Thailand has received three Sikorsky S-92A VIP transport helicopters, as well as its first batch of Mil Mi-17 multi-role utility helicopters.
The S-92As will be operated by the Royal Thai Air Force for use by the nation's king and queen and other members of the royal family, the service says.
Two of the S-92As will perform VIP transport missions in a 12-seat configuration, while the third will be equipped for emergency medical treatment - Thailand's 83-year-old king is reported to be in poor health.
Thailand's army also recently took delivery of the first three of six Russian-made Mi-17s, according to Thai media reports. Bangkok ordered the utility aircraft in 2008.
