[NO BUG] SA-2 Pure Pursuit Resulting in Miss

[Xoho]

The SA-2 currently appears to only aim for pure pursuit and does not pull nearly enough lead to hit even a B-52H at 36,000ft flying with no ECM, chaff, or maneuvering.

SA-2 Guidance Issues #001.trk

[AeriaGloria]

I have a sneaking suspicion this is how the actual missile works, can’t wait for someone who knows to answer

[Xoho]

@AeriaGloria, I wouldn't think so, as it essentially means that it will never hit a target unless it's flying directly at (not just over), or away from the launcher. Considering how successful they were in certain conflicts, that would be pretty hard to imagine being the case.

[AeriaGloria]

True. Its pretty useless in the MiG-19 campaign, I thought it was maybe scripting but maybe not. A lot of fun to watch telephone poles fly by you with the new sonic booms!

It's been like this for over a year, so “currently” is a bit of an understatement. :D

The Sa2 has several different guidance modes, all of which are fundamentally under the umbrella of command guidance.

 

 

 

 

 

In short command guidance is where a tracking radar locks onto and tracks a target. It then calculates an intercept point. Once the missile is launched it is connected to the central computer via a missile uplink. In the SA2 this uplink is in the but of the main body. Additionally this antenna is blinded for the duration of the boost stage and as such it should not do any maneuvering at all during this time. Once the boost motor falls away and the uplink is established the computer will track where the missile is and where the target is and compute sterring corrections which will then be sent up to the missile. The missile itself has no ability to detect the target. This is why missile uplink jammers were so effective in vietnam, once the uplink is servered the missile goes balistic. Additionally there was the unintended sidefect of this often caused the missile to explode!

 

 

Half Lead:

 

 

 

 

 

Three Point:

 

 

This is basically what we have now, it a pure pursuit fly out and is really only used against jamming targets or if ranging data is unreliable.

 

 

 

Other Special Modes:

 

 

yes... this is a ground attack mode :P

 

 

 

 

The Necessity of Proximity Fuzes:

 

A BIG problem here is the lack of the proxy fuze code. Missiles like the SA2 often lacked the precision and hence ability to get direct hits unless it was a very large bomber like target. This is why missiles like the sa2 and sa3 had very large warheads and proxy fuze ranges. 20-35m on the sa2. So even with the above guidance fixes we would relly need to add the proxy fuze code:

 

		
fuze_proximity = {
ignore_inp_armed	= 1,
arm_delay			= 3,
radius			= 35,
			},

 

do note though below 100m ground clutter effectively rendered the proxy fuze unusable for the in game missile type.

Checked with the team, not a bug, thanks for the report guys.
