Given it was a head-on shot, that would require the R-40T to be all-aspect...
Who said it was a head-on shot?
EDIT: On further look, there were more modern R-40T variants with all-aspect seekers, so it is possible, if Iraq had those improved missiles available.
Actually, the reason for existence of IR-homing variants of specific Soviet missiles (like R-40T), and for the existence of SAR-homing variants was a combination of factors like early Russian pulse Doppler radars being foremost able of detecting and tracking only targets approaching them, but not the targets distancing themselves from the radar, or flying perpendicular to it; correspondingly,
- R-40R was to be used for attacks from the forward hemisphere (supported by radar, of course), and
- R-40T was to be used for attacks from the rear hemisphere (supported by the IRST).
The missile that hit Speicher's F/A-18C was an R-40RD - an export-, but still improved variant of the original R-40R. And, it approached and hit from the left rear side (approx 7-8 o'clock as seen from Speicher's position).
The reason Speicher didn't know he was under attack is that his RHAWs failed already before take-off. He decided to continue the mission, though.
...of course, this all was 'supported' by the AWACS failing to provide permission to fire to Speicher's formation leader, who had a firm lock-on on the Foxbat while this was still approaching from the north, and then the failure of the AWACS to track the Foxbat as this passed by, made a turn around the USN's formation and re-attcked.
