The Russian Aerospace Forces will receive the first Yak-152 primary trainer aircraft for trials by the end of the spring and plan to sign the contract with the manufacturer afterward, the forces' deputy commander said Wednesday.

According to the corporation, Yak-152 can be used for practicing navigation basics, various piloting techniques, from basic to aerobatic pilotage, emergency piloting and many other aspects of pilots' training.

"Yak-152 should be sent to [State Flight Tests Center] for state trials by the beginning of the summer this year," Lt. Gen. Andrey Yudin said.

Yudin said that the Russian Defense Ministry would sign a contract with the manufacturer after the trials, but he would not specify how many it was planning to buy.

The Irkut corporation began manufacturing these aircraft in 2006.
