(14,779 posts)Sorry I am an old red leg arterrymen and I am familiar with Proximity fuses, times fuses and impact fuses. While I did NOT work on AA weapons or aircraft weapons, the fuses tend to be similar for the purpose of each fuse is the same, to go off when it does the most damage to something you want to hit.
My comment is the reports of blast is consistent with a warhead going off near the plane and hitting the plane with pieces of metal from the warhead. Who launched that warhead is something I avoiding discussing for those facts are NOT in the public domain.
The reports of damage is NOT consistent with Cannon or Machine Gun Fire for those are done in bursts of no more then 8 or 9 rounds (Weapons heat up to much if fired to much unless water cooled and the water has to be added all the time in such water cooled weapons, the main reason they were replaced as ground weapons in the 1960s, through the Russians did have an AA gun that used water cool cannons that they put into service in the 1960s).
Those two restrictions, the need to use water to cool down any fast shooting weapon if fired more then a few rounds at a time AND that targets are rarely within sight for more then a few seconds at a time, cannons and machine guns on planes rarely are fired for more then a few rounds at a time. To get the number of holes in the plane that has been reported takes a warhead, either a missile or a shell.
