The United States and India have been building a strategic partnership over the past few years, particularly in the areas of defense and security. In recent years, the U.S. has been trying to increase its defense sales to India and woo it away from its traditional military supplier, Russia.

The F-35 fighter jet and the B-1B bomber are two advanced U.S. military aircraft that have been offered to India as part of this effort. These aircraft are considered some of the most advanced and sophisticated military equipment in the world and could provide India with a significant boost in its military capabilities.

India has shown interest in the F-35, but has not yet committed to purchasing the aircraft due to concerns about its high cost and technology transfer issues. India has also been seeking to diversify its military supplier base and reduce its dependence on any one country.

The U.S. has been actively courting India with military equipment and technology transfers, as part of its broader strategy to strengthen ties with India and counter China's growing influence in the region. The U.S. and India have signed several defense agreements in recent years, and the U.S. has become one of India's top defense suppliers, with billions of dollars in defense contracts signed between the two countries.

Overall, the U.S. is looking to deepen its strategic partnership with India, and military equipment and technology transfers are just one aspect of this effort. However, India's decisions on defense procurement will ultimately be driven by its own strategic priorities and needs.
