Number six of the six C-130J Super Hercules ordered by India, under the U.S. Foreign Military Sales program, departed Marietta, Ga. on December 15, 2011. This aircraft, like its five predecessors, was delivered ahead of schedule and under budget.

These C-130J’s were ordered post 26/11 and are meant to be used by India’s elite special and counter-terrorism forces. Hence the ability to operate in complete darkness.
