September 22, 2009: India has successfully tested a locally designed and manufactured 35mm anti-aircraft gun. India wants to replace hundreds of imported (in the 1970s) anti-aircraft guns 40mm guns. These fire 5.5 pound (2.5 kilogram) shells at the rate of 300 a minute. Max altitude is about 4,000 meters (13,000 feet). The Indian 35mm weapons system would also use an Indian radar and other locally made components.
A 35mm anti-aircraft weapon is already in use by Pakistan, where they manufacture, under, license, the Swiss Oerlikon weapon. India has also purchased technology and technical services from Oerlikon, for the development of the Indian 35mm autocannon. The 35mm shells weigh about 1.65 pounds (.75 kilograms) and have similar range to the older 40mm ones. This AAA (Anti-Aircraft Artillery) is still useful against helicopters and transports, and jets that are moving slowly over the battlefield.
