Russian experts are studying why the two state-of-the-art Russian-built radar systems in Syria did not detect the Israeli jets entering Syrian territory.

Iran reportedly has asked the same question, since it is buying the same systems and might have paid for the Syrian acquisitions.

Syria’s most recent confirmed procurement was of the Tor-M1 (SA-15 Gauntlet) short-range mobile SAM system. It uses vehicle-mounted target-acquisition and target-tracking radars. It is not known whether any of the Tor systems were deployed in the point-defense role at the target site struck by Israeli aircraft. If, however, the target was as “high-value” as the Israeli raid would suggest, then Tor systems could well have been deployed.

Iran bought 29 of the Tor launchers from Russia for $750 million to guard its nuclear sites, and they were delivered in January, according to Agence France-Presse and ITAR-TASS. According to the Syrian press, they were tested in February. Syria has also upgraded some of its aging S-125s (SA-3 Goa) to the Pechora-2A standard. This upgrade swaps out obsolete analog components for digital.

According to various reports, Iran’s mullahs are extremely fearful that a joint US-Israeli attack could wipe out their nuclear research facilities and the entire Iranian military in a matter of hours.
