Indonesia has finalised a $1.14bn deal with Russia for 11 Sukhoi Su-35S multi-role fighter jets, of which two units will be delivered in August.
Six additional units will be delivered 18 months after the deal becomes effective, while three units will be delivered five months later.
This deal will enable the Asian country to replace its ageing F-5 Tiger planes, which have been operational since the 1980s.
Su-35 is is a multi-role fourth-generation supersonic fighter jet that comes with a phased array radar.
The manoeuvrable thrust-vectoring aircraft has a top speed of around 2,500km, with a combat radius of around 1,600km. It also has a 30mm gun with 12 hardpoints.
The negotiations between the two countries commenced in 2015, but the process had been delayed due to countertrade deals.
Indonesia needs countertrade in some commodities such as palm oil and rubber to negate at least 35% of the costs of these fighter jets.
Russia has made a commitment to purchase certain commodities that would help Indonesia to negate around 50% of the deal value.
With this contract, Indonesia has become the second customer for the fourth-generation fighter jet after China, which placed a $2.5bn order for 24 jets three years ago, reported Ainonline.com.
China received four jets in 2016 and ten in 2017. The remaining ten will be delivered this year.
The Su-35S contract is seen as the first in a lineup of war equipment deals with Russia. The deal is reportedly a shipbuilding programme, details of which are yet to be divulged.
