I used to only understand Sparrow as an old aerial aunched target missile, but it seems that the modern Sparrow is a kind of Marv and can travel much further than its booster discard point.
Since the boosters were found 100 km from the Iranian border, it is almost certain that the three missiles reached Iranian territory.
The Iranian government's silence on the matter could be due to the following reasons:
- The Sparrow warheads got lost somewhere and Iran, unable to detect them, has not found the fallen warheads.
- The warheads fell on a facility, causing damage, and Iran is keeping quiet to save face or due to some deal made.
Had they successfully intercepted the missiles, they would have boasted about it. This incident, upon calm consideration, seems to be a warning about the vulnerability of Iran's air defense network.
