    This I have always wondered about. What plane had the heaviest weight of fire in a 2 sec burst? Weight of fire meaning = most devastating fire. ME262 ? I want two answers here:
    1) Heaviest weight of fire for any plane meant for air to air combat (not ground attack planes). (anti bomber killer sure)
    2)Heaviest weight of fire for any plane meant for air superiority (this would be more just purely air superiority fighter not a bomber killing).

    No rockets here, give us one allied and axis plane for both 1, 2.

    Probably is the Me262A-1a, with 12.5 Kg per second of fire, and the second colud be the TA-152H-1, with 5,9 Kg
    On the other hand, the first had only eight and ten seconds of fire with the two couples of gun, and the Ta-152, 9 seconds of fire with the MK 108, and 14 seconds with the two 20 mm guns.

    What about a P.108A firing 102mm shells? I should think they weigh a lot ;)

    Interesting site Parm, bookmarked it. I spotted one error though, Spitfires weren't first delivered in July 1936 it was in July 1938.

    Nope, the first and I think only time it was fired it riped the front of the plane off and had to make an emergency landing :lol:

    Yup, it was originally intended to export money to Switzerland cheating on the Customs officers: plan was to load the ammo with money, fly above the alps and shoot at a purposedly designed Swiss bank caveau.

    Traditional methods of hiring locals to walk over the border at night proved more effective and less expensive.

    Loom, if it was for me the sad thing is that I did not drink...
    And even more sad I have lost my good arm at drinking, can't stand the quantity I used to when I was young and bold...

    Could be a justification to say that I wrote it after the preparation of the year end financial report?

    "Weight of Fire" has little meaning for a fighter aircraft. Perhaps you were thinking of battleships. :)

    i was thinking mostly fighter ac....but it should apply to any ac that can concentrate its firepower on a central target.

    Be interested in the specially outfitted B-25's as mentioned earlier, and also the original weapons configuration of the P-61.

    Centerline mounted weapons are inherently more effective then wing mounted weapons due to convergence and wing flexing. Loss of effectiveness increases as weapons are placed further from the fuselage.

    Generally speaking, explosive filler in cannon shells causes more damage then impact of the projectile itself. HE filler quantity varies greatly depending on who made the shells. Germany was famous / infamous for producing 20mm and 30mm shells with more HE filler then everyone else. 20mm Minengescho├č don't weigh more then 20mm solid shells but you will notice the difference 18g of HE filler makes when it blows a 2 foot hole in your aircraft wing.

    These are the reasons I think "Weight of fire" is meaningless when calculating aircraft firepower.
