The missiles are offered directly by the US Government to India through the Foreign Military Sales (FMS) route, he said.
The IAF is in final stages of the contract and is soon expected to award the contract.
Barnard said Raytheon was also planning to offer the missiles for being equipped on India's indigenous helicopters, which include the HAL developed Light Combat Helicopter and Advanced Light Helicopter.
"We are yet to get clearance from the US Government for this but we have plans to offer the Stinger for being equipped on Indian helicopters," he said.
Raytheon India Head William Blair said the company has developed a vehicle-launched version of the Javelin anti-tank guided missile and is in discussion with local major Tata for developing it for Indian requirements.
India is planning to indigenously develop a Futuristic Infantry Combat Vehicle (FICV) for the requirements of its Army and paramilitary personnel and Tata is expected to be one of the contenders for the contract.
