When im trying to dive bomb a ship in PF i dont seem to hit many times. Whats the best way to hit your target ?

Sight point ?
Altitude to release bomb ?

And why/what are those numbers on the bombsight. I cant see any purpose for them.

im having trouble dive bombing too http://forums.ubi.com/groupee_common/emoticons/icon_frown.gif i think what u need to do is set up your plane in a straight vertical dive & then release bombs when you feel the need to. a good alltitude i find good to dive from is 2.500m.
also try dive bomb practice on large ground objects (hangers, buildings)then work your way down to smaller objects like aircraft, tanks good luck http://forums.ubi.com/groupee_common/emoticons/icon_wink.gif

Most of it has to do with practice. I can't say anything about dive bombing in a SBD but I have dive bombed with the Stuka and with other aircraft and its a bit of a trial and error process till you get a handle on how it works.

With the SBD, I've read they initiated a full 90 degree dive. Sight the target through the gunsight and drop somewhere between 900 and 400 meters.

All of the info I've read on SBD divebombing has been this.

Standard proceedure:
Approach target from the sun when possible.
Start dive from approx.14,000-15,000 feet.
Dive angle @ 70 degrees.
Release at about 1500 Feet and pull up.
Level out at about 500 Ft and egress the target area. (when bombing carriers with escorts, pilots often levels out almost on the deck and stayed there as they flew in between the escorts to leave. As the escorts fired at the egressing planes they would often hit each other as the planes flew between them, if they didn't stop firing at that time.)

As for sighting, I haven't read anything on that. One technique that was developed was known as "pitching". This was done by releasing the bomb just as the pilot pulled back on the stick to level off, which gave the bomb a bit more forward tragectory.

I would try using the gun site and "pitch" the bomb on release, if you are hitting short of the target.

I should note that I haven't mastered DB'ing either. Just sharing what the real pilots did.

OH yeah, and they didn't always hit the target either. http://forums.ubi.com/groupee_common/emoticons/icon_wink.gif

20 feet? Really? I thought only the Japanese did that!

Sorry, could not resist.

Hitting the target seems to me is all about "feeling" the sight does not help me much. Tried the jap divebomber but it looks like the pilot forgot too remove the cap on the sight. I could not see anything through it. Anyone else have the same problem with the jap plane ?

If it's like other SBDs I've flown online (WB) you push over from ~14k feet (12-14k was stadard for USN I think). Pop dive brakes, throttle down. Get into sight, and trim up the plane so the sight is steady. The bomb is goiing to go where the sight is when the the stick is unloaded, so if you are "driving" the plane at the time, you're gonna miss unless you get used to where the bomb goes under these conditions. The 1500-2500ft release alt sounds about right. drop, close dive brakes, and get the hell out of dodge.

Tried trimming the plane and that was a real help. Not fighting the stick seems to have improved my aim. Now i only want someone to remove the cap on the jap plane http://forums.ubi.com/groupee_common/emoticons/icon_smile.gif

is it control-d---that was reticle in il-2, right? (don't fly LW much)

Look through the key mapping, and check the keys for anythign that looks gunsight or bombsight related and try and figure it out.

Ya got me stans. LOL

I corrected it, and tater was right about the initial dive start Alt. 20,000 ft was the usuaul alt that the SBD's flew on their way to a target area. In the Battle of Midway, VB6 climbed to this altitude at the start of their trip to find the enemy, but had to drop down to around 18,000 ft due to some of the pilots were having problems with their oxygen.

Also, when possible dive bombers attacked ships from astern. Then the ship was only moving bottom to top in the sight, so you only need to line up in one direction, and if you are a little long or short, it'll still hit.

The numbers in the Site are Mills. These are legends that indicate the size in milliradians (Mills) of the particular ring.

How to hit a target ?
Other than straight vertical each release point will vary depending on things like Weapon ballistics,TAS,Altitude, Angle of Attack, Release wind, Wind during bomb time of flight etc.

Real world manual bombing requires exact planning to allow for all these factors. This planning typically gives the pilot a mills depression value to set on the sight, or Mills offset to place the site from the target ("Combat offset"). In other words given these conditions I place the set/place the site here. Then you have to fly your aeroplane to the EXACT release point you used for calculation, any error will result in bomb impact errors. So is it any wonder in Manual bombing why you dont hit anything ?

So for DB reduce the variables. Get rid of any dive angle/altitude/Angle of Attack variables by going vertical. In a pure vertical release all you need to worry about is Pull out altitude (lest you smite the water,Min fuse arming time .. though not applicable in FB/PF).

If the target is stationary then Pipper on is the correct release Site picture. If the target is moving then you need to make an allowance for target motion and release the bomb with the pipper a certain amount ahead of the ship along its axis of motion. As a rule of thumb try 2mills per Knot.
So a Ship moving at say 20Knots will need 40mills of lead.
(The lower the release altitude the lower the lead requirement)

Practice Practice Practice. You need consistent technique every time.

S! All,

UFF DA!!! All this talk about releases!! Well c'mon U.S.of A release!! For now THE ONLY release I am particularly caring about is the GAMES release!! Then I will woik on the bomb/torp release!!

But I dont envy.Cuz the ppl who have it now are the post-post-beta testers. C'mon every1 who has it,FIND THOSE BUGS!!!! But have mad fun finding them ok?

Dive bombing is still bombing, remember it.
U can succeed in bombing by diving in any angle, and vertical diving is only a way to increase the bombing accuracy.
If u don't diving vertically, release the bombs just after you try to pull up, and the delay is mainly according to your experience.
