    Hi, I read that the French 25mm ATG was a bad weapon, but I think it has been given hard time when you consider that the Solothurn S-18/1000 was highly thought of, there were two different types of 25mm used by the French in 1940 (not counting AFV mounted and AA) and I can find the armour penetration data on the Hotchkiss but not the Puteaux,

    25mm L/77 mle 1934 Hotchkiss Anti-Tank Gun
    29mm @ 500m @ 30°


    25mm L/72 mle 1937 Puteaux Anti-Tank Gun
    ?? @ 500m @ 30°


    20mm Solothurn S-18/1000 Anti-Tank Rifle
    15mm @ 300m @ 30°


    As you can see the Hotchkiss can penetrate 29mm up to 500m, but the Solothurn can only Penetrate 15mm up to 300m, I dont know about the Puteaux with having a shorter barrel it may be less but I think both 25mm fired the same round.
    I hope this data is ok because sites differ and I cant remeber were I got this info from.
    Regards Yan.

    One problem with the 25mm guns was that their carriages were flimsy. The BEF found that ones issued to them (in the name of compatability with French equipment) were unsuitable for lorry towing and had to be porteed instead.

    I agree with your judgment. It was in fact a good weapon and could match the German 3,7-cm PaK 35/36 Pzgr 39 amno. The trouble was not performance but an excessive weight . This was corrected with the 1937 model. Unfortunately not enough were made and if on paper the French were most advanced in anti tank technology until 1940 , the lack of proper strategy and the ill use of their materials made the 25mm quite uneffective (for instance when mounted on the Panhard) .

    Here is more with some extra sources (both in English and in French )


    Canon léger de 25 m model 1934
    weight: 480 kg
    speed: 920 m/s
    weight of each shell : 0,320 kg
    Performances: 35 mm à 100 m, 29 mm à 500 m, 20 mm à 1 000 m at 30°
    - the 1937 matched the 310 kg battery

    Thanks Skipper, the site says that there was 2000 Hotchkiss Canon léger de 25 m model 1934, but how many of the Puteaux type 25mm were produced,
    The version mounted in the Panhard AMD-178, AMR-35 & AMC-34 had a shorter barrel, some data, but only up to 200m not 500m.
    Regards Yan.

    25mm L/47 SA-35 Gun
    · Elevation: -12° to +14°
    · Shell Weight: 320gr
    · Muzzle Velocity: 880 m/s
    · Rate of Fire: 15 r.p.m.
    · AP Capabilities: 32mm @ 200m @ 35°

    Ok I see, I don't know how many of the 1934 canons were produced, I'll try to dig it a bit. If I find more details I'll let you know.
