Description
Real Missiles
Real Missiles configures ECM resistance, speeds, and accuracy of missiles—to reflect those systems real world combat performance.

Some missiles, like X-23 (SACLOS), X-58 (Anti-Radiation), and AGM-84 (Anti-Radiation) were previously unjammable / spoofable, which is not reflective of real world data. Many missiles didn't use their real-world velocity.

Speed & Velocity corrections
Many missiles have received revisions and corrections for the max velocity.

Examples:

RIM-66C/B/A all used 2000 knots velocity. Velocities were changed to 2300, 1650, 1650 respectively.
S-300F had 3,910 knots velocity. Real velocity is somewhere from 4,200-4,500 knots (Mach 6.3-6.6)
RIM-67A/B had 2000 knots velocity. Real velocity is ~1,560 knots and ~2,300 knots respectively.
RIM-7 used 2300 knots, whereas real max speed is about ~2,645 knots. (Mach 4)
M-4 Osa used 980 knots, real speed is 1,986 knots. (Mach 2.4)

+ Many more.

ECM Explanation & Examples
Spoofing and jamming are determined by the strength of the emitter and its distance, as well as the missile's resistance. The spoofing and jamming resistance of missiles is subtracted from the base chance to determine the current chance of spoofing / jamming to occur. This means for example: If Current Spoofing chance = 25%—and Missile spoofing resistance is 0.35, the missile has a -10% to be spoofed. (which mean it is impossible.) If base chance is 50% (considerably high) the chance of spoofing is still only 15%.
This means that spoofing of most missiles almost never happens, which is unrealistic for cold war technologies.

Testing & Methodology
3 Ticonderoga-class Missile Cruisers (non-VLS) in a group are using AEGIS defence system. 16 P-500 Bazalt (1300 Knots, Supersonic) and 8 P-700 Granit (970 Knots, Supersonic, Spoofing Capability) Missiles are launched in a saturation attack from one direction toward the grouping.
In the first test, the RIM-66C had a Spoofing resistance of 0.35;
In the Second test, it was reduced to 0.15.
The Results are as follows:

The second test with the modification shows how changing the Spoofing Resistance of missiles affects the average interception rate, as well as the number of missiles spoofed. Now that we have an idea of behaviour, we can accurately adjust values based upon verifiable real-world performance.

Other tests:
Another test was conducted, where a saturation attack of 16 sub-sonic AGM-84 Harpoons were launched against a single Orlan-Class (Kirov-Class) Cruiser. 5/16 Missiles were spoofed. The AGM-84 had the standard-value of 0.25 Spoofing Resistance.

Testing Conclusion:
From these tests we can deduce the following about behaviour of resistance values:
Resistance Value
Description / Realistic Outcome
0.00 – 0.10
Practically no resistance. Easily spoofed/jammed. Older tech or basic guidance.
0.15 – 0.25
Low to moderate resistance. Can be spoofed under coordinated ECM.
0.30 – 0.35
Solid resistance. Only some missiles get spoofed. Decent ECM resilience.
0.40 – 0.50
High resistance. Spoofing or jamming is rare. Advanced ECCM or multi-mode seekers.
0.55 – 0.70
Very high resistance. Spoofing/jamming unlikely except under ideal enemy conditions.
0.75 – 1.00
Practically unspoofable or unjammable. Likely theoretical, Wire-guided, or uses modern ECCM systems.

Appendix
- More corrections will be made for more systems as I gather more data over time.

@mr_derpo If NTU modifies characteristics or behaviours of missiles, then it likely isn't compatible.
mr_derpo 10 Jun @ 9:16pm 
Is this compatible with ntu or are ntu weapons just not affected by these changes
Acey 10 Jun @ 3:54pm 
Ok just wondering thanks

@Acey no, Air-to-Air missiles aren't modified.
Acey 10 Jun @ 12:07am 
Did you change the accuracy of the AIM 7Es?
Schizo  [author] 9 Jun @ 11:28am 
@Kyazite Put after anything which may modify Missiles. Otherwise, it doesn't matter.

Where to put in load order?

@nuclearstonk You're right, max speed should be ~2,300 knots for the RIM-67B. (Mach 3.5)
nuclearstonk 8 Jun @ 1:50pm 
where did you get the data for RIM-67s speed? it's significantly slower than RIM-66 despite having a booster lol
Schizo  [author] 8 Jun @ 4:59am 
@Dart_Kotinator Yes, Missile Speeds and ranges will also be revised in the next update.
