According to information published by India Today on April 25, 2023, a proposal is under consideration by the government and is expected to be cleared soon for the acquisition of US Harpoon and Russian Kalibr missiles.
The Harpoon missile and the Kalibr missile have similarities in their capabilities and differences in their specifications. Here is a comparison of the two missiles:
Mass: The Harpoon missile has a mass of 1,523 lb (691 kg), including the booster, while the Kalibr missile’s mass varies based on the variant, ranging from 1,300 kg to 2,300 kg.
Length: The Harpoon missile is 12.6 ft (3.8 m) long when air-launched and 15 ft (4.6 m) long when surface- and submarine-launched. The length of the Kalibr missile varies based on the variant, ranging from 6.2 m to 8.9 m.
Diameter: The diameter of the Harpoon missile is 13.5 in (34 cm), while the diameter of the Kalibr missile is 0.533 m.
Warhead: The Harpoon missile’s warhead weighs 488 pounds (221 kg), while the Kalibr missile’s warhead varies based on the variant, ranging from 400-500 kg HE or thermonuclear.
Engine: The Harpoon missile is equipped with a Teledyne CAE J402 turbojet/solid propellant booster for surface and submarine launch, providing over 600 lbf (2,700 N) of thrust. The Kalibr missile uses a multi-stage solid-fuel rocket engine, turbojet engine for some variants, and a solid fuel rocket engine for others.
Operational range: The Harpoon missile has an operational range of 75 nmi (139 km) when ship-launched (Block I & Block IC) and 120 nmi (220 km) when air-launched (Block IC). The Kalibr missile’s operational range varies based on the variant, ranging from 50 km to 4,500 km.
