Spotting Types

• hexes seen=range/(km/hex) round up
• km/hex SR2020 = 16
• spotting loss = str/(hexes seen+1)
• first hex str=str
• next hex str = previous hex str - spotting loss

Formula Explanations

So what does all this mean? Spotting is done in a fashion similar to supply, it has a source and weakens over distance. each additional hex away, the strength is weaker. If the spot strength at a certain distance is more than the stealth of units at that location, the units are seen. If not, they are not. Here's an example of how to calculate this manually;

Our targets will be an F-15K (stealth 30) and an F-22a (stealth 120)

For this example our spotting source will be a Tu-142M. It carries two spot types;

• type 101
  • Range 101km
  • Strength 130
• type 540
  • Range 40km
  • Strength 302

Based on the above stats we know that both aircraft types can be spotted, we just need to determine when and where. If the aircraft are all in the same hex, the strength of the spotting would be 130/302 respectively and more than enough to see both aircraft. But even next hex, those values would be going down. Based on the above notes we can determine what the values would be;

Example: Type 101

• hexes seen=range/(km/hex) round up
• km/hex SR2020 = 16
  • so in this case 101/16=6.3 so 7 is our "max hex range". Strength at the 8th hex will be officially zero.
• spotting loss = str/(hexes seen+1)
  • so here we have 130/(7+1)=16.25
• first hex str=str
  • In this case, in it's own hex, the unit sees anything stealth 130 or less
• next hex str = previous hex str - spotting loss
  • This means that at hex 0, the unit spots @ 130, but at hex 1 (Zone of Control) it spots @ 130-16.25=113.75, round up to 114. Here are the rest of the values for a type 101;

Hex distance	0 hexes	1 hex	2 hexes	3 hexes	4 hexes	5 hexes	6 hexes	7 hexes	8 hexes
Strength	130	113.75	97.5	81.25	65	48.75	32.5	16.25	0

So a Type 101 can't see an F-22 till it's on top of it (str 130 @0 vs. 120) but will see an F-15 from 6 hexes away (str 16.25 @6 vs. 30)

Example: Type 540

If we try the same thing with the type 540 we get the following values

• hexes seen=range/(km/hex) round up
• km/hex SR2020 = 16
  • So 40/16=2.5 round up to 3.
• spotting loss = str/(hexes seen+1)
  • 302/(3+1)=13.33
• first hex str=str
• next hex str = previous hex str - spotting loss
  • This means that at hex 0, the unit spots @ 130, but at hex 1 (Zone of Control) it spots @ 130-16.25=113.75,

Hex distance	0 hexes	1 hex	2 hexes	3 hexes	4 hexes	5 hexes	6 hexes	7 hexes	8 hexes
Strength	302	288.67	275.33	262	0	0	0	0	0

Meaning a Type 540 can see an F-22 or an F-15 up to 3 hexes away but sees nothing beyond that range.

This assumes that no factors are affecting the stealth rating of the aircraft such as combat or RoE.
