Indonesian Military buildup

Indonesia to Buy Military Aircraft and Submarines
Indonesia is in talks with the United States to buy Lockheed Martin C-130 Hercules transport planes and might be in a position to buy fighter jets and submarines in 2-3 years.
The country aims to raise its defence spending to 1.2 percent of
gross domestic product within five years, from 0.68 percent or
33.6 trillion rupiah ($3.3 billion) now.
Defence spending of the world's fourth-most populous nation, was far below neighbouring countries such as Singapore, Australia and Malaysia.
China is building up its military and Australia said this month
it plans a $72 billion defense upgrade over the next 20 years,
including new submarines, leading to fears among some experts of
an arms race in Asia as countries look to maintain control over
trade routes and borders.
Since Singapore is buying F-15 fighter jets, Indonesia was
matching that move by buying Russian Sukhoi fighters.
