The IndoPacific Defense Forum reports on the construction of a training facility for the Indonesian Coast Guard, known as Bakamla.
“The training center is a collaborative effort by Bakamla, which was established in 2014, the U.S. Coast Guard; the U.S. State Department’s Bureau of International Narcotics and Law Enforcement Affairs and the U.S. Department of Defense.”
Batam lies just 32 kilometers south of Singapore, across the Straits of Malacca, perhaps the busiest waterway in the world.
Incidentally, Indonesia has a second agency that seems to have overlapping, coast guard style duties.

Actually I think Singapore is more likely. Navy LCS are already using it. But good to have friends on the other side of the Strait.
