Turkish Prime Minister Recep Tayyip Erdogan announced Friday that his government and US helicopter manufacturer Sikorsky Aircraft had signed a long-dormant contract to co-produce an initial batch of 109 utility helicopters.

“We signed the $3.5 billion agreement today,” Erdogan said in televised remarks during a ceremony for the delivery by Boeing of Turkey’s first airborne early warning and control aircraft. “This [Sikorsky deal] was an important signing ceremony for us.”

In May, Turkey’s procurement office made an unusual announcement: Turkey “had come very close to signing a $3.5 billion contract with Sikorsky Aircraft for the co-production of scores of utility helicopters.” But penning the deal had since been delayed as top Turkish procurement management accused “US corporate and other bureaucracy” for factors that caused delays.
