The equipment has now been delivered to the Turkish Aerospace Industries (TAI) facility in Ankara, the Turkish news website Today’s Zaman reported on Sunday.

Israel’s Defense Ministry has refused to comment concerning the deal.

Turkey acquired four Boeing 737 passenger aircraft from Boeing, which were converted into AWACS alert and intelligence aircraft worth $200 million.  The Turkish newspaper Zaman reported that Israel transferred two systems to Turkey before the relations between both countries were strained in 2010. Israel recently transferred the remaining systems to the Turkish Aerospace Industry (TAI), and these will be installed soon.

According to a defense source quoted by Reuters, Boeing intervened in the relations between the countries and brought Elta to meet the terms of the agreement and complete the delivery.

On May 31, 2010 the Israeli Defense Forces (IDF) boarded the Turkish-flagged Mavi Marmara, the largest ship in a flotilla aimed at breaking Israel’s siege on Gaza in May 2010, leaving nine pro-Palestinian activists dead.

Turkey, which in the past was very friendly with Israel, has elected a government with an increasingly worsening stance toward Israel, as well as increasing support for Palestinians and pro-Palestinian activists.

Turkey demanded a formal apology but Israel refused to make a formal apology and pay conpensation to families of the dead. As a result, expelled Jerusalem’s ambassador from Ankara. Diplomatic ties were severely downgraded, and have remained impaired ever since.
