India signed a deal with the United States of America (USA) to supply MH-60R helicopters to the Indian Navy. The MH-60R helicopters are advanced maritime helicopters that are specifically designed for anti-submarine warfare, search and rescue missions, and intelligence gathering. India`s decision to sign a deal with the USA for these helicopters highlights the growing strategic partnership between the two countries. The deal with the USA allows India to enhance its naval capabilities and strengthen its defense capabilities in the Indian Ocean region. The MH-60R helicopters will significantly enhance the Indian Navy`s ability to detect and counter enemy submarines, improving India`s maritime security. This deal also demonstrates the increasing defense cooperation between India and the USA, which includes various military exercises, joint training programs, and defense technology transfers. It is important to note that while options such as Israel, France, and Russia are countries with which India maintains defense ties, the correct answer in this case is the USA.
