Boeing [BA] recently said that India has signed an agreement with the U.S. government to acquire 10 Boeing C-17 Globemaster III airlifters, making India the C-17’s largest international customer.

Boeing will support India’s C-17 fleet through the C-17 Globemaster III Sustainment Partnership, a multinational Performance-Based Logistics program. The GSP “virtual fleet” arrangement ensures mission readiness by providing all C-17 customers access to an extensive support network for worldwide parts availability when purchasing materials.

According to the agreement, India will take delivery of its C-17s in 2013 and 2014.
