Despite the return of Indira Gandhi to power in 1980, the relations between the two countries continued to improve gradually, although India did not support the United States in its role in the Soviet invasion and occupation of Afghanistan. The Reagan Administration led by US President Ronald Reagan provided limited assistance to India. India sounded out Washington on the purchase of a range of US defence technology, including F-5 aircraft, super computers, night vision goggles and radars. In 1984 Washington approved the supply of selected technology to India including gas turbines for naval frigates and engines for prototypes for India's light combat aircraft. There were also unpublicised transfers of technology, including the engagement of a US company, Continental Electronics, to design and build a new VLF communications station at Tirunelveli in Tamil Nadu, which was commissioned in the late 1980s.
