Iranian investigators are blaming a misaligned missile battery and miscommunication between soldiers and their commanders for the Revolutionary Guard shooting down a Ukrainian jetliner in January, killing 176 people.

The report released late Saturday by Iran's Civil Aviation Organization comes months after the January 8 crash near Tehran, which authorities for days denied having hand in.

The shootdown happened the same night Iran launched a ballistic missile attack targeting US soldiers in Iraq, its response to the American drone strike that killed Guard Gen. Qasem Soleimani in Baghdad.

At the time Iranian troops were bracing for a US counterstrike and appear to have mistaken the plane for a missile.

Report details series of moments

The report detailed a series of moments where the shoot down of Ukraine International Airlines Flight 752 could have been avoided.

The report said the surface-to-air missile battery that targeted the Boeing 737-800 had been relocated and was not properly reoriented.

Those manning the missile battery could not communicate with their command centre, they misidentified the civilian flight as a threat and opened fire twice without getting approval from ranking officials, the report said.

“If each had not arisen, the aircraft would not have been targeted,” the report said.

Western intelligence officials and analysts believe Iran shot down the aircraft with a Russian-made Tor system, known to NATO as the SA-15. 

In 2017, Iran took the delivery of 29 Tor M1 units from Russia under a contract worth an estimated $700 million. 

The system is mounted on a tracked vehicle and carries a radar and a pack of eight missiles.

The report notes that the Ukrainian flight had done nothing out of the ordinary up until the missile launch, with its transponder and other data being broadcast.

"At the time of firing the first missile, the aircraft was flying at a normal altitude and trajectory," the report said.
