|L-70 anti-aircraft gun|
Talks between India and China have broken down and two are preparing for a high altitude fight. India has upgraded their L-70 anti-aircraft gun to be able to shoot down drones. The L-70 is basically the same Bofors 40mm gun that has been in use since the 1930s. What got my attention is that it can shoot 300 rounds per minute. Actually it is extremely unlikely that it could keep that up that rate for more than a few seconds. Shells come in clips of five which are loaded by hand. You would need a well trained crew to keep that thing fed if it was firing continuously. And if you did manage to fire for more than a few seconds, overheating the barrel would become a problem. A better measure would be five rounds per second. If you can't hit a drone with five rounds, more is not going to help. I looked for a video, but I did not find a good one. Here's a good pic.
P.S. Google read my mind and served up this video on YouTube. It's pretty good.
