How to A-G with Su-27?

Hi!

 

A noob talking here. So how do you do bombings or rocket runs with the flanker without wobble? I can't hit anything.

The su-27 will do that if you're flying too slowly, like around 300 kph. You probably want to be going at least 500 kph in an attack run or faster.

It depends largely on the situation. Both CCIP and CCRP are available, though due to the size of the piper CCRP tends to be less accurate than CCIP. A good technique is to roll in at something like 7,000m altitude and release at anything between 2-4,000m. The steeper the dive the more accurate the release tends to be, though you do have to be careful about your speed building up in the dive.

 

Because all the A2G weapons on the Su-27 are unguided I really wouldn't recommend taking on any targets that have any AA defences more advanced than a ZSU-23-4 and even then, maybe.

 

There is another highly unusual bombing technique for defended targets which involves approaching the target at Vmax (usually around 1,200 Km/h TAS) at around 1,000m altitude, releasing in CCRP mode then doing a max-G turn to avoid overflying the target. Supersonic bombing like this is amusing but tends to be rather inaccurate and uses up an awful lot of fuel.

 

Happily as of a recent patch the Su-27 will release bombs (including RBK cluster units) in matched pairs so you won't have any asymmetric trim issues. 500 - 600 Km/h in a 40 - 50 degree dive usually produces the best results for bombs.

Thanks for the tips guys!

I was having the same wobbling problems at first and found it very difficult to hit anything on the ground or to keep a missile locked. Tuning the axis on the joystick fixed it for me. I have an extreme 3d pro and it has a bit of play when centered so I set some dead space in the center.

Good point. I'd also recommend using 15-20 curvature for both pitch & roll so that you can accurately place the target piper.

 

One more thing to remember - the Russian RBK cluster bombs don't have a set function altitude, they seem to operate purely on a timer, so increasing release altitude will increase the area of coverage and vice-versa.

 

Pages 80 - 88 of the Su-27 flight manual gives good descriptions of the various weapons available and the types of target they can be usefully employed against. Something to bear in mind though is that in DCS fragmentation from warheads is not modelled - only blast which decreases from the point of explosion as ~ 1/r^3. Thus blast frag warheads won't be anywhere near as effective against targets like troops in the open as they ought to be.
