    Been lurking for a while. Thought I'd pop my head in and say hi.

    Which plane do you think had the most guns that could be used to attack an opponent or ground targets?

    Wasn't there a Hurricane that had 12 machine guns?

    Yes the Hurricane MKIIB had 12 .303" machine guns. I am pretty sure one of the American twin engined bombers (B-25, B-26, A-26, A-20) carried 12 .50" machine guns but don't quote me on that.

    Welcome to the forum.

    There were B-25s that had 8 .50 cals in the nose, 4 more in blisters on the sides of the fuselage (2 on each side), and the top turret. So you could conceivably have 14 x .50 cals pointed at the enemy in a strafing attack.

    Ouch, maybe they should point that firepower at ships, not people. Might not be too humane to be hit by 14 50 cals. Imagine the first guy to be hit getting all 14 on him (shudder). Then again, it would be a great deterant from moving Jerries on open roads. :D
    PS welcome, and good post.

    Most of those outfitted that way were used in the Pacific against ships. Seems a bit overkill to go after people with that much. But in a troop concentration, highly effective.

    B-25 was highly effective against shipping, they also had that version with the artillery gun 75mm or something? Now that would rip it apart

    I have seen the results of the B25 attack in photos close up and it is scaryyyyyyy stuff. It was perhaps the scariest plane to be strafed by in the pacific.

    There was a version of the A-26 that carried 20 x .50's, I believe 18 of them could be aimed to the front for ground attack. As far as I know this was the most guns for strafing of any WWII plane.

    Yes there were B-25s with the 75mm cannon on board. But because they had to be hand loaded they had a low rate of fire. But when they hit, they would do some serious damage. We have a round for that gun in the museum made of wood that was used for loader practice. It is huge and heavy. I will see if I can get a pic of it to post in the next couple of weeks.

    It was 16 .50's. Eight packed into the nose, six in the wings (three in each wing) and two in the top turret that could be locked forward and fired by the pilot.

    Pretty devastating.

    The Beaufighter must run it a close second. 4 x 20 and 4 x HMG equal to 16 x HMG.

    There was another variant that had 8 guns mounted in underwing pods, 8 in the nose, and the top turret could be locked forward - which is 18. The version you describe was a later superior variant with the wing guns internalized.

    Don't think so. The variant you are referring to had only six forwrad firing guns as opposed to the eight on the A-26B-50-DL and later series so adding two more under the wings still gives you just 16. You said 18 could be brought to bear on a target.

    http://www.csd.uwo.ca/~pettypi/elevon/baugher_us/a26-03.html
    "A new all-purpose nose was installed beginning with the A-26B-10-DL. Initially, the USAAF was undecided about what armament this version should carry. As originally planned, it was expected that the A-26B would be fitted with a variety of alternate solid nose sections, and that one deemed to be the best would be selected. Options that were tested on early A-26Bs included one 75-mm cannon to starboard and two 0.50-inch machine guns to port; one 75-mm cannon to starboard and one 37-mm cannon to port; two 37-mm cannon with one on each side of the nose; one 37-mm cannon to starboard and two 0.50-inch machine guns to port; four 0.50-inch guns starboard and one 37-mm cannon to port; or four 0.50-inch guns to starboard and two 0.50-in guns to port. Eventually at the end of 1944, the USAAF finally made up its mind and decided that the solid-nosed A-26B would have six machine guns with 400 rounds per gun. The guns in the two turrets had 500 rounds each.

    Beginning with the A-26B-15, the forward-firing armament could be supplemented by eight 0.50-inch guns mounted in four twin packages underneath the outer wing panels.

    You can see the eight nose mounted guns and the three guns mounted in the right wing. You will not find any pictures of an eight gun nose mounting along with two dual .50 packs under each wing. With the dorsal trurret locked forward, that's 16 guns on target.

    At a cyclic rate of 750rpm, that's 200 rounds per second! If you were in a barge or small cargo vessel, you would literally be shredded.

    You appear to be correct. I'd not realized the 8 gun nose was never paired with the quad gun packs. Serves me right for not looking it up.

    One point - cyclic rate of fire for the .50 M2 Lightweight Aircraft gun was 750-850 rpm, with 800 being typical. 750 is usually the quoted figure, but if you check the rps figures for various planes, you will find the 6 gun fighters are rated at 80 rps = 4800 rpm / six guns = 800 rpm per gun. The only plane I've ever seen rps figures for which come to 750 rpm is the P-47 which is rated at 100 rps.

    Assumedly the RoF of the P-47 was tuned down because it had more guns, so this might apply to the A26. But my guess is that in the field they were all tuned the same (which involves the headspacing adjustment) so 800 rpm is the proper figure.
