giantsquid -> RE: SAM accuracy when intercepting missiles (3/22/2017 11:56:58 PM)

On this topic, here is an interesing article about Brahmos/supersonic missiles attack against modern ships
https://defencyclopedia.com/2014/12/27/explained-how-the-us-navy-can-shoot-down-the-deadly-brahmos-missile/
I tested Brahmos against an alerted USN Burke DDG with ESSM in CMANO.
8 Brahmos missiles at 30 ft at 1450 knots
Missiles detected at 16 nm by SPY1D
First SAM launch t+10 sec
All easily intercepted by ESSM, some redirecting weapons
Weapon: RIM-162A ESSM #12 is attacking PJ-10 Brahmos #4 with a base PH of 90%. Target speed modifier: -10%. Target signature modifier: -10%. Final PH: 70%. Result: 57 – HIT
9-10 Brahmos seems to be the saturation limit. With 16 weapons I always scored hits on Burke
Impact at T+45sec. Missiles were fired all together in automatic mode, approaching from the same direction in “train” formation. Probably you can obtain better result plotting the course and making 2x4 of them arrive at the same moment form different directions.
Another try vs Chinese Type-52D Luyang III, always with 8 Brahmos
Always detected at about 16 NM and them shot down by HQ-9B, same as before
Weapon: HQ-9B #40 is attacking PJ-10 Brahmos #31 with a base PH of 80%. Target signature modifier: -10%. Final PH: 70%. Result: 37 – HIT
I tried with 16 missile and the Chinese ship was hit. I noticed the terminal maneuver, great work by devs! I’m always impressed with the level of detail of the simulation. I think it only applies when Brahmos locks on target I the last few NM. Below some interception with terminal maneuvers.
13:00:17 - Gun (30mm China H/PJ-12 [Type 730, 240 rnds]) is attacking PJ-10 Brahmos #32 with a base-Ph of 70%. Base-Ph adjusted for distance: 70%. Target speed modifier: -30%. Target size modifier: -3%. Target is missile with zig-zag terminal manouver - hit probability reduced by 33%. Final Ph: 24%. Result: 17 - HIT
13:00:14 - Weapon: HQ-9B #58 is attacking PJ-10 Brahmos #32 with a base PH of 80%. Target signature modifier: -10%. Target is missile with zig-zag terminal manouver - hit probability reduced by 33%. Final PH: 46%. Result: 59 – MISS
Maybe the Target speed modifier: -10% & Target signature modifier: -10% were too optimistic for such a small, sea skimming, ultra fast missiles? According to the article the Pk should be more around 40-50%. What do you think?
