Turkey’s defense procurement authorities have pushed the button to launch an international competition for the acquisition of a batch of 52 basic trainer aircrafts, otherwise known as “screeners.” The Under secretariat for Defense Industries (SSM) has issued a Request for Proposals (RfP) for the contract that foresees the off-the-shelf purchase of a small fleet of screeners. The screeners will replace a fleet of ageing SF 260s used in the Turkish Air Force for preliminary training Defense industry sources said the screener contract could go up to approximately $75 million.
