ANKARA, Turkey — The Turkish Navy is considering the purchase of long-range patrol aircraft to add to its fleet of CN-235 and ATR72s, navy and procurement officials said.

"The requirement comes in line with the government's foreign policy priorities," explained one procurement official.

Navy officials say the planned aircraft should be able to fly 1,000 to 1,200 nautical miles away from their main base in Turkey and fly 12 to 15 hours.

"Our current fleet may not respond to our future roles," said one Navy official. "The new patrol aircraft should ideally have anti-submarine and anti-surface warfare roles."

Naval industry sources say the Turkish description of the requirement would probably point to the Boeing P-8 Poseidon (formerly the Multimission Maritime Aircraft or MMA). The P-8 Poseidon was developed for the US Navy by Boeing Defense, Space & Security, modified from the 737-800ERX.

The P-8 also conducts shipping interdiction, along with an electronic signals intelligence role which involves carrying torpedoes, depth charges, SLAM-ER missiles, Harpoon anti-ship missiles, and other weapons. It is able to drop and monitor sonobuoys. The aircraft is designed to operate in conjunction with the Northrop Grumman MQ-4C Triton Broad Area Maritime Surveillance unmanned aerial vehicle.

Procurement officials say they hope to issue a request for information for the planned acquisition soon.

"We are hoping to see a competitive contest," one official said.

But industry sources say the description of the acquisition narrows options.

"There will not be too many bidders, judging from the description of the requirement," said one source.
