The two aircraft would be procured under the U.S. Foreign Military Sales program as part of a package deal worth about $61 million.
"This proposed sale would contribute to U.S. security and foreign policy goals by building the Philippines' maritime domain security capacity and deepening our overall strategic partnership with the Philippines," the agency said.
"The government of the Philippines desires these additional C-130s to bolster its lift capabilities, which are essential for providing humanitarian assistance and disaster relief.
"The Philippines will use this increased lift capability to improve the mobility and resupply of its forces and for the provision of humanitarian assistance in the Philippines and the wider region, thereby reducing the potential level of U.S. assistance requested/needed for these purposes."
The sales package requested is for two Hercules aircraft, 10 T56-16 engines, logistical sustainment and support for a period of three years, modification equipment and labor costs, spare and repair parts, support equipment, publications and technical documentation, aircraft ferry support and personnel training and training equipment.
The agency said that contractor requirements were still being researched.
The U.S. State Department has already approved the sale.
