius does the intercept mission protect? Just the city itself?

Is there any other way to protect embarked land units for an invasion other than send like 6 units all at once and hoping a couple survive to take the city?

Edited my answer to match the new question details and a few thoughts I had in the interim. –  agent86 Jan 11 '12 at 20:01
    
I really think this should be separated into two questions - one asking what the fighter interception range is, and the other asking for good ways to conquer small islands defended by a lot of air units. Both are great questions and I will upvote them both :) –  Oak Jan 11 '12 at 21:16

I believe that all ground units that are air-intercept capable can protect in a radius 2 hexes around them. According to research done by Oak, air units can intercept anywhere in their attack range. A single ground or air anti-air unit can only intercept once per turn. Interception does not guarantee destruction, and it's possible that your unit will still be injured or destroyed even if the intercept is successful.

My strategy when assaulting a naval stronghold such as this is to bring overwhelming force, and plan to lose a few units. (This strategy would certainly be historically accurate...)

If air units are an issue, are you bringing in adequate ground-to-air (and/or sea-to-air) defenses? Carriers can store fighters that can intercept enemy fighters attacking your land and naval units.

I would suggest setting up some carriers and other ships to protect your embarked land units from enemy air and sea units while they get into position. It's not 100% clear from your question, but you are aware that you can attack the city while embarked, yes? Otherwise you've got another turn delay where your unit is vulnerable when you disembark.

As I suggested in the comments, I'd also consider choosing a different tactic or priority target if you can. Small 1 or 2 hex island cities aren't generally high value targets, and their production pales in comparison to a city near forests and hills. Plus, they're hard to assault (as you've noticed) and if the map isn't all islands, fighting the brunt of their forces in a sea/air engagement by building a bunch of ships you don't have a use for once you capture the islands might not be the best use of your military resources.

If you can bypass these islands, you might be better off capturing some of their higher value cities inland, thereby crippling their war machine. Who knows, they may even offer you the islands when they beg for peace... :)

I was attempting to take a couple 1-2 tile islands completely surrounded by water at radius 5 or so. Land based AA defenses weren't an option here. –  Mark B Jan 10 '12 at 18:05
    
It's surprising that with such a setup they'd have much of a military. Getting production on tiny islands is tough work. It seems like if you can import enough units to blockade them, they'll eventually wear down. You might also want to press the attack on another front, to get them to move their air units to an area that's more strategically easier for you to assault. –  agent86 Jan 10 '12 at 18:22
    
Your answer and comment make me realize things were more complicated that I originally realized. I'll try to edit the question with more detail a bit later as I have time. It's still very helpful though. –  Mark B Jan 10 '12 at 18:30

@Agent Production can come from anywhere for air units, since they can rebase from quite a distance. –  bwarner Jan 10 '12 at 18:52
    
@bwarner, yeah. That's why I suggested blockading or pressing the attack on another front. No use fighting a war that's high in losses for an outlying colony in potentially poor position when you can take out the actual production facility elsewhere. This is getting heavily speculative though, since we don't know the specific scenario :) –  agent86 Jan 10 '12 at 20:54

Air interception is based on the range of the fighter. If you promote the unit with range (+2). You are increasing the range at which the fighter will intercept other fighters. Interception range is at the hex the enemy is attacking, not the flight path taken.

As Oak says in the comments below... "interception doesn't stop the plane from attacking, it only damages it while it attacks. So your embarked units could have still died even if their attackers were intercepted."

I wish to add to that.,I have observed less damage on the target when my fighter is intercepted by another fighter or by other defences that is not the target, e.g. Destroyer. Untested, you could assume from that statement that a pack of destroyers (DS) is better than one because any one DS would have reduced damage as it is being defended by other the DS.

Captured Scenario

I managed to capture with save and load two scenarios where the enemy fighter was attacking one of my destroyers. Scenario 1 shows the fighter in range to defend the destroyer. Scenario 2 shows the fighter is just our of range.

Scenario 1.A - Fighter on carrier is in range to defend the destroyer. enter image description here Larger Img

Scenario 1.B - My fighter (yellow circle) is defending my destroyer from enemy fighter (red circle). enter image description here Larger Img

Scenario 2.A - I loaded the game and moved my carrier so the fighter was now out of range to defend my destroyer. enter image description here Larger Img

Scenario 2.B - The enemy fighter (red circle) attacks my destroyer. My defensive fighters remain on the carrier eating ice cream. enter image description here Larger Img

They absolutely didn't intercept at even the base range of 8, let alone with the +range protmotion. –  Mark B Jan 18 '12 at 7:21

@Mark interception doesn't stop the plane from attacking, it only damages it while it attacks. So your embarked units could have still died even if their attackers were intercepted. A fighter interceptions range is indeed equal to its attack range. –  Oak Jan 26 '12 at 1:52
