According to Bangkok Post the Thai air force is seeking approval to buy six Gripen jet fighters in addition to the six already ordered, and hopes the submission will be approved by the cabinet today.
The air force had hoped to decommission its 12 US-made F-5 E/F fighters, in operation at the Surat Thani-based Wing 7 for 30 years, once it took commission of 12 new Gripen 39 C/D fighter jets.
