HARM TOO and SP mode

[Fuelburner]

I was wondering when to use which mode. What are the differences und advantages of the respective modes.

 

Thx

With TOO more you can filter out types of radar and kinda see where it is in relation to your aircraft

[Tom Kazansky]

the SP mode offers a quick response solution if there pops up a radar threat to you or the aircraft you want to protect immediately. Without selecting source and hand off.

[Tholozor]

TOO mode also provides line-of-sight indication in the HUD, so you can use it as a poor-man's spotting tool to find the location of emitters.

[Harker]

SP (Self-Protect) mode should lock to the higher threat emitter and the pilot just needs to fire. You can manually cycle emitters with the "HARM Sequence/RAID/FLIR FOV" button on the throttle and pressing RESET on the HARM page will revert back to the highest threat emitter.

 

TOO (Target Of Opportunity) mode essentially shows you what the seeker of the missile is seeing. It allows for a much more refined selection of targets and allows you to limit the selectable targets based on a range of filters. You can, for example, distinguish between search and tracking radars this way, or between friendly and hostile emitters, second generation SAMs, naval systems etc. The HARM seeker also receives data from the RWR, so you see the combined picture.

 

Both SP and TOO mode are direct attack modes, meaning that the missile has no range information on the emitter and will fly directly towards it. PB (pre-briefed) mode (not available yet) will enable range to be taken into account for longer range strikes at known targets.

 

Pullback mode (not available yet) is a sub-mode of SP, where upon detecting either a lock or a launch ( I'm not sure), from a SAM, the system will switch to HARM SP mode regardless of what you were doing and request consent (pickle button) to launch a HARM at that threat. You can disable Pullback mode via the HARM SP page (it's disabled by default right now, in the sim).

SP Mode provides 360 degree "over-the-shoulder" capability to the HARM, but it is short-ranged. It literally is designed for self-protection against pop-up threats.

 

In DCS the HARM's ability to engage targets behind you in SP Mode is iffy as the missile can end up flying straight up or straight down instead of looping over the shoulder to hit targets. But I suppose it's better than nothing.

Thanks a lot for this fantastic explication, really appreciate :thumbup:

Happy to help! I forgot to mention that in TOO more, you cycle targets with the HARM Sequence button and then lock them with the Cage/Uncage button. You need to set priority to the HARM page to do that.

Happy flying!

Anybody actually have SP mode pick the highest threat though? It always seems to target some far off search radar for me when I’m being engaged by an sa15

Tried tonight and realized that it'll pick the highest threat initially, but it won't update by itself as the situation changes. You need to press RESET on the HARM page and then it'll default to the current highest threat.

I think it should be able to update by itself though, otherwise Pullback mode would be useless, since its purpose is to immediately attack the highest threat.

Thanks. I thought something was going on. Good to know about a work around too. I didn’t experiment, just started using TOO mode instead
