 In 1982, India signed a contract to purchase several Mk42B Sea Kings, an upgraded variant to perform dual-purpose: anti-shipping and anti-submarine missions, following a competition for the order against the Aérospatiale Super Puma. These helicopters would operate from the Godavari-class frigates as well as replace the existing Sea Kings. A team of Indian engineers was sent to Britain to help develop the Mk42B's avionics, especially the onboard software. Changes from the older Sea Kings included a brand new avionics suite, the use of composite materials throughout the fuselage and in the rotor blades, as well as the integration of the Sea Eagle missile, which had been procured from Britain in 1983. Between 1988 and 1992, a total of 20 Mk42B Sea Kings were delivered to the Indian Navy.
