One of the technologies that the USA is said to have offered to India is
One such technology is the magnetic catapult- makes it possible for larger planes to take off from smaller ships. The Electromagnetic Aircraft Launch System (EMALS) is a system under development by the United States Navy. The main advantage is that this system allows for a more graded acceleration, inducing less stress on the aircraft's airframe. Other advantages include lower system weight, lower cost, and decreased maintenance requirements. It also will provide the ability to launch aircraft that are both heavier or lighter than the conventional system can accommodate. In addition the system has limited requirements for fresh water, reducing the need for energy-intensive desalination.
