A recent tiff with Raubvogle led me to explain that high atlitude bombers are not invincible. I've shot them down with alot of success (they always seems to be a bomber headed to my city every hour).
I've also mostly been attacted by what I must guess are new players. None have studied the problems of making an attack on a bomber, and almost all come from behind in a straight and level attack. I assume that not many people actually have flown bombers themselves and do not know how easy it is to shoot somebody down like that.
So, here is my list of cardinal rules for shooting down bombers.
1. Do not attack from behind or below (which Raub did twice, and the results are fairly obvious. In his defense it was quite evident he was furious with me, and wanted to shoot me ASAP).
2. Don't always attack. Yes, I said that. Don't shoot at the bomber. Just by being there in a fighter, you have nuetered that bomber from dropping his bombs. My brother saved our CV fleet simply by flying between the fleet and an enemy bomber, acting like a blocker.
3. Attack in pairs. One from the left, one from the right. The fighter that gets shot at should break off a bit, while the other goes in for the kill. This is a surefire tactic. The only defense is a bomber formation.
4. Use the right aircraft. Latewar German fighters are designed for bomber intercept. Use the Fw190D9 or better yet the Bf109G10 with gun pods and the 30mm cannon.
5. WEP to altitude. I did a test and the Bf109G10 with gun pods starting on the runway and it will run out of WEP when it hits 36k of altitude. Shadow your target untill your engine cools off a bit to WEP in and make your attack runs.
6. Patience. Wait for reinforcments, and definetly wait untill your above your enemy. Call for help, and call often. Somebody will usually come to your aid (use him as that distraction I mentioned above).
7. Use sweeping attack runs. Never fly straight at the enemy. Come from the sides, take a short shot, and get out. Repeat a few times. Most of my bomber kills are not in the first try.
8. Shoot the wing off. A wing is easier to destroy than the whole bomber. Make a pact with any reinforcements to agree on a wing to shoot at. In WarBirds my JG51 squad all agreed ahead of time that the righthand wing is now and forever the target. No discussion in combat required. Shoot at the wingtip.
9. Don't not use those funky Luftwaffe rockets. They'll slow you down. Take guns instead.
10. Fake passes. Make a few runs, but never fly directly at the bomber, and not in a constant direction either. Make him waste ammo, though this is dangerous (I've lost alierons and engine oil this way).
The main key for success is a partner. One has to distract the gunner to let the second fighter sail in for a easy kill.
