I just tried 4 times to hit a lone Udaloy...got nothing.
In one attempt, one missile did get through, but then as the missile was inside Rmin for the SA-N-9, it suddenly pulled up and dissapeared. Is this what a spoofed SLAM will do? Another missile that I know was spoofed was seaskimming rather than climbing to chase the chaff, but was shot down before Rmin so I couldn't repeat it.
It seems like the acquisition range of the seeker is about 8nm, which is about the same range the SA-N-9 is fired. (Guns engagement begins around 13nm) At least against the Udaloy, the SLAM-ER doesn't seem to be getting any benefit from its flight profile. The salvo must pass through the entire engagement range of the Gauntlet. Since the detction range for the Udaloy is at least 13nm and the seeker range is only 8nm, and the missile won't drop to seaskimming mode unless it has acquired a target, effectiveness does not change whether the enable point is set right at 8nm or if it is further out. Although, to be totally fair, the SA-N-9 (SA-15) is pretty badass, probably at least as good as the ESSM. (although the near 100% hit rate we're seeing in DW is probably a little too badass).
Trying against a Sovremennyy, detection/guns engagement took place at 15nm. The SA-N-7 Gadfly (SA-13) engaged around 8-9nm and was about 40% effective, which is in line with Globalsecurity estimates. But the Sov's CIWS picked up most of the slack. Between two tests, one missile got through (and caused a CTD). In both, the division of labor was about half and half between the Gadfly and CIWS. (In comparrison, an AGM-65 run against the Sovremennyy scored multiple hits for 76% damage.)
Against an AI OHP, the OHP engaged with, sigh, single SM-2 shots (should be 2 at a time!) from 15nm out. It shot down 4 with SM-2s, 2 with the CIWS, and spoofed the other with chaff.
Against a Krivak, it detected the missiles and engaged with guns at about 12 nm, shot down 1 with the SA-N-4 (SA-8), shot down 4 with its CIWS and spoofed the other two.
So I shot 56 SLAM-ERs today and got 1 hit out of it.
It seems that the SLAM-ER is just as ineffective as the Harpoon is, with its improved flight profile having little to no effect. In any case, the overwhelming effectiveness of the Gauntlet and CIWS systems is more than a match for this or any other subsonic missile.
